Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A direct physical connection between the load balancer and on-premises switches
Why it's wrong here
Load balancers operate within VCN subnets and interface with backend servers via IP, not direct physical switch connections.
- ✗
Manual IP routing table hacks on every backend compute node
Why it's wrong here
Load balancers route traffic natively without manual routing hacks on backends.
- ✓
SSL/TLS certificates attached to HTTPS listeners if terminating secure traffic
Why this is correct
HTTPS listeners require SSL certificates for secure client connections.
- ✓
Backend sets with defined health checks to monitor backend instance responsiveness
Why this is correct
Health checks ensure traffic is only routed to healthy backend servers.
- ✓
Listeners configured with appropriate port and protocol (e.g., HTTP or HTTPS)
Why this is correct
Listeners check for incoming client traffic on specified ports.
