• Question 681:

  A user reports that a laptop correctly connects to the internet when docked at the office but is unable to access the internet when at home. Which of the following should the technician do first?

  A. Contact the user's home ISP

  B. Give the user a dock to use at home.

  C. Disable network security settings.

  D. Enable the wireless adapter.

  Correct Answer: D

  Explanation: A wireless adapter is a device that allows a laptop to connect to a wireless network, such as a home Wi-Fi router. A wireless adapter can be either internal or external, and it can be enabled or disabled by the user or the operating

  system. If the wireless adapter is disabled, the laptop will not be able to access the internet when it is not connected to a wired network, such as the office dock. The technician should do the following steps to enable the wireless adapter:

  Check the physical switch or button on the laptop that controls the wireless adapter. Some laptops have a switch or button on the side, front, or keyboard that can turn on or off the wireless adapter. Make sure the switch or button is in the on

  position.

  Check the software settings for the wireless adapter. In Windows 10, you can do this by clicking on the network icon in the system tray, and then clicking on the Wi- Fi icon. Make sure the Wi-Fi is turned on. You can also go to Settings >

  Network and Internet > Wi-Fi and make sure the Wi-Fi is turned on. Check the device manager for the wireless adapter. In Windows 10, you can do this by right-clicking on the Start menu and selecting Device Manager. Expand the Network

  adapters category and look for your wireless adapter. Make sure it is enabled and has no errors. You can right-click on it and select Enable device or Update driver if needed. If none of these steps work, there may be a hardware or software

  problem with the wireless adapter that requires further troubleshooting or replacement.

• Question 683:

  Which of the following is considered a connectionless protocol?

  A. SSH

  B. TCP

  C. HTTPS

  D. UDP

  Correct Answer: D

  Explanation: The correct answer is D. UDP. UDP (User Datagram Protocol) is a connectionless protocol that does not establish a connection before sending or receiving data. UDP simply sends datagrams to the destination without checking if the receiver is ready or not. UDP does not guarantee reliable delivery, error correction, or in-order arrival of the data. UDP is faster and more efficient than connection-oriented protocols for applications that do not require reliability, such as streaming audio or video1 A. SSH (Secure Shell) is not a correct answer. SSH is a connection-oriented protocol that uses TCP (Transmission Control Protocol) as its transport layer. SSH establishes a secure and encrypted connection between two network endpoints before exchanging data. SSH provides authentication, confidentiality, and integrity for remote login and command execution2

  B. TCP (Transmission Control Protocol) is not a correct answer. TCP is a connection- oriented protocol that establishes a connection before sending or receiving data. TCP ensures reliable delivery, error correction, and in-order arrival of the data. TCP is slower and more complex than connectionless protocols, but it provides more reliability and quality of service for applications that require it, such as web browsing or email1 C. HTTPS (Hypertext Transfer Protocol Secure) is not a correct answer. HTTPS is a connection-oriented protocol that uses TCP as its transport layer and SSL/TLS as its security layer. HTTPS establishes a secure and encrypted connection between a web browser and a web server before exchanging data. HTTPS provides authentication, confidentiality, and integrity for web transactions, such as online banking or shopping1

• Question 684:

  A. DDR5

  B. ECC

  C. DDR4

  D. Dual-channel

  Correct Answer: B

  Explanation: ECC (Error Correcting Code) memory is a type of memory that can detect and correct errors that may occur during data transmission or storage. ECC memory is essential for high-availability computing, as it prevents data corruption and system crashes2. References: ECC Memory

• Question 685:

  A user reports that a printer pulls multiple sheets of paper from the paper tray instead of a single sheet. Which of the following should a technician investigate to resolve this issue? (Select two).

  A. Toner cartridge

  B. Tractor feed

  C. Pickup roller

  D. Separation pad

  E. Duplexer

  F. Fuser

  Correct Answer: CD

  Explanation: The correct answers are C. Pickup roller and D. Separation pad. A pickup roller is a rubber wheel that grabs the paper from the paper tray and feeds it into the printer. A separation pad is a small piece of cork or rubber that prevents more than one sheet of paper from being fed at a time. If the pickup roller or the separation pad is worn out, dirty, or damaged, it can cause the printer to pull multiple sheets of paper instead of a single sheet. This can lead to paper jams, misprints, or wasted paper. To resolve this issue, a technician should investigate the condition of the pickup roller and the separation pad and replace them if necessary. The technician should also clean the paper tray and make sure the paper is loaded correctly and not stuck together. A toner cartridge is a component that contains the toner powder used to create the printout on a laser printer. A tractor feed is a mechanism that uses sprockets to move continuous paper through a dot matrix printer. A duplexer is a device that allows a printer to print on both sides of the paper automatically. A fuser is a part of a laser printer that melts the toner onto the paper using heat and pressure. None of these components are related to the issue of pulling multiple sheets of paper from the paper tray. Reference: Types of Printers--What You Need to Know for the CompTIA A+ Exams

• Question 687:

  After moving a user's legacy workstation into a new private office that does not have a LAN connection, the technician is unable to connect to a wireless network. Which of the following is the most likely reason?

