Basic CCNA Job Interview Questions

1: What is unicast and how does it work?

Unicast is a one-to-one transmission method. A single frame is sent from the
source to a destination on a network. When this frame is received by the switch,
the frame is sent on to the network, and the network passes the frame to its
destination from the source to a specific destination on a network.

2: What is multicast and how does it work?

** Multicast is a one-to-many transmission method. A single frame is sent from
the source to multiple destinations on a network using a multicast address. When
this frame is received by the switch, the frame is sent on to the network and the
network passes the frame to its intended destination group.

3:  What is broadcast and how does it work?

** Broadcast is a one-to-all transmission method. A single frame is sent from the
source to a destination on a network using a multicast address. When this frame
is received by the switch, the frame is sent on to the network. The network
passes the frame to all nodes in the destination network from the source to an
unknown destination on a network using a broadcast address. When the switch
receives this frame, the frame is sent on to all the networks, and the networks
pass the frame on to all the nodes. If it reaches a router, the broadcast frame is
dropped.

4: What is fragmentation?

** Fragmentation in a network is the breaking down of a data packet into smaller
pieces to accommodate the maximum transmission unit (MTU) of the network.

5: What is MTU? What’s the MTU for traditional Ethernet?

** MTU is the acronym for maximum transmission unit and is the largest frame
size that can be transmitted over a network. Messages longer than the MTU
must be divided into smaller frames. The network layer (Layer 3) protocol
determines the MTU from the data link layer (Layer 2) protocol and fragments the
messages into the appropriate frame size, making the frames available to the
lower layer for transmission without further fragmentation. The MTU for Ethernet
is 1518 bytes.

6: What is a MAC address?

** A MAC address is the physical address of a network device and is 48 bits (6
bytes) long. MAC addresses are also known as physical addresses or hardware
addresses.

7:  What is the difference between a runt and a giant, specific to traditional
Ethernet?

** In Ethernet a runt is a frame that is less than 64 bytes in length, and a giant is
a frame that is greater than 1518 bytes in length. Giants are frames that are
greater than the MTU used, which might not always be 1518 bytes.

8: What is the difference between store-and-forward and cut-through
switching?

** Cut-through switching examines just the frame header, determining the output
switch port through which the frame will be forwarded. Store-and-forward
examines the entire frame, header and data payload, for errors. If the frame is
error free, it is forwarded out its destination switch port interface. If the frame has
errors, the switch drops the frame from its buffers. This is also known as
discarding the frame to the bit bucket.

9: What is the difference between Layer 2 switching and Layer 3 switching?

* * Layer 2 switches make their forwarding decisions based on the Layer 2 (data
link) address, such as the MAC address. Layer 3 switches make their forwarding
decisions based on the Layer 3 (network) address.

10: What is the difference between Layer 3 switching and routing?

** The difference between Layer 3 switching and routing is that Layer 3 switches
have hardware to pass data traffic as fast as Layer 2 switches. However, Layer 3
switches make decisions regarding how to transmit traffic at Layer 3 in the same
way as a router. A Layer 3 switch cannot use WAN circuits or use routing
protocols; a router is still required for these functions.

11- What is the difference between bus topology and HUB?

Hub is Centralized device ( series ) .Bus topology is Decentralized device (in parallel)

12- Is hub intelligent device?
No; because it not use header

12- Which protocol switch use for filling its MAC-Table ?
ARP – Address Resolution Protocol

13- What is CAM ?
Content Address Memory. its another name of MAC address table.

14- Which type for communication switch do?
In case of any new event switch do broadcast, after that always do Unicast.

15- If line down and protocol also down; in this case which layer move problem?
Physical Layer – Layer 1

16 – If line up, but protocol down which layer should be troubleshot?
Data link problem – Layer 2

17-On which base switches take decisions?
Mac Address

18- How ARP brings MAC address for switch?
Through Broadcast

19- How many collision domains are in switch?
Equal number of ports

20- How many broadcast domains are in Switch ?
One

1- Define Network?

Communication, Resource sharing and Media (When multiple host share their resources with each other OR when multiple devices connect with each other for resource sharing )

2 – Types of communication in IPv4?
Unicast, Multicast and Broad cast

3 – Types of communication in IPv6 ?
Unicast, Multicast and Anycast

4- Types of Resource Sharing?
Intranet , Extranet and Internet .

5- What is Collision?
When signal hits each other, collision accord.

6- Which Type of Transmission Bus Topology Support?
Half Duplex

7- What is the difference between half duplex and full duplex?
In half duplex, sender should b one. In full duplex, sender can be multiple.

8- Which way of communication bus topology use?
Broadcast

9- If there is only 2 Host in Bus Topology is that possible collision accord?
Yes, because end terminal will not absorb signals. Signal will be bounce back and collision will accord.

10- HUB in Star topology or Bus Topology?
In star topology, but logically works like a bus topology.
