Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
TCP ports 22, 80, and 443
Why it's wrong here
Port 22 (SSH) is not used for agent-to-cloud communications.
- ✓
TCP port 443
Why this is correct
Cortex XDR agents communicate exclusively over outbound TCP port 443 using TLS.
- ✗
UDP port 514 and TCP port 6514
Why it's wrong here
These ports are used for Syslog forwarding, not standard Cortex XDR agent telemetry.
- ✗
TCP port 80 and 443
Why it's wrong here
Port 80 is insecure and not used for Cortex XDR cloud communications.
