62

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

to determine the subnet to which the host belongs

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

True or False: Since Host-A has the IPv4 address and subnet mask 192.168.1.50 255.255.255.0, 192.168.1.1 and 192.168.2.100 would be on the same network as Host-A

False, 192.168.2.100 is not on the same network

True or False: Network Portion and Host Portion are NOT components of IPv4 addresses?

False, they are components of IPv4 addresses

True or False: In variable-length subnet masking, The size of each subnet may be different, depending on requirements.

True

True or False: Since Host-A has the IPv4 address and subnet mask 10.5.4.100 255.255.255.0, 10.5.4.1 and 10.5.4.99 would be on the same network as Host-A

True

True or False: Since Host-A has the IPv4 address and subnet mask 172.16.4.100 255.255.0.0, 172.16.0.1 and 172.16.4.99 would be on the same network as Host-A

True

True or False: the following 2 statements are true about private IPv4 addresses 1) Private IPv4 addresses are assigned to devices within an organization's intranet (internal network) 2) Any organization (home, school, office, company) can use the 10.0.0.0/8 address.

True

True or False: the following 2 statements are true about public IPv4 addresses 1) To access a device over the internet, the destination IPv4 address must be a public address. 2) Public IPv4 address exhaustion is a reason why there are private IPv4 addresses and why organizations are transitioning to IPv6.

True
