  • 172.16.0.1 255.255.240.0
  • 172.16.20.1 255.255.254.0
  • 172.16.18.255 255.255.252.0
Q.3

If an Ethernet port on a router were assigned an IP address of 172.16.112.1/25, what would be the valid subnet address of this host?

  • 172.16.112.0
  • 172.16.0.0
  • 172.16.96.0

Q.4

Which two statements describe the IP address 10.16.3.65/23?

  1. The subnet address is 10.16.3.0 255.255.254.
  2. The lowest host address in the subnet is 10.16.2.1 255.255.254.
  3. The last valid host address in the subnet is 10.16.2.254 255.255.254.
  4. The broadcast address of the subnet is 10.16.3.255 255.255.254.
  • 1 and 3
  • 2 and 4
  • 1, 2 and 4
  • 2, 3 and 4
Q.5

Using the illustration from the previous question, what would be the IP address of S0 if you were using the first subnet? The network ID is 192.168.10.0/28 and you need to use the last available IP address in the range. Again, the zero subnet should not be considered valid for this question.

  • /27
  • /28
  • /29
  • /30
Q.8

You have an interface on a router with the IP address of 192.168.192.10/Including the router interface, how many hosts can have IP addresses on the LAN attached to the router interface?

  • 6
  • 8
  • 30
  • 32
Q.9

  • 14
  • 15
  • 16
  • 30
Q.10

  • 172.16.36.0
  • 172.16.48.0
  • 172.16.64.0
  • 172.16.0.0
Q.12

  • 7 subnets, 30 hosts each
  • 8 subnets, 8,190 hosts each
  • 8 subnets, 2,046 hosts each
  • 7 subnets, 2,046 hosts each
