A workstation has been assigned the following IP addressing information: • IP address: 192.168.1.26 • Subnet mask: 255.255.255.0 Default gateway: 192.168.1.254 • DNS server: 192.168.1.1 Given this information, what is the IP address of the network where this host resides?

192.168.1.0

Which of the following are private IP addresses? (Select two.)

192.168.250.11 10.244.12.16

Your network has a network address of 172.17.0.0 with a subnet mask of 255.255.255.0. Which of the following are true concerning this network? (Select two.)

254 host addresses are available. 172.17.2.0 is a valid subnet.

Your network has been assigned 200.55.6.0 as the network address. You have determined that you need four subnets. Which subnet mask should you use to provide four subnets?

255.255.255.192

Your network uses a network address of 137.65.0.0 with a subnet mask of 255.255.0.0. How many address are available for assignment to network hosts on this network?

65534

Which of the following are characteristics of ISATAP for IPv6 tunneling? (Select two.)

Dual stack routers Dual stack hosts

You are working on a workstation with the following MAC address: 10-01-64-AB-78-96 Which of the following will be the link-local address using the modified EUI-64 format?

FE80::1201:64FF:FEAB:7896

You need to design an IPv6 addressing scheme for your network. The following are key requirements for your design: Infrastructure hosts, such as routers and servers, will be assigned static interface IDs while workstations, notebooks, tablets, and phones will be assigned interface IDs dynamically. Internet access must be available to all hosts through an ISP. Site-to-site WAN connections will be created using leased lines. Which type of IPv6 addressing is most appropriate for hosts in this network?

Global Unicast Addressing

Your company wants to begin the transition from IPv4 to IPv6. You want to stage the implementation on a host-by-host basis. You will enable IPv6 on existing hosts as time and budget allows. During the transition, all hosts in your site need to communicate with all other hosts. IPv6 should be used between hosts when both hosts support IPv6. NAT support is not required. Which method should you use?

ISATAP

You need to design a network that supports 275 hosts. You want to place all hosts in a single broadcast domain, and you want to make sure you do not waste IP addresses. How should you implement your plan?

Place all hosts on the same subnet. Use a mask of 255.255.254.0.

You have a small network with three subnets as shown in the exhibit. IP addresses for each router interface are also indicated. How many IP addresses on each subnet remain that can be assigned to hosts?

SubnetA = 125, SubnetB = 0, SubnetC = 13

When calculating how many subnets are available for a given IP address and subnet mask, when should you use the 2^n - 2 formula? (Select two.)

The no ip subnet zero command is configured The network uses a classful routing protocol, such as RIP version 1 or IGRP

Your organization has been assigned a registered global routing prefix of 2001:FEED:BEEF::/48 by an ISP. Using your organization's IPv6 addressing scheme, you've used the next 16 bits beyond the global routing prefix to define the following subnets: • 2001:FEED:BEEF:0001::/64 • 2001:FEED:BEEF:0002::/64 • 2001:FEED:BEEF:0003::/64 • 2001:FEED:BEEF:0004::/64 You need to statically assign an interface ID of 0000:0000:0000:0001 to the router interface connected to the 2001:FEED:BEEF:0003::/64 subnet. Which interface configuration command would you use to do this?

ipv6 address 2001:FEED:BEEF:0003::1/64

Which IPv6 address type is only valid within a subnet?

link-local

You have a single router with three subnets as shown in the Exhibit. Each subnet has the number of hosts specified. You need to select a subnet mask for each subnet that provides sufficient host addresses without wasting addresses. Which mask values should you use?

• SubnetA = 255.255.255.192 • SubnetB = 255.255.255.224 • SubnetC = 255.255.255.128
