Employees must use a badge to enter and exit the building. Each time the badge is used, a log entry is created and stored to record who has entered and exited the building. Which of the following best describes what the log entries provide?
Correct Answer: B
The log entries that are created and stored when employees use their badges to enter and exit the building provide accounting. Accounting is a security function that records and tracks user activities and events on a system or network. Accounting can provide evidence of user actions, such as authentication, authorization, access, modification, or deletion of data or resources. Accounting can also provide information for billing, auditing, or reporting purposes. Accounting can be implemented using log files, audit trails, or monitoring tools. Automation is not a security function, but rather a process of using technology to perform tasks or operations without human intervention. Automation can improve productivity, efficiency, accuracy, or reliability of a system or network. Automation can be implemented using scripts, programs, or tools. Authorization is not a security function that records and tracks user activities and events, but rather a security function that grants or denies user access to data or resources based on their identity and permissions. Authorization can ensure that users only access what they are allowed to access on a system or network. Authorization can be implemented using access control lists (ACLs), role-based access control (RBAC), or mandatory access control (MAC). Authentication is not a security function that records and tracks user activities and events, but rather a security function that verifies user identity based on credentials, such as passwords, tokens, biometrics, etc. Authentication can ensure that users are who they claim to be on a system or network. Authentication can be implemented using single-factor authentication (SFA), multi-factor authentication (MFA), or single sign-on (SSO).

Question 52
Which of the following would MOST likely prevent malware sent as compromised file via email from infecting a person's computer?
Correct Answer: B
Patching would be the most likely way to prevent malware sent as a compromised file via email from infecting a person's computer. Patching is the process of applying updates or fixes to software or hardware to improve performance, security, or functionality. Patching can help prevent malware infections by closing the vulnerabilities or flaws that malware exploits to infect systems. Users should regularly patch their operating systems, applications, and antivirus software to protect their computers from malware attacks.

Question 53
Which of the following BEST describes the purpose of a vector in programming?
Correct Answer: A
A vector is a type of data structure that can store a collection of data of the same data type in a dynamic sequence. A vector can grow or shrink in size as data is added or removed from it. A vector would be the best option for storing a collection of data in programming because it can accommodate different amounts of data and allow fast access to any element by using its index number. Repeating a similar operation, capturing user input, and performing mathematical calculations are not purposes of a vector in programming.

Question 54
Which of the following is an advantage of installing an application to the cloud?
Correct Answer: C
Question 55
Which of the following BEST explains the use of float over integer to store monetary values?
Correct Answer: D
Float is a data type that can store decimal or fractional numbers, such as 3.14, 0.5, or -2.75. Float would be the best data type to use for storing monetary values because monetary values often involve decimals, such as $1.99, 0.25,or-5.50. Integer is a data type that can only store whole numbers, such as 1, 0, or -2. Integer would not be suitable for storing monetary values that have decimals. The other options are not data types that can store numerical values.
