Which network security construct must be configured to allow communication between the GoldenGate deployment and the Autonomous Database instance?
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
✓
Configure VCN security lists or Network Security Groups (NSGs) allowing outbound TCP port 1522 and inbound mTLS traffic, and supply the ADB wallet
Autonomous Database requires mTLS connections and specific egress/ingress rules; when using GoldenGate to connect to Autonomous Database, the GoldenGate subnet must allow outbound traffic and connect using the appropriate wallet and port 1522.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure VCN security lists or Network Security Groups (NSGs) allowing outbound TCP port 1522 and inbound mTLS traffic, and supply the ADB wallet
Why this is correct
Correct. Port 1522 is standard for Autonomous Database TCPS/mTLS connections, requiring appropriate NSG rules and the client wallet.
- ✗
Expose an API Gateway with public IP routing directly to the database undo tablespace
Why it's wrong here
Incorrect. API Gateways do not manage direct TNS database connections.
- ✗
Configure a Local Peering Gateway with remote VCN route tables pointing to port 22
Why it's wrong here
Incorrect. Port 22 is for SSH, not database replication traffic.
- ✗
Attach an Internet Gateway directly to the Autonomous Database private IP address
Why it's wrong here
Incorrect. Autonomous Database instances do not attach directly to Internet Gateways; private endpoints or service gateways are used.
