How does traceroute map the route a packet travels from point A to point B?
A. Uses a TCP timestamp packet that will elicit a time exceeded in transit message
B. Manipulates the value of the time to live (TTL) within packet to elicit a time exceeded in
transit message
C. Uses a protocol that will be rejected by gateways on its way to the destination
D. Manipulates the flags within packets to force gateways into generating error messages
Answer: B
Explanation:
Traceroute works by increasing the “time-to-live” value of each successive batch of packets
sent. The first three packets have a time-to-live (TTL) value of one (implying that they make
a single hop). The next three packets have a TTL value of 2,and so on. When a packet
passes through a host,normally the host decrements the TTL value by one,and forwards
the packet to the next host. When a packet with a TTL of one reaches a host,the host
discards the packet and sends an ICMP time exceeded (type 11) packet to the sender. The
traceroute utility uses these returning packets to produce a list of hosts that the packets
have traversed en route to the destination.
