The Internet 1 (Chapter 39)

A set of rules for allocating locally unique IP addresses to devices as they connect to a network

• DHCP

• TCP/IP

• APCS

• HTTPS

What is the expanded name of the acronym DHCP?

• Dynamic Host Configuration Protocol

• Dynamic Toast Configure Process

• Dual Host Configuration Process

• Deadline Host Configuration Procedure

Which two tasks does the Dynamic Host Configuration Protocol perform?

• Set the IP gateway to be used by the network.

• Sends a message offering an IP address, a subnet mask, and a lease duration.

• Assigns and returns an IP address from the default pool.

• Performs host discovery.

• Monitors IP performance.

Which subnet mask (in dotted decimal) would identify that the first 24 bits of an IP address are for the network?

• 255.255.255.0

• 255.0.0.0

• 0.0.0.255

• 0.255.255.255

What is responsible for converting IP addresses as packets pass between public and private address spaces

• NAT

• DHCP

• DNS

• HTTP

Which are two benefits of using NAT?

• It enhances network security because private networks are not advertised.

• Accelerated routing because no modifications are made on the packets.

• Performance bottlenecks, especially in high-traffic environments.

• It eliminates the need for every device attached to the internet to have a unique public address.

Typically, which network device would be used to perform NAT?

• DHCP server

• Hub

• Router

• NIC

Which three of the following IP addresses are private?

• 66.102.0.2

• 192.168.1.17

• 91.125.164.102

• 172.16.240.240

• 10.128.40.17

Sockets are different from ports because

• They include IP addresses

• They are defined in the Application Layer

• They use the OSI model

• They are just another term for the same thing

What happens when non-routable IP packets end up on the public internet?

• Sent to the default gateway

• Given a low priority type of service

• Discarded immediately

• Their IPv6 address is always used
