10 of 338+ questions
Question #1 - Application Design on IBM Cloud
A claims-intake service at Bluebell Insurance handles large bursts when severe weather events occur and near-zero traffic overnight. It must decompose into services that scale independently.
Which decomposition best fits the traffic pattern and responsibility separation?
A) A single monolith that scales by adding replicas
B) Separate microservices for intake, validation, enrichment, and notification, communicating via Event Streams topics
C) One microservice per customer so each can be scaled separately
D) A shared stored procedure in the claims database
Show solution
Correct answers: B – Explanation:
Splitting by business capability and communicating through Event Streams gives each microservice independent scaling and fault isolation — the canonical IBM Cloud microservice-plus-events pattern. A monolith cannot scale parts independently. Per-customer services explode operational surface area. Stored procedures couple logic to one database and defeat the scaling goal. Source: Check Source
Question #2 - Application Design on IBM Cloud
A loyalty API at Aspenwood Retail must stay available even when a downstream rewards engine is slow or briefly unavailable.
Which resilience pattern is most appropriate for the loyalty API?
A) Wrap the rewards engine call in a circuit breaker with a fallback that serves cached loyalty totals
B) Retry indefinitely until the rewards engine responds
C) Fail the loyalty request whenever the rewards engine is slow
D) Call the rewards engine from the browser so the API never depends on it
Show solution
Correct answers: A – Explanation:
A circuit breaker with a cached fallback lets the loyalty API degrade gracefully while protecting both services from cascading load — the canonical resilience pattern for slow downstream dependencies. Indefinite retries amplify load and extend outages. Hard-failing the loyalty call propagates every downstream blip to the customer. Calling from the browser exposes keys and breaks API contract boundaries. Source: Check Source
Question #3 - Application Design on IBM Cloud
Starfield Finance needs to expose a rates API to twelve partner banks with differing rate limits, OAuth scopes, and analytics needs.
Which IBM Cloud capability is designed for this multi-consumer exposure pattern?
A) IBM API Connect with partner-specific products, plans, and OAuth-secured APIs
B) A single unsecured REST endpoint with per-partner IP allowlisting in a spreadsheet
C) One separately deployed instance of the API per partner
D) Direct database access granted to each partner
Show solution
Correct answers: A – Explanation:
API Connect models products, plans, and OAuth per consumer and is IBM’s stated answer for differentiated multi-partner API exposure. IP allowlists cannot enforce scope or per-plan limits and are error-prone. Per-partner instances multiply cost and deploys with no offsetting benefit. Direct DB access collapses the contract boundary entirely. Source: Check Source
Question #4 - Programming and Integration
An inventory microservice at Windham Pharma needs to publish an event every time a stock level crosses a reorder threshold, with at-least-once delivery and consumer replayability.
Which IBM Cloud service best fits the requirement?
A) Email alerts to the operations distribution list
B) IBM Event Streams, using Kafka topics that the service publishes to and consumers subscribe to with retained offsets
C) A shared MySQL table polled by every consumer
D) Direct HTTP calls from the microservice to each known consumer
Show solution
Correct answers: B – Explanation:
IBM Event Streams (Kafka) provides at-least-once delivery and consumer offsets that enable replay — its canonical pattern. Email is not a durable event bus. Polling a shared table gives weak delivery semantics and couples consumers tightly. Direct HTTP fan-out requires the producer to know every consumer and loses replay. Source: Check Source
Question #5 - Programming and Integration
A receipts pipeline at Juniper Markets runs a short function per receipt and currently costs a fortune because the team leaves a container pool running 24/7 even though the workload is bursty.
Which IBM Cloud capability matches this workload pattern?
A) A dedicated bare-metal server with the function running on cron
B) A permanent Kubernetes Deployment scaled manually
C) IBM Cloud Code Engine (or Functions) running the receipt handler as an event-driven function that scales to zero between bursts
D) An always-on VSI that polls every minute
Show solution
Correct answers: C – Explanation:
Serverless functions on IBM Cloud scale to zero between bursts, which is the canonical match for short, spiky per-event workloads. A permanent Deployment pays for idle capacity. Bare metal adds the most overhead for the least flexibility. A polling VSI still pays continuously. Source: Check Source
Question #6 - Power Virtual Server Interop
A modernization team at Ashford Bank is moving a customer-facing web app to IBM Cloud while keeping its core-banking engine on AIX in IBM Power Virtual Server. Transactions must remain reliable across the boundary.
