- A4
- B6
- C8
- D10
- E12
5Refer to the exhibit. A company uses the address block of 128.107.0.0/16 for its network. What subnet mask would provide the maximum number of equal size subnets while providing enough host addresses for each subnet in the exhibit?
- A255.255.255.0
- B255.255.255.128
- C255.255.255.192

6Refer 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?
- AIP address: 192.168.10.65 subnet mask: 255.255.255.240, default gateway: 192.168.10.76
- BIP address: 192.168.10.38 subnet mask: 255.255.255.240, default gateway: 192.168.10.33
- CIP address: 192.168.10.38 subnet mask: 255.255.255.248, default gateway: 192.168.10.33
- DIP address: 192.168.10.41 subnet mask: 255.255.255.248, default gateway: 192.168.10.46
- EIP address: 192.168.10.254 subnet mask: 255.255.255.0, default gateway: 192.168.10.1
7How many bits must be borrowed from the host portion of an address to accommodate a router with five connected networks?
- Atwo
- Bthree
- Cfour
- Dfive
8A company has a network address of 192.168.1.64 with a subnet mask of 255.255.255.192. The company wants to create two subnetworks that would contain 10 hosts and 18 hosts respectively. Which two networks would achieve that? (Choose two.)
- A192.168.1.16/28
- B192.168.1.64/27
- C192.168.1.128/27
- D192.168.1.96/28
- E192.168.1.192/28
9In a network that uses IPv4, what prefix would best fit a subnet containing 100 hosts?
- A/23
- B/24
- C/25
- D/26
10Refer to the exhibit.
Given the network address of 192.168.5.0 and a subnet mask of 255.255.255.224, how many total host addresses are unused in the assigned subnets?- A56
- B60
- C64
- D68
- E72
11When developing an IP addressing scheme for an enterprise network, which devices are recommended to be grouped into their own subnet or logical addressing group?
- Aend-user clients
- Bworkstation clients
- Cmobile and laptop hosts
- Dhosts accessible from the Internet
12 A network administrator needs to monitor network traffic to and from servers in a data center. Which features of an IP addressing scheme should be applied to these devices?
- Arandom static addresses to improve security
- Baddresses from different subnets for redundancy
- Cpredictable static IP addresses for easier identification
- Ddynamic addresses to reduce the probability of duplicate addresses
13Which two reasons generally make DHCP the preferred method of assigning IP addresses to hosts on large networks? (Choose two.)
- AIt eliminates most address configuration errors.
- BIt ensures that addresses are only applied to devices that require a permanent address.
- CIt guarantees that every device that needs an address will get one.
- DIt provides an address only to devices that are authorized to be connected to the network.
- EIt reduces the burden on network support staff.
14Refer to the exhibit. A computer that is configured with the IPv6 address as shown in the exhibit is unable to access the internet. What is the problem?
- AThe DNS address is wrong.
- BThere should not be an alternative DNS address.
- CThe gateway address is in the wrong subnet.
