Question 320
At West Auditorium, a template changed VLAN-instance map on half the distribution switches. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.
Explanation
Correct Answers
This is the continuing risk-control element for West Auditorium. Version-control MST mappings and stage broad region changes prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.
This is the implementation element for the West Auditorium case: MSTP maps VLANs to spanning-tree instances inside a consistent region. The specific action Align MST region name revision and mapped VLAN sets on intended peers addresses the stated fault; the question also requires a persistent risk control.
Incorrect Answers
This may be an ongoing precaution for End-to-end MTU and frames: A path's effective MTU is limited by the smallest supported segment and encapsulation overhead. It does not resolve the MST region matching requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is mSTP maps VLANs to spanning-tree instances inside a consistent region
This may be a configuration step for Voice VLAN LLDP-MED: LLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies. It does not resolve the MST region matching requirement in West Auditorium and is not one of the two controls requested. The direct mechanism here is mSTP maps VLANs to spanning-tree instances inside a consistent region
