• Question 602:

  A technician receives a phone call from a traveling sales representative indicating that the maps application on a phone is not working. The representative runs a speed test on the phone and gets ~10Mbps in both directions. Which of the following settings should the technician check first to troubleshoot the issue?

  A. Airplane mode

  B. PRL

  C. GPS

  D. LTE

  Correct Answer: C

  GPS (Global Positioning System) is a feature that allows a phone to determine its location by receiving signals from satellites. A maps application relies on GPS to provide accurate directions and navigation. If GPS is turned off or not working properly, the maps application may not function as expected. The other options are not relevant to the issue. Airplane mode is a setting that disables all wireless communication on a phone, including cellular, Wi-Fi, Bluetooth, and GPS. However, since the representative runs a speed test and gets ~10Mbps in both directions, it means that airplane mode is not enabled. PRL (Preferred Roaming List) is a database that contains information about the cellular towers and networks that a phone can connect to. Updating the PRL can improve the phone's signal strength and coverage, but it does not affect the maps application. LTE (Long Term Evolution) is a standard for high-speed wireless communication on mobile devices. It is related to the cellular data speed and quality, but not to the maps application. To troubleshoot the issue, the technician should check the GPS settings on the phone and make sure that it is turned on and has a clear view of the sky. The technician should also verify that the maps application has permission to access the GPS location. If the problem persists, the technician may suggest resetting the network settings, updating the phone's software, or contacting the maps application's support team.

• Question 603:

  Which of the following devices is capable of dynamically distributing an IP address?

  A. Hub

  B. Switch

  C. Injector

  D. Router

  Correct Answer: D

  Explanation: A router is a device that can dynamically distribute an IP address to the devices connected to its network using a protocol called DHCP (Dynamic Host Configuration Protocol). DHCP allows a router to automatically assign an IP address and other network configuration information to a device when it joins the network, without requiring manual intervention from the administrator. A router can also act as a gateway between different networks, such as a local area network (LAN) and the internet1. A hub is a device that connects multiple devices on a network and forwards data packets between them. However, a hub does not assign IP addresses or perform any routing functions. A hub operates at the physical layer of the OSI model and does not understand IP addresses or other network protocols. A switch is a device that connects multiple devices on a network and forwards data packets between them based on their MAC addresses. A switch can improve the performance and security of a network by reducing collisions and isolating traffic. However, a switch does not assign IP addresses or perform any routing functions. A switch operates at the data link layer of the OSI model and does not understand IP addresses or other network protocols. An injector is a device that provides power to another device over an Ethernet cable, such as a wireless access point or a security camera. This is also known as Power over Ethernet (PoE). An injector does not assign IP addresses or perform any routing functions. An injector operates at the physical layer of the OSI model and does not understand IP addresses or other network protocols.

• Question 604:

  A technician is creating a consecutive range of IP addresses that a server can select from to fulfill requests from network clients. Which of the following is the technician creating?

  A. DHCP scope

  B. Static IP list

  C. DNS A records

  D. Automatic private IP addressing

  Correct Answer: A

  Explanation: The correct answer is A. DHCP scope. A DHCP scope is a consecutive range of IP addresses that a DHCP server can select from to fulfill requests from network clients. A DHCP server is a device that automatically assigns IP addresses and other network configuration parameters to devices that request them. A DHCP scope defines the pool of available IP addresses, as well as the subnet mask, default gateway, DNS servers, and lease duration for each IP address. A DHCP scope can also include exclusions, reservations, and policies to customize the IP address allocation process12. A static IP list is a list of IP addresses that are manually assigned to devices and do not change over time. A static IP list does not require a DHCP server, but it requires more administrative effort and coordination to avoid conflicts or errors. A static IP list is not a consecutive range of IP addresses that a server can select from3. DNS A records are DNS records that map a domain name to an IPv4 address. DNS is a system that translates human-readable domain names into machine-readable IP addresses. DNS A records are not a range of IP addresses that a server can select from, but a way of resolving domain names to IP addresses. Automatic private IP addressing (APIPA) is a feature of Windows that allows devices to self-assign an IP address in the absence of a DHCP server or a static IP configuration. APIPA uses the 169.254.0.0/16 address range, which is reserved for link-local communication. APIPA does not create a range of IP addresses that a server can select from, but a fallback mechanism for devices that cannot obtain an IP address from another source.

• Question 605:

  A user needs to transfer files from an Apple phone to a workstation. Which of the following connection types should the user utilize?

  A. USB-C

  B. Serial

  C. Lightning

  D. NFC

  Correct Answer: C

  Lightning is a proprietary connection type that is used by Apple devices, such as iPhones, iPads, and iPods, to transfer data, charge, and connect to accessories. Lightning cables have a reversible 8-pin connector that can be plugged into a USB port on a workstation or a power adapter. USB-C, serial, and NFC are not compatible with Apple phones.

• Question 606:

  A company recently enabled two-factor authentication in order to enhance security. Users should be prompted for two-factor authentication when working outside of the office, but are also being prompted when connecting to the office Wi-Fi. Which of the following should the technician do?

