Which layer encapsulates the segment into packets?.
- A.
Physical
- B.
Data link
- C.
Network
- D.
Transport
Correct Answer
C. NetworkExplanation
The network layer encapsulates the segment into packets. This layer is responsible for routing and forwarding packets across different networks. It adds a header to the segment, which includes the source and destination IP addresses, to create a packet. The network layer ensures that packets are delivered to the correct destination by using routing protocols and addressing schemes.Rate this question:

Which three statements best describe a Local Area Network (LAN)? (Choose three.)
- A.
A LAN is usually in a single geographical area.
- B.
The network is administered by a single organization.
- C.
The connection between segments in the LAN is usually through a leased connection.
- D.
The security and access control of the network are controlled by a service provider.
- E.
A LAN provides network services and access to applications for users within a common organization.
- F.
Each end of the network is generally connected to a Telecommunication Service Provider (TSP).
Correct Answer(s)
A. A LAN is usually in a single geograpHical area.
B. The network is administered by a single organization.
E. A LAN provides network services and access to applications for users within a common organization.Explanation
A Local Area Network (LAN) is a network that typically covers a small geographical area, such as an office building or a campus. It is administered by a single organization, meaning that the organization has control over the network's operations and management. A LAN provides network services and access to applications for users within the organization, allowing them to communicate and share resources. Therefore, the statements "A LAN is usually in a single geographical area," "The network is administered by a single organization," and "A LAN provides network services and access to applications for users within a common organization" accurately describe a LAN.Rate this question:

What is the purpose of the TCP/IP Network Access layer?
- A.
Path determination and packet switching
- B.
Data representation, encoding, and control
- C.
reliability, flow control, and error detection
- D.
Detailing the components that make up the physical link and how to access it
- E.
The division of segments into packets
Correct Answer
D. Detailing the components that make up the pHysical link and how to access itExplanation
The purpose of the TCP/IP Network Access layer is to provide detailed information about the components that make up the physical link and how to access it. This layer is responsible for specifying the physical and electrical characteristics of the network, such as the type of cable to be used, the connectors, and the transmission rates. It also defines protocols for data transmission and reception, including how data is formatted and how devices on the network can access the physical medium.Rate this question:

What are the key functions of encapsulation? (Choose three.)
- A.
Allows modification of the original data before transmission
- B.
Identifies pieces of data as part of the same communication
- C.
Enables consistent network paths for communication
- D.
Ensures that data pieces can be directed to the correct receiving end device
- E.
Enables the reassembly of complete messages
- F.
Tracks delay between end devices
Correct Answer(s)
B. Identifies pieces of data as part of the same communication
D. Ensures that data pieces can be directed to the correct receiving end device
E. Enables the reassembly of complete messagesExplanation
Encapsulation is a process in which data is wrapped or encapsulated into a packet or frame before it is transmitted over a network. It helps in organizing and managing the data during communication.
The key functions of encapsulation mentioned in the answer are:
1. Identifies pieces of data as part of the same communication: Encapsulation adds headers and trailers to the data, which helps in identifying and grouping related data together.
2. Ensures that data pieces can be directed to the correct receiving end device: Encapsulation includes addressing information in the headers, which ensures that the data reaches the intended destination device.
3. Enables the reassembly of complete messages: Encapsulation adds sequence numbers and other information to the data, which allows the receiving device to reassemble the data packets in the correct order to reconstruct the complete message.Rate this question:

What device is considered an intermediary device?
- A.
file server
- B.
IP phone
- C.
laptop
- D.
Printer
- E.
Switch
Correct Answer
E. SwitchExplanation
A switch is considered an intermediary device because it operates at the data link layer of the OSI model and is responsible for forwarding data packets between devices on a local area network (LAN). It receives data packets from one device and then determines the appropriate destination device based on the MAC address. The switch then forwards the data packet only to the intended recipient, improving network efficiency and reducing congestion. Unlike the other options listed, a switch specifically functions as an intermediary device for network communication.Rate this question:
