Campus Layer 2 Infrastructure Design

Question 1 of 30

Time left: 00:00

A campus network currently has a single large Layer 2 domain spanning several access switches. Users occasionally report intermittent outages after access switch maintenance, and packet captures show bursts of broadcast and unknown-unicast flooding during topology changes. Which design change best reduces STP complexity and instability while preserving campus scalability?

Select one option.

Extend the same VLANs across all access switches so that users can move freely without IP address changes
Increase the STP bridge priority of every access switch so that no access switch becomes root
Use a routed access design or restrict VLANs to the access switch pair where they are required
Disable STP on all user-facing ports because edge ports do not normally create loops
Convert all access ports to trunk ports and allow only required VLANs
