CLF-C02 In-Scope Services in Exam Guide Version 1.3: What Was Added, Dropped and Renamed

AWS's exam guide is the official syllabus for CLF-C02, and it has changed since many courses were built. The web version on docs.aws.amazon.com is at version 1.3, and its service lists differ in dozens of places from the original CLF-C02 guide: the version 1.0 PDF, which still compares CLF-C02 with the CLF-C01 exam it replaced on September 19, 2023. Comparisons below are Passy's, made side by side on October 28, 2026.

What the CLF-C02 service lists are, and what they are not

The In-Scope AWS Services page of version 1.3 names 111 services and features in 19 categories (Passy's count). AWS calls the list "non-exhaustive" and "subject to change," and a separate out-of-scope list names 48 services you are not expected to know.

Four official rules from AWS's Certification FAQ and the guide's revision page frame how to use them:

• Guide first, exam later. The revision page says exam guide updates are published about one month before they are reflected on the exam; the FAQ says at least one month.
• New services wait. A new product, service or feature must be generally available for 3 months before it can appear on any AWS exam.
• Changed services are replaced. When a service changes, AWS replaces the exam questions affected by the change.
• If a question seems out of date, AWS's advice is to "choose the best available answer from the options in the question."

The 2026 revisions to the CLF-C02 exam guide

The guide's revision page lists four versions:

This table's version 1.0 (June 24, 2026) is a different document from the 2023 PDF that also carries the label version 1.0. When Passy checked on October 28, 2026, the web pages and the guide's PDF download already showed version 1.3 in the table.

What version 1.3 itself changed

The revision page records one change in detail: eight services removed from the out-of-scope list (Amazon Elastic Transcoder, AWS Elemental MediaStore, Amazon Lookout for Metrics, Amazon Lumberyard, Amazon Monitron, AWS Panorama, AWS RoboMaker and Amazon WorkDocs). Removing a service from the out-of-scope list does not put it in scope; none of the eight appears on the in-scope list.

Passy also compared the version 1.3 pages with archived copies of the same pages from September 27, 2026, after version 1.2 was published. Version 1.3 adds or removes no domain, weighting, task statement or in-scope service. Apart from the eight removals, it edits names only: the analytics service is now written "Amazon Quick," and some task statements drop an "Amazon" or "AWS" prefix. If you studied from version 1.2, nothing you learned is out of date.

Which version applies to your exam

With the one-month lead described above, version 1.3 is the guide for exams from about the end of November 2026, and for 2027 unless AWS publishes another revision. AWS published four revisions between June and October 2026, so reread the revision page a few weeks before your exam. As of October 28, 2026, AWS's Coming soon page announced no successor to CLF-C02.

AWS Support plan names on CLF-C02: the change most likely to cost points

Task statement 4.3 asks you to identify AWS Support options, and its examples changed:

• 2023 guide (version 1.0 PDF): customer service and communities, AWS Developer Support, AWS Business Support, AWS Enterprise On-Ramp Support, AWS Enterprise Support
• Version 1.3: customer service and communities, Basic Support, AWS Business Support+, AWS Enterprise Support, AWS Unified Operations

Archived copies of the Domain 4 page show the old names still in place on June 29, 2026 and the new ones by September 27, 2026, so the switch came with version 1.1 or 1.2. A course updated in the first half of 2026 can still teach the old plans.

Enterprise Support appears in both lists; AWS says its existing subscribers can use the plan's new features at any time. AWS announced Business Support+, Enterprise Support and Unified Operations in its December 2, 2025 News Blog post, which says subscribers of Developer Support, Business Support (classic) and Enterprise On-Ramp Support "can continue to receive their current level of support through January 1, 2027." AWS's Trusted Advisor documentation adds that the three older plans remain available in the AWS GovCloud (US) Region. For an exam in 2027, learn the four current names.

