WGU Introduction to Cryptography HNO1 Introduction-to-Cryptography Prüfungsfragen mit Lösungen (Q79-Q84):

79. Frage
(An administrator has configured a Virtual Private Network (VPN) connection utilizing IPsec transport mode with Encapsulating Security Payload (ESP) between a server in the corporate office and a client computer in the remote office. In which situation can the packet content be inspected?)

A. On devices at headquarters and offsite before being sent and after being received
B. Only in the headquarters' network while data is in transit
C. In the headquarters' and offsite location's networks after the data has been sent
D. Only in the offsite location's network while data is in transit

Antwort: A

Begründung:
With IPsec ESP in transport mode, the payload of the original IP packet (typically the transport-layer segment and higher) is encrypted and integrity-protected between the two endpoints-here, the corporate server and the remote client. Because encryption is applied by the sending endpoint and removed only by the receiving endpoint, intermediate routers, switches, and monitoring devices in either network cannot view the protected payload while it is in transit. They may see outer IP headers and certain metadata needed for routing, but not the encrypted content protected by ESP. As a result, the packet's contents are inspectable only at the endpoints: before encryption on the sender (plaintext exists in memory/stack before IPsec processing) and after decryption on the receiver (plaintext is restored for the application). This is true whether the traffic traverses internal networks or the Internet; the cryptographic boundary is between the endpoints participating in the IPsec SA.
Therefore, inspection of the actual content is possible only on the devices at headquarters and offsite, before sending and after receiving, not by in-transit networks.

80. Frage
(Which attack may take the longest amount of time to achieve success?)

A. Birthday
B. Brute-force
C. Dictionary
D. Rainbow table

Antwort: B

Begründung:
A brute-force attack exhaustively tries every possible key or password candidate until the correct one is found. Because it explores the full search space (or a very large portion of it), brute force is often the slowest method, especially when strong keys, long passwords, rate limits, and slow password hashing (bcrypt/Argon2) are used. By contrast, a dictionary attack reduces work by trying only common or likely passwords, often succeeding quickly against weak human-chosen secrets. Rainbow table attacks shift work into precomputation; once a table exists, lookup can be faster than brute-force-though salt and modern hashing defeat them. Birthday attacks are about finding collisions, not necessarily recovering a specific secret, and their expected work is about 2
