A+ - 5B - Use Basic TCP/IP Concepts

What is the purpose of a network prefix in an IPv4 address?

• To distinguish between the network number and host number

• To configure the default gateway parameter

• To identify a host within a particular IP network

• To allocate public IP addresses to customer networks

How is a network prefix expressed in slash notation?

• /32

• /24

• /16

• /8

What is the purpose of a subnet mask in IPv4 networking?

• To forward packets to other networks

• To divide a single IP network into multiple logical subnetworks

• To identify the default gateway

• To configure the DNS server addresses

When does a host assume that the packet must be routed to another IP network?

• When the masked portions of the source and destination IP addresses match

• When the destination interface is assumed to be on the same IP network

• When the subnet mask is configured with a block of valid public addresses

• When the source and destination network IDs match

What are the three private address ranges defined in the IPv4 address scheme?

• 172.16.0.0 to 172.31.255.255, 10.0.0.0 to 10.255.255.255, 192.168.0.0 to 192.168.255.255

• 192.168.0.0 to 192.168.255.255, 172.16.0.0 to 172.31.255.255, 10.0.0.0 to 10.255.255.255

• 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, 192.168.0.0 to 192.168.255.255

• 10.0.0.0 to 10.255.255.255, 192.168.0.0 to 192.168.255.255, 172.16.0.0 to 172.31.255.255

What are the address classes in the IPv4 address scheme?

• B, C, D, E

• A, B, D, E

• A, B, C, E

• A, B, C, D

How can internet access be facilitated for hosts using a private addressing scheme?

• Through a proxy server that fulfills requests for Internet resources on behalf of clients

• Both A and B

• Through a router configured with a single or block of valid public addresses

• None of the above

What are the two other parameters typically configured for a host to make it fully functional?

• Default gateway parameter and Domain Name System (DNS) server addresses

• Default gateway parameter and proxy server address

• Default gateway parameter and subnet mask

• Domain Name System (DNS) server addresses and subnet mask

How is an IPv4 address and subnet mask set manually in a static configuration?

• By entering the IP address as four octal numbers separated by periods and the subnet mask in octal notation

• By entering the IP address as four hexadecimal numbers separated by periods and the subnet mask in hexadecimal notation

• By entering the IP address as four binary numbers separated by periods and the subnet mask in binary notation

• By entering the IP address as four decimal numbers separated by periods and the subnet mask in dotted decimal notation

What is the valid range of host addresses in the IP network 192.168.0.0/24?

• 192.168.0.1 to 192.168.0.254

• 192.168.0.0 to 192.168.0.255

• 192.168.0.0 to 192.168.0.253

• 192.168.0.1 to 192.168.0.255
