Question 76 clf-billing-basics-076

Intermediate · Choose one

Which Trusted Advisor checks are available to a customer on the Basic Support plan?

  1. a All checks in the service limits category, plus selected checks in the security and fault tolerance categories
  2. b All Trusted Advisor checks in every category
  3. c No Trusted Advisor checks at all
  4. d Only the cost optimization checks
Show answer & explanation

Answer: A

Why A is correct

AWS gives every customer, including those on Basic Support, all checks in the service limits category plus a selected set of security and fault tolerance checks such as MFA on the root account, Amazon S3 bucket permissions, and unrestricted specific ports in security groups. These are the checks where the risk of not seeing them is highest. Access to the full library of checks, along with automatic check updates and the Trusted Advisor API, requires a paid plan.

Why the others are wrong

  • B — Full access to all Trusted Advisor checks requires AWS Business Support+, AWS Enterprise Support, or AWS Unified Operations.
  • C — Basic Support does receive a meaningful subset of checks, so Trusted Advisor is not entirely unavailable.
  • D — Cost optimization checks are part of the full check set available on paid plans. They are not what Basic Support receives.

Question 77 clf-billing-basics-077

Intermediate · Choose one

According to AWS Support case severity definitions, what is the target first-response time for a case classified as 'Production system down'?

  1. a Four hours
  2. b One hour
  3. c 12 hours
  4. d 24 hours
Show answer & explanation

Answer: B

Why B is correct

AWS defines five severity levels with published first-response targets: general guidance at 24 hours, system impaired at 12 hours, production system impaired at four hours, production system down at one hour, and business-critical system down measured in minutes. Production system down means important functions of the application are unavailable and the business is significantly impacted, which is why AWS targets a one-hour first response. All of these severity levels require a paid support plan.

Why the others are wrong

  • A — Four hours is the target for 'production system impaired', where important functions are degraded rather than unavailable.
  • C — 12 hours is the target for 'system impaired', which covers non-critical functions behaving abnormally or a time-sensitive development question.
  • D — 24 hours is the target for 'general guidance', which covers development questions and feature requests.

Question 78 clf-billing-basics-078

Intermediate · Choose one

A company requires 24x7 access to Cloud Support Engineers by phone, web, and chat, full access to AWS Trusted Advisor checks, and use of the AWS Support API, but it does not need a designated Technical Account Manager. Which AWS Support plan meets these requirements at the lowest cost?

  1. a Basic Support
  2. b AWS Unified Operations
  3. c AWS Business Support+
  4. d AWS Enterprise Support
Show answer & explanation

Answer: C

Why C is correct

AWS Business Support+ is the entry point for full technical support. It provides 24x7 phone, web, and chat access to Cloud Support Engineers, an unlimited number of cases opened by any user with permissions, the complete set of Trusted Advisor checks, the AWS Support API, and third-party software support, with a documented minimum of USD 29 per month per account. Because the requirement stops short of a designated TAM, paying for a higher plan would buy capability the company has said it does not need.

Why the others are wrong

  • A — Basic Support cannot open technical support cases and gives only a subset of Trusted Advisor checks, so it fails several of the stated requirements.
  • B — AWS Unified Operations adds managed incident response with Incident Management Engineers and a Domain Specialist Engineer, at the highest minimum commitment of all the plans.
  • D — AWS Enterprise Support meets every requirement but adds a designated TAM, strategic business reviews, and a 15-minute business-critical response target, at a substantially higher minimum monthly charge.

Question 79 clf-billing-basics-079

Intermediate · Select 2 answers

Which TWO capabilities require a paid AWS Support plan rather than Basic Support? (Choose TWO.)

