Q

A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in its ARP cache. How will the device obtain a destination MAC address?

It will send the frame and use its own MAC address as the destination.
It will send the frame with a broadcast MAC address.
It will send an ARP request for the MAC address of the destination device.
It will send a request to the DNS server for the destination MAC address.
It will send an ARP request for the MAC address of the default gateway.

A

It will send an ARP request for the MAC address of the default gateway.

Q

A network administrator wants to have the same network mask for all networks at a particular small site. The site has the following networks and number of devices:

IP phones – 22 addresses
PCs – 20 addresses needed
Printers – 2 addresses needed
Scanners – 2 addresses needed

The network administrator has deemed that 192.168.10.0/24 is to be the network used at this site. Which single subnet mask would make the most efficient use of the available addresses to use for the four subnetworks?

  1. 255.255.240
  2. 255.255.0
  3. 255.255.192
  4. 255.255.224
  5. 255.255.248
  6. 255.255.252
A

255.255.255.224

Q

Refer to the exhibit. The network administrator has assigned the LAN of LBMISS an address range of 192.168.10.0. This address range has been subnetted using a /29 prefix. In order to accommodate a new building, the technician has decided to use the fifth subnet for configuring the new network (subnet zero is the first subnet). By company policies, the router interface is always assigned the first usable host address and the workgroup server is given the last usable host address. Which configuration should be entered into the properties of the workgroup server to allow connectivity to the Internet?

IP address: 192.168.10.38 subnet mask: 255.255.255.248, default gateway: 192.168.10.33
IP address: 192.168.10.38 subnet mask: 255.255.255.240, default gateway: 192.168.10.33
IP address: 192.168.10.254 subnet mask: 255.255.255.0, default gateway: 192.168.10.1
IP address: 192.168.10.41 subnet mask: 255.255.255.248, default gateway: 192.168.10.46

A

IP address: 192.168.10.38 subnet mask: 255.255.255.248, default gateway: 192.168.10.33
