Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Dynamic Routing Gateway
Why it's wrong here
A DRG connects VCNs to on-premises networks or other VCNs, but does not manage administrative login sessions.
- ✓
OCI Bastion
Why this is correct
OCI Bastion provides secure, managed, zero-public-IP access to private target resources.
- ✗
NAT Gateway
Why it's wrong here
A NAT Gateway allows internal private instances to initiate outbound connections to the internet, not inbound administrative access.
- ✗
Site-to-Site VPN
Why it's wrong here
While a VPN provides private connectivity, it connects an entire corporate network rather than providing on-demand administrator access.