  1. a Opening a technical support case about the behavior of an AWS service
  2. b Viewing the AWS Health Dashboard
  3. c Using the AWS Health API to integrate AWS Health events with in-house systems
  4. d Receiving AWS Health events through Amazon EventBridge
  5. e Requesting an increase to a service quota
Show answer & explanation

Answer: A and C

Why A and C are correct

Two things reliably sit behind the paid support boundary. Technical support cases are unavailable on Basic Support entirely, and programmatic access to AWS Health through the AWS Health API requires AWS Business Support+, AWS Enterprise Support, or AWS Unified Operations. Both are about depth of engagement with AWS rather than visibility, which is the pattern that explains where AWS draws the line.

Why the others are wrong

  • B — The AWS Health Dashboard is available to all AWS customers at no additional cost and requires no setup.
  • D — AWS Health events are delivered through Amazon EventBridge to all customers at no additional cost, with no support plan requirement.
  • E — Service limit increase requests are one of the case types explicitly available to every customer, including those on Basic Support.

Question 80 clf-billing-basics-080

Intermediate · Choose one

A company needs to know whether a degraded AWS service is affecting the specific Amazon EC2 instances and Amazon RDS databases in its own account, and it wants to react automatically when such an event is published. Which combination should it use?

  1. a The account view of the AWS Health Dashboard for visibility, with AWS Health events delivered to Amazon EventBridge to trigger automation
  2. b AWS CloudTrail event history, filtered for AWS service events
  3. c Amazon CloudWatch alarms on instance status checks, with Amazon SNS notifications to the operations team
  4. d AWS Trusted Advisor fault tolerance checks, reviewed on a weekly schedule
Show answer & explanation

Answer: A

Why A is correct

The account-specific view of the AWS Health Dashboard reports events that affect the customer's own resources, rather than only general service status, which is what makes it possible to tell whether a problem is theirs or AWS's. Delivering those same AWS Health events to Amazon EventBridge, which is available to all customers at no additional cost, allows the company to trigger automated responses such as failover or notification without polling a dashboard.

Why the others are wrong

  • B — CloudTrail records API calls made in the account. It is not a feed of AWS service health events.
  • C — CloudWatch alarms detect that a resource is unhealthy but cannot tell the team that AWS has published an event explaining why or when it will be resolved.
  • D — Trusted Advisor evaluates configuration against best practices on a periodic basis. It is not a channel for real-time service event notification.

Question 81 clf-billing-basics-081

Hard · Choose one

AWS restructured its support plans in December 2025. Which statement reflects the current arrangement?

  1. a The AWS Developer Support, AWS Business Support, and AWS Enterprise On-Ramp plans are being discontinued on January 1, 2027, and AWS Business Support+, AWS Enterprise Support, and AWS Unified Operations are the current paid plans alongside Basic Support
  2. b Basic Support has been withdrawn, so every AWS account now requires a paid support plan
  3. c AWS Developer Support and AWS Enterprise On-Ramp remain the recommended entry-level and mid-tier plans for new customers
  4. d AWS has consolidated all paid support into a single plan with usage-based pricing
Show answer & explanation

Answer: A

Why A is correct

AWS restructured its support portfolio in December 2025. The current lineup is Basic Support plus three paid plans: AWS Business Support+, AWS Enterprise Support, and AWS Unified Operations. The legacy AWS Developer Support, AWS Business Support, and AWS Enterprise On-Ramp plans closed to new subscriptions and are being discontinued on January 1, 2027, with Enterprise On-Ramp customers upgraded to AWS Enterprise Support during 2026. The legacy plans remain available in the AWS GovCloud (US) Region. Candidates should recognize both the legacy and the current names, because study material written before the change still uses the old lineup.

Why the others are wrong

  • B — Basic Support remains included with every AWS account at no additional charge.
  • C — Both of those plans are on the retirement path and are closed to new subscriptions. AWS directs Developer Support customers to AWS Business Support+ and Enterprise On-Ramp customers to AWS Enterprise Support.
  • D — AWS continues to offer several distinct paid plans differentiated by response time, technical engagement, and managed operations, not a single consolidated plan.

