NET+ Quiz Part 7

Which two underlying protocols does IPSec rely on?

• TCP and UDP

• AH and ESP

• HTTP and HTTPS

• FTP and SFTP

Answer explanation

IPSec relies on the Authentication Header (AH) and Encapsulating Security Payload (ESP) protocols for securing communications.

What does AH provide in IPSec?

• Encryption services

• Authentication services

• Data compression

• File transfer services

Answer explanation

AH in IPSec provides Authentication services, ensuring the identity of communicating parties before establishing a secure connection.

What does ESP provide in IPSec?

• Encryption services

• Authentication services

• Data compression

• File transfer services

Answer explanation

ESP provides Encryption services in IPSec, ensuring data confidentiality and security during transmission.

Which organization created IPSec?

• IEEE

• IETF

• ISO

• W3C

Answer explanation

The correct organization that created IPSec is IETF (Internet Engineering Task Force).

Which of the following is NOT a key security service provided by IPSec?

• Data verification

• Protection from data tampering

• Private transactions

• Data compression

Answer explanation

Data compression is NOT a key security service provided by IPSec. The other options, such as data verification, protection from data tampering, and private transactions, are key security services offered by IPSec.

At which layer of the OSI model does IPSec operate?

• Application layer

• Transport layer

• Network layer

• Data link layer

Answer explanation

IPSec operates at the Network layer of the OSI model, providing security services for IP packets at this level.

What is the primary function of Generic Routing Encapsulation (GRE)?

• To provide encryption services

• To wrap data and securely send it across VPNs

• To verify data integrity

• To manage file transfers

Answer explanation

The primary function of Generic Routing Encapsulation (GRE) is to wrap data and securely send it across VPNs, ensuring secure transmission of data.

What does File Transfer Protocol (FTP) provide?

• Encryption services

• Data verification

• Uploading and downloading of files

• Network routing

Answer explanation

FTP provides the uploading and downloading of files, allowing users to transfer files between a client and a server.

What does FTP enable you to do on an FTP server?

• View the contents of folders, rename and delete files and directories

• Only view the contents of folders

• Only rename files

• Only delete files

Answer explanation

FTP enables you to view the contents of folders, rename, and delete files and directories on an FTP server.

Which protocol does FTP use to guarantee the delivery of packets?

• UDP

• TCP

• HTTP

• SMTP

Answer explanation

FTP uses TCP to guarantee the delivery of packets, as TCP provides reliable, connection-oriented communication ensuring data packets are delivered in order and without errors.
