THE QUESTIONS AND ALSO THE ANSWARES 1. List the RFC 1918 private address ranges.

The private address range of the RFC 1918 is bellow: 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 2. True or false: You can use DHCP to specify the TFTP host’s IP address to a client PC.

The answare of questions above is true. 3. True or false: 255.255.255.248 and /28 are two representations of the same IP mask.

The answare of question above is false 4. True or false: Upper-layer protocols are identified in the IP header’s protocol field. TCP is protocol 6, and UDP is protocol 17.

The answare of question above is false 5. Fill in the blank: Without any options, the IP header is (65535 [216] -20) bytes in length. 6. The IP header’s ToS field is redefined as the DS field. How many bits does DSCP use for packet classification, and how many levels of classification are possible?

6 bits of 8 bits are used as DS point codes (DSCP) to define QoS requirements, while the remaining 2 bits are not currently used. 7. True or false: NAT uses different IP addresses for translations. PAT uses different port numbers to identify translations.

The answare of question above is true. 8. True or false: The IP header’s header checksum field performs the checksum of the IP header and data.

The answare of question above is true. 9. Calculate the subnet, the address range within the subnet, and the subnet broadcast of the address 172.56.5.245/22. Subnet First Host Last Host Broadcast

172.16.0.0 172.16.0.1 172.16.63.254 172.16.63.255

172.16.64.0 172.16.64.1 172.16.127.254 172.16.127.255

172.16.128.0 172.16.128.1 172.16.191.254 172.16.191.255

172.16.192.0 172.16.192.1 172.16.255.254 172.16..255.255



10. When packets are fragmented at the network layer, where are the fragments reassembled?

When the fragmentation, breaking it into small pieces, so packets can be established that can pass through links with smaller maximum transmission units (MTU) of the original datagram size. 11. Which protocol can you use to configure a default gateway setting on a host?

a. ARP b. DHCP c. DNS d. RARP A DHCP protocol can use to configure a default gateway setting on a host. 12. How many host addresses are available with a Class B network with the default mask?

a. 63,998 b. 64,000 c. 65,534 d. 65,536 65,535 host address are available with a Class B network with the default mask. 13. Which of the following is a dotted-decimal representation of a /26 prefix mask?

a. 255.255.255.128 b. 255.255.255.192 c. 255.255.255.224 d. 255.255.255.252 The numbers 255.255.255.192 is a dotted-decimal representation of a / 26 prefix mask.

14. Which

network

and

mask

summarize

both

the

192.170.20.16/30

and

192.170.20.20/30 networks?

a. 192.170.20.0/24 b. 192.170.20.20/28 c. 192.170.20.16/29



d. 192.170.20.0/30 The numbers 192.170.20.0/30 is a network and mask summarize both the 192.170.20.16/30 and 192.170.20.20/30 networks. 15. Which AF class is backward compatible with IP precedence bits’ flash traffic?

a. AF2 b. AF3 c. AF4 d. EF The AF Class is backward compatible with IP preceden ce bits flash traffic is EF. 16. Which of the following is true about fragmentation?

a. Routers between source and destination hosts can fragment IPv4 packets. b. Only the first router in the network can fragment IPv4 packets. c. IPv4 packets cannot be fragmented. d. IPv4 packets are fragmented and reassembled at each link through the network. The answare is true about fragmentation is Routers between source and destination hosts can fragment IPv4 packets. 17. A packet sent to a multicast address reaches what destinations?

a. The nearest destination in a set of hosts. b. All destinations in a set of hosts. c. Broadcasts to all hosts. d. Reserved global destinations. The destinations about packet sent to a multicast address reaches is to all destinations in a set of hosts. 18. What are three types of IPv4 addresses?

a. Anycast b. Multicast c. Dynamic d. Broadcast e. Unicast f. Global g. Static



Three types of IPv4 are : Multicast, Broadcast and Unicast. 19. Which devices should be assigned an IP address dynamically? (Select three.)

a. Cisco IP phones b. LAN switches c. Workstations d. Mobile devices e. Routers The devices should be assigned an IP address dynamically are : Cisco IP phone, LAN Switches and Routers. 20. Which name resolution method reduces administrative overhead?

a. Static name resolution b. Dynamic name resolution c. DHCP name resolution d. Host.txt name resolution The name resolution method reduces administrative overhead is a static name resolution 21. How

many

hosts

can

be

addressed

with

the

following

IPv4
