Refer to the exhibit. An administrator notices that the ESXi host is listening on both IPv4 and IPv6 for HTTPS. However, IPv6 traffic is not being forwarded to the host. Which configuration change is most likely needed?

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure a default gateway for the IPv6 stack on the host.
Why this is correct
Without an IPv6 default gateway, traffic cannot be routed to the host.
- ✗
Disable IPv6 and use only IPv4.
Why it's wrong here
The exhibit shows IPv6 is configured and listening; disabling it is not necessary.
- ✗
Remove the IPv4 HTTPS listener to force IPv6.
Why it's wrong here
Removing IPv4 would not resolve the routing issue.
- ✗
Enable IPv6 on the vSphere Distributed Switch.
Why it's wrong here
IPv6 is already listening on the host; the issue is likely at the network layer.
