CCNA1 Lesson 14 Transport Layer

Multiple Choice

Why is the transport layer important in computer networks?

• It manages end-to-end communication between devices

• It provides physical connections between devices

• It encrypts all network data

• It stores user data

Multiple Choice

Which protocols are included in the transport layer?

• TCP and UDP

• IP and ICMP

• FTP and HTTP

• ARP and RARP

Fill in the Blanks

The transport layer divides data into smaller blocks called

or datagrams.

Open Ended

What is the purpose of adding header information at the transport layer?

Multiple Choice

Which of the following are responsibilities of the transport layer?

• Tracking individual conversations

• Segmenting data and reassembling segments

• Adding header information

• All of the above

Multiple Choice

Which port number is typically used for electronic mail (email) applications?

• 110

• 80

• 531

• 25

Multiple Choice

Which of the following is a key responsibility of the transport layer as described in the context of conversation multiplexing?

• Providing physical connections between devices

• Allowing multiple applications to use the network at the same time

• Assigning IP addresses to devices

• Encrypting data before transmission

Multiple Choice

Which protocols are included in the transport layer?

• TCP and UDP

• IP and DNS

• FTP and HTTP

• SMTP and TFTP

Fill in the Blanks

TCP divides data into

before transmission to ensure reliable delivery.

Multiple Select

Select all the features provided by TCP as a transport layer protocol. (Choose 3)

• Establishes a session

• Ensures reliable delivery

• Provides reverse-order delivery

• Supports flow control

Multiple Select

Which of the following are features of UDP? (Choose 3)

• No session establishment

• Segments lost are not resent

• Data is reconstructed in the order received

• Requires session establishment

Fill in the Blanks

A 16-bit field used for error checking of the datagram header and data in UDP is called

.
