Your users are experiencing delay issues while using their main application that requires
connections to remote hosts. You run the command uptime and get the flowing output:
1:07am up 346 day(s), 12:03, 4 users, load average: 0.02, 0.02, 0.01
Which command will be useful in your next step of troubleshooting?
A.
ipadm
B.
traceroute
C.
dladm
D.
snoop
E.
arp
Explanation:
Test the remote connection with traceroute.
The Internet is a large and complex aggregation of network hardware, con-nected together by gateways. Tracking the route one’s packets follow (or
finding the miscreant gateway that’s discarding your packets) can be dif-ficult. traceroute utilizes the IP protocol `time to live’ field and
attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along
the path to some host.
This program attempts to trace the route an IP packet would follow to
some internet host by launching UDP probe packets with a small ttl (time
to live) then listening for an ICMP “time exceeded” reply from a gateway.
Reference: man traceroute
Maybe answer D?
Snoop is more effective to capture filtered network traffic (for specified port, which could be used by application) and inspect for any issues.
B – traceroute will check route taken by packets and report on any excessive time hops