  A. Leave the current rules in place and disable Wi-Fi on all devices.

  B. Implement allow listing and add the office IP address as an exception.

  C. Remove two-factor authentication from the users' accounts.

  D. Substitute hard tokens in place of soft tokens.

  Correct Answer: B

  Explanation: Allow listing is a security technique that allows only specific IP addresses or domains to access a network or a service. By adding the office IP address as an exception, the company can prevent two-factor authentication from

  being triggered when users are connected to the office Wi-Fi, since the office network is considered trusted. This way, users will only be prompted for two-factor authentication when working outside of the office, which enhances security.

• Question 607:

  Which of the following display types is available for laptops?

  A. OLED

  B. CRT

  C. DLP

  D. Plasma

  Correct Answer: A

  Explanation: The correct answer is A. OLED. OLED stands for Organic Light-emitting Diode, and it is one of the three display types available for laptops, along with TN (Twisted Nematic) and IPS (In-Plane Switching) panels1. OLED displays use organic compounds that emit light when an electric current is applied, unlike LCD displays that use a backlight to illuminate the pixels. OLED displays have several advantages over LCD displays, such as higher contrast, wider viewing angles, faster response times, and lower power consumption2. However, OLED displays are also more expensive, less common, and more prone to burn-in than LCD displays2. CRT (Cathode Ray Tube), DLP (Digital Light Processing), and Plasma are not display types for laptops. CRT is an old technology that uses a vacuum tube to project an image on a phosphor screen. CRT monitors are bulky, heavy, and consume a lot of power3. DLP is a technology that uses a digital micromirror device and a light source to project an image on a screen or a wall. DLP is mainly used for projectors, not laptops4. Plasma is a technology that uses gas-filled cells that emit light when an electric current is applied. Plasma displays are mainly used for large-screen TVs, not laptops. References:

• Question 608:

  A company laptop uses a docking station with an integrated NIC and is unable to access a wired SOHO network using DHCP. A technician runs ipconfig anddiscovers the laptop has an IPv4 assignment of 169.254.0.9. The NIC does not have any link or activity lights on. Which of the following should the technician do next?

  A. Restart the laptop in safe mode.

  B. Reboot the DHCP server.

  C. Reset the network adapter.

  D. Replace the laptop.

  E. Reseat the laptop in the docking station.

  Correct Answer: C

  Given the symptoms described (laptop unable to access the network, IPv4 assignment of 169.254.0.9, no link or activity lights on the NIC), the technician should consider the following steps:

  C. Reset the network adapter.

  Explanation:

  The assignment of an IPv4 address in the 169.254.x.x range typically indicates that the laptop was unable to obtain an IP address from the DHCP server. This range is reserved for Automatic Private IP Addressing (APIPA) when a device cannot obtain a valid IP address.

  The absence of link or activity lights on the NIC suggests a potential hardware or connection issue.

• Question 609:

  A technician replaces a laptop hard drive with an M.2 SSD. When the technician reboots the laptop, the laptop does not detect the SSD. Which of the following should the technician configure for the system?

  A. HSM

  B. Boot options

  C. UEFI settings

  D. TPM

  Correct Answer: C

  Explanation: UEFI stands for Unified Extensible Firmware Interface, and it is a type of firmware that controls the boot process of a computer. UEFI settings allow the technician to configure various aspects of the boot process, such as the boot order, the boot mode, and the security options. If the technician replaces a laptop hard drive with an M.2 SSD, they may need to adjust the UEFI settings to enable the system to detect and boot from the new drive.

• Question 610:

  A restaurant calls the support line about its 3in (2.5cm) point-of-sale printer that is only printing fully black receipts. Which of the following should the technician check in order to resolve the issue? (Select two).

  A. Power supply

  B. Humidity

  C. Rollers

  D. Fuser

  E. Heating element

  F. Room temperature

  Correct Answer: CE

  Explanation: The correct answers are C. Rollers and E. Heating element.

  A 3in (2.5cm) point-of-sale printer is a type of thermal printer that uses heat to print receipts on special thermal paper. The printer has a heating element that heats up the paper as it passes through the rollers, creating black marks on the paper where the heat is applied. The heating element and the rollers are two critical components of the thermal printer that can affect the quality of the printout. If the printer is only printing fully black receipts, it means that the heating element is overheating or malfunctioning, causing the entire paper to turn black. The heating element may need to be replaced or repaired by a technician. Alternatively, the rollers may be dirty or damaged, causing the paper to stick to the heating element and get burned. The rollers may need to be cleaned or replaced by a technician. The other options are not likely to cause the printer to print fully black receipts. The power supply may affect the printer's performance, but it would not cause the heating element to overheat or the rollers to malfunction. The humidity and room temperature may affect the quality of the thermal paper, but they would not cause the entire paper to turn black. The fuser is a component of a laser printer, not a thermal printer, and it has no effect on the point-of-sale printer.
