AD0-E725 Adobe

Adobe Commerce Developer Professional

Applications track

A developer level credential for the Adobe Commerce platform, previously known as Magento 2. It checks whether you can extend the application with modules, work with the admin and storefront layers, and integrate the store with external systems.

Knowledge areas

  • Module structure and dependency injection
  • Catalog data model, EAV attributes and product types
  • Checkout, quote and order flow customization
  • Plugins, observers, events and preferences
  • REST and GraphQL API integration
  • Theme layout, blocks and templates
  • Caching, indexing and performance tuning
  • Configuration scopes and admin permissions

Suggested approach

Work in a local Commerce instance rather than reading only. Build a small module that adds a custom order attribute, expose it through the API, then trace how cache and index invalidation affect what the storefront returns.

QSA_New_V4 PCI Security Standards Council

Qualified Security Assessor Qualification, Version 4 Line

Security track

An assessor qualification covering the PCI DSS v4.x standard and the assessment process itself. It is aimed at people who evaluate cardholder data environments and produce compliance reporting.

Knowledge areas

  • PCI DSS v4.x requirement families and intent
  • Assessment procedures, evidence and testing methods
  • Scope definition and network segmentation validation
  • Compensating controls and the customised approach
  • Report on Compliance and Attestation of Compliance
  • Requirement 8 identity, authentication and MFA
  • Requirement 10 logging, monitoring and time sync
  • Secure software development and vulnerability management

Suggested approach

Map each requirement family to its testing procedures and write down the evidence you would collect as an assessor. Practise scoping decisions, because determining what is inside the cardholder data environment drives almost every later judgement.

B2C-Commerce-Architect Salesforce

B2C Commerce Architect

Salesforce track

A solution design credential for Salesforce B2C Commerce. The focus is architecture and trade offs across storefronts, integrations and operations rather than day to day configuration.

Knowledge areas

  • Realms, instances, sites and multi storefront topology
  • Catalog, pricing, promotions and inventory design
  • Order management and OCAPI or Commerce API integration
  • LINK cartridges and third party integrations
  • Page Designer, content slots and SEO structure
  • Sandbox, staging and production environments
  • Caching strategy and storefront performance
  • Roles, permissions and account security

Suggested approach

Prepare to justify decisions, not to recall menus. Sketch a multi site and multi locale storefront, then explain how caching, search, promotions and integration points behave when traffic scales or a partner service fails.

1Z0-580 Oracle

Oracle Financials Essentials

Oracle track

An Oracle Financials assessment covering the core structure of the financial applications and the flows that move transactions from subledgers into the general ledger.

  • Ledgers, business units and chart of accounts design
  • Subledger accounting and journal creation
  • Payables, receivables and cash management basics
  • Period close and reconciliation routines
  • Financial reporting and inquiry tools
  • Approval routing and internal controls
  • Configuration versus customization decisions
  • Data security roles in financial applications

Suggested approach

Follow one transaction end to end, for example an invoice through payment, subledger accounting and into the general ledger. Understanding that chain makes configuration questions much easier to reason through.

CRL Check Point

Certificate Revocation List Administration

Security track

A Check Point administration topic exam focused on certificate handling, revocation and how public key infrastructure supports VPN and management traffic.

Knowledge areas

  • Certificate lifecycle, enrollment and renewal

  • IKE and IPSec certificate based authentication
  • Trust chains and validation failures
  • Object and policy management in SmartConsole
  • Expired or revoked certificate troubleshooting
  • Clock synchronisation and log correlation

Suggested approach

Draw a small PKI map for your own lab and walk through what happens when a gateway certificate expires mid session. Check Point specific behaviour around management objects matters as much as generic PKI theory.

KCNA Linux Foundation and CNCF

Kubernetes and Cloud Native Associate

Cloud & DevOps track

An entry level cloud native credential from the Linux Foundation and CNCF. It verifies broad working knowledge of Kubernetes and the surrounding cloud native ecosystem rather than deep hands on administration.

