Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
TCP port 443 for cloud tenant and agent communication
Broker VMs ingest syslog over standard ports (such as UDP/TCP 514 or custom ports) and communicate with agents/cloud over TCP 443.
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 port 443 for cloud tenant and agent communication
Why this is correct
TCP port 443 is used for secure TLS communication between agents, Broker VMs, and the Cortex XDR cloud.
- ✓
UDP/TCP port 514 (or configured custom ports) for Syslog log collection
Why this is correct
Syslog log collectors on the Broker VM listen on standard ports like UDP/TCP 514 or custom designated ports.
- ✗
TCP port 23 for Telnet remote management
Why it's wrong here
Telnet is insecure and disabled by default; management is conducted via SSH.
- ✗
UDP port 69 for Trivial File Transfer Protocol (TFTP) agent staging
Why it's wrong here
TFTP is not used for Cortex XDR agent staging.
- ✗
TCP port 3389 for Remote Desktop Protocol (RDP) log streaming
Why it's wrong here
RDP is used for remote desktop sessions, not Broker VM log streaming.
