• Question 511:

  Which of the following items require special e-waste recycling? (Select two).

  A. Solid-state drive

  B. A/C adapter

  C. Surge protector

  D. Laptop battery

  E. CRT monitor

  F. Power supply

  Correct Answer: DE

  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 .

  Which of the following would typically require the most computing resources from the host computer?

  A. Chrome OS

  B. Windows

  C. Android

  D. macOS

  E. Linux

  Correct Answer: B

  Windows is the operating system that typically requires the most computing resources from the host computer, compared to the other options. Computing resources include hardware components such as CPU, RAM, disk space, graphics card, and network adapter. The minimum system requirements for an operating system indicate the minimum amount of computing resources needed to install and run the operating system on a computer. The higher the minimum system requirements, the more computing resources the operating system consumes. According to the web search results, the minimum system requirements for Windows 10 and Windows 11 are as follows12: CPU: 1 GHz or faster with two or more cores (Windows 10); 1 GHz or faster with two or more cores on a compatible 64-bit processor (Windows 11) RAM: 1 GB for 32-bit or 2 GB for 64-bit (Windows 10); 4 GB (Windows 11) Disk space: 16 GB for 32-bit or 32 GB for 64-bit (Windows 10); 64 GB (Windows 11) Graphics card: DirectX 9 or later with WDDM 1.0 driver (Windows 10); DirectX 12 compatible with WDDM 2.0 driver (Windows 11) Network adapter: Ethernet or Wi-Fi (Windows 10); Ethernet or Wi-Fi that supports 5 GHz (Windows 11) The minimum system requirements for macOS Ventura are as follows: CPU: Intel Core i3 or higher, or Apple M1 chip RAM: 4 GB Disk space: 35.5 GB Graphics card: Metal-capable Network adapter: Ethernet or Wi-Fi The minimum system requirements for Chrome OS are as follows: CPU: Intel Celeron or higher RAM: 2 GB Disk space: 16 GB Graphics card: Integrated Network adapter: Ethernet or Wi-Fi The minimum system requirements for Android are as follows: CPU: 1 GHz or higher RAM: 512 MB Disk space: 8 GB Graphics card: OpenGL ES 2.0 Network adapter: Ethernet or Wi-Fi The minimum system requirements for Linux vary depending on the distribution, but a common example is Ubuntu, which has the following minimum system requirements: CPU: 2 GHz dual core processor or better RAM: 4 GB Disk space: 25 GB Graphics card: 1024 x 768 screen resolution Network adapter: Ethernet or Wi-Fi Based on the comparison of the minimum system requirements, Windows has the highest requirements for CPU, RAM, disk space, and graphics card, while Chrome OS and Android have the lowest requirements. macOS and Linux have moderate requirements, depending on the hardware and software configuration.

References: CompTIA A+ Certification ore 2 Objectives, page 9, section 1.7; CompTIA A+ Core 2 (220- 1102) Certification Study Guide, page 140, section 1.7.

• Question 514:

  A management team at a small office wants to block access to inappropriate websites and create a log of these access attempts. Which of the following is a way to meet these requirements?

  A. Content filter

  B. Screened subnet

  C. Port forwarding

  D. Access control list

  Correct Answer: A

  A content filter is a device or software that blocks or allows access to web pages based on predefined criteria, such as keywords, categories, or ratings. A content filter can also create a log of the blocked or allowed web requests, which can help the management team monitor and audit the web usage of their employees. A content filter is different from the other options because: A screened subnet is a network segment that is protected by two firewalls, one facing the internet and one facing the internal network. A screened subnet can isolate servers or hosts that need to be accessed from both sides, such as a web server or a bastion host. A screened subnet does not filter web content based on predefined criteria, but rather on network addresses, ports, and protocols. Port forwarding is a technique that allows a router to forward packets from one port to another port, usually on a different device. Port forwarding can enable remote access to services or applications that are hosted on a private network, such as a web server or a game server. Port forwarding does not filter web content based on predefined criteria, but rather on destination ports and addresses. An access control list (ACL) is a set of rules that defines which packets are allowed or denied on a network device, such as a router or a firewall. An ACL can filter packets based on source and destination addresses, ports, protocols, and other criteria. An ACL can also create a log of the matched or unmatched packets, which can help the management team troubleshoot and secure their network. An ACL does not filter web content based on predefined criteria, but rather on packet headers and fields.

• Question 515:

  Which of the following is the best reason for sandbox testing in change management?