  • Cluster networking, CNI, ingress and DNS
  • Volumes, persistent storage and storage classes
  • Configuration, secrets and environment injection
  • Scheduling, node selectors, requests and limits
  • Observability, RBAC basics, Helm and GitOps

Suggested approach

Install a local cluster with kind or minikube and run kubectl until the vocabulary feels physical. Deploy an app, expose it, read its logs, and deliberately break a pod to see how the controller responds.

Apple-Device-Support Apple

Apple Device Support

Applications track

A support credential for people who deploy, maintain and troubleshoot Apple devices in business and education environments.

  • Networking, certificates and VPN configuration
  • Diagnostics, recovery, restore and safe mode
  • Mail, calendar and collaboration services
  • Issue triage, documentation and escalation

Suggested approach

Rehearse real support flows such as a Mac that will not boot, an iPhone stuck at activation lock, or a managed profile that will not apply. Apple tests judgement in a support conversation as much as feature knowledge.

1Z0-520 Oracle

Oracle E-Business Suite Payables

Oracle track

An Oracle E-Business Suite Payables assessment covering the procure to pay cycle, AP setup and the accounting path into the general ledger.

  • Payment batches, formats and disbursement
  • Prepayments and expense reports
  • Subledger accounting and journal transfer
  • Period close, accruals and reconciliation
  • Audit trail and segregation of duties

Suggested approach

Learn the transaction path before the screens. When you know how a two way match differs from a three way match and why a hold appears, most configuration questions resolve themselves.

OG0-091 The Open Group

  • DHCP, DNS, SNMP, NTP and QoS
  • ACLs, wireless architectures and device hardening
  • Virtualisation, cloud and container concepts
  • REST APIs, JSON and Cisco IOS automation

Suggested approach

Subnet until it is reflexive, then build packet tracer labs for switching and routing. Most candidates lose marks on troubleshooting items, so practise identifying the failing layer from a small set of symptoms.

1Z0-1163-1 Oracle

Oracle Accounting Hub Cloud Implementation Professional

Oracle track

An implementation credential for Oracle Accounting Hub Cloud, the service that registers external transaction systems and produces accounting entries from their data.

Compare this exam guide with the 201 line and study the differences first, since that is where new questions usually appear. Practise debugging a failing flow and reading the resulting error output.

Preparation guide

How to prepare for a certification exam

A practical sequence that works across vendors, from the first look at the exam guide through to exam day.

  1. 01

    Read the official exam guide before anything else

    Download the current objectives and weightings from the certification vendor. Sort every topic into three buckets: confident, partial and unknown. That split determines how your hours are spent, not the table of contents of a book.

  2. 02

    Build a schedule you can actually keep

    Work backwards from the exam date and block fixed study slots of 45 to 90 minutes. Protect two lighter days per week so one missed session does not collapse the plan. Put the date in your calendar with a reminder one week out.

  3. 03

    Learn the concepts before you memorise anything

    Understand why a technology behaves the way it does. Memorised facts fail as soon as a question changes one variable, while conceptual understanding lets you reason through wording you have never seen.

  4. 04

    Study official documentation, not summaries only

    Vendor documentation is the source the exam was written from. Read the sections that map to your weak buckets, and keep a running note of limits, defaults and configuration order, since those details are commonly tested.

  5. 05

    Build practical understanding in a lab

    Set up the smallest working version of the technology. A free tier account, a virtual machine or a local cluster is enough. Doing a task once teaches more than reading about it five times.

  6. 06

    Practise questions responsibly

    Use practice material to find gaps, not to memorise answers. After every question, write one line explaining why the correct option is right and why each distractor is wrong. Skip any source you cannot verify.

  7. 07

    Review weak areas on a cycle

    Keep a single error log with the topic, what you got wrong and the correct reasoning. Revisit entries after one day, then three days, then a week. Spaced repetition of your own mistakes is the fastest way to close gaps.

