OCI 1Z0-1151-25 Sample Questions with Explanations

These original sample questions are designed to help you check how the exam topics appear in decision-style prompts. They are not taken from the live exam.

Use these sample questions as a guided self-assessment for OCI Multicloud Architect Professional (1Z0-1151-25) topics such as identity federation, cross-cloud connectivity, private routing, data locality, replication, shared responsibility, observability, failover, and governance boundaries. The prompts focus on keeping trust, transport, data, and operations boundaries explicit.

1Z0-1151-25 OCI Multicloud sample questions

Work through each prompt before opening the explanation. Multicloud questions usually reward making ownership explicit: identity source, network path, data location, key ownership, observability, recovery, and operating model.

Question 1

Topic: Cross-cloud identity

A company operates workloads in OCI and another cloud. It wants centralized user lifecycle management and fewer long-lived local credentials in each cloud. Which design is strongest?

• A. Create separate unmanaged local administrator accounts for every user in every cloud.
• B. Share one administrator account across both clouds and track use in a spreadsheet.
• C. Copy API keys between clouds so each platform can impersonate the other.
• D. Use federated identity and scoped role mapping so users authenticate through a central identity source and receive only the required permissions in each environment.

Best answer: D

Explanation: Federated identity reduces local credential sprawl and supports centralized lifecycle management. Scoped roles or groups still need to be mapped carefully so authorization remains least privilege in each cloud.

Why the other choices are weaker:

• A duplicates identity lifecycle work and increases stale-account risk.
• B removes individual accountability.
• C spreads long-lived credentials and blurs trust boundaries.

What this tests: Identity federation, role mapping, least privilege, and multicloud credential hygiene.

Question 2

Topic: Private cross-cloud connectivity

A latency-sensitive application in OCI must communicate with a managed database service in another cloud. The design should avoid unpredictable public-internet paths where practical. What is the strongest first design question?

• A. Which private or partner connectivity path, routing model, DNS resolution, and security controls support the required latency and availability?
• B. Which public IP range is easiest for users to memorize?
• C. How can every subnet be made public to simplify troubleshooting?
• D. Which cloud can disable logging to reduce integration noise?

Best answer: A

Explanation: Multicloud connectivity is a transport and control-boundary problem. The design should establish private or partner connectivity where appropriate, then confirm routing, DNS, filtering, monitoring, and failure behavior.

Why the other choices are weaker:

• B optimizes memorability instead of architecture.
• C expands exposure.
• D removes the evidence needed to operate the connection.

What this tests: Cross-cloud network path design, private connectivity, DNS, routing, and security controls.

Question 3

Topic: Data locality and egress

An analytics workload runs in OCI, but the source data is generated in another cloud. The workload reads large datasets repeatedly, and egress cost and latency are becoming significant. What should the architect evaluate first?

• A. Whether all logs can be deleted to reduce storage.
• B. Whether users can download the data manually when needed.
• C. Whether to move compute closer to the data, replicate curated data into OCI, cache data intentionally, or redesign the pipeline based on cost, latency, governance, and freshness requirements.
• D. Whether to use only public internet transfer because it is always cheapest.

Best answer: C

Explanation: Data locality questions require balancing compute placement, replication, caching, freshness, cost, and governance. Repeated large cross-cloud reads often indicate that the data boundary or compute location needs redesign.

Why the other choices are weaker:

• A addresses logs, not the source-data movement problem.
• B turns a pipeline into a manual process.
• D overstates public internet suitability and ignores cost, latency, and control requirements.

What this tests: Data locality, egress trade-offs, replication, cache strategy, and workload placement.

Question 4

Topic: Cross-cloud recovery

A multicloud architecture replicates data from one provider to another. Leadership asks whether the business can fail over during a regional outage. What should the architect emphasize?

• A. Replication alone proves recovery because data exists in two places.
• B. A tested failover plan that covers application behavior, identity, DNS, network paths, data consistency, observability, rollback, and ownership.
• C. A diagram showing both cloud logos.
• D. A larger primary-region database shape.

Best answer: B

Explanation: Recovery is not proven by replication alone. The business needs tested application cutover, access, routing, data consistency checks, monitoring, rollback criteria, and clear ownership during the incident.

Why the other choices are weaker:

• A ignores application and operational recovery.
• C is documentation, not a tested plan.
• D may improve primary capacity but does not prove cross-cloud failover.

What this tests: Multicloud DR, failover validation, recovery ownership, and operational readiness.