Question 82 clf-billing-basics-082

Hard · Choose one

A company has a workload where any interruption puts the business at immediate risk. It needs a designated Technical Account Manager together with a published first-response target of under 15 minutes for business-critical system down cases, at the lowest cost that satisfies both requirements. Which plan should it choose?

  1. a AWS Business Support+ with a production system down case, which targets a response within one hour
  2. b Basic Support, escalated by phone to the AWS Support Center
  3. c AWS Enterprise Support, which targets a response of under 15 minutes for business-critical system down cases
  4. d AWS Business Support+, which targets a response of under 30 minutes for business-critical system down cases
Show answer & explanation

Answer: C

Why C is correct

The business-critical system down severity is reserved for situations where critical application functions are unavailable and the business is at risk, and AWS targets a first response of under 15 minutes at the AWS Enterprise Support level, which also provides the designated Technical Account Manager. AWS Unified Operations goes further still, with a five-minute response from an Incident Management Engineer and a designated TAM and Domain Specialist Engineer, but at a far higher minimum monthly commitment than the requirement calls for. The severity level and the plan work together: choosing the right severity earns the target response, and the plan determines what that target is.

Why the others are wrong

  • A — A one-hour target corresponds to the 'production system down' severity, which is a lower severity than 'business-critical system down' and therefore a slower target.
  • B — Basic Support cannot open technical support cases at all, so no technical response target applies.
  • D — AWS Business Support+ targets under 30 minutes for the same severity, which is slower, and it does not include a designated Technical Account Manager.

Question 83 clf-billing-basics-083

Hard · Select 2 answers

Which TWO statements about AWS Trusted Advisor are correct? (Choose TWO.)

  1. a Its checks are grouped into categories that include cost optimization, security, fault tolerance, performance, service limits, and operational excellence
  2. b Full access to all Trusted Advisor checks, along with the Trusted Advisor API, requires a paid AWS Support plan
  3. c It replaces AWS Cost Explorer as the primary tool for analyzing historical spend
  4. d It automatically remediates every finding it reports without customer action
  5. e It is available only to accounts that are members of an AWS Organizations organization
Show answer & explanation

Answer: A and B

Why A and B are correct

Trusted Advisor is an advisory engine, and both of these statements define its shape. The six categories tell a candidate what kinds of question it answers, and the support plan boundary tells them who gets the full answer. Every customer sees all service limits checks plus selected security and fault tolerance checks; the complete library, automatic check updates, and the Trusted Advisor API come with AWS Business Support+, AWS Enterprise Support, or AWS Unified Operations.

Why the others are wrong

  • C — Trusted Advisor identifies optimization opportunities such as idle resources; it does not report cost by service and time period. AWS Cost Explorer remains the tool for analyzing spend.
  • D — Trusted Advisor produces recommendations. Acting on them is the customer's responsibility, though some findings can be automated through other services.
  • E — Trusted Advisor is available to standalone accounts as well. AWS Organizations membership affects organizational reporting views, not eligibility.

Question 84 clf-billing-basics-084

Hard · Choose one

A company is preparing for a product launch that will drive a large, temporary spike in traffic. It wants AWS to provide architectural and scaling guidance in the run-up to the event and dedicated attention during it. Which AWS Support offering is designed for this?

  1. a A service quota increase request submitted through the AWS Support Center
  2. b AWS Countdown, which provides specialist-led support around critical business events
  3. c An AWS Trusted Advisor performance category review scheduled for the launch date
  4. d AWS Professional Services, which is the only route to any AWS event assistance
Show answer & explanation

Answer: B

Why B is correct

AWS Countdown is the event management offering within AWS Support, providing specialist-led guidance in the planning phase and dedicated attention during a critical business event such as a launch, migration cutover, or seasonal peak. AWS introduced it as the successor to the earlier Infrastructure Event Management offering, and it is the current event management offering within AWS Support. Base AWS Countdown is included with AWS Enterprise Support, and AWS Countdown Premium is available as a paid add-on for AWS Business Support+ and AWS Enterprise Support customers and is included as a recurring subscription with AWS Unified Operations.

