A security team wants to implement compliance controls that only permits the installation of company-approved software on user laptops. Which of the following should the IT department deploy?
Correct Answer:C
Mobile Device Management (MDM) allows IT departments to enforce compliance controls, such as restricting the installation of unapproved software, on laptops and mobile devices. Why Not A (EDR): Endpoint Detection and Response focuses on detecting and mitigating security threats, not compliance controls.
Why Not B (VPN): Virtual Private Networks provide secure connections but do not enforce software installation policies.
Why Not D (SaaS): Software as a Service refers to software delivery models and does not enforce compliance controls.

Which of the following networking devices will most likely need to be installed in between the ISP running DOCSIS and the LAN in a SOHO environment?
Correct Answer:C
Comprehensive and Detailed Step-by-Step Explanation:
To determine the correct device, we need to understand how a DOCSIS (Data Over Cable Service Interface Specification) network functions in a Small Office/Home Office (SOHO) environment:
* C. Cable Modem:
A cable modem is required to convert the signal provided by the ISP (Internet Service Provider) over a DOCSIS network into a format that is usable by the local area network (LAN).
DOCSIS is a standard for high-speed internet over cable television infrastructure, and the cable modem acts as the gateway between the ISP's coaxial network and the LAN. Without the cable modem, devices in the LAN would not be able to access the internet. Reference: CompTIA A+ Core 1 Exam Objectives (220-1201), Domain 2.2 – Compare and contrast Internet connection types, network types, and their features.
Incorrect Options:
* A. Switch:
A switch is used to connect multiple devices within the LAN. It does not connect the LAN to the ISP's DOCSIS network.
* B. Firewall:
While firewalls provide security by managing inbound and outbound traffic, they do not serve as the interface between the ISP and LAN.
* D. Router:
A router directs traffic between different networks (e.g., between a LAN and the internet). However, in a DOCSIS network, the cable modem is the device that first connects to the ISP. Many modern cable modems also include built-in routers, but the modem is the primary device needed.
* E. Access Point:
An access point provides wireless connectivity within the LAN. It does not connect directly to the ISP or handle DOCSIS signals.
Key Takeaway:The correct device required to interface between the ISP's DOCSIS network and the SOHO LAN is the cable modem.

A management team is concerned about enterprise devices that do not have any controls in place. Which of the following should an administrator implement to address this concern?
Correct Answer:A
Mobile Device Management (MDM) enables administrators to enforce controls on enterprise devices, such as restricting apps, ensuring compliance, and remotely managing security policies.
Why Not B (MFA): Multi-Factor Authentication secures user access but does not control device configurations.
Why Not C (VPN): VPN secures communication but does not enforce device controls. Why Not D (SSL): SSL secures data in transit but does not provide device management. CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.7, device management concepts.

A user is experiencing multiple issues with an in-place upgrade of a laptop's operating system. The built-in camera is unresponsive, and the user is unable to pair the device with any Bluetooth accessories. Which of the following ate most likely causing three issues? (Select two).
Correct Answer:CE
Outdated drivers: Device functionality issues after an OS upgrade are often caused by incompatible or outdated drivers.
Disabled settings: Some features may be disabled during the upgrade process, requiring re-enablement.
Why Not A (Incorrect configuration): This is unlikely given the issues arose only after the upgrade.
Why Not B (OS and device incompatibility): Upgrades check for compatibility before installation.
Why Not D (Full storage): Storage issues typically prevent installation, not device functionality.
Why Not F (Corrupted registry entries): While possible, this is less common than the selected answers.

Which of the following devices is designed to monitor and filter incoming and outgoing network traffic?
Correct Answer:C
A firewall monitors and filters incoming and outgoing network traffic based on security rules, protecting the network from unauthorized access and threats.
Why Not A (Switch): A switch connects devices within a network but does not monitor or filter traffic.
Why Not B (Access point): An access point provides Wi-Fi connectivity but does not filter traffic.
Why Not D (Hub): A hub simply broadcasts data to all connected devices without filtering traffic.
