Interview Question of CCNA Part 6

51- What is the subnetmask of / 27 in network based and host based ?

In network based 224 { 128+64+32}and in host based 248 (128+64+64+16+8)

52- What will be the prefix length of 224 in VLSM ?
27 (carry 3 bits from host (128+64+16=224) and add in network ports (24+3=27) )

53-How many valid IP will b in /21 in route Summarization?

1044

54- In which protocol you manually enable route summarization ?
OSPF

55 – In which protocol supenetting is enable by default?

RIPv2 and EIGRP

56- What is MAC address size of IPv6?

64 bits

57 – Default Packet Size of IPv6?
8 Bytes = 16*8 =128 bit

58- How many fillers we can put in one IP of IPv6?
ONE (:: called filler)

59- Which mathematically form used inIPv6?
Hexadecimal

60- What is quality of IPv6?

a) Router processing will rapid because field size wills 8 bytes (but in IPv4 it was 12 byres)

b) No Fragmentation

c) No Checksum

31- What is BIA ?

Burn in Address other name is MAC address

32- What is Size of IPv4 MAC Address?
48 Bits

33- Why MAC address called Physical address?
Because it’s not changeable

34- Who controls MAC address uniqueness and how
IEEE (Institute of Electrical Electronics and Engineering) Controls its uniqueness.
They divide 48 bits MAC address in two parts. First 24 bits part called OUI (Organizational unique identifier) and other 24 bits are device code.

35- How we can see MAC address from DOS Prompt?
ipconfig/all

36- Why IP address called logical address?
Private IP called logical address because they are change able.

37- What is the size of IPV4?
32 bits
38-What is Syntax of IPV4
. DOT

39- How many types of IPS?
Three Types of IP
1- Public
2- Private
3- Special IP

40- What are the ranges of private IPS?
A Class = 10.0.0.0 – 10.255.255.255
B Class = 172.16.0.0 – 172.31.255.255
C Class = 192.168.0.0 – 192.168.255.255

169.254.0.0 through 169.254.255.255 (APIPA only)

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
