Solution: pam_cracklib

Answer: B


NEW QUESTION # 52
What is the purpose of a LUKS key slot?

Answer: C

Explanation:
LUKS supports multiple key slots (typically up to eight), each of which stores an independently encrypted copy of the volume's master encryption key, protected by a different passphrase or keyfile. This allows multiple users or unlock methods to access the same encrypted volume without sharing a single passphrase, and allows a passphrase to be changed or revoked (by clearing its key slot) without needing to re-encrypt the entire underlying data, since the actual master key used to encrypt the data itself never changes.


NEW QUESTION # 53

X509v3 Basic Constraints: critical CA:TRUE, pathlen:0
Which of the following statements are true regarding the certificate? (Choose THREE correct answers.)

Answer: B,C,E


NEW QUESTION # 54
Which OpenVPN configuration directive specifies that the tunnel should operate at Layer 3, routing IP packets rather than bridging Ethernet frames?

Answer: C

Explanation:
The "dev tun" directive configures OpenVPN to create a Layer 3 (routed) tunnel interface, which encapsulates and routes IP packets between the client and server. In contrast, "dev tap" creates a Layer 2 (bridged) tunnel interface that carries entire Ethernet frames, allowing broadcast traffic and non-IP protocols to pass through the tunnel, which is useful for certain bridging scenarios but generally has more overhead than a routed tun-based configuration.
