An Android user contacts the help desk because a company smartphone failed to complete a tethered OS update A technician determines there are no error messages on the device Which of the following should the technician do NEXT?
- A. Verify all third-party applications are disabled
- B. Determine if the device has adequate storage available.
- C. Confirm a strong internet connection is available using Wi-Fi or cellular data
- D. Check if the battery is sufficiently charged
Answer: D
Explanation:
Explanation
Since there are no error messages on the device, the technician should check if the battery is sufficiently charged1 If the battery is low, the device may not have enough power to complete the update2 In this scenario, the technician has already determined that there are no error messages on the device. The next best step would be to check if the battery is sufficiently charged. If the battery is low, it could be preventing the device from completing the update process.
Verifying that third-party applications are disabled, determining if the device has adequate storage available, and confirming a strong internet connection are all important steps in troubleshooting issues with mobile devices. However, since the problem in this scenario is related to a failed OS update, it is important to first check the battery level before proceeding with further troubleshooting steps.

NEW QUESTION # 192
A user is unable to access a web-based application. A technician verifies the computer cannot access any web pages at all. The computer obtains an IP address from the DHCP server. Then, the technician verifies the user can ping localhost. the gateway, and known IP addresses on the interne! and receive a response. Which of the following Is the MOST likely reason tor the Issue?
- A. A firewall is blocking the application.
- B. The browser cache needs to be cleared
- C. The incorrect DNS address was assigned.
- D. The wrong VLAN was assigned.
Answer: C
Explanation:
Explanation
DNS (domain name system) is a protocol that translates domain names to IP addresses. If the computer has an incorrect DNS address assigned, it will not be able to resolve the domain names of web-based applications and access them. A firewall, a VLAN (virtual local area network) and a browser cache are not the most likely reasons for the issue, since the computer can ping known IP addresses on the internet and receive a response.

NEW QUESTION # 195
A company recently experienced a security incident in which a USB drive containing malicious software was able to covertly install malware on a workstation. Which of the following actions should be taken to prevent this incident from happening again? (Select two).
- A. Enable a BIOS password.
- B. Update the antivirus definitions.
- C. Install a host-based IDS.
- D. Restrict user permissions.
- E. Disable AutoRun.
- F. Update the password complexity.
- G. Restrict log-in times.
Answer: D,E
Explanation:
AutoRun is a feature of Windows that automatically executes a program or file when a removable media such as a USB drive is inserted into the computer. Disabling AutoRun can prevent a USB drive containing malicious software from covertly installing malware on a workstation, as it would require the user to manually open the drive and run the file. Restricting user permissions can also prevent a USB drive containing malicious software from covertly installing malware on a workstation, as it would limit the user's ability to execute or install unauthorized programs or files. Installing a host-based IDS, restricting log-in times, enabling a BIOS password, updating the password complexity, and updating the antivirus definitions are not actions that can directly prevent this incident from happening again.
NEW QUESTION # 196
A technician removed a virus from a user's device. The user returned the device a week later with the same virus on it. Which of the following should the technician do to prevent future infections?
- A. Install the latest OS patches.
- B. Disable System Restore.
- C. Clean the environment reinstallation.
- D. Educate the end user.
Answer: D
Explanation:
Explanation
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.

https://www.makeuseof.com/tag/difference-32-bit-64-bit-windows/
After upgrading from a 32-bit Windows OS to a 64-bit OS, the company will be able to fully take advantage of the RAM of the computer. This is because a 64-bit operating system is able to use larger amounts of RAM compared to a 32-bit operating system, which may benefit the system's overall performance if it has more than
4GB of RAM installed
NEW QUESTION # 201
A user's home system has been infected with malware. A technician has isolated the system from the network and disabled System Restore. Which of the following should the technician do next?
- A. Perform an antivirus scan.
- B. Enable System Restore.
- C. Run Windows updates.
- D. Reimage the system.
Answer: A
Explanation:
When dealing with a malware-infected system, isolating the system from the network and disabling System Restore are critical initial steps. The next step in the malware removal process should be:
* Perform an antivirus scan:This helps to identify and remove the malware from the system. Running a thorough scan using updated antivirus software is essential to detect and clean any malicious files.
* Run Windows updates:This is important for system security but should be done after the malware is removed to avoid further issues.
* Reimage the system:This is a more drastic measure and should be considered if the antivirus scan cannot fully clean the system.
* Enable System Restore:This should only be done after the system is confirmed to be clean.

