Correct answer & explanation
✓
TCP port 443 and TCP port 8443.
vSphere Trust Authority components communicate securely over specific ports. The Attestation Service communicates with ESXi hosts and other trust components typically over TCP port 443 (HTTPS) and port 8443 or specific vTA service ports depending on the exact architecture.
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 22 and TCP port 80.
Why it's wrong here
Port 22 is SSH and port 80 is HTTP, neither of which are secure endpoints for Trust Authority.
- ✗
TCP port 902 and UDP port 902.
Why it's wrong here
Port 902 is used for vCenter-to-ESXi heartbeat and host agent communication (UDP/TCP).
- ✓
TCP port 443 and TCP port 8443.
Why this is correct
vSphere Trust Authority services rely on HTTPS (443) and specific management ports like 8443 for key and attestation traffic.
- ✗
UDP port 514 and UDP port 123.
Why it's wrong here
These are standard ports for Syslog (514) and NTP (123).
