Q:

What is a stub network?

A) A network with only one entry and no exit point. B) A network that has only one entry and exit point.
C) A network with more than one exit point. D) A network with more than one exit and entry point.
 
Answer & Explanation Answer: B) A network that has only one entry and exit point.

Explanation:

A stub network has only one default path to non-local hosts and no outside network knowledge. Non-local stub network traffic uses a single logical path when traveling in and out of the network.

 

Stub networks are essentially local area networks (LAN) that either do not connect to the outside and relay data packets internally or are dead-end LANs that know of only one network exit. Stub networks may have multiple connections but use one path to single points of destination.

 

Hence, a stub network is a network that has only one entry and exit point.

Q:

How are ip addresses available to the internet classified?

A) Static B) Public
C) Private D) None of the above
 
Answer & Explanation Answer: B) Public

Explanation:

An IP address (internet protocol address) is a numerical representation that uniquely identifies a specific interface on the network. Addresses in IPv4 are 32-bits long. This allows for a maximum of 4,294,967,296 (2^32) unique addresses. Addresses in IPv6 are 128-bits, which allows for 3.4 x 1038 (2^128) unique addresses.

 

IP addresses available to the internet are classified as Public.

Q:

What does a VLAN do?

A) Breaks up broadcast domains in a layer 2 switch internetwork B) Provides multiple broadcast domains within a single collision domain
C) Provides multiple collision domains on one switch port D) Acts as the fastest port to all servers
 
Answer & Explanation Answer: A) Breaks up broadcast domains in a layer 2 switch internetwork

Explanation:

virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). LAN is the abbreviation for local area network and in this context, virtual refers to a physical object recreated and altered by additional logic.

VLANs work by applying tags to network packets and handling these tags in networking systems – creating the appearance and functionality of network traffic that is physically on a single network but acts as if it is split between separate networks. In this way, VLANs can keep network applications separate despite being connected to the same physical network, and without requiring multiple sets of cabling and networking devices to be deployed.

Q:

What is usage of Sequence Number in Relaible Transmission?

Answer

The protocol specifies that frames need to be numbered. This is done by using sequence numbers. A field is added to the data frame to hold the sequence number of that frame. Since we want to minimize the frame size, the smallest range that provides unambiguous communication. The sequence numbers can wrap around.