NEW QUESTION # 202
A company installed WAPs and deployed new laptops and docking stations to all employees. The docking stations are connected via LAN cables. Users are now reporting degraded network service. The IT department has determined that the WAP mesh network is experiencing a higher than anticipated amount of traffic. Which of the following would be the most efficient way to ensure the wireless network can support the expected number of wireless users?
- A. Adding wireless repeaters throughout the building
- B. Increasing the wireless network adapter metric
- C. Upgrading the current mesh network to support the 802.11 n specification
- D. Replacing non-mobile users' laptops with wired desktop systems
Answer: C
Explanation:
When a WAP (Wireless Access Point) mesh network is experiencing a higher than anticipated amount of traffic, leading to degraded network service, upgrading the network to a more advanced wireless standard can help alleviate the problem. The 802.11n specification, also known as Wireless-N, offers significant improvements over earlier standards like 802.11b/g in terms of speed, range, and reliability. It allows for increased data throughput and better coverage, which can support a higher number of wireless users effectively.
Upgrading to 802.11n:This involves replacing existing WAPs with those that support the 802.11n standard or higher. The upgrade can result in improved network performance by accommodating more wireless connections with higher data rates, reducing congestion and improving overall network efficiency.
Replacing non-mobile users' laptops with wired desktop systems (A) could reduce wireless traffic but may not be feasible or desirable for all users. Increasing the wireless network adapter metric (B) would affect route priority but not overall network capacity. Adding wireless repeaters (C) can extend the range but might also introduce additional latency and does not necessarily increase the network's capacity to handle more users efficiently.
NEW QUESTION # 203

- A. DNS
- B. SSH
- C. IPS
- D. VPN
Answer: D
Explanation:
A VPN (virtual private network) is a protocol that creates a secure tunnel between two devices over the internet, hiding their IP addresses and encrypting their traffic. DNS (domain name system) is a protocol that translates domain names to IP addresses. IPS (intrusion prevention system) is a device that monitors and blocks malicious network traffic. SSH (secure shell) is a protocol that allows remote access and command execution on another device. Verified References: https://www.comptia.org/blog/what-is-a-vpn https://www.

NEW QUESTION # 204
Antivirus software indicates that a workstation is infected with ransomware that cannot be quarantined. Which of the following should be performed first to prevent further damage to the host and other systems?
- A. Remove the LAN card.
- B. Turn off the machine.
- C. Run a full antivirus scan.
- D. Install a different endpoint solution.
Answer: B
Explanation:
Turning off the machine is the first and most urgent step to prevent further damage to the host and other systems. Ransomware can encrypt files, steal data, and spread to other devices on the network if the infected machine remains online. Turning off the machine will stop the ransomware process and isolate the machine from the network12. The other options are either ineffective or risky. Running a full antivirus scan may not detect or remove the ransomware, especially if it is a new or unknown variant. Removing the LAN card may disconnect the machine from the network, but it will not stop the ransomware from encrypting or deleting files on the local drive. Installing a different endpoint solution may not be possible or helpful if the ransomware has already compromised the system or blocked the installation.

Which of the following should be included to approve this change?
- A. Standard maintenance window
- B. Rollback plan
- C. Cost analysis
- D. End-user acceptance
Answer: B
Explanation:
A rollback plan is essential for a change to be approved by a change management review board. It outlines the steps to reverse a change in case something goes wrong, minimizing downtime and mitigating risk. Other items like end-user acceptance and cost analysis are important but not typically the deciding factor for approval.
