GCFA · Question #129
John works as a professional Ethical Hacker. He has been assigned the project of testing the following result: Considering the above traceroute result, which of the following statements can be true?…
The correct answer is A. While tracerouting, John's network connection has become slow. B. Some router along the path is down. C. The We-are-secure server is using a packet filtering firewall. Traceroute timeouts or asterisks at hops can indicate multiple conditions including network slowness, downed routers, or firewall packet filtering blocking ICMP probes.

Why each option
Traceroute timeouts or asterisks at hops can indicate multiple conditions including network slowness, downed routers, or firewall packet filtering blocking ICMP probes.
When a traceroute shows delayed or missing responses, it can indicate that the network connection has become slow, causing probe packets to time out before receiving a reply.
Asterisks or missing hops in a traceroute output often indicate that a router along the path is unreachable or down, preventing ICMP TTL-exceeded messages from returning.
A packet filtering firewall on the destination server can silently drop ICMP or UDP probe packets, causing the final hops to appear as timeouts while earlier hops respond normally.
An invalid IP address would cause the traceroute to fail immediately at the DNS or ARP resolution stage, not produce a partial hop trail with asterisks at specific points.
