M2Q6: Intro to IP & Routing Flashcards
Module 2: Quiz 6
IP (Internet Protocol) provides a logical addressing scheme.
A. True
B. False
A. True
Explanation: IP addresses are logical addresses that can be easily changed at any time while MAC addresses are physical addresses that are “burned in” to the NIC hardware of a device.
An IPv4 address is comprised of how many binary bits?
A. 8
B. 12
C. 32
D. 48
C. 32
Explanation: IP version 4 addresses are made up of 4 sets of 8 bits equaling a total of 32 bits.
An IP address defines that a device is part of a particular network.
A. True
B. False
A. True
Explanation: An IP address determines the IP network that a host or device belongs to and in combination with a MAC address defines it’s exact location on the network.
Internet Protocol is included as part of which protocol stack?
A. Ethernet
B. The OSI Model
C. Broadcast stack
D. TCP/IP
D. TCP/IP
Explanation: The TCP/IP protocol stack includes IP (Internet Protocol). Ethernet is a family of protocols, works below IP and does not include IP. The OSI Model is not a stack of specific protocols, but rather a model for interpreting and managing protocols, applications, hardware, and systems. Broadcast stack is not a real thing and conveys no intended meaning.
An IP router is used to route IP Packets from one network to ______________________.
A. Another network
B. The OSI Model
C. A Frame
D. An Access Point
A. Another Network
Explanation: Routers look at the destination IP addresses inside IP Packets and reference their routing tables to make decisions on how to correctly route the IP traffic to the destination network. In this way IP routers are used to route traffic from one network to another network.
IP by itself is a connection-oriented protocol.
A. True
B. False
B. False
Explanation: By itself, IP is connection-less. In order to become connection-oriented it must be combined with a connection-oriented protocol from the Transport layer of the OSI model such as TCP.
Before being sent out onto the network IP Packets are first encapsulated inside of a___________.
A. Datagram
B. Frame
C. LAN
D. IP Packet
B. Frame
Explanation: An IP Packet or Datagram resides at the OSI Network Layer and is encapsulated inside of a Frame as it moves down to the OSI Data Link Layer. The Frame is then placed on the physical medium as bits (ones and zeros).
The IPv4 Networks 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 are examples of what type of IPv4 addressing?
A. Public
B. Hybrid
C. Private
D. Connection-oriented
C. Private
Explanation: The RFC 1918 network IDs are used for private networks are not routable on the public internet. These ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.
To interface with the IPv4 internet what type of IPv4 addressing must be used on the internet facing device?
A. Public
B. Hybrid
C. Private
D. Connection-oriented
A. Public
Explanation: Public IPv4 networks are assigned to the global internet registries by IANA. These public networks are routable on the public internet where as the RFC 1918 private network ranges are not routable on the public internet.
