When a design calls for spanning VLANs across a campus network, what are two issues that need to be addressed in the design? (Choose two.)

Spanning VLANs campus-wide relies on STP to prevent loops, and STP convergence events - triggered by any topology change - can cause traffic disruption across the entire extended broadcast domain, making convergence time a critical design concern.

Network accessibility is a general availability concern that applies broadly and is not a specific design challenge uniquely introduced by spanning VLANs across a campus.

When a fault such as a broadcast storm or switching loop occurs in a campus-wide VLAN, the failure propagates to every switch segment where that VLAN exists, severely limiting fault isolation and increasing the blast radius of any single failure.

Application scalability is an application-tier and server-side concern that is not directly caused or constrained by the decision to extend VLANs across a campus network.

User experience is an outcome influenced by many variables and is not a specific network design concern that must be directly addressed when engineering campus-wide VLAN extension.
