CNIT 344 Exam 2 Questions With Correct
Answers
IPv4 - CORRECT ANSWER✔✔-connectionless (the sender doesn't know if the
| | | | | | | | | |
receiver is present or if the packet arrived or if the receiver can read the packet),
| | | | | | | | | | | | | | | |
unreliable (IP does not have the capability to manage and recover from
| | | | | | | | | | | |
undelivered or corrupt packets, so other protocol layers manage reliability),
| | | | | | | | | |
media independent |
32 bits/4 bytes - CORRECT ANSWER✔✔-Key piece of the IP Packet Header, length
| | | | | | | | | | | | |
of IPv4 header
| |
Type of service - CORRECT ANSWER✔✔-Key piece of the IP Packet Header, 8 1-bit
| | | | | | | | | | | | |
fields, QoS, DSCP
| | |
Flag and Fragment Offset - CORRECT ANSWER✔✔-Key piece of the IP Packet
| | | | | | | | | | | |
Header, used in reconstruction of any fragments
| | | | | |
Time to Live - CORRECT ANSWER✔✔-Key piece of the IP Packet Header,
| | | | | | | | | | | |
maximum hops before undeliverable | | |
Protocol - CORRECT ANSWER✔✔-Key piece of the IP Packet Header, upper layer
| | | | | | | | | | | |
protocol (TCP/UDP) |
, Source and destination address - CORRECT ANSWER✔✔-Key piece of the IP
| | | | | | | | | | |
Packet Header, the two 32 bit binary values
| | | | | | |
Network and host - CORRECT ANSWER✔✔-two parts of an IPv4 address
| | | | | | | | | |
Default gateway - CORRECT ANSWER✔✔-the address of the router interface,
| | | | | | | | | |
must be on the same network as all of the hosts
| | | | | | | | | |
Address resolution - CORRECT ANSWER✔✔-the process of mapping a hardware
| | | | | | | | | |
address to a higher-layer protocol address (maps IPv4 address to specific MAC
| | | | | | | | | | | |
address)
CIDR Notation - CORRECT ANSWER✔✔-putting a slash after an IPv4 address that
| | | | | | | | | | | |
represents the number of network bits, also known as classless routing
| | | | | | | | | |
Layer 2 - CORRECT ANSWER✔✔-MAC addresses are at this layer
| | | | | | | | |
Layer 3 - CORRECT ANSWER✔✔-Network address are at this layer
| | | | | | | | |
NAT - CORRECT ANSWER✔✔-allows hosts in a private network to use a different
| | | | | | | | | | | | |
IP address to access hosts and/or services on an external network, can be applied
| | | | | | | | | | | | |
|on source address or destination address
| | | | |
Inside local address - CORRECT ANSWER✔✔-an RFC 1918 address assigned to a
| | | | | | | | | | | |
host on an inside network
| | | |
