VCP-DCV vSphere Performance and Scaling Practice Question
Exhibit
Refer to the exhibit. esxcli network ip connection list | grep 443 tcp 0 0 192.168.10.10:443 192.168.10.20:54321 ESTABLISHED 131230 tcp 0 0 192.168.10.10:443 192.168.10.21:54322 ESTABLISHED 131231 tcp 0 0 192.168.10.10:443 192.168.10.22:54323 TIME_WAIT 0 tcp 0 0 192.168.10.10:443 192.168.10.23:54324 ESTABLISHED 131232
Refer to the exhibit. An administrator runs the command on an ESXi host to check HTTPS connections. The host is running vCenter Server and several VMs. What is the most likely cause of the TIME_WAIT connection?
⚠ Common exam trap
The trap here is that candidates often associate TIME_WAIT with a network or host problem, when in fact it is a standard TCP state indicating a clean connection closure initiated by the remote client.
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
✓
A client closed the HTTPS connection and the host is in TIME_WAIT state.
The TIME_WAIT state is a normal part of TCP connection termination. When a client closes an HTTPS connection, the ESXi host (as the server) enters TIME_WAIT to ensure any delayed segments are not misinterpreted by a new connection. This state is expected and not indicative of a problem.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A firewall is blocking return traffic from that client.
Why it's wrong here
Blocking would not result in TIME_WAIT; the host would not see the connection.
- ✗
The host's TCP stack is misconfigured for high traffic.
Why it's wrong here
TIME_WAIT is a standard TCP state.
- ✗
The host is under memory pressure and dropping connections.
Why it's wrong here
Memory pressure would not show as TIME_WAIT.
- ✓
A client closed the HTTPS connection and the host is in TIME_WAIT state.
Why this is correct
TIME_WAIT is normal after a client disconnects.
