7. Question 67 · 610 in bank

   A network engineer configures a new switch and connects it to an existing switch for expansion and redundancy. Users immediately lose connectivity to the network. The network engineer notes the following spanning tree information from both switches.

   

   Which of the following best describes the issue?

   • AThe port cost should not be equal.
   • BThe ports should use link aggregation.
   • CA root bridge needs to be identified.
   • DThe switch should be configured for RSTP.

   Show answer
