Plan: assess workload types, dependencies, and downtime needs

Clean up source datastore

Execute cutover directly

Launch compute in the OCI region

NO.31 Which OCI database option supports globally distributed workloads?

Data Guard only

Globally Distributed Autonomous Database

Classic RAC

NO.32 Redis KEYS command crashes cluster during production use. What should you do instead?

Use KEYS with pattern

Run KEYS on a replica

Increase timeout on KEYS

Use SCAN command iteratively

NO.33 A high-concurrency OLTP workload requires extremely low latency and manual tuning. What’s ideal?

Exadata Cloud Service

Autonomous Transaction Processing (Shared)

Bare Metal VM DB

Autonomous DB Dedicated on Exadata

NO.34 What benefit does API_first design bring with API Gateway in OCI?

No backend needed

Auto_secures traffic

Promotes early client integration and stable contract via OpenAPI spec

Forces minimal API versions

NO.35 Your AI workload in GCP uses Vertex AI and Oracle Autonomous DB. Latency spikes are affecting performance. What’s the best fix?

Use egress-enabled VPN

Add caching layer in GCP

Use Oracle Cross_Cloud Interconnect

Increase local CPU only

NO.36 In a zero-trust microservices architecture on OCI, which combination should you implement?

Network Security Groups between all tiers

Mutual TLS between microservices

Internet Gateway in each subnet

Service Gateway for internal traffic

NO.37 What OCI design practice minimizes impact of a single availability domain (AD) failure?

Use only local backups

Deploy all compute in one AD

Rely on Fault Domains only

Use multiple ADs with redundant resources

NO.38 As part of your organization’s initiative to migrate on-premises workloads to Oracle Cloud Infrastructure using Oracle Cloud Migrations (OCM) service, you have been tasked to understand the end-to-end migration workflow.
Which sequence correctly represents the stages in the OCM migration workflow?
Response:

Assessment and Planning, Discovery, Inventory, Replication, Execution

Discovery, Inventory, Assessment and Planning, Replication, Execution

Inventory, Discovery, Replication, Assessment and Planning, Execution

Discovery, Assessment and Planning, Inventory, Execution, Replication

Assessment and Planning, Replication, Discovery, Inventory, Execution

NO.39 Which tool offers deep SQL_level diagnostics for Oracle databases in OCI?

OCI Monitoring Metrics

Logging Analytics

APM

Database Management + Operations Insights

NO.40 GoldenGate replication is lagging under high DML load. What optimization should you apply first?

Increase network bandwidth only

Use single-threaded extract

Increase source DB CPU allocation

Offload extract and replication to a GoldenGate microservices hub near the source

NO.41 Large plan runs slowly on thousands of resources. What helps?

Copy config to separate project

Upgrade Terraform only

Break config into environment-specific modules

Use -target to focus on specific resources

NO.42 Your enterprise app must recover from a region-wide failure within 15 minutes with minimal data loss. Best solution?

Warm standby with Full Stack DR orchestration

Active-passive replication only

Pilot light with automated recovery

Cold backups + restore

NO.43 You need per-route rate limiting and authentication for functions behind the gateway. Choose approaches.

Add custom authorizer functions for auth

Handle auth in backend function only

Store tokens in function code

Configure API Gateway rate-limiting policies

NO.44 Select all best practices for secure, reusable IaC in OCI.

Write separate configs per environment

Use Terraform modules for reuse

Skip state versioning

Enable state locking on Resource Manager

NO.45 You experience slow terraform plan due to many unused resources. How reduce plan time?

Remove default VCN resource blocks

Split configs into modules per environment

Use targeted -target for specific resources

Decrease Terraform version

NO.46 Select all valid benefits of Google-Oracle interconnect architecture.

Bidirectional private network traffic

Eliminates cross-cloud egress costs

Low-latency cross-cloud communication

Supports public internet fallback

NO.47 Which retry/resilience feature should be enabled for apps connecting to ATP via OCI SDK?

Transparent application failover retries

Keep-alive only

Exponential backoff

Circuit breaker

NO.48 During scaling, your Terraform plan includes adding a Block Volume. What is the correct method?

Create volume manually then import

Add resource and apply; Terraform attaches

Use CLI only

Use local executor from compute

NO.49 You need to deploy a microservice to both OKE and compute instances. Which pipeline design meets OCI best practices?

Use Jenkins with webhook; bypass OCI DevOps

One pipeline but compute deploy only, manual for OKE

Two independent pipelines sharing no components

Separate deployment stages within same pipeline, targeting both endpoints

NO.50 What comprises the physical architecture of Oracle Database@Azure?
Response:

Oracle places three of the OCI availability domains, one in each of the three Azure availability zones.

Oracle creates an OCI pod that is closest to the Azure Data Center and connects it with the nearest OCI region by a low-latency Oracle-managed network link.

OCI pods in Azure Data Center contain the Exadata Database Service stack, but all the other dependencies and controls reside in the nearest OCI data center.

OCI pods that are created inside Azure Data Center are an extension of the OCI data center that have the same OCI infrastructure and service stack, the Exadata Database Service, along with all dependencies.
