1 Subnetting Questions: Question 1 You have been asked to come up with a subnet mask that will allow all three servers to be on the same network while providing the maximum number of subnets. Which network address and subnet mask meet this requirement? A B C D E Question 2 Which subnet mask would be appropriate for a network address range to be subnetted for up to eight subnets, with each Subnet containing 5 to 26 hosts? A B C D E

2 Question 3 An administrator must assign static IP addresses to the servers in a network. For network /29, the router is assigned the first usable host address while the sales server is given the last usable host address. Which of the following should be entered into the IP properties box for the sales server? A. IP address: Subnet Mask: Default Gateway: B. IP address: Subnet Mask: Default Gateway: C. IP address: Subnet Mask: Default Gateway: D. IP address: Subnet Mask: Default Gateway: E. IP address: Subnet Mask: Default Gateway:

3 Question 4 Find out: I. Subnet Mask II. Maximum Number of Hosts in Each Subnet III. Maximum Number of Subnets of Subnet addresses /29? Question 5 You are working in a data center environment and are assigned the address range /23. You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts in each. Which IP address range meets these requirements? A /27 B /26 C /29 D /28 E /25

4 Question 6 Which two benefits are provided by using a hierarchical addressing network addressing scheme? (Choose two) A. reduces routing table entries B. auto-negotiation of media rates C. efficient utilization of MAC addresses D. dedicated communications between devices E. ease of management and troubleshooting Question 7 The network administrator is asked to configure 113 point-topoint links. Which IP addressing scheme best defines the address range and subnet mask that meet the requirement and waste the fewest subnet and host addresses? A /18 subnetted with mask B /25 subnetted with mask C /24 subnetted with mask D /23 subnetted with mask E /16 subnetted with mask

5 Question 8 Given an IP address with a subnet mask of , what is the correct network address? A B C D Question 9 What is the maximum number of IP addresses that can be assigned to hosts on a local subnet that uses the subnet mask? A. 14 B. 15 C. 16 D. 30 E. 31 F. 62

6 Question 10 You have a network that needs 29 subnets while maximizing the number of host addresses available on each subnet. How many bits you must borrow from the host field to provide the correct subnet mask? A. 2 B. 3 C. 4 D. 5 E. 6 F. 7 Question 11 What is the subnet address for a host with the IP address /28? A B C D

7 Question 12 The network address of /19 provides how many subnets and hosts? A. 7 subnets, 30 hosts each B. 7 subnets, 2,046 hosts each C. 7 subnets, 8,190 hosts each D. 8 subnets, 30 hosts each E. 8 subnets, 2,046 hosts each F. 8 subnets, 8,190 hosts each Question 13 Which two statements describe the IP address /23? (Choose two.) A. The subnet address is B. The lowest host address in the subnet is C. The last valid host address in the subnet is D. The broadcast address of the subnet is E. The network is not subnetted.

8 Question 14 If a host on a network has the IP address /30, to which subnet address this Host belongs to? A B C D E Question 15 Which mask should you use on point-to-point WAN links in order to reduce the waste of IP addresses? A. /27 B. /28 C. /29 D. /30 E. /31

9 Question 16 What is the subnet address of a host with an IP address of /21? A B C D Question 17 You need to configure a server that is on the subnet /29. The router has The first available host addresses. Which of the following should you assign to the server? A B C D E

10 Question 18 You have an interface on a router with the IP address of /29. What is the broadcast address the hosts will use on this LAN? A B C D E Question 19 You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which subnet mask would you use? A B C D