Why the others are wrong

  • A — A quota increase may well be a necessary preparation step, but on its own it is an administrative request rather than architectural and scaling guidance.
  • C — Trusted Advisor runs automated checks and produces findings. It does not provide human engagement or event-specific planning.
  • D — AWS Professional Services delivers project-based consulting engagements and is a legitimate option for some work, but it is not the AWS Support offering designed specifically for critical event readiness, and it is not the only route to event assistance.

Question 85 clf-billing-basics-085

Hard · Choose one

A developer on a Basic Support account posts a technical question and receives no reply from the community. Which statement about escalation is correct?

  1. a AWS automatically converts any unanswered community question into a technical support case after 24 hours, on any support plan
  2. b The developer can open a technical support case at the general guidance severity, which is available on Basic Support
  3. c The account must be upgraded to a paid support plan before a technical support case can be created; unanswered questions are routed to AWS Support engineers only for customers who already have a paid plan
  4. d The developer should submit the question through the AWS abuse report form so that AWS Trust and Safety can route it to an engineer
Show answer & explanation

Answer: C

Why C is correct

Basic Support does not permit technical support cases under any severity, so the only path to an AWS engineer for a technical question is to move to a paid plan. AWS re:Post is free and open to everyone, and AWS documents that questions from AWS Premium Support customers which the community does not answer are passed to AWS Support engineers. That routing is a benefit of already holding a paid plan, not a substitute for one.

Why the others are wrong

  • A — No automatic conversion exists on any plan, and it certainly does not create case entitlements that the account's support plan does not include.
  • B — General guidance is a severity level available within paid support plans. Basic Support customers cannot create technical cases at any severity.
  • D — The abuse report form exists for reporting abusive use of AWS resources to the AWS Trust and Safety team. It is not a technical support channel.

Question 86 clf-billing-basics-086

Easy · Choose one

Where can a company search listings from independent software vendors to find, test, buy, and deploy third-party software that runs on AWS?

  1. a AWS Marketplace
  2. b AWS Partner Central
  3. c AWS Service Catalog
  4. d AWS Artifact
Show answer & explanation

Answer: A

Why A is correct

AWS Marketplace is the curated digital catalog where customers find, test, buy, and deploy software and data products from independent software vendors and other AWS Partners. Purchases are made against the customer's existing AWS account and the charges appear on the AWS bill, which removes a separate procurement and payment relationship with each vendor. Free trials, pay-as-you-go, annual contracts, and privately negotiated offers are all supported.

Why the others are wrong

  • B — AWS Partner Central is the portal AWS Partners use to manage their partnership, access training, and register opportunities. Customers buy through AWS Marketplace.
  • C — AWS Service Catalog lets an organization curate and govern its own approved products for internal deployment. It manages what a company's own teams may launch, not what is available to buy from third parties.
  • D — AWS Artifact provides on-demand access to AWS compliance reports and agreements. It has no software catalog.

Question 87 clf-billing-basics-087

Easy · Choose one

Which AWS resource is a free community question-and-answer service where AWS customers, partners, and employees share knowledge, and which now also hosts the AWS Knowledge Center articles?

  1. a AWS Support Center
  2. b AWS Artifact
  3. c AWS Prescriptive Guidance
  4. d AWS re:Post
Show answer & explanation

Answer: D

Why D is correct

AWS re:Post is the community question-and-answer service that replaced the original AWS Forums, and the AWS Knowledge Center articles were migrated into it. It is part of the AWS Free Tier and free to use: anyone can browse, and posting requires an AWS account. AWS also notes that questions from AWS Premium Support customers which the community does not answer are passed on to AWS Support engineers.

