    Q1. A router receives a packet with a TTL value of 1. What action will the router take?

    • A) Forward the packet
    • B) Drop the packet
    • C) Send an ICMP error message
    • D) Buffer the packet

    Answer: Drop the packet

    Explanation: When a router receives a packet with a TTL (Time To Live) of 1, it decrements the TTL to 0 and then drops the packet because the TTL has expired. It typically sends an ICMP Time Exceeded message back to the source.