  8. 08

    Run timed practice sessions

    Sit one full length session under exam timing, with no notes and no pausing. Record how long each question takes. Timing pressure changes your accuracy more than most candidates expect.

  9. 09

    Track preparation progress with numbers

    Log scores by domain rather than overall. A flat average hides a domain stuck at 40 percent. Trend lines per topic tell you when you are genuinely ready and when you are only comfortable.

  10. 10

    Revisit difficult topics deliberately

    Return to the two or three topics you keep avoiding. Explain each one out loud or write a short summary as if teaching a colleague. Anything you cannot explain simply is still a gap.

  11. 11

    Manage the final week and exam day

    Taper study volume in the last three days. Review your error log and reference sheets only. Sleep properly, confirm the exam logistics, arrive early, and flag uncertain questions for review instead of stalling on the first pass.

The single most useful habit

Keep one error log for the whole preparation period. Every question you get wrong becomes a single line with the topic, the mistake and the correct reasoning. Reviewing your own mistakes on a spaced cycle teaches faster than any volume of new material, and it shows you exactly when you are ready.

How to use this library

Each card is written for one exam code. The summary explains the subject area, the knowledge list shows the topics candidates usually need, and the suggested approach describes a way to turn reading into practice. The resource links beneath each card point to third party pages that were supplied with the exam code and are listed here without modification.

Where an exam code is ambiguous or has been retired, the card says so and points you back to the vendor page. Exam objectives, formats, durations and passing scores change, so always confirm the current details with the certification vendor before you schedule.

Before you book an exam

  • Confirm the exam code, version and current objectives on the vendor site
  • Check prerequisites, retake policy and any experience requirements
  • Verify the vendor policy on third party study material before you use it
  • Match your study hours to the published domain weightings
  • Complete at least one full timed practice session under exam conditions
  • Confirm testing centre or online proctoring requirements in advance

Questions

Frequently asked preparation questions

Short practical answers to the questions candidates ask most often before they start revising.

Start with the official exam guide and note the domain weightings. Then take a short diagnostic to see where you already stand. Build a plan that spends most of your time on the domains where you are weakest and where the weighting is highest, and book the exam early enough that the date creates real momentum.

Use three signals together: the published domain weightings, the number of objectives inside each domain, and your own diagnostic results. A domain with a large weighting and many objectives deserves the most hours. If a vendor lists prerequisites or recommended experience, treat those areas as assumed knowledge.

Work backwards from the exam date and divide the remaining weeks into concept weeks, lab weeks and review weeks. Keep sessions short and consistent, schedule a weekly recap, and leave the final three days light. Write the plan down where you will see it daily, and adjust it when a domain takes longer than expected.

Yes. Practice questions are a measurement tool, and measuring before you have studied gives you noise rather than signal. Learn a domain first, then use questions on that domain to find gaps. Late in preparation, switch to mixed timed sets so you practise switching context between topics.

Narrow the topic until it is small enough to fix in one session. Read the official documentation for that single feature, build it in a lab, then teach it back in your own words. Keep the failed questions in an error log and retest yourself on that topic after a few days rather than immediately.

Documentation gives you the exact behaviour, defaults, limits and supported configurations that exams are written against. Reading it also trains you to recognise the precise wording a question will use. Where a summary and the documentation disagree, trust the documentation.

Stop adding new material. Review your error log, reference sheets and any diagrams you drew. Do one short timed set two days out to stay sharp, then rest. Confirm the exam location or online proctoring requirements, test your equipment if the exam is remote, and protect your sleep the night before.

Quality varies widely and nothing published by a third party replaces the vendor exam guide. Check who maintains the material, when it was last updated against the current exam version, and whether explanations justify their answers. Be aware that many certification programs prohibit the use of actual exam content, and violations can affect your certification status.
