Lets have a look at below Lists of Short Descriptive type Questions with Answers
1. What are the responsibilities of Network Layer?
The Network Layer is responsible for the source-to-destination delivery of packet possibly across multiple networks (links).
a. Logical Addressing
2. What is DHCP?
The Dynamic Host Configuration Protocol has been derived to provide dynamic configuration. DHCP is also needed when a host moves from network to network or is connected and disconnected from a network.
3. Define ICMP?
Internet Control Message Protocol is a collection of error messages that are sent back to the source host whenever a router or host is unable to process an IP datagram successfully.
4. What is BOOTP?
BOOTSTRAP Protocol is a client/server protocol designed to provide the following four information for a diskless computer or a computer that is booted for the first time. IP address, Subnet mask, IP address of a router, IP address of a name server.
5. What is the need of internetwork?
To exchange data between networks, they need to be connected to make an Internetwork.
6. What are the types of class full addressing?
The types are Class A, Class B, Class C, Class D, Class E
7. What do you mean by ARP?
ARP stands for Address resolution protocol, maps an IP address to a MAC address
8. What do you mean by RARP?
RARP stands for Reverse Address resolution protocol, maps an MAC address to a IP address
9. Define Delivery of a packet.
It refers to the way a packet is handled by the underlying network under the control of network layer
10. What are the types of delivery?
There are two types of delivery
1. Direct delivery
2. Indirect delivery
11. What is class less addressing?
Classless addressing requires hierarchical and geographical routing to prevent immense routing tables
12. What is Unicast & Multicast communication?
Unicast communication is one source sending a packet to one destination. Multicast communication is one source sending a packet to multiple destinations.
13. What do you mean by Net id & Host id?
The Internet address (or IP address) is 32 bits (for IPv4) that uniquely and universally defines a host or router on the Internet. The portion of the IP address that identifies the network is called the net id. The portion of the IP address that identifies the host or router on the network is called the host id.
14. Define forwarding.
It refers to a way a packet is delivered to next station. It requires a host or a Router to have a routing table
15. What are the common notations used for address?
The two common notations used for address are
- Binary notations
- Dotted decimal notations
16. What are the advantages of IPV6 over IPV4?
- Larger address space
- Better header format
- New options
- Support for more security
17. Define static mapping.
It creating a table that associates an IP address with a MAC address
18. Compare direct delivery & indirect delivery
In direct delivery source and destination node belong to e same network In indirect delivery source and destination node belong to different network
19. What are the rules of non boundary-level masking?
- The bytes in the IP address that corresponds to 255 in the mask will be repeated in the Sub network address
- The bytes in the IP address that corresponds to 0 in the mask will change to 0 in the sub network address
- For other bytes, use the bit-wise AND operator
20. What is Fragmentation?
Fragmentation is the division of a datagram into smaller units to accommodate the MTU of a data link protocol.
