2V0-621 Question #112: Real Exam Question with Answer & Explanation

The correct answer is A: The vCenter Server machine is not responding via the network.. The vSphere Web Client SDK connection error can result from the vCenter host being unreachable on the network, an incorrect SSO registration, or an SSL certificate mismatch with the server FQDN.

Question

When attempting to connect to a vCenter Server, an administrator observes the following at the top of the vSphere Web Client: Could not connect to one or more vCenter Server Systems:https://vCenter.corp.com:443/sdk What three reasons could be preventing the vSphere Web Client from communicating with this vCenter Server? (Choose three.)

Options

  • AThe vCenter Server machine is not responding via the network.
  • BAn incorrect entry for this vCenter Server exists in the Single Sign-On service.
  • CThe SSL certificates do not match the FQDN address for the server.
  • DThe Platform Services Controller is external to this vCenter Server.
  • EThe DNS entry for the vCenter Server is incorrect.

Explanation

The vSphere Web Client SDK connection error can result from the vCenter host being unreachable on the network, an incorrect SSO registration, or an SSL certificate mismatch with the server FQDN.

Common mistakes.

  • D. An external PSC is a fully supported deployment topology in vSphere 6.x; its presence alone does not prevent the Web Client from establishing a connection to vCenter Server.
  • E. An incorrect DNS entry would prevent FQDN resolution before any TCP connection is made, producing a name resolution failure rather than the specific SDK endpoint connection error shown.

Concept tested. vCenter Web Client SDK connection failure root causes
