Using a 3-way handshake to establish a connection-oriented session ____________ is the protocol used to guarantee delivery of segments at the transport layer.
- Tcp
- Udp
- Ip
- Sip
Correct Answer

A. Tcp

Explanation

Using a 3-way handshake to establish a connection-oriented session is a characteristic of the TCP (Transmission Control Protocol). TCP ensures the reliable delivery of segments at the transport layer by using sequence numbers, acknowledgments, and retransmissions. This protocol guarantees that data sent from one device to another will be received accurately and in the correct order. UDP (User Datagram Protocol) is a connectionless protocol that does not provide the same level of reliability as TCP. IP (Internet Protocol) is responsible for routing packets across networks, while SIP (Session Initiation Protocol) is used for establishing and terminating multimedia sessions.

UDP does not guarantee delivery of segments in any form and is therefore known as a ________________________ protocol.
- Internet
- Control
- Host to host
- Connectionless
Correct Answer

A. Connectionless

Explanation

UDP (User Datagram Protocol) does not guarantee the delivery of segments, meaning that it does not ensure that the data sent from one host will reach the destination host. This lack of guarantee makes UDP a connectionless protocol, as it does not establish a formal connection between the sender and receiver. Unlike TCP (Transmission Control Protocol), which provides reliability through acknowledgments and retransmissions, UDP is used when speed and efficiency are more important than data integrity. Therefore, the correct answer is "connectionless."

This device breaks up broadcast domains and keeps track of and connects networks together.
- Hub
- Switch
- Router
- Bridge
- Console
Correct Answer

A. Router

Explanation

A router is a device that breaks up broadcast domains and keeps track of and connects networks together. Unlike a hub or switch, which simply forwards data to all connected devices, a router examines the destination IP address of each packet and determines the best path for it to reach its destination. This allows different networks to communicate with each other and enables the routing of data between them. A bridge is similar to a switch but operates at the data link layer, not the network layer, so it does not perform the same routing functions as a router. A console is a device used for managing and configuring network devices, but it does not break up broadcast domains or connect networks together.

A one to a group communication known as a ___________________ is used to share data with only those systems that are running the same application or service and thus are part of a specific group of systems.
- Broadcast
- Multicast
- Unicast
- Anycast
Correct Answer

A. Multicast

Explanation

Multicast is the correct answer because it refers to a one-to-a-group communication where data is shared with systems running the same application or service. In multicast, the data is sent to a specific group of systems, allowing them to receive and process the information simultaneously. This method is efficient for distributing data to multiple recipients, reducing network traffic and improving overall performance.
