R&S1 Chapter 8.2 Exam

Which two network addresses can be assigned to the network containing 10 hosts? Your answers should waste the fewest addresses, not reuse addresses that are already assigned, and stay within the 10.18.10.0/24 range of addresses. (Choose two.) 10.18.10.0/26 10.18.10.192/29 10 hosts

- 10.18.10.208/28 - 10.18.10.224/28

What is the network address and broadcast address for: Device 2: IP address192.168.10.17/30

- 192.168.10.16 - 192.168.10.19

What is the network address and broadcast address for: Device 1: IP address 192.168.10.77/28

- 192.168.10.64 - 192.168.10.79

What are the benefits of subnetting?

- A new broadcast domain is created for every network that is created through subnetting. - The amount of network traffic that crosses the entire network decreases. - Devices can be grouped together to improve network management and security. - More IP addresses are usable because each network will have a network address and 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.)

- geographic location - device type

What are two benefits of subnetting networks? (Choose two.)

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

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?

255.255.255.224

A network administrator subnets the 192.168.10.0/24 network into subnets with /26 masks. How many equal-sized subnets are created?

4

How many host addresses are available on the 192.168.10.128/26 network?

A network administrator has received the IPv6 prefix 2001:DB8::/48 for subnetting. Assuming 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?

65536

What is the interface ID of the IPv6 address 2001:DB8::1000:A9CD:47FF:FE57:FE94/64?

Which IPv6 network prefix is only intended for local links and can not be routed?

FE80::/10

How do you calculate network and broadcast addresses?

Write the device IP address in binary. Draw a line showing where the subnet mask 1s end. Change all the bits to the right of the line to 0s to determine the network number. Change all the bits to the right of the line to 1s to determine the broadcast address.
