Which of the following is most accurate with respect to designing high availability within the Enterprise Campus network?

Question

Options

• AHigh availability at and between the Distribution and Access layers is as simple as redundant
• BNon-deterministic traffic patterns require a highly available modular topology design
• CDistribution layer high availability design includes redundant switches and Layer 3 equal-cost load
• DDefault gateway redundancy allows for the failure of a redundant Distribution switch without

• A
  16% (4)
• B
  4% (1)
• C
  8% (2)
• D
  72% (18)

Explanation

Default gateway redundancy (achieved through protocols like HSRP, VRRP, or GLBP) is a critical component of distribution layer high availability. It allows end devices to continue forwarding traffic through a standby distribution switch if the primary fails, without any manual intervention or reconfiguration on the access layer. This is the most accurate and complete statement about HA design at the distribution layer. The other options are either oversimplified (A - redundant links alone are not sufficient), inaccurate (B - deterministic traffic patterns are preferred in HA designs), or incomplete (C - while redundant switches and L3 ECMP are part of the design, they don't cover the full picture of distribution HA including gateway redundancy).
