A network engineer must propose a scalable enterprise campus access-distribution design model. Which two scaling factors are the most important to be considered for the Virtual Switching System…

Question

Options

• AVSS stops VLAN spanning to the access switches.
• BBoth VSS nodes are active from control-plane perspective.
• CSTP must be implemented as a loop-avoidance mechanism.
• DVSS eliminates the need to implement FHRP for each VLAN.
• ESTP root and FHRP primary must be tuned at the same node.

• A
  6% (1)
• B
  6% (1)
• C
  78% (14)
• E
  11% (2)

Explanation

VSS (Virtual Switching System) logically combines two physical Cisco Catalyst switches into a single switch. (C) STP must still be implemented as a loop-avoidance mechanism for access ports that are not part of a Multichassis EtherChannel (MEC), since not all links in the campus can be bundled into MEC. (D) Because the VSS pair appears as a single logical device sharing one management IP and one MAC address per SVI, there is no need to configure FHRP (e.g., HSRP/VRRP) on a per-VLAN basis-a major simplification. Option A is false (VSS does not inherently prevent VLAN spanning). Option B is false (one node is VSS Active and controls the control plane; the other is VSS Standby). Option E is irrelevant to VSS scaling.