  A. To evaluate the change before deployment

  B. To obtain end-user acceptance

  C. To determine the affected systems

  D. To select a change owner

  Correct Answer: A

  Sandbox testing is a method of testing changes in a simulated environment that mimics the real one, without affecting the actual production system. Sandbox testing is useful for change management because it allows the testers to evaluate the change before deployment, and ensure that it works as intended, does not cause any errors or conflicts, and meets the requirements and expectations of the stakeholders. Sandbox testing also helps to protect the investment in the existing system, as it reduces the risk of introducing bugs or breaking functionality that could harm the customer experience or the business operations. Sandbox testing also gives the testers more control over the customer experience, as they can experiment with different scenarios and configurations, and optimize the change for the best possible outcome.

• Question 516:

  A user is unable to access a remote server from a corporate desktop computer using the appropriate terminal emulation program. The user contacts the help desk to report the issue. Which of the following clarifying questions would be most effective for the help desk technician to ask the user in order to understand the issue?

  A. What is the error message?

  B. Does the program work on another computer?

  C. Did the program ever work?

  D. Is anyone else having this issue?

  Correct Answer: A

  The most effective clarifying question for the help desk technician to ask the user in order to understand the issue is A. What is the error message? This question will help the technician to identify the possible cause and solution of the problem, as the error message will provide specific information about the nature and location of the error, such as the server name, the port number, the protocol, the authentication method, or the network status. The error message will also help the technician to troubleshoot the issue by following the suggested steps or searching for the error code online. This question is more effective than the other choices because:

  B. Does the program work on another computer? is not a very helpful question, as it will not reveal the source of the error or how to fix it. The program may work on another computer for various reasons, such as different network settings, firewall rules, permissions, or software versions. However, this question will not tell the technician what is wrong with the user's computer or the remote server, or what needs to be changed or updated to make the program work. C. Did the program ever work? is not a very relevant question, as it will not address the current issue or how to resolve it. The program may have worked in the past, but it may have stopped working due to changes in the network configuration, the server status, the software updates, or the user credentials. However, this question will not tell the technician what has changed or how to restore the program functionality. D. Is anyone else having this issue? is not a very useful question, as it will not explain the reason or the solution for the error. The issue may affect only the user, or multiple users, depending on the scope and the impact of the error. However, this question will not tell the technician what is causing the error or how to fix it for the user or the others.

• Question 517:

  Which of the following environments allows for the testing of critical systems without the risk of them being negatively impacted by changes?

  A. Regression

  B. Cloud

  C. Production

  D. Sandbox

  Correct Answer: D

  A sandbox is an isolated environment that allows for the testing of critical systems without the risk of them being negatively impacted by changes. A sandbox can be used to simulate real-world scenarios, experiment with new features, debug errors, or evaluate the performance and security of a system. A sandbox can be created using virtualization, emulation, or containerization technologies. A sandbox prevents any changes made in the testing environment from affecting the production environment, which is the actual system that is used by the end users. https://www.comptia.org/training/books/a-core-2-220-1102-study-guide

• Question 518:

  Remote employees need access to information that is hosted on local servers at the company. The IT department needs to find a solution that gives employees secure access to the company's resources as if the employees were on premises. Which of the following remote connection services should the IT team implement?

  A. SSH

  B. VNC

  C. VPN

  D. RDP

  Correct Answer: C

  A VPN (Virtual Private Network) is a service that allows remote employees to access the company's network resources securely over the internet as if they were on premises. A VPN encrypts the data traffic between the employee's device and the VPN server, and assigns the employee a virtual IP address that belongs to the company's network. This way, the employee can access the local servers, files, printers, and other resources without exposing them to the public internet. A VPN also protects the employee's privacy and identity by masking their real IP address and location.

  A. Perform a low-level format.

  B. Remotely wipe the device.

  C. Degauss the device.

  D. Provide the GPS location of the device.

  Correct Answer: B

  Remotely wiping the device is the best option to prevent unauthorized access to the company data stored on the phone. A low-level format, degaussing, or providing the GPS location of the device are not feasible or effective actions to take in this scenario.

• Question 520:

  When a user is in the office, the user's mobile phone loads applications and web browses very slowly on a cellular connection. Which of the following is the best way to fix this issue?

  A. Connect to the company's Wi-Fi network.

  B. Change the settings on the phone to connect to a different cellular tower.

  C. Install a cellular repeater at the office for this user.

  D. Update all applications on the phone.

  Correct Answer: A

  The best way to fix the issue of slow cellular connection in the office is to connect to the company's Wi-Fi network. This will allow the user's mobile phone to access the internet through a faster and more reliable wireless network, instead of relying on the cellular network. Connecting to the Wi-Fi network will also save the user's data usage and battery life. Some of the factors that can affect the cellular connection speed are the distance from the cell tower, the obstructions between the phone and the tower, the network congestion, the network technology, and the features of the phone12. In the office, the user may experience a weak or unstable cellular signal due to the building structure, the location, or the interference from other devices. Therefore, switching to the Wi-Fi network can improve the performance of the phone's applications and web browsing.
