Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Outbound TCP port 443 to Palo Alto Networks XSIAM cloud FQDNs
Why this is correct
Agents communicate exclusively outbound over HTTPS (port 443) to the assigned tenant and service FQDNs.
- ✗
Inbound TCP port 22 and 3389 for remote diagnostics
Why it's wrong here
Cortex XDR agents do not require inbound listening ports for normal cloud orchestration and telemetry reporting.
- ✗
Outbound UDP port 514 for direct syslog streaming to the cloud
Why it's wrong here
Agents do not send syslog data directly via UDP 514; telemetry is transmitted securely over HTTPS.
- ✗
Inbound and outbound TCP port 80 for unencrypted configuration checks
Why it's wrong here
All communication between agents and Cortex XSIAM is strictly encrypted over HTTPS; port 80 is not used.
