Service fundamentals review

Which limitations are associated with a traditional Layer 2 switch?

Choose three
  • A Isolates collision domains.
  • B Requires layer 2 loop prevention.
  • C Slow response to topology changes.
  • D Limited to 4094 vlans per switch.
  • E Increased flooding.
Explanation

Traditional Layer 2 designs require loop prevention to avoid bridging loops, and their spanning-tree-based control plane can converge slowly after a topology change. VLAN scalability is also constrained by the 12-bit IEEE 802.1Q VLAN identifier, which supports VLAN IDs 1 through 4094; IDs 0 and 4095 are reserved.
