-- Exhibit —
Users accessing the WinXP virtual machine shown in the exhibit report intermittent connectivity to the corporate network.
The configuration is as follows:
This virtual machine runs in a DRS/HA cluster of two ESXi hosts.
The VCP_DCV_Example vSphere Distributed Switch was recently created.
The WinXP virtual machine was recently migrated from another vSphere Distributed Switch.
The WinXP virtual machine was able to connect prior to migration to this switch.
No changes to the VCP_DCV_Example switch have been made since creation.
Which step should the administrator take to resolve the WinXP virtual machine’s intermittent connectivity to the corporate network?
A. Add the ESXi host to the switch where the virtual machine is currently running
B. Disable Port Blocking on the VCP_DCV_Example switch
C. Disable Port Blocking on the Production port group
D. Enable Network I/O Control on the switch to better balance I/O
Correct Answer: A
Explanation/Reference:
Explanation:
Because no changes have been made to the VCP_DCV_Example switch since creation, it implies that hosts were not yet added to the switch. Hosts and physical adapters can be added to a vSphere distributed switch at the distributed switch level after it is created. After migrating the virtual machine to the dvSwitch, you should add the associated hosts to the switch as well.
Incorrect Answers:
B: Port blocking policies allow you to selectively block ports from sending or receiving data. Enabling port blocking will not solve the problem.
C: Port blocking policies allow you to selectively block ports from sending or receiving data. Enabling port blocking will not solve the problem.
D: Network resource pools determine the bandwidth that different network traffic types are given on a vSphere distributed switch. This will not solve the connectivity issue.
