Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Accessing the instance via Object Storage pre-authenticated requests
Why it's wrong here
Object Storage PARs are for storage objects, not interactive terminal sessions.
- ✓
OCI Bastion Service
Why this is correct
OCI Bastion provides secure, zero-public-IP access to private instances.
- ✓
A bastion host (jump server) deployed in a public subnet with SSH tunneling
Why this is correct
Bastion hosts allow SSH port forwarding to private instances.
- ✗
Changing the instance subnet to public temporarily while debugging
Why it's wrong here
Changing subnets or attaching public IPs violates private security best practices.
- ✗
Direct RDP or SSH over the Internet Gateway without any intermediate host
Why it's wrong here
Private instances lack public IPs and cannot be reached directly via Internet Gateways.
