Question

1.The IXP acts as an interface between autonomous systems.

True

False

2. What is correct regarding a connectionless protocol such as IP?

a. Since no connection is established between source and destination, flow control is implemented in the IP standard

b. Although connectionless, an IP handshake between source and destination at the network layer is still required

c. As a connectionless protocol, IP does not guarantee datagram delivery

d. None of the above

3. Since IP is a connectionless protocol, each datagram must contain both source and destination network addresses.

True

False

4. Each IPv4 packet contains a "time-to-live" which prevents a packet from remaining in the network indefinitely .

True

False

Select the correct statement(s) regarding IP addresses.

a. Each IP address contains a network ID and host address

b. IPv4 class A, B, and C networks can be further divided into subnetworks through subnetting

c. Class Inter-domain routing (CIDR) notation identifies subnetwork IDs

d. All of the statements are correct

Explanation / Answer

1). False

serves as a backup link to permit traffic for moving in a scenario that a straight link collapse.

2). c.As a connectionless protocol, IP does not guarantee datagram delivery.

Because the internet protocol is not reliable and more over every packet is considered as a seperately from total remaining.

3).True

datagrams can route alone each other. i.e any single component collapse like router would not collapse the network.

4).True

The TTL feild is employed to increase the perfomance of network.It is 8 bits ling and guaged in seconds.

5). D. All of the statements are correct.
