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

The employee needs to execute a program from the command line, which requires inputting commands into the computer.

The primary device for inputting commands is the keyboard.

Other options like the hard drive, speaker, and printer are not used for inputting commands.

The hard drive is used for data storage.

The speaker outputs sound.

The printer outputs documents.

Therefore, the correct peripheral device for this task is the keyboard.

The goal in this scenario is tosecure the application against malware and advanced persistent threats (APTs). According to the WGU Cybersecurity Architecture and Engineering (KFO1 / D488) course materials:

Firewall policiesare critical forcontrolling accessto applications and network resources.

By implementing astrict firewall policy, you limit access to only trusted and necessary sources, greatly reducing the attack surface available to malware or APT actors.

While antivirus software (Option C) can help detect malware,APT actors often use sophisticated methodsthat bypass traditional antivirus tools.

Encryption (Option A) protectsdata confidentialitybutdoes not preventmalware or APTs from attacking the application.

Strong password policies (Option B) helpwith account securitybutdo not directly addressmalware or APT threats.

Key extract from the WGU D488 Study Guide:

"A strict firewall policy is essential for preventing unauthorized access and mitigating advanced persistent threats. Limiting exposure through segmentation, access control lists, and traffic filtering protects critical assets from external and internal threats."

SQLis a standard language used to communicate with and manage databases. It allows applications to perform operations such as querying, updating, and managing data.

JDBCis an API in Java that enables Java applications to interact with databases. It provides methods for querying and updating data in a database using SQL.

DBMS (Database Management System)is the system software for creating and managing databases but not directly used by applications for database access.

ODBC (Open Database Connectivity)is another standard API but specific to applications in a broader range of languages and platforms.

GUI (Graphical User Interface)is a user interface and not a method for applications to access databases.

Copyrightsare a common legal method used to protect software.

A copyright gives the creator of the software exclusive rights to use and distribute the software.

It protects against unauthorized copying, modification, and distribution of the software.

Software creators can enforce their copyrights to prevent others from infringing on their intellectual property.

Example:Copyright law is often invoked in cases of software piracy.
