Question6Max. score: 1.00You need to encrypt and send a large amount of data. Which of the followingwould be the best option?Asymmetric encryptionSymmetric EncryptionHashing AlgorithmPKI

Question10Max. score: 1.00Imagine that you are an attacker. Which would be most desirable when attempting tocompromise encrypted data?the Algorithma weak KeyCaptured Traffica Block Cipher

Question5Max. score: 2.00For certain applications, especially those involving direct communication between clients, you aim to ensure that data is encrypted from its point of origin to its destination, known as end-to-end encryption. The ideal encryption method must ensure intermediaries cannot access plaintext information, protect data confidentiality and integrity across the transmission path, and be commonly used in messaging apps, email, and other forms of direct communication to ensure reasonable overhead. Which of the following encryption algorithms best meets your objectives?AES with RSAECC with Diffie-HellmanRSA with HMACPGP/GPG

Question9Max. score: 2.00Next, you turn your attention to information that travels over the network, both internally and externally. Your goal is to select an encryption algorithm that ensures data integrity and confidentiality without causing significant latency. The selected method of encryption should be known for its efficiency in securing online communications, capable of encrypting data quickly to minimise latency, and usable in SSL/TLS protocols for secure web browsing, email, and VPNs. Which of the following encryption algorithms best meets your requirements?AESRSAHMACDiffie-Hellman

You share text files with colleagues using RSA key pairs. Your colleague suggests creating hash digests of text files you share. What will this accomplish?1 pointIt will create an extra public key.It will allow you to verify if the text files have been modified. It will create an extra private key.It will encrypt the public key file.

Question10Max. score: 2.00As a CISO, you understand that protecting data being processed or actively accessed by applications is equally crucial, especially for sensitive operations like customer transactions. Your challenge is to implement an encryption method that protects data during computation without degrading performance. The encryption method must allow encrypted data to be processed without decryption, support operations on encrypted data to ensure privacy and integrity during processing, and be ideal for environments where sensitive data is frequently accessed and processed.
