Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configuring database replication (such as Oracle Data Guard) between OCI Autonomous Database and a database running in AWS.
Multicloud DR strategies include active-passive database replication (e.g., Oracle Data Guard between OCI and custom cloud deployments), DNS-based global traffic management (like OCI Traffic Management Steering), and cloud-to-cloud VPN/interconnect backup links.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configuring database replication (such as Oracle Data Guard) between OCI Autonomous Database and a database running in AWS.
Why this is correct
Database-level replication ensures data synchronization for DR across clouds.
- ✓
Using OCI Traffic Management Steering to fail over DNS traffic between OCI and AWS endpoints based on health checks.
Why this is correct
DNS traffic steering handles global application-level failover between clouds.
- ✗
Physically merging AWS VPC physical switches into OCI Meet-Me-Rooms.
Why it's wrong here
You cannot physically merge hardware switches across cloud provider datacenters.
- ✗
Replicating OCI IAM identity domains natively inside AWS IAM without federation.
Why it's wrong here
OCI IAM domains and AWS IAM are separate identity systems and cannot be natively replicated without federation.
- ✓
Establishing redundant IPsec VPN tunnels between OCI DRG and AWS VGW for secure private connectivity.
Why this is correct
Secure private cross-cloud links are essential for database synchronization and replication traffic.
