The most likely cause of repeated application installation failures on a work-issued laptop is an incorrectly configured Access Control List (ACL). In corporate environments, security policies are designed to limit what standard users can install in order to reduce malware risk, maintain compliance, and ensure system stability. These restrictions are enforced through NTFS permissions, ACLs, and Group Policy settings.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, ACLs define which users or groups have permission to read, write, modify, or execute files and directories. If a user does not have sufficient permissions to write to protected locations such as C:\Program Files, system folders, or specific registry keys, software installers will fail—even if the installer itself is legitimate and intact.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that many organizations intentionally restrict installation privileges to administrators only. This prevents users from installing unauthorized or potentially harmful software. When ACLs are misconfigured or intentionally restrictive, installation attempts may fail repeatedly without clearly stating that permissions are the root cause.

The Mike Meyers / Mark Soper Lab Manual further clarifies that issues like a full browser cache or slow internet speeds typically affect downloads, not the execution of installers. An unformatted hard drive would prevent the operating system from functioning at all, making it irrelevant in this scenario.

Therefore, the repeated installation failure on a work laptop is best explained by incorrectly configured ACLs, making C the correct answer.

Keychainis the built-in macOS utility that manages and stores credentials, including passwords and certificates.

According toQuentin Docter – CompTIA A+ Complete Study Guide:

“Keychain Access in macOS is used for managing and storing passwords securely, similar to credential managers in Windows.”

A Potentially Unwanted Program (PUP) is software that a user may not have knowingly installed. It often gets bundled with legitimate software and installs without full disclosure. PUPs can affect performance, change system settings, or display unwanted ads but are not necessarily malicious like viruses or ransomware.

A. Viruses replicate and spread; they are generally more harmful and not "bundled" in the same way.

B. Ransomware encrypts files for payment and is deliberately malicious.

D. A Trojan disguises itself as legitimate software to perform malicious actions but is not typically pre-bundled by legitimate publishers.

This scenario involves a mismatch in device time settings, which can affect synchronization and authentication across the network. Using a Network Time Protocol (NTP) server ensures all networked devices maintain accurate and synchronized clocks.

From Travis Everett – All-in-One Exam Guide:

“NTP servers keep all devices on a network in sync. This prevents time drift, which can cause authentication issues with domain logins, certificates, and applications.” .

Comprehensive and Detailed Explanation From Exact Extract:

UPS batteries are heavy and often located at the bottom of racks to maintain balance. Safe removal requires the use of correct lifting techniques to avoid injury. OSHA and workplace safety standards emphasize ergonomic handling when dealing with heavy equipment.

A. Fire suppression readiness is important for fire safety but not specifically relevant to battery removal.

C. Antistatic bags are for electronic components, not heavy battery modules.

D. A face mask is not generally necessary unless there is a chemical leak, which is not indicated here.
