What are three key factors to consider when grouping hosts into a common network?

Which of the following are not functions of the network layer? (Choose two)
Routing, addressing packets with an IP address, delivery reliability, application data analysis, encapsulation, decapsulation

Delivery reliability and application data analysis. The first is a transport layer concern, and the second is the presentation layer. Routing, addressing packets with an IP adress, encapsulation and decapsulation are functions of the network layer.

Which of the following are true about IP? (Choose two)
- IP stands for International Protocol
- It is the most common network layer protocol
- It analyzes presentation layer data
- It operates at OSI layer 2
- It encapsulates transport layer segments

What is the name of the process of removing the OSI Layer 2 information from an IP packet?

Which of the following is true about IP?
- It is connection-oriented.
- It uses application data to determine the best path.
- It is used by both routers and hosts.
- It is reliable.

It is used by both routers and hosts. The second one is incorrect because IP uses addressing information in the header to determine the best path for the packet. "Reliable" is incorrect because IP is only a "best effort" protocol

Which of the following are true about network layer encapsulation? (Choose two).
- It adds a header to the segment.
- It can happen many times on the path to the destination host.
- It is performed by the last router on the path.
- Both source and destination IP addresses are added.
- It converts transport layer information into a frame.

It adds a header, and adds both source and destination IP addresses.
Network layer encapsulation happens only on the original host; other devices can read the data, but they do not remove or alter it until the destination network is reached.

Which of the following are true about TCP and IP? (Choose two).
- TCP is connectionless and IP is connection-oriented.
- TCP is reliable and IP is unreliable.
- IP is connectionless and TCP is connection-oriented.
- TCP is unreliable, and IP is reliable.
- IP operates at the transport layer.

2nd and third choices are correct--TCP is reliable and connection-oriented. IP is the one that's unreliable and connectionless. IP operates at the network layer.

TCP is a ________________ layer protocol.

How many bits are in an IPv4 address?

How many bits are in an IPv6 address?

Which of the following are true about static and dynamic routing?
- Static routing requires a routing protocol such as RIP.
- A default is a dynamic route.
- Dynamic routing adds packet-processing overhead.
- Administrative overhead is reduced with static routing.
- Routers can use static and dynamic routing simultaneously

IP requires that each sending and receiving device have a __________ IP address.

When an OSI Layer 4 PDU has been encapsulated at the network layer it is called a ______________.

For a network layer packet to travel between hosts, it must be handed down to the _________________ layer, for another layer of encapsulation called framing, and then encoded and put onto the ____________ layer to be sent to the next router.

What information does a router need to successfully forward packets?

What is a broadcast domain?

A broadcast domain is a logical part of a network (a network segment) in which any network equipment can transmit data directly to another equipment or device without going through a routing device (assuming the devices share the same subnet and use the same gateway; also, they must be in the same VLAN).
Specifically, the broadcast domain is that certain area of the computer network that's composed by every single computer or network equipment that can be reached directly by sending a simple frame to the data link layer's broadcast address.
