An administrator is unable to login to vCenter Server when using the vSphere Web Client. The
administrator successfully accessed vCenter Server using the client earlier the same day.
What is the most appropriate first step the administrator should take to resolve this issue?
A.
Verify the web browser being used has Adobe Flash plugin version 11.5 or later
B.
Verify the vCenter Single Sign-On service is running on the vCenter Server
C.
Verify the vSphere Web Server service is running on the vCenter Server
D.
Verify the administrator has permissions configured in vCenter Server
A is the answer. That is the first step and could be the issue if he is using an out dated browser. the fact he logged into vCenter with the client means that B is defiantly not the first thing to check.
It means to me: that had already logged on the same day with the same client used before, that is the web client.
Then, after the SSO service could have stopped.
Answer is B.
Its B. The single sign on service could have been stopped or shutdown unexpectedly. Checking to see if its running is an easy first step
B
