A network administrator is assisting a user who is unable to access network services by using hostname on Host 1. Another user in the same office is able to access the network services with no issue on Host 2. The network administrator runs a command on the affected machine and the working machine and compares the following output:
Which of the follow should the network administrator change to restore connectivity?
The issue at hand is with the hostname resolution on Host 1. Hostname resolution is handled by the DNS server. In this case, Host 1 is configured with the DNS server IP as 192.168.1.53, whereas Host 2, which is not facing the issue, is configured with DNS server IP 192.168.0.53. To restore connectivity and proper hostname resolution on Host 1, updating the DNS server on Host 1 to match the DNS server IP on Host 2, which is 192.168.0.53, should resolve the issue.
It can still reach 192.168.1.53 since they are on the same network.. I am unsure why the answer is D
It's because it is unable to reach by the hostname, and DNS is what converts IP to hostnames. D is correct here, I hope this helps.
This question is rediculous, I agree with you that it should be able to reach the dns on 1.53 because they are both on the same subnet, according to the subnet mask. None of these answers are correct. The only thing I can see is that they want you to know that dns converts the hostname to ip, and want you to think about dns. Its the LEAST wrong answer. still stupid.
It's a called a "red herring" .. mean misleading questions. Almost seems like Comptia wants customers to fail the exam to pay another 350 bucks to retake it.
Correction was not included with my post: Forgot to type the beginning of the range. Valid Usable Device IPs: 192.168.0.1 - 192.168.1.254
Nothing wrong with the question. Valid IP range with 255.255.254.0 "/23" subnet mask Subnet IP: 192.168.0.0 Valid Usable Device IPs: 192.168.1.254 Broadcast IP: 192.168.1.255 Since Host1, Host2, Default Gateway, DNS servers all have configured an IP that is in the above valid range, Answers A,B,C are unnecessary. Host1 can communicate. Host2 cannot. Troubleshooting 101, don't overlook the easy and obvious. Host1 and Host2 are statically configured and someone "fat-fingered" Gateway IP on Host1. People in the discussion mentioned that Host1 would still be able to query a DNS server at 192.168.1.53, which is true. Your DNS server does not have to be on the same IP subnet as a device anyway. In this network there is only 1 DNS server, and its IP is 192.168.0.53.
Probably the creator of this dump badly formulated the question that was on the exam
D. Update the DNS server on Host 1 to 192.168.0.53.
D makes the most sense. Host 1 is the issue, so making changes to host 2 doesn't make any sense since other users can connect to it just fine Clueing into hostname indicates a DNS issue and changing it to match the DNS on host 2 should fix it
