Well as most exams like you to memorise numbers I thought I’d put together this list of ports that are used within ESX, all of the ports here can be found in the firewall config in the Security Profile Configuration page on the host/virtual center.

Incoming connections

CIM Secure Server 5989 TCP

Outgoing

Licence Server 27000 27010 TCP

CIM SLP 427 UDP TCP Incoming and outgoing

AAM 2050-2250,8042-8045 Incoming and outgoing

Virtual Center Agent 902 UDP

Iscsi Client 3260 TCP

NTP Client 123 UDP

SSH 22 TCP Incoming and outgoing

VCB 443,902 TCP

Alot of these ports I’m sure you’ve all seen before its just really the vmware specific ports that you need to concerntrate on as I’m sure like most other exams I’ve taken they will want to test you on them.