Why the others are wrong

  • A — The AWS Support Center is the console where customers create and manage support cases with AWS. It is not a community forum.
  • B — AWS Artifact is the self-service portal for AWS compliance reports and agreements.
  • C — AWS Prescriptive Guidance publishes strategies, guides, and patterns authored by AWS technology experts. It is curated content rather than a community question-and-answer service.

Question 88 clf-billing-basics-088

Easy · Choose one

A company wants to read AWS technical content on architectural best practices, including whitepapers and reference architecture diagrams, before designing a workload. Where is this content published?

  1. a Only in AWS Marketplace, as paid listings from independent software vendors
  2. b Only in AWS Artifact, alongside compliance reports
  3. c On the official AWS website, in the AWS Whitepapers and Guides library and the AWS Architecture Center
  4. d Only within the AWS Support Center, after a support case is opened
Show answer & explanation

Answer: C

Why C is correct

AWS publishes technical whitepapers, decision guides, technical guides, and reference architecture diagrams openly on its website, through the AWS Whitepapers and Guides library and the AWS Architecture Center. Making this material public and free is deliberate: architects can research, compare designs, and build internal standards without an account, a support plan, or a sales conversation.

Why the others are wrong

  • A — AWS Marketplace sells third-party software and data products. AWS's own whitepapers and reference architectures are not listings there.
  • B — AWS Artifact provides compliance reports such as SOC and ISO documentation and AWS agreements, not architectural guidance.
  • D — Support cases are for account, billing, service limit, and technical issues. Architectural content is published openly and does not require a case.

Question 89 clf-billing-basics-089

Easy · Choose one

A customer discovers that an application hosted on AWS is sending spam and wants to report it. Which AWS team handles reports of abuse of AWS resources?

  1. a The AWS Partner Network team, reached through AWS Partner Central
  2. b The AWS Professional Services team, reached through an engagement request
  3. c The customer's assigned Technical Account Manager, reached by email
  4. d The AWS Trust and Safety team, reached through the AWS abuse report form
Show answer & explanation

Answer: D

Why D is correct

The AWS Trust and Safety team investigates reports of abusive activity involving AWS resources, and customers submit them through the AWS abuse report form. AWS documents four abuse categories: objectionable or infringing web content, abusive email or spam, problematic network activity such as denial-of-service traffic, intrusion attempts, or port scanning, and content subject to DMCA removal requests. Anyone can file a report; it does not require a support plan.

Why the others are wrong

  • A — The AWS Partner Network manages the partner community and its programs. It is unrelated to abuse reporting.
  • B — AWS Professional Services is AWS's consulting organization, which delivers project-based design, migration, and build engagements. It has no abuse handling role.
  • C — A Technical Account Manager supports the customer's own environment and is available only with the top support plans. Abuse reports go to Trust and Safety, and anyone can file one.

Question 90 clf-billing-basics-090

Intermediate · Choose one

What is the role of an independent software vendor in the AWS Partner Network?

  1. a An AWS internal team that delivers paid migration engagements
  2. b An organization authorized to issue AWS Certifications on behalf of AWS
  3. c An organization that develops its own software products, which it can list and sell to AWS customers through AWS Marketplace
  4. d An organization that provides consulting and integration services to design and build AWS workloads for customers
Show answer & explanation

Answer: C

Why C is correct

An independent software vendor builds and sells its own software. Within the AWS Partner Network these organizations sit on the Software Path, where they qualify their products with AWS and reach customers through AWS Marketplace. The distinction from a services partner is what the organization sells: an ISV sells a product, a systems integrator sells expertise and delivery.

Why the others are wrong

  • A — AWS Professional Services is AWS's own consulting organization, not a partner. Partners are third-party companies.
  • B — Delivering AWS training is the Training Path. AWS Certification itself is administered by AWS, not by ISVs.
  • D — Consulting and integration describes a systems integrator or consulting partner, which sits on the Services Path of the AWS Partner Network.
