2001:D12:AA04:B5::/64

A network engineer is subnetting the 10.0.240.0/20 network into smaller subnets. Each new subnet will contain between a minimum of 20 hosts and a maximum of 30 hosts. Which subnet mask will meet these requirements? a.) 255.255.255.240 b.) 255.255.240.0 c.) 255.255.255.224 d.) 255.255.255.240

255.255.255.224

4

How many host addresses are available on the 192.168.10.128/26? a.) 30 b.) 32 c.) 60 d.) 62 e.)64

62

A network administrator has received the IPv6 prefix 2001:DB8::48/48 for subnetting. Assume the administrator does not subnet into the interface ID portion of the address space, how many subnets can the administrator create from the /48 prefix? a.) 16 b.) 256 c.) 4096 d.) 65536

65536

Three methods allow IPv6 and IPv4 to co-exist. Match each method with its description . (Not all options are used.) a.) The IPv4 packets and IPv6 packets coexist in the same network b.) The IPv6 packets is transported inside an IPv4 packet c.)IPv6 packets are converted into IPv4 packets, and vice versa i. dual-stack ii. tunneling iii. translation

The IPv4 packets and IPv6 packets coexist in the same network --> dual-stack The IPv6 packets is transported inside an IPv4 packet --> tunneling IPv6 packets are converted into IPv4 packets, and vice versa --> translation

Three devices are on three different subnets. Match the networks address and the broadcast address with each subnet where these devices are located. (Not all options are used.) a.) Subnet 1 network number b.) Subnet 1 broadcast address c.) Subnet 2 network number d.) Subnet 3 broadcast address e.) Subnet 3 network number f.) Subnet 3 broadcast address i. 192.168.10.64 ii. 192.168.10.79 iii. 192.168.10.16 iv. 192.168.10.19 v. 192.168.10.32 vi. 192.168.10.39

a.) Subnet 1 network number --> 192.168.10.64 b.) Subnet 1 broadcast address --> 192.168.10.79 c.) Subnet 2 network number --> 192.168.10.16 d.) Subnet 3 broadcast address --> 192.168.10.19 e.) Subnet 3 network number --> 192.168.10.32 f.) Subnet 3 broadcast address --> 192.168.10.39

What does the IP address 192.168.1.15/29 represent? a.) subnetwork address b.) multicast address c.) unicast address d.) broadcast address

broadcast address

A college has five campuses. Each campus has IP phones installed. Each campus has an assigned IP address range. For example, one campus has IP addresses that start with 10.1.x.x. On another campus the address range is 10.2.x.x. The college has standardized that IP phones are assigned IP addresses that have the number 4X in the third octet. For example, at one campus the address ranges used with phones include 10.1.40.x, 10.1.41.x, 10.1.42.x, etc. Which two groupings were used to create this IP addressing scheme? (Choose two.) a.) geographic loction d.) device type c.) department d.) personnel type e.) support model

geographic location device type

What are two benefits of subnetting networks? (Choose two.) a.) combining multiple smaller networks into larger networks b.) reducing the size of broadcast domains c.) decreasing the number of broadcast domains d.) grouping devices to improve management and security e.) increasing the size of collision domains

reducing the size of broadcast domains grouping devices to improve management and security

An administrator wants to create four subnetworks from the network address 192.168.1.0/24. What is the network address and subnet mask of the second usable subnet? a.) subnetwork 192.168.1.64 subnet mask 255.255.255.192 b.) subnetwork 192.168.1.64 subnet mask 255.255.255.240 c.) subnetwork 192.168.1.64 subnet mask 255.255.255.240 d.) subnetwork 192.168.1.128 subnet mask 255.255.255.224 e.) subnetwork 192.168.1.8 subnet mask 255.255.255.224
