Which command displays interface information and packet flow counts?

• A. Displays interface information and packet flow counts
• B. Displays the entire routing table
• C. Displays the startup configuration
• D. Displays the active VPN sessions

Answer: (A)

Monitoring interface status and traffic counters is what this is testing. The command to use is typically show interfaces, which reveals per-interface details such as whether the link is up, speed and duplex, IP/mask, and the packet flow counts (packets in and out, errors, and drops). This makes it the best fit for displaying both interface information and how much traffic is moving through each interface.

The other options point to different views: showing the routing table reveals paths and next-hops, showing the startup configuration shows saved boot-time settings, and showing active VPN sessions lists current VPN connections. None of these provide the per-interface traffic counters, so they don’t meet the requirement.
