At large events such as music festivals, cellular towers may become congested due to the high volume of users attempting to connect simultaneously. This congestion causes slow or failed data connections, which explains the email application being unable to sync or connect. This is a common real-world mobile connectivity issue in crowded areas.

A. Lack of storage would prevent saving attachments, not prevent connection attempts.

B. Company firewalls usually don’t affect mobile access unless specific device restrictions are enforced.

D. Organizers do not have the ability to block the internet signal; only carriers manage mobile bandwidth.

Comprehensive and Detailed Explanation From Exact Extract:

Mobile OS updates can sometimes cause compatibility issues with specific apps, including corporate email clients. The most likely resolution is to check for and apply an update to the affected application, especially if it hasn’t been updated to support the latest OS version.

B. Registering with MDM might be required for access but wouldn’t address app crashes due to incompatibility.

C. A third-party client might help, but it’s not the best first step if the default app is expected to work.

D. Clearing the cache can help resolve some minor issues, but updating the app directly addresses compatibility concerns.

Comprehensive and Detailed Explanation From Exact Extract:

The amount of installed RAM is the key factor in determining whether a 64-bit OS is needed. A 32-bit operating system cannot effectively address more than 4GB of RAM. Since this system has 16GB of RAM, a 64-bit OS is required to utilize the full memory.

B. An Intel i7 CPU supports both 32-bit and 64-bit OS installations, so it alone doesn’t determine the need.

C. HDD size does not influence OS architecture selection.

D. Ethernet speed is a network consideration and not related to OS architecture.

Comprehensive and Detailed Explanation From Exact Extract:

To prevent external access, the technician should avoid exposing the surveillance system’s port to the public internet. Port mapping (also known as port forwarding) is the method used to control which internal devices and ports are accessible from the outside. By not configuring port forwarding for the device, external login attempts are effectively blocked.

B. Subnetting organizes IP addresses but doesn't directly restrict access.

C. A static IP ensures consistent addressing but does not secure access.

D. Content filtering is used to restrict web content, not to block access to a web interface.

Comprehensive and Detailed Explanation From Exact Extract:

User offboarding involves disabling the departing user's access to company systems and facilities. Two key tasks typically include:

Deactivating physical access credentials (e.g., key fobs or badges) to prevent unauthorized entry (B).

Suspending or disabling the user’s email account to prevent future use and to retain business communications (D).

A. Quarantining a hard drive is not standard unless malware or legal issues are involved.

C. Purging PII must follow legal retention policies; it's not typically an immediate offboarding task.

E. Disabling network ports may be relevant in some cases but is not a standard offboarding step.

F. Blocking MAC addresses is not typical unless the device is considered a security threat.

Comprehensive and Detailed Explanation From Exact Extract:

Virtualization settings are typically found within the BIOS/UEFI firmware configuration. To prevent unauthorized users from changing these settings, the technician should set a BIOS password. This ensures only administrators with the password can access or modify BIOS settings, including virtualization support.

B. The guest account is a user-level feature in Windows and doesn’t control BIOS access.

C. A screen lock prevents casual access to the desktop but doesn’t protect firmware settings.

D. AutoRun controls how media and devices behave when inserted — unrelated to BIOS security.

Comprehensive and Detailed Explanation From Exact Extract:

The su (substitute user) command is used in Linux to switch to another user account, most commonly to escalate privileges by switching to the root (administrator) account. It allows administrative tasks to be performed in a terminal session.

A. runas is a Windows command for executing a program under another user's context.

B. cmcl is not a valid Linux or administrative command.

C. net user is a Windows command for managing local user accounts.

Comprehensive and Detailed Explanation From Exact Extract:

A synthetic full backup combines the last full backup with subsequent incremental backups to create a new full backup without re-reading data from the source system. This method significantly reduces the backup window and network impact. It is especially useful when traditional full backups are too time-consuming.

A. Changing the backup window only shifts timing, not duration.

B. Incremental weekly backups would lack a proper full recovery point and aren't ideal alone.

C. Storage space isn't the bottleneck in backup speed—it’s read/write operations and network load.

Comprehensive and Detailed Explanation From Exact Extract:

Since the issue has recurred after a temporary fix, it is likely a deeper or persistent configuration or server issue. Escalating the ticket to the next tier of support (e.g., network or system administrator) ensures further investigation and permanent resolution. Escalation is part of the standard support protocol when issues reoccur despite initial troubleshooting.

A. Rechecking remotely may confirm the issue, but doesn’t resolve it long term.

B. Providing documentation helps the user but doesn’t solve the root cause.

D. Keeping the ticket open is passive and doesn’t address the recurring issue.

Comprehensive and Detailed Explanation From Exact Extract:

The ext4 (Fourth Extended Filesystem) is the most widely used default filesystem in modern Linux distributions. It is designed for high performance, scalability, and reliability, and is supported by all mainstream Linux kernels.

A. exFAT is used for cross-platform external drives, not native Linux systems.

B. APFS is Apple's proprietary filesystem for macOS and iOS.

D. NTFS is the default filesystem for Windows, not Linux.

Comprehensive and Detailed Explanation From Exact Extract:

Multi-Factor Authentication (MFA) requires at least two different types of authentication factors:

Something you know (e.g., password or PIN)

Something you have (e.g., smartphone or hardware token)

Something you are (e.g., fingerprint or facial recognition)

Option A, sending a code to the user’s phone, is an example of "something you have" — a physical device that receives a one-time passcode. Combined with a password, this forms a proper MFA implementation.

B. Date of birth is another knowledge-based factor (like a password), not a second factor type.

C. Solving a math problem is not a recognized authentication factor.

D. A PIN is also "something you know" and does not count as a distinct MFA factor when paired with a password.

Comprehensive and Detailed Explanation From Exact Extract:

PXE (Preboot Execution Environment) allows workstations to boot over the network and download an OS image from a server. It is ideal for automating mass deployments using baseline images across many machines without the need for physical media.

A. An ISO is a disk image file but requires mounting or physical media.

B. Secure Boot is a security feature, not a method of deploying OS images.

C. USB requires manual installation and is not suitable for automated deployment at scale.

The correct answer isVNC (Virtual Network Computing). VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It is platform-independent and widely supported on Linux, which makes it ideal for providinginteractive remote support for a Linux-based operating system. It allows the technician not only to view the remote desktop session but also tocontrol it, fulfilling the need to see and interact with the user’s session.

A. VPN(Virtual Private Network) creates a secure tunnel to a network but doesnot provide desktop sharing or session controlby itself.

C. SSH(Secure Shell) provides secure command-line access to Unix/Linux systems but does not offergraphical desktop interaction, which is a requirement in this case.

D. RDP(Remote Desktop Protocol) is primarily a Microsoft protocol, and although it can be made to work on Linux, it isnot natively supported on legacy Linux systems, and thusless suitablethan VNC in this scenario.

Comprehensive and Detailed Explanation From Exact Extract:

An "OS Not Found" error typically indicates that the computer is attempting to boot from a drive that doesn't contain a valid operating system or bootable partition. The presence of a USB drive might be confusing the boot order. Therefore, the first step a technician should take is to verify and adjust the boot sequence in the system’s firmware (BIOS or UEFI). It's possible that the USB drive is being prioritized over the internal hard drive, which may cause the system to miss the OS entirely.

A. Running data recovery tools is premature before confirming boot order.

B. Repartitioning the disk would destroy existing data—this should not be done until confirmed the OS is actually missing.

D. Switching between UEFI and BIOS (legacy mode) might help in rare cases, but it is not the first step in standard OS boot issue troubleshooting.
