WGU Updated Cybersecurity-Architecture-and-Engineering Exam Questions and Answers by obie

AES (Advanced Encryption Standard)is a symmetric block cipher approved by NIST for protecting sensitive data, includingelectronic protected health information (ePHI). It is the recommended encryption method underHIPAA compliance guidelines.

NIST FIPS 197 (Advanced Encryption Standard - AES):

“AES is a symmetric cipher used to protect sensitive electronic data and is approved for use in securing government and healthcare systems.”

WEP is outdated, SMTP is a protocol for email, and RSA is better suited for key exchange, not bulk data encryption.

The correct answer is A — Implementation of real-time transaction monitoring.

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), real-time transaction monitoring detects and alerts suspicious banking activities immediately, helping prevent credit card fraud and securing the online banking system during deployment and use.

Strict firewall policies (B) help secure access but are not transaction-specific. Disabling email (C) and performing backups (D) are good practices but do not directly address fraud prevention.

Reference Extract from Study Guide:

"Real-time transaction monitoring identifies suspicious activities, providing immediate detection and prevention of fraudulent transactions in online banking systems."

=============================================

The correct answer is B — Advanced Encryption Standard (AES).

According to WGU Cybersecurity Architecture and Engineering (KFO1 / D488), AES is a widely adopted symmetric encryption standard that ensures the confidentiality and integrity of sensitive data, including patient health information, which HIPAA mandates to protect. AES is considered highly secure and efficient for encrypting stored or transmitted healthcare data.

WEP (A) is outdated and insecure. SMTP (C) is a protocol for sending emails, not encryption. RSA (D) is an asymmetric encryption method typically used for key exchanges, not bulk data encryption.

Reference Extract from Study Guide:

"Advanced Encryption Standard (AES) is recommended for encrypting sensitive healthcare data, providing strong protection for confidentiality and integrity in HIPAA-regulated environments."

The SQL statement provided is:

SELECT*FROMCustomersWHEREState ='Arizona';

SELECT *indicates that all columns from the table should be selected.

FROM Customersspecifies the table from which to retrieve the data.

WHERE State = 'Arizona'filters the results to include only those records where the State column has the value 'Arizona'.

Therefore, the statement returns all records from the Customers table that are located in Arizona.
