What should be checked if a branch router is dropping large numbers of packets?

• A. Check if the switch is configured correctly
• B. Check the routing table for a missing static route
• C. Check the speed and duplex settings
• D. Check the interface description

Answer: (B)

When a branch router is dropping large numbers of packets, a critical area to examine is the routing table for any missing static routes. This is vital because static routes direct the router on how to reach specific networks. If there is a missing static route, packets bound for certain destinations may not have a valid path to follow, which can lead to them being dropped. This situation creates a breakdown in communication, impacting network performance and connectivity. On the other hand, while checking switch configuration is important for overall network functionality, it may not directly pinpoint packet loss specifically at the router level. The speed and duplex settings can affect link integrity and performance, but issues in these areas are typically characterized by errors or dropped packets rather than a systematic failure to route packets to a destination. Lastly, although interface descriptions can be helpful for documentation and management purposes, they do not influence the operational handling of packets. Thus, focusing on static routes provides the most direct insight into the routing issues causing dropped packets.
