200-301 Question 86
Single answerA network administrator is tasked with configuring a subnet for a new department in an organization. The department requires 50 usable IP addresses. The administrator assigns the network 192.168.10.0/26. After verifying the configuration, the department reports that some devices cannot connect. What is the issue?
- A
The /26 subnet mask does not provide enough IP addresses for the department's needs.
- B
The subnet mask should be changed to /25 to accommodate more hosts.
- C
The network 192.168.10.0/26 provides 62 usable IP addresses, which is sufficient.
- D
There is a configuration error in the devices' default gateway.
Show answer and explanation
Correct answer: C
Explanation
The network 192.168.10.0/26 provides 62 usable IP addresses (64 total addresses minus 2 for the network and broadcast addresses). This is sufficient for the department's requirement of 50 IP addresses. The reported connectivity issue is not related to the subnet size. The administrator should further troubleshoot device configurations or connectivity issues unrelated to IP addressing.
- A. Incorrect.
Incorrect. A /26 subnet mask provides 62 usable IP addresses, which is sufficient for the department's requirement of 50 addresses.
- B. Incorrect.
Incorrect. While a /25 subnet mask provides more IP addresses, the /26 subnet already meets the department's needs. Changing the subnet mask is unnecessary.
- C. Correct.
Correct. A /26 subnet provides 62 usable IP addresses, covering the department's requirement of 50 addresses. The issue reported is not due to the subnet size.
- D. Incorrect.
Incorrect. The question does not indicate any issues with the devices' default gateway configuration.
