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

Security lists or network security groups allowing traffic on port 1522

Private endpoints require a subnet in the VCN, appropriate security rules, and DNS resolution/service gateways or VCN peering if accessing across VCNs.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Security lists or network security groups allowing traffic on port 1522

    Why this is correct

    Autonomous Database uses port 1522 for mTLS / TLS connections.

  • DNS configuration to resolve the private IP address of the database endpoint

    Why this is correct

    Proper DNS setup is required to resolve the database private IP.

  • An Internet Gateway attached to the private subnet

    Why it's wrong here

    Private endpoints do not require or use Internet Gateways.

  • A Public Load Balancer fronting the private IP address

    Why it's wrong here

    Public load balancers are neither required nor used for private endpoint database connectivity.

  • A subnet designated for the Autonomous Database private endpoint

    Why this is correct

    Private endpoints require a dedicated subnet within the VCN.
