Establishing a virtual connection is virtually equivalent to

  • A.connecting as virtual memory
  • B.physically connecting a DTE and DCE
  • C.placing a telephone call prior to a conversion
  • D.placing a modem prior to a conversion

Answer: C

Correct answer: placing a telephone call prior to a conversion

A virtual circuit is set up before any data flows and torn down afterwards, so the route is fixed for the duration - exactly as dialling establishes a path before the conversation begins. Nothing is physically switched into place, which is what makes the circuit virtual.
