 Date and time is the most likely cause of the issue. The date and time settings on a workstation affect the validity of the certificates used by websites to establish secure connections. If the date and time are incorrect, the workstation may not recognize the certificate as valid and display an invalid certificate error. Other workstations on the same local network may not have this issue if their date and time are correct. User access control, UEFI boot mode, and log-on times are not likely causes of the issue. User access control is a feature that prevents unauthorized changes to the system by prompting for confirmation or credentials. UEFI boot mode is a firmware interface that controls the boot process of the workstation. Log-on times are settings that restrict when a user can log in to the workstation. None of these factors affect the validity of the certificates used by websites. References:

The best course of action for the technician is to restore the defaults and reimage the corporate OS on the device. This will remove the jailbreak and any unauthorized or malicious apps that may have been installed on the device, as well as restore the security features and policies that the company has set for its devices. This will also ensure that the device can receive the latest updates and patches from the manufacturer and the company, and prevent any data leakage or compromise from the device.

Jailbreaking is a process of bypassing the built-in security features of a device to install software other than what the manufacturer has made available for that device1. Jailbreaking allows the device owner to gain full access to the root of the operating system and access all the features1. However, jailbreaking also exposes the device to various risks, such as:

The loss of warranty from the device manufacturers2.

Inability to update software until a jailbroken version becomes available2.

Increased security vulnerabilities32.

Decreased battery life2.

Increased volatility of the device2.

Some of the signs of a jailbroken device are:

A high number of ads, which may indicate the presence of adware or spyware on the device3.

Receiving data-usage limit notifications, which may indicate the device is sending or receiving data in the background without the user’s knowledge or consent3.

Experiencing slow response, which may indicate the device is running unauthorized or malicious apps that consume resources or interfere with the normal functioning of the device3.

Finding apps or icons that the user did not install or recognize, such as Cydia, which is a storefront for jailbroken iOS devices1.

The other options are not sufficient or appropriate for dealing with a jailbroken device. Running an antivirus and enabling encryption may not detect or remove all the threats or vulnerabilities that the jailbreak has introduced, and may not restore the device to its original state or functionality. Backing up the files and doing a system restore may not erase the jailbreak or the unauthorized apps, and may also backup the infected or compromised files. Undoing the jailbreak and enabling an antivirus may not be possible or effective, as the jailbreak may prevent the device from updating or installing security software, and may also leave traces of the jailbreak or the unauthorized apps on the device.

Some electronic items require special e-waste recycling because they contain hazardous materials that can harm the environment and human health if disposed of improperly12. Laptop batteries and CRT monitors are examples of such items.

Laptop batteries are usually made of lithium-ion or nickel-metal hydride, which are both toxic and flammable substances34. If laptop batteries are thrown in the trash, they can leak, catch fire, or explode, causing pollution and injuries5 . Therefore, laptop batteries should be recycled at authorized collection centers or through manufacturer take-back programs .

CRT monitors are old types of display devices that use cathode ray tubes, which are glass tubes that emit electrons to create images on the screen . CRT monitors contain lead, mercury, cadmium, and phosphor, which are all harmful metals that can contaminate the soil, water, and air if dumped in landfills . Therefore, CRT monitors should be recycled at certified e-waste facilities or through retailer or manufacturer trade-in programs .

Chain of custody documentation is a record of the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. It is important to maintain a chain of custody to ensure the integrity and authenticity of the evidence, and to prevent tampering or contamination. If a laptop that was in the evidence room of a police station is missing, the best reason to refer to chain of custody documentation is to determine which party had the machine and when. This can help to identify the possible suspects, locate the missing laptop, and verify if the evidence on the laptop was compromised or not

WPA2 is the only protocol among the options that supports fast roaming between networks. Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), enables a client device to roam quickly in environments implementing WPA2 Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another1. WEP, WPA, LEAP, and PEAP do not support fast roaming and require the client device to perform the full authentication process every time it roams, which can cause delays and interruptions in the network service.

Screen timeout is the setting that determines how long the screen stays on after the user stops interacting with the phone. Screen brightness is the setting that determines how much light the screen emits. Both of these settings affect the battery life of the phone, as keeping the screen on longer and brighter consumes more power than turning it off sooner and dimmer. A technician should check these settings first to troubleshoot the issue of low battery life and adjust them accordingly. Screen resolution, screen zoom, screen damage, and screen motion smoothness are not settings that directly affect the battery life or the screen staying on for a long time.

