Questions 1–10 of 10

1. What is the scrambled, unreadable format produced by encryption called?
Question 1A. PlaintextB. CipherTextC. HashD. ChecksumE. Token
2. Which of these is an example of data-at-rest?
Question 2A. Data moving from a laptop to a thumb driveB. Data shown to a user in a BI dashboardC. Data sitting in a database, data warehouse or data lakeD. Data travelling through the InternetE. Data displayed on a web portal such as LinkedIn
3. What is data-in-transit?
Question 3A. Data stored in an in-memory platformB. Data moving between devices, within private networks, through the Internet or to a thumb driveC. Data exposed to end users in a BI toolD. Data that has been decrypted for analysisE. Data archived on tape
4. Which of these is an example of data-in-use?
Question 4A. Data in a Snowflake warehouseB. Data travelling over a private networkC. Data exposed to end users in a BI tool or on a website such as FacebookD. Data on a backup driveE. Data waiting in a message queue
5. What characterises symmetric (secret key) encryption?
Question 5A. It uses two linked keys, one public and one privateB. It uses one key to both encode and decode the informationC. It requires no key at allD. It is used only for data-in-transitE. It is best suited to very large data sets
6. In asymmetric (public-key) cryptography, which key is kept private?
Question 6A. The encryption keyB. The decryption keyC. Both keysD. Neither keyE. The session key
7. Which of the following is NOT listed among the data encryption standards?
Question 7A. Triple DES (3DES)B. BlowfishC. Elliptic Curve Cryptography (ECC)D. Base64E. Advanced Encryption Standard (AES)
8. What does decryption do?
Question 8A. Generates a new key for each messageB. Compresses the CipherText for storageC. Brings the data back to its original format using the key generated at encryptionD. Classifies data into risk groupsE. Masks sensitive columns before display
9. What does encryption key lifecycle management refer to?
Question 9A. Rotating passwords for end users every ninety daysB. Centrally managing keys from the time they are created until they are deactivated and terminatedC. Distributing public keys through a websiteD. Storing keys inside the encrypted database itselfE. Choosing between symmetric and asymmetric algorithms
10. Why is SSL decryption technology recommended as part of implementing encryption?
Question 10A. Because it replaces the need for key managementB. Because it makes symmetric keys unnecessaryC. Because encryption alone is not enough and SSL technology gives insight into sensitive data at points of egress and ingressD. Because it speeds up database queriesE. Because regulators forbid other standards