  A. Missing Wi-Fi adapter

  B. Wi-Fi AP replacement

  C. Hidden Wi-Fi SSID

  D. Incorrect Wi-Fi channel

  Correct Answer: A

  Explanation: The most likely reason is A. Missing Wi-Fi adapter. A Wi-Fi adapter is a device that allows a computer to connect to a wireless network. A legacy workstation may not have a built-in Wi-Fi adapter, or it may have an outdated or incompatible one. If the workstation does not have a Wi-Fi adapter, it will not be able to detect or access any wireless networks, regardless of the location, signal strength, or configuration of the network. To fix this issue, the technician can install a Wi-Fi adapter on the workstation, either internally or externally. An internal Wi-Fi adapter is a card that fits into a slot on the motherboard, while an external Wi-Fi adapter is a device that plugs into a USB port. The technician should choose a Wi-Fi adapter that is compatible with the workstation's operating system, hardware, and wireless standards . The other options are less likely to be the reason for the issue. A Wi-Fi AP replacement means changing the wireless access point that provides the network connection. This may affect the network name, password, or settings, but it should not prevent the workstation from detecting any wireless networks. A hidden Wi-Fi SSID means that the network name is not broadcasted publicly, but it can still be accessed by entering the name manually. A hidden Wi-Fi SSID may make it harder to find the network, but it should not prevent the workstation from detecting other wireless networks. An incorrect Wi-Fi channel means that the network is using a frequency band that is crowded or interfered by other devices. This may affect the network performance or stability, but it should not prevent the workstation from detecting any wireless networks.

• Question 688:

  A technician is designing a new laptop for a local construction company. Company employees will move the laptop around frequently and are likely to drop the laptop while working. Which of the following drives should the technician install to mitigate for potential damage?

  A. S.M.A.R.T

  B. SCSI

  C. RAID

  D. Solid-state

  Correct Answer: D

  Solid-state drives (SSDs) are the best choice for laptops that are likely to drop while working, as they have no moving parts and are more resistant to shock and vibration than hard-disk drives (HDDs). SSDs also offer faster performance, lower power consumption, and less noise and heat than HDDs. SSDs use flash memory chips to store data, unlike HDDs that use spinning platters and read/write heads. SSDs can be connected to laptops using various interfaces, such as SATA, PCIe, or NVMe. The other options are not suitable for this scenario. S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) is a feature that monitors the health and performance of HDDs and SSDs, but it does not prevent damage from dropping. SCSI (Small Computer System Interface) is an interface that connects various devices, such as HDDs, SSDs, scanners, and printers, to a computer, but it is not commonly used in laptops. RAID (Redundant Array of Independent Disks) is a system that combines multiple HDDs or SSDs into a single logical unit, providing redundancy, performance, or both, but it is not feasible or practical to implement RAID in a laptop.

• Question 689:

  During an OS migration, a technician is unable to find compatible current software for a specialized hardware device. Which of the following actions should the technician take to complete the migration?

  A. Restrict user access.

  B. Virtualize the application.

  C. Replace the PC.

  D. Upgrade the BIOS to UEFI.

  Correct Answer: B

  Virtualizing the application is the best action that a technician can take to complete the OS migration when there is no compatible current software for a specialized hardware device. Virtualizing the application means running the application in a virtual machine (VM) that emulates the previous OS environment that supports the application and the hardware device. This way, the technician can avoid the need to replace the PC or the hardware device, or to restrict user access to the application. Virtualizing the application also allows the technician to benefit from the new OS features and security updates, while maintaining the functionality and compatibility of the application and the hardware device. The other options are not as effective or feasible for this scenario. Restricting user access may prevent unauthorized or accidental changes to the application or the hardware device, but it does not solve the compatibility issue or allow the OS migration to proceed. Replacing the PC or the hardware device may be costly, time-consuming, or impractical, especially if the hardware device is rare, expensive, or customized. Upgrading the BIOS to UEFI may improve the boot speed, security, and compatibility of the PC, but it does not guarantee that the application or the hardware device will work with the new OS.

• Question 690:

  Which of the following translates a hostname to IP addresses?

  A. AAA

  B. DHCP

  C. DNS

  D. UTM

  Correct Answer: C

  Explanation: DNS stands for Domain Name System, which is a network service that translates hostnames to IP addresses. Hostnames are human-readable names that identify devices or services on the Internet, such as www.google.com or mail.yahoo.com. IP addresses are numerical identifiers that specify the location of devices or services on the Internet, such as 172.217.14.206 or 98.137.11.163. DNS allows users to access websites or services by using hostnames instead of IP addresses, which are easier to remember and type. DNS also allows hostnames to change their IP addresses without affecting the users, which can improve performance and security.