Disk Cleanup is a tool that can free up some space on a system drive that is nearly full. It can delete temporary files, cached files, recycle bin files, old system files and other unnecessary data. Resource Monitor is a tool that shows the network activity of each process on a Windows machine. Disk Defragment is a tool that optimizes the performance of a hard drive by rearranging the data into contiguous blocks. Disk Management is a tool that allows creating, formatting, resizing and deleting partitions on a hard drive.

MSRA (Microsoft Remote Assistance) is a remote access technology that allows a technician to establish a session with a user who has a Windows workstation. The session allows for simultaneous viewing of the workstation by both the user and technician, as well as remote control and file transfer capabilities. RDP (remote desktop protocol) is another remote access technology, but it does not allow simultaneous viewing by default. VPN (virtual private network) and SSH (secure shell) are protocols that create secure tunnels between two devices over the internet, but they do not allow remote access sessions.

Educating the end user is the best way to prevent future infections by viruses or other malware. The technician should teach the user how to avoid risky behaviors, such as opening suspicious attachments, clicking on unknown links, downloading untrusted software, etc. Disabling System Restore, installing the latest OS patches and performing a clean installation are possible ways to remove existing infections, but they do not prevent future ones.

The best way to resolve the issue is to move factory applications to external memory. This will free up some space on the phone’s internal storage, which is required for updating the phone. To do this, you can follow these steps1:

Insert a microSD card into your phone if you don’t have one already.

Go to Settings > Apps and tap on the app you want to move.

Tap on Storage and then on Change.

Select the SD card option and tap on Move.

You may need to repeat this process for multiple apps until you have enough space to update your phone. Alternatively, you can also clear the cache and data of some apps, or uninstall the apps that you don’t use frequently. You can find more information on how to fix insufficient storage error on your phone in these articles234. I hope this helps.

An equipment lock is a physical security device that attaches a laptop to a fixed object, such as a desk or a table, with a cable and a lock. This can prevent the laptop from being stolen by unauthorized persons. Encryption, LoJack, multifactor authentication and bollards are other security measures, but they do not physically prevent theft.

Cryptomining malware is a type of malicious program that uses the CPU resources of a compromised server to generate cryptocurrency, such as Bitcoin or Ethereum. It can cause extremely high CPU utilization and network traffic to the IP address of the cryptocurrency service. Keylogger, ransomware and boot sector virus are other types of malware, but they do not cause the same symptoms as cryptomining malware.

 Instructing the user to disconnect the Wi-Fi is the first action the technician should take if they suspect a rogue access point. A rogue access point is an unauthorized wireless network that could be used to intercept or manipulate network traffic, compromise security, or launch attacks. Disconnecting the Wi-Fi would prevent further exposure or damage to the user’s device or data. Restarting the wireless adapter, launching the browser, or running the antivirus software are possible actions to take after disconnecting the Wi-Fi, but they are not as urgent or effective as the first step. References:

The correct answer is C. Choose what closing the lid does. This option allows you to configure how the laptop behaves when you close the lid, such as whether it goes to sleep, hibernates, shuts down, or does nothing. To access this option, you can follow these steps :

Go to Settings > System > Power & sleep.

Click on Additional power settings on the right side.

Click on Choose what closing the lid does on the left side.

Under When I close the lid, select Do nothing for both On battery and Plugged in.

Click on Save changes.

This will prevent the laptop from going to sleep when you close the lid while it is connected to the docking station and the external monitor.

Hibernate, sleep/suspend, and turn on fast startup are not the options that should be configured to fix the issue. Hibernate and sleep/suspend are both power-saving modes that allow you to resume your work without losing any data. However, they also turn off the display and other components of the laptop, which means you will not be able to use the external monitor when the laptop is closed. Turn on fast startup is a feature that reduces the boot time of Windows by saving some system information to a file when you shut down. It does not affect how the laptop behaves when you close the lid .

Disk Defragment is a tool that can be used to improve the performance of a hard disk drive (HDD). HDDs store data in sectors and clusters on spinning platters. Over time, as data is written, deleted, and moved, the data may become fragmented, meaning that it is spread across different locations on the disk. This causes the HDD to take longer to access and load data, resulting in slower performance. Disk Defragment consolidates the fragmented data and rearranges it in a contiguous manner, which reduces the seek time and increases the speed of the HDD. Disk Management, Disk Cleanup, and Device Manager are not tools that can alleviate the issue of slow HDD performance.
