220-1102 Exam Dumps - CompTIA A+ Questions and Answers

In a professional work environment, distractions should be minimized, especially when working onsite for a client. The best approach is to put the phone on silent (Option B) to avoid interruptions while remaining professional.

Step aside and answer (Option A): Not recommended as it disrupts work and appears unprofessional.

Text a reply (Option C): While this may seem reasonable, it still causes a distraction.

Ignore the phone and continue working (Option D): While focusing on work is important, completely ignoring calls may not be the best approach. Silent mode ensures work continuity while allowing the technician to check messages later.

Cross-site scripting (XSS) (Option C) allows attackers to inject malicious scripts into web pages viewed by users. When the user visits the compromised site, the script runs in the user's browser, potentially allowing the attacker to steal data or perform unauthorized actions. XSS is a common vulnerability in web applications that allows code execution.

DoS (Option A) disrupts services but doesn't involve executing code on a user's device.

Spoofing (Option B) involves impersonating another device or user but doesn't execute code.

SQL injection (Option D) attacks a database and is unrelated to executing code on the user's computer.

WEP (Wired Equivalent Privacy) is known to be the weakest wireless security protocol due to its vulnerabilities and ease of being compromised.

WEP: The oldest and weakest protocol, susceptible to various attacks and easily cracked.

WPA2: Much stronger security with AES encryption, currently one of the most secure standards.

TKIP: Used with WPA, stronger than WEP but weaker than WPA2 with AES.

AES: Advanced Encryption Standard, used in WPA2 and known for strong security.

EFS (Encrypting File System) is a feature of Windows that provides filesystem-level encryption. It is designed to encrypt files and folders to protect them from unauthorized access, even if an attacker has physical access to the computer.

ext: A filesystem type used primarily in Linux, without native encryption features for Windows.

APFS: Apple's filesystem, used in macOS and iOS.

FAT: A simple filesystem type with no encryption features.

EFS: The correct choice for a Windows user needing to encrypt data at the filesystem level to protect against unauthorized physical access.

The correct answer is B. Scripted Deployment.

Scripted deployment is the most effective method for remotely installing software across multiple devices, including remote employees’ machines.

IT departments commonly use scripting tools like PowerShell, Bash, or batch scripts, along with software deployment solutions like Microsoft SCCM, Intune, or Group Policy.

This method ensures automation, consistency, and remote execution without requiring physical access to each device.

Why Other Options Are Incorrect:

A. Clone – Cloning is used to replicate entire system images but is not practical for deploying individual software programs remotely.

C. In-place – This term typically refers to in-place upgrades or updates to existing software, not new software deployment across multiple machines.

D. Image – Imaging refers to creating a full system image, including the OS and applications. While useful for deploying new computers, it is not ideal for remotely installing software on existing systems.

Objective 3.3 – Given a scenario, use remote access technologies.

Objective 4.2 – Given a scenario, implement cybersecurity best practices.

Restarting services can resolve issues with web applications without requiring a full server reboot, which aligns with the company policy.

Restart services: Likely to resolve issues with the web application by refreshing the necessary services.

Roll back Windows updates: Unnecessary if the issue is with the application services.

Perform a Windows repair: More disruptive and not typically needed for application service issues.

Add RAM to the server: Would require a reboot and is not immediately necessary for troubleshooting application issues.

Badge readers are devices that scan employee or visitor credentials, logging entries and exits from restricted areas. Video surveillance (B) provides a visual record but does not directly control access. Bollards (A) and fences (D) provide physical security but cannot detect or record access events.

Restarting a smartphone is a basic troubleshooting step that often resolves temporary software glitches or minor errors that might be preventing the screen rotation from working correctly. It's a quick and easy step to try before moving on to more complex solutions.

Here's why the other options are not the best first step:

A. Remove the screen protector: While a thick or improperly installed screen protector could potentially interfere with the sensors responsible for screen rotation, it's less likely to be the cause.

B. Update the smartphone’s software: While software updates can fix bugs and improve functionality, they are not always necessary for resolving a screen rotation issue.

D. Replace the smartphone: Replacing the smartphone is a drastic measure and should only be considered if other troubleshooting steps fail.

Troubleshooting Steps:

Restart the smartphone: This often clears temporary software issues.

Check for software updates: If a restart doesn't work, updating the operating system or any relevant apps might resolve the issue.

Calibrate the accelerometer: Some smartphones have a calibration tool for the accelerometer, the sensor that detects orientation. Check the device settings for this option.

Check for hardware issues: If the problem persists, there might be a hardware issue with the accelerometer or other components. In this case, contacting the manufacturer or a repair center might be necessary.

Comprehensive and Detailed In-Depth Explanation:This is a scareware scam that attempts to trick users into installing malicious applications. The best action is to close the website and ignore the pop-up.

B. Replace the smartphone – Incorrect. The phone is likely not compromised; it is just displaying a fake warning.

C. Download and install the application to resolve the issue – Incorrect. Doing so could infect the device with malware.

D. Analyze the smartphone to find the source of the breach – Unnecessary, as there is no real breach.

The camera and microphone on an iPhone activating without user input, especially after allowing applications to be installed outside the normal App Store, is a classic sign of the device being jailbroken. Jailbreaking an iPhone removes many of the built-in security features and restrictions, allowing the installation of apps from third-party sources. These third-party apps can be malicious and can gain unauthorized access to system resources like the camera and microphone.

A. The user connected a counterfeit Lightning cable to the iPhone. While counterfeit cables can be harmful, they typically cause charging or connectivity issues rather than security vulnerabilities that would enable camera and microphone activation without user input.

B. The device is unenrolled from Mobile Device Management. Unenrolling from MDM removes organizational controls but does not directly cause unauthorized camera and microphone activation.

D. The iPhone has an out-of-date operating system. An outdated OS can have vulnerabilities, but the scenario specifically mentions modifications to allow third-party app installations, pointing to jailbreaking as the primary cause.

D. Rootkit – Hides malicious software but does not demand payment.

To configure a new SSD, the technician would use diskmgmt.msc (Disk Management) and diskpart.msc (Diskpart). These tools allow for partitioning, formatting, and managing the SSD. Disk Management is a graphical utility that provides easy access to these tasks, while Diskpart is a command-line tool with advanced features for disk configuration.

Diskmgmt.msc: A GUI-based tool used to manage disk partitions.

Diskpart.msc: A command-line utility used for advanced disk configuration.

Detailed Explanation with Core 2 References:SSH allows for remote access to systems securely and discretely, suitable for verifying patch levels and other administrative tasks. This meets Core 2 objectives on using secure remote access tools (Core 2 Objective 4.9)​.

The ipconfig /all output shows the following:

IPv4 Address............ 192.168.0.74Subnet Mask............. 255.255.255.255Default Gateway......... 192.168.0.1

The issue with the subnet mask being set to 255.255.255.255 is that it specifies a single host subnet, meaning the device cannot communicate with other devices on the network or access the internet. The correct subnet mask for a typical home network should be:

Subnet mask of 255.255.255.0: This allows for communication within the same local network (192.168.0.0/24).

Default gateway 192.168.0.1: Correct, this is the typical address for the router.

IPv4 Address 192.168.0.74: Correct, within the correct subnet range.

Changing the subnet mask to 255.255.255.0 will resolve the connectivity issue.

XFS is a high-performance filesystem created by Silicon Graphics in 1994 and is commonly used by Linux operating systems.
