NEW QUESTION # 56
In an IPsec implementation using strongSwan, what is the purpose of the Internet Key Exchange (IKE) protocol?
- A. To route IPsec packets across the internet.
- B. To compress IPsec traffic before encryption.
- C. To encrypt the actual data payload of IPsec traffic.
- D. To negotiate and establish the Security Associations (SAs) and cryptographic keys used by IPsec.
Answer: D
Explanation:
The Internet Key Exchange (IKE) protocol is used to negotiate and establish Security Associations (SAs) between two IPsec peers, including agreeing on the cryptographic algorithms to use and securely deriving the shared keys used to protect the actual traffic. IKE operates in two phases: Phase 1 establishes a secure channel between peers (the ISAKMP SA), and Phase
2 negotiates the actual IPsec SAs used to protect data traffic. The data itself is encrypted using the algorithms negotiated via IKE, not by IKE directly.

NEW QUESTION # 65
Which command is used to create an encrypted LUKS-formatted block device?
- A. cryptsetup luksFormat /dev/sdX
- B. cryptsetup open /dev/sdX
- C. mkfs.luks /dev/sdX
- D. dm-crypt --format /dev/sdX
Answer: A
Explanation:
The command "cryptsetup luksFormat /dev/sdX" initializes a block device with the LUKS (Linux Unified Key Setup) header and format, prompting for a passphrase that will be used to protect the master encryption key. Once formatted, the device must be unlocked using "cryptsetup open" (or
"luksOpen"), which creates a mapped device-mapper device that can then be formatted with a standard filesystem and mounted. There is no standard "mkfs.luks" command, since LUKS operates below the filesystem layer.

What is the primary purpose of Online Certificate Status Protocol (OCSP)?
- A. To encrypt data in transit between a client and server.
- B. To allow a client to check the revocation status of a specific X.509 certificate in real time.
- C. To distribute the full Certificate Revocation List to all clients.
- D. To generate new X.509 certificates automatically.
Answer: B
Explanation:
The Online Certificate Status Protocol (OCSP) allows a client to query a certificate authority's OCSP responder to check the real-time revocation status of a specific certificate, rather than downloading and parsing an entire Certificate Revocation List (CRL). OCSP responses are typically much smaller and faster to process than CRLs, especially as the number of revoked certificates grows, though OCSP does introduce a dependency on the availability of the OCSP responder at validation time, which OCSP stapling helps address.
