Introduction to Networks (Version 6.00) - ITN Chapter 8 Exam

Consider the following range of addresses: 2001:0DB8:BC15:00A0:0000:: 2001:0DB8:BC15:00A1:0000:: 2001:0DB8:BC15:00A2:0000:: ... 2001:0DB8:BC15:00AF:0000:: The prefix-length for the range of addresses is ____________

/60

A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 192.168.10.0/24. There are 3 printers on this network that need to use reserved static IP addresses from the pool. How many IP addresses in the pool are left to be assigned to other hosts? 1) 251 2) 253 3) 254 4) 252

1) 251

How many bits must be borrowed from the host portion of an address to accommodate a router with five connected networks? 1) three 2) two 3) five 4) four

1) three

A network administrator wants to have the same network mask for all networks at a particular small site. The site has the following networks and number of devices: IP phones - 22 addresses PCs - 20 addresses needed Printers - 2 addresses needed Scanners - 2 addresses needed The network administrator has deemed that 192.168.10.0/24 is to be the network used at this site. Which single subnet mask would make the most efficient use of the available addresses to use for the four subnetworks? 1) 255.255.255.192 2) 255.255.255.240 3) 255.255.255.224 4) 255.255.255.252 5) 255.255.255.0 6) 255.255.255.248

3) 255.255.255.224

4) 72

Refer to the exhibit. Given the network address of 192.168.5.0 and a subnet mask of 255.255.255.224 for all subnets, how many total host addresses are unused in the assigned subnets? 1) 64 2) 60 3) 56 4) 72 5) 68

2) 4

Refer to the exhibit. How many broadcast domains are there? 1) 1 2) 4 3) 2 4) 3

What is the prefix for the host address 2001:DB8:BC15:A:12AB::1/64? a) 2001:DB8:BC15 b) 2001:DB8:BC15:A c) 2001:DB8:BC15:A:1 d) 2001:DB8:BC15:A:1

b) 2001:DB8:BC15:A

What is the prefix for the host address 2001:DB8:BC15:A:12AB::1/64? What are two reasons a network administrator might want to create subnets? (Choose two.) a) reduction in number of switches needed b) reduction in number of routers needed c) easier to implement security policies d) simplifies network design e) improves network performance

c) easier to implement security policies e) improves network performance
