What protocol is used with L2TP to encrypt data?
- A.
IPSec
- B.
MS-CHAP
- C.
MS-CHAPv2
- D.
MPPE
Correct Answer
A. IPSecExplanation
IPSec is used with L2TP (Layer 2 Tunneling Protocol) to encrypt data. L2TP provides the tunneling mechanism for establishing virtual private networks (VPNs) and IPSec is the protocol that adds security to the VPN by encrypting the data that is being transmitted. IPSec ensures the confidentiality, integrity, and authenticity of the data by encrypting it and providing secure communication over the internet.Rate this question:
-
- 9.
Which component of IPSec is generates the encryption and authentication keys?
- A.
SA
- B.
AH
- C.
ESP
- D.
MPPE
Correct Answer
A. SAExplanation
SA stands for Security Association, which is responsible for generating the encryption and authentication keys in IPSec. The SA defines the security parameters and the algorithms to be used for securing the communication between two entities. It establishes a secure channel between the sender and receiver, ensuring confidentiality, integrity, and authentication of the data. The SA generates the necessary keys that are used for encryption and authentication of the IP packets.Rate this question:

Which IPsec component provides connectionless integrity and data authentication but does not provide confidentiality?
- A.
SA
- B.
AH
- C.
ESP
- D.
MPPE
Correct Answer
B. AHExplanation
AH (Authentication Header) provides connectionless integrity and data authentication but does not provide confidentiality. It ensures that the data has not been tampered with during transmission by adding a header that includes a cryptographic checksum. However, AH does not encrypt the data, so it does not provide confidentiality or privacy.Rate this question:
-

Which IPsec component includes the most security, including confidentiality?
- A.
SA
- B.
AH
- C.
ESP
- D.
MPPE
Correct Answer
C. ESPExplanation
ESP (Encapsulating Security Payload) is the correct answer because it provides the most security, including confidentiality. ESP encrypts the entire IP packet, including the payload, to ensure that the data remains confidential and cannot be intercepted or read by unauthorized parties. It also provides authentication and integrity checks to ensure that the data has not been tampered with during transmission. AH (Authentication Header) only provides authentication and integrity checks but does not encrypt the payload, while SA (Security Association) and MPPE (Microsoft Point-to-Point Encryption) do not provide the same level of security and confidentiality as ESP.Rate this question:
