Test 5 - CCNA 1

What does the IP address 172.17.4.250/24 represent?

• • broadcast address

• • host address

• • multicast address

• • network address

If a network device has a mask of /28, how many IP addresses are available for hosts on this network?

What is the purpose of the subnet mask in conjunction with an IP address?

• • to mask the IP address to outsiders

• • to uniquely identify a host on a network

• • to determine the subnet to which the host belongs

• • to identify whether the address is public or private

A network administrator is variably subnetting a network. The smallest subnet has a mask of 255.255.255.224. How many usable host addresses will this subnet provide?​

What subnet mask is represented by the slash notation /20?

1.      Which statement is true about variable-length subnet masking

• • Bits are returned, rather than borrowed, to create additional subnets.

• • Subnets may only be subnetted one additional time.

• • The size of each subnet may be different, depending on requirements.

• • Each subnet is the same size.

Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?

• • to identify the network address of the destination network

• • to identify faulty frames

• • to identify the host address of the destination host

• • to identify the broadcast address of the destination network

How many usable IP addresses are available on the 192.168.1.0/27 network?

Which subnet mask would be used if exactly 4 host bits are available?

Which two parts are components of an IPv4 address?

• • subnet portion

• • broadcast portion

• • physical portion

• • host portion

• • network portion