AWS's plan comparison page positions them this way, as checked on October 28, 2026:

If your course teaches the old four-plan ladder, learn the new names and positioning, and treat old practice questions about Developer or Enterprise On-Ramp as outdated. The rest of task 4.3 still applies: Trusted Advisor, the AWS Health Dashboard and Health API, the AWS Trust and Safety team for abuse reports, AWS Partners and Marketplace, re:Post, Knowledge Center and Prescriptive Guidance, AWS Professional Services and solutions architects.

Services the current CLF-C02 guide adds

Compared with the 2023 version 1.0 in-scope list, these appear on the version 1.3 in-scope list:

All nine were already listed in the archived June 29, 2026 copy, so a course refreshed in 2026 probably covers them. ElastiCache also appears in task statement 3.4 as the example of a memory-based database, a slot the 2023 guide left without an example.

At this level, the exam guide's skill statements are about recognizing which service fits a need, such as choosing a network connectivity option or a memory-based database. You can check how the planned CLF-C02 scenarios ask you to pick the right service in the sample questions on the exam page.

Services moved to the CLF-C02 out-of-scope list

These were in scope in the 2023 version 1.0 and now sit on the out-of-scope list:

• Analytics: AWS Data Exchange, Amazon Managed Streaming for Apache Kafka (Amazon MSK)
• Cost and customer enablement: AWS Billing Conductor, AWS Activate, AWS IQ, AWS Managed Services (AMS), which version 1.3 writes as "Amazon Managed Services (AMS)"
• Compute and databases: AWS Wavelength, Amazon MemoryDB, AWS AppConfig
• Developer tools: AWS CloudShell, AWS CodeArtifact, AWS CodeDeploy, AWS Device Farm
• Other: AWS IoT Greengrass, AWS Launch Wizard, AWS Transfer Family, AWS Network Firewall

If a course spends time on any of these, you can skim that section.

Services no longer on either CLF-C02 list

Nine services from the 2023 in-scope list appear on neither current list: AWS Local Zones, AWS Cloud9, AWS CodeCommit, AWS CodeStar, AWS AppSync, Amazon Kendra, AWS Resource Groups and Tag Editor, AWS Snow Family and AWS Audit Manager. Four of them, AppSync, Kendra, Snow Family and Audit Manager, were still on the in-scope list on June 29, 2026 and gone by September 27, 2026, according to the archived copies.

Because both lists are non-exhaustive, "not listed" is weaker than "out of scope." Give these low priority rather than none: know in a sentence what each does if your course covered it, and spend real time elsewhere.

New service names to recognize on CLF-C02

Version 1.3 uses names that differ from the 2023 wording:

Expect the current names on the exam, and connect them to what you learned under the old ones.

A 20-minute audit of an older CLF-C02 course or note set

1. Check the date. If your course or notes predate September 2026, assume the support-plan lesson is outdated, and expect lessons on Snowball, AppSync, Kendra or Audit Manager that you can skim.
2. Open the current in-scope page and tick each category against your materials. Anything listed that your course never mentioned (for example ElastiCache, DocumentDB, Transit Gateway, PrivateLink, Client VPN or Amazon Q) goes on a short "learn" list.
3. Open the out-of-scope page and cross out sections of your course on those services.
4. Read task statements 3.4, 3.7, 3.8 and 4.3 word for word. They contain most of the renamed and new examples.
5. Recheck practice questions that mention retired plan names or services no longer listed; skip them rather than memorize their answers.

To spot gaps faster, try Passy's free CLF-C02 practice questions and note any service that feels new. Planned full prep for this exam is built on the CLF-C02 exam guide's content outline, and you can see the four-domain outline the planned CLF-C02 prep follows on the exam page.

How the CLF-C02 service changes fit your study plan

Most of the added services belong to Domain 3 (Cloud Technology and Services, 34% of scored content), and the support plans belong to Domain 4 (12%). Fold the "learn" list from your audit into those weeks of your plan instead of adding a separate block. The CLF-C02 study time guide shows where each domain sits in a 2-, 4- or 6-week plan, and the CLF-C02 billing tools guide covers the rest of Domain 4 that sits next to the support plans.

For the recall side, the CLF-C02 flashcards planned for in-scope services and Well-Architected concepts are designed for this kind of service-name review once full prep launches.
