SNCF — Securing Networks with Firepower — Question 308

An engineer must build redundancy into the network and traffic must continuously flow if a redundant switch in front of the firewall goes down. What must be configured to accomplish this task?

Answer options

• A. redundant interfaces on the firewall cluster mode and switches
• B. redundant interfaces on the firewall noncluster mode and switches
• C. vPC on the switches to the interface mode on the firewall cluster
• D. vPC on the switches to the span EtherChannel on the firewall cluster

Correct answer: D

Explanation

Answer D is correct because configuring vPC on the switches to the span EtherChannel on the firewall cluster ensures that traffic can continue to flow even if one switch fails. The other options do not provide the same level of redundancy or failover capabilities needed for continuous traffic flow.
