Free CompTIA Network+ N10-008 Practice Question

A network administrator notices that a client device is able to communicate with some, but not all devices on the local network. The client device has an IP address of 192.168.1.20. The administrator checks the configuration and finds that the subnet mask is set to 255.255.255.224. What is likely to be the issue the administrator identified?

  • The subnet mask is too broad, causing the device to conflict with another subnet on the network.

  • The client device should be using a subnet mask of 255.255.255.0 to communicate on the local network segment.

  • The client device is on a different subnet than some of the other devices due to an incorrect subnet boundary based on the mask provided.

  • The subnet mask is too restrictive, preventing the device from communicating with any device on the network segment.
