World of Computer Networking Your CCNA start - Summaryr "Internet Protocol (IP) Addressing and Internet Protocol (IP) Pa

The video tutorial covers the network layer of the TCP model, focusing on IP addresses, their formats, and differences between IP version 4 and 6. It explains the roles of MAC and IP addresses, the function of routers, and the distinctions between LAN and WAN. The tutorial also discusses IP address classes, localhost, and the differences between private and public IP addresses, including NAT. It concludes with an explanation of static vs dynamic IP addresses and the structure of the IP version 4 header.

What is one disadvantage of a switched network?

• It requires more routers.

• Broadcast frames can slow down the network.

• It cannot connect to the internet.

• It only supports IPv6.

How many bits are in an IPv4 address?

• 32 bits

• 128 bits

• 16 bits

• 64 bits

Which type of IP address is used for point-to-point communication?

• Unicast

• Anycast

• Broadcast

• Multicast

What is the primary function of a router?

• To assign IP addresses

• To interconnect different networks

• To store MAC addresses

• To convert IPv4 to IPv6

What is the main difference between a LAN and a WAN?

• LANs are under common administration, WANs are not.

• LANs are larger than WANs.

• WANs are faster than LANs.

• LANs use IPv6, WANs use IPv4.

Which class of IP addresses is reserved for multicasting?

• Class D

• Class B

• Class E

• Class A

What is the purpose of Network Address Translation (NAT)?

• To assign static IP addresses

• To encrypt data packets

• To allow private IP addresses to access the internet

• To convert MAC addresses to IP addresses

What is a characteristic of a static IP address?

• It is assigned by DHCP.

• It is only used for private networks.

• It changes frequently.

• It remains constant for a device.

Which field in the IPv4 header is used to prevent infinite looping?

• Checksum

• TTL (Time to Live)

• Protocol

What does the DSCP field in the IPv4 header indicate?

• The destination IP address

• The protocol type

• The source IP address

• Packet prioritization
