Users cannot access a webserver and after the traffic is captured. the capture tool shows an ICMP packet that reports "time exceeded in-transit". What is the cause of this webserver access issue?

Question

Options

• AA router along the path is misrouting the packets in a wrong direction.
• BA router along the path has the wrong time.
• CThe server is too far away and the packets require too much time to reach it
• DThe server is too loaded and the connection could not be handled in time

• A
  89% (57)
• B
  3% (2)
• C
  6% (4)
• D
  2% (1)

Explanation

The correct answer is A. The ICMP 'Time Exceeded' message (Type 11, Code 0) is generated when a packet's TTL (Time To Live) field reaches zero before reaching its destination. Each router decrements the TTL by 1; when it hits 0, the router discards the packet and sends this ICMP message back to the source. This typically indicates a routing loop-where routers are forwarding the packet in circles. Answer B is incorrect because TTL has nothing to do with clock time. Answer C is incorrect because geographic distance is irrelevant; TTL is hop-count based. Answer D is incorrect because server load does not cause TTL expiry.
