Before upgrading from vCenter 4.x to 5.x, an administrator runs the vCenter Host Agent PreUpgrade Checker. The Checker reports an issue.
What would cause the vCenter Host Agent Pre-Upgrade Checker to report an issue?
A.
The .NET framework 3.5 is installed.
B.
The host network card is only 1 Gbps.
C.
The file system is not intact.
D.
The VMFS file system is version 4.0.
Explanation:
C is correct
The vCenter Host Agent Pre-Upgrade Checker checks to make sure that the agent software is ready to be upgraded. Some of the checks include checking to make sure that the host is reachable, the disk space is sufficient, the network is functioning, the file system is intact, and required patches are applied. Each time you run the tool, the system queries VMware.com and downloads any new updates for the tool. This action ensures that as new upgrade issues are discovered, the tool remains as useful as possible.
