NEW QUESTION # 48
A user's Windows computer seems to work well at the beginning of the day. However, its performance degrades throughout the day, and the system freezes when several applications are open. Which of the following should a technician do to resolve the issue? (Select two).
- A. Reinstall the OS.
- B. Uninstall unnecessary software.
- C. Increase the hard drive space.
- D. Install the latest GPU drivers.
- E. Increase the RAM.
- F. Disable scheduled tasks.
Answer: B,E
Explanation:
Explanation
The most likely causes of the user's Windows computer performance degradation and freezing are insufficient RAM and excessive software running in the background. Therefore, the technician should do the following to resolve the issue:
Increase the RAM. RAM is the memory that the computer uses to store and run applications and processes. If the RAM is not enough to handle the workload, the computer will use the hard drive as a virtual memory, which is much slower and can cause performance issues. Increasing the RAM will allow the computer to run more applications and processes smoothly and avoid freezing. The technician should check the system requirements of the applications that the user needs to run, and install additional RAM modules that are compatible with the motherboard and the existing RAM. The technician should also make sure that the system is managing the page file size automatically, or adjust it manually to optimize the virtual memory usage12.
Uninstall unnecessary software. Software that the user does not need or use can take up valuable disk space and system resources, and can interfere with the performance of other applications. Some software may also run in the background or start automatically when the computer boots up, which can slow down the system and cause freezing. The technician should help the user to identify and uninstall unnecessary software from the control panel or the settings app, and disable unnecessary startup programs from the task manager or the system configuration tool. The technician should also check for and remove viruses and malware that may affect the system performance134.

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 # 50
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. Install a different endpoint solution.
- C. Run a full antivirus scan.
- D. Turn off the machine.
Answer: D
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.

A badge reader can help prevent unauthorized entry or intrusion into a building or a restricted area. A motion sensor is a device that detects movement and triggers an alarm or an action when motion is detected. A motion sensor can help deter or alert potential intruders or trespassers in a building or an area.
Multifactor authentication is a method of verifying identity using two or more factors, such as something you know, something you have or something you are. Multifactor authentication is not a device that can be deployed to enhance physical security for a building but a technique that can be used to enhance logical security for systems or services. Personal identification number is a numeric code that can be used as part of authentication or access control. Personal identification number is not a device that can be deployed to enhance physical security for a building but an example of something you know factor in multifactor authentication. Firewall is a device or software that filters network traffic based on rules and policies. Firewall is not a device that can be deployed to enhance physical security for a building but a device that can be used to enhance network security for systems or services. Soft token is an application or software that generates one-time passwords or codes for authentication purposes.

A technician is investigating options to secure a small office's wireless network. One requirement is to allow automatic log-ins to the network using certificates instead of passwords. Which of the following should the wireless solution have in order to support this feature?
- A. MFA
- B. EAP-EKE
- C. AES
- D. RADIUS
Answer: D
Explanation:
RADIUS is the correct answer for this question. RADIUS stands for Remote Authentication Dial-In User Service, and it is a protocol that provides centralized authentication, authorization, and accounting for wireless networks. RADIUS can support certificate-based authentication, which allows users to log in to the network automatically without entering passwords. RADIUS also provides other benefits, such as enforcing security policies, logging user activities, and managing network access. AES, EAP-EKE, and MFA are not wireless solutions, but rather encryption algorithms, authentication methods, and security factors, respectively. Reference:

A user receives an error message from an online banking site that states the following:
Your connection is not private. Authority invalid.
Which of the following actions should the user take NEXT?
- A. Reinstall the browser.
- B. Report the error to the bank.
- C. Proceed to the site.
- D. Use a different browser.
Answer: B

NEW QUESTION # 65
An implementation specialist is replacing a legacy system at a vendor site that has only one wireless network available. When the specialist connects to Wi-Fi. the specialist realizes the insecure network has open authentication. The technician needs to secure the vendor's sensitive data. Which of the following should the specialist do FIRST to protect the company's data?
- A. Configure MFA on the network.
- B. Manually configure an IP address, a subnet mask, and a default gateway.
- C. Connect to the vendor's network using a VPN.
- D. Change the network location to private.
Answer: C
Explanation:
Explanation
The first thing that the specialist should do to protect the company's data on an insecure network with open authentication is to connect to the vendor's network using a VPN. A VPN stands for Virtual Private Network and is a technology that creates a secure and encrypted connection over a public or untrusted network. A VPN can protect the company's data by preventing eavesdropping, interception or modification of the network traffic by unauthorized parties. A VPN can also provide access to the company's internal network and resources remotely. Manually configuring an IP address, a subnet mask and a default gateway may not be necessary or possible if the vendor's network uses DHCP to assign network configuration parameters automatically. Manually configuring an IP address, a subnet mask and a default gateway does not protect the company's data from network attacks or threats. Changing the network location to private may not be advisable or effective if the vendor's network is a public or untrusted network. Changing the network location to private does not protect the company's data from network attacks or threats. Configuring MFA on the network may not be feasible or sufficient if the vendor's network has open authentication and does not support or require MFA. Configuring MFA on the network does not protect the company's data from network attacks or threats. References: CompTIA A+ Core 2 (220-1002) Certification Exam Objectives Version 4.0, Domain

NEW QUESTION # 67
Which of the following could be used to implement secure physical access to a data center?
- A. Alarm system
- B. Geofence
- C. Motion sensor
- D. Badge reader
Answer: D
Explanation:
Badge readers are used to implement secure physical access to a data center. They are used to read the identification information on an employee's badge and grant access to the data center if the employee is authorized2.
This system requires individuals to have an access badge that contains their identification information or a unique code that can be scanned by a reader. After the badge is scanned, the system compares the information on the badge with the authorized personnel database to authenticate if the individual has the required clearance to enter that area. The other options listed, such as a geofence, alarm system, or motion sensor are security measures that may be used in conjunction with badge readers, but do not provide identification and authentication features.
NEW QUESTION # 68
An employee has repeatedly contacted a technician about malware infecting a work computer. The technician has removed the malware several times, but the user's PC keeps getting infected. Which of the following should the technician do to reduce the risk of future infections?
- A. Educate the end user
- B. Restore the system from backups.
- C. Configure the firewall.
- D. Update the antivirus program.
Answer: A
Explanation:
Malware is software that infects computer systems to damage, disable or exploit the computer or network for various malicious purposes5. Malware is typically distributed via email attachments, fake internet ads, infected applications or websites, and often relies on user interaction to execute6. Therefore, one of the most effective ways to prevent malware infections is to educate the end user about the common signs and sources of malware, and how to avoid them7. Configuring the firewall, restoring the system from backups, and updating the antivirus program are also important security measures, but they do not address the root cause of the user's repeated infections, which is likely due to a lack of awareness or caution.