Which integration pattern is most appropriate?
A) Direct JDBC calls from the web app to the AIX database over the public internet
B) Nightly flat-file exports from AIX to object storage
C) Screen-scraping the green-screen terminal from the web app
D) IBM MQ between the web app and the AIX application over VPC peering to the Power workspace, with transactional message delivery
Show solution
Correct answers: D – Explanation:
IBM MQ with transactional delivery over private connectivity to the Power workspace is IBM’s canonical integration pattern between cloud-native apps and AIX systems of record. Public-internet JDBC exposes a database port and violates standard security posture. Screen-scraping is brittle and undocumented as an integration channel. Nightly exports cannot meet real-time transaction requirements. Source: Check Source
Question #7 - Power Virtual Server Interop
Clearcrest Mortgage needs a private network path from a new OpenShift cluster on IBM Cloud to an existing IBM i workload on Power Virtual Server.
Which connectivity design satisfies the private-network and cross-service requirement?
A) Open the IBM i host to public internet and allowlist the cluster’s public IPs
B) Peer the OpenShift VPC to the Power Virtual Server workspace via Transit Gateway so both networks communicate privately
C) Tunnel all traffic through an operator’s laptop with SSH port forwarding
D) Rehost the IBM i workload in the OpenShift cluster as a container
Show solution
Correct answers: B – Explanation:
Transit Gateway connecting a VPC to a Power Virtual Server workspace is the supported pattern for private cloud-to-Power connectivity. Public exposure defeats the private-network requirement. SSH port forwarding through a laptop is not a production data path. IBM i cannot be meaningfully containerized inside OpenShift. Source: Check Source
Question #8 - DevOps and Release Practice
A pricing microservice at Elmfield Telecom is currently deployed by a Jenkins job that a senior engineer triggers manually. Leadership wants auditable, automated releases from commit to production.
Which IBM Cloud capability meets the requirement?
A) Keep Jenkins manual so the senior engineer stays accountable
B) Let each developer deploy from their laptop
C) Disable releases entirely until the team writes a proposal
D) IBM Cloud Continuous Delivery with Tekton pipelines defined in Git, triggered on commit and producing evidence artifacts for each promotion
Show solution
Correct answers: D – Explanation:
IBM Cloud Continuous Delivery with Tekton pipelines is the canonical answer for commit-to-prod automation with evidence. Manual Jenkins triggers are the problem, not the solution. A release freeze is not a delivery capability. Laptop deploys fail every audit control. Source: Check Source
Question #9 - DevOps and Release Practice
Northridge Travel’s Tekton pipeline currently pushes container images without recording which source commit they were built from, and auditors are asking how to prove provenance.
Which change addresses the audit request?
A) Sign images with the build commit SHA and publish evidence artifacts (build logs, SBOM, digest) to the Evidence Locker as part of the Tekton pipeline
B) Let auditors trust the build engineer’s word
C) Add a comment to the image description field manually after each build
D) Stop building images in CI and only build them on developer laptops
Show solution
Correct answers: A – Explanation:
Signed images plus evidence artifacts recorded in the Evidence Locker is the IBM Cloud DevSecOps pattern for build provenance. Auditor trust without evidence is not a control. Manual comments can be altered and are not cryptographically linked to the build. Laptop builds destroy the audit trail entirely. Source: Check Source
Question #10 - Security and Identity
Vespera Health’s microservices on IBM Cloud need to call other IBM Cloud services without long-lived API keys embedded in configuration.
Which IBM Cloud identity capability addresses the requirement?
A) Store a shared admin API key in the deployment descriptor
B) Pass the CTO’s personal API key to each service
C) Use IAM Trusted Profiles so workloads assume a profile with scoped access at runtime
D) Disable IAM and use open network rules
Show solution
Correct answers: C – Explanation:
IAM Trusted Profiles let workloads assume scoped identities at runtime, removing long-lived keys from configuration. Shared admin keys are the anti-pattern this is intended to replace. Using a personal key is both insecure and traceable only to the human. Disabling IAM removes all access control. Source: Check Source
