CCNA Interview Questions

After Review CCNA course we Conclude some short Questions with Answers

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
