Which of the following is the default gateway?

172.25.1.252

172.25.1.39

172.25.1.4

255.255.255.0

Explanation
The default gateway is the IP address of the router or device that connects a network to another network or the internet. In the output below, the default gateway is 172.25.1.252, as shown in the line “Default Gateway . . . .
. . . . . : 172.25.1.252″. The other IP addresses are not default gateways, but either local IP addresses (172.25.1.39 and 172.25.1.4) or subnet masks (255.255.255.0).

NO.142 Which of the following would be BEST reason to use a virtual machine as a sandbox?

To test new software in a safe environment

To increase the efficient use of computing resources

To run multiple machines on the same hardware

To have dedicated hardware for a single system

The main reason to use a virtual machine as a sandbox is to test new software in a safe environment without risking the integrity of the host operating system.

NO.145 A user takes a tablet to a technician because the cursor on it keeps drifting. The technician notices the screen does not appear to be damaged. Which of the following is the most likely cause of the cursor issue?

The screen is physically damaged.

The screen rotation is incorrect.

The touch-pen battery is depleted.

The screen needs to be recalibrated.

The screen needs to be recalibrated. The cursor drift is a common symptom of a misaligned touch screen, which can be caused by physical shocks, temperature changes, or software updates. The screen can be recalibrated using the tablet’s settings or a utility program. The screen is not physically damaged, as there is no visible crack or break. The screen rotation is not related to the cursor drift, as it only affects the orientation of the display. The touch-pen battery is not relevant, as the cursor drift occurs even without using the pen.

NO.146 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?

Restart the laptop in safe mode.

Replace the laptop.

Reboot the DHCP server.

Reset the network adapter.

Reseat the laptop in the docking station.

Explanation
The most likely answer is E. Reseat the laptop in the docking station.
The IPv4 address of 169.254.0.9 indicates that the laptop is using an Automatic Private IP Address (APIPA), which means that it could not obtain a valid IP address from the DHCP server on the network1. This could be caused by a physical or logical problem with the network adapter, the cable, the docking station, or the network itself2.
One of the possible solutions is to reseat the laptop in the docking station, which means to remove it and insert it again, making sure that it is properly aligned and connected. This can help fix any loose or faulty connections between the laptop and the docking station, and between the docking station and the network cable3. Reseating the laptop can also trigger a new DHCP request and renew the IP address4.
Other possible solutions include resetting the network adapter, replacing the network cable, rebooting the DHCP server, or restarting the laptop in safe mode. However, these are less likely to be effective than reseating the laptop, as they involve more steps and may not address the root cause of the problem234.
Replacing the laptop is an extreme and unnecessary measure, as there is no evidence that the laptop itself is faulty.

NO.147 A technician is receiving reports that the entire office sporadically loses network connectivity throughout the day. The technician determines the root cause to be EMI. Which of the following cable mediums would be the MOST cost effective without sacrificing system performance?

Coaxial

Shielded Cat 6

Plenum Cat 5e

Multimode fiber

In this situation, the MOST cost-effective cable medium that would not sacrifice system performance would be B. Shielded Cat 6. Electromagnetic interference (EMI) can disrupt network connectivity by interfering with the signals transmitted over network cables. Shielded Cat 6 cables are designed to provide protection against EMI by incorporating a layer of shielding material around the cable’s conductors. This shielding helps to prevent EMI from interfering with the signals transmitted over the cable.

NO.148 Which of the following is a valid use for PaaS?

Off-site backups

An application development environment

A virtual server installation and configuration model

A web application for asset management

PaaS (Platform as a Service) is a cloud computing model in which a provider offers a platform that allows developers to create, run, and manage applications without the complexity of building and maintaining the infrastructure. An application development environment is a valid use for PaaS. Reference: CompTIA A+ Certification Exam Objectives 1001, 1.7

NO.149 Which of the following connectors can be plugged into a Thunderbolt 3 port on a laptop?

USB-A

USB-C

miniUSB

microUS3

Thunderbolt 3 is a USB-C port, so any device with a USB-C connector can be plugged into it. MiniUSB, microUSB and USB-A are not compatible with Thunderbolt 3.

NO.150 Which of the following should the label on a network jack faceplate refer to?

MAC address

Patch panel port

Switch port in use

VLAN identification

A network jack faceplate is a device that covers and protects the network jack or outlet on a wall or a floor. A network jack or outlet is a physical interface that allows a network cable, such as an Ethernet cable, to be plugged into a network device, such as a computer or a printer. A network jack faceplate usually has one or more ports that correspond to different types of network cables, such as RJ-45, RJ-11, or coaxial.
A label on a network jack faceplate should refer to the patch panel port that the network jack or outlet is connected to. A patch panel is a device that connects multiple network cables in an organized and convenient way. A patch panel has a number of ports that correspond to different cables, such as Ethernet, coaxial, or fiber-optic cables. A patch panel can help simplify the wiring and management of a network, as well as provide flexibility and scalability for adding or changing network devices.
By labeling the network jack faceplate with the patch panel port, the network technician can easily identify and trace the cable that is connected to the network jack or outlet. This can help to troubleshoot and resolve network issues, such as connectivity, performance, or configuration problems. It can also help to avoid confusion or errors when installing or modifying network cables.

NO.151 A technician is installing a power supply in a workstation that contains a high-end graphics card, a 3GHz processor, and two cooling fans. Which of the following specifications should the technician verify before installing the new power supply?

The wattage

The chassis ventilation

The motherboard’s firmware

The cables’ color coding

The most important specification that the technician should verify before installing the new power supply is A) The wattage.
The wattage of a power supply is the measure of how much power it can deliver to the components of a computer. The wattage of a power supply should match or exceed the total power consumption of the computer, otherwise the computer may not function properly or may experience instability, overheating, or damage12.
To calculate the total power consumption of a computer, the technician can use a tool such as a power supply calculator, which can estimate the required wattage based on the components and features of the computer. For example, using one of the web search results3, I entered the following information:
* CPU: 3 GHz processor
* GPU: High-end graphics card
* RAM: 16 GB DDR4
* SSD: 1 x 500 GB
* HDD: 1 x 1 TB
* Optical Drive: 1 x DVD-RW
* Fans: 2 x 120 mm
* Other Devices: Keyboard, Mouse, Monitor
The tool estimated that the recommended PSU wattage for this computer is 550 W. Therefore, the technician should verify that the new power supply has at least this wattage before installing it.
The chassis ventilation, the motherboard’s firmware, and the cables’ color coding are not as important as the wattage for installing a new power supply. The chassis ventilation is related to the airflow and cooling of the computer, which can affect the performance and lifespan of the components. The motherboard’s firmware is the software that controls the basic functions of the motherboard, such as booting, input/output, and memory management. The cables’ color coding is a standard way of identifying the function and polarity of the wires in a power supply. However, none of these specifications are directly related to the power delivery or compatibility of the new power supply.

NO.152 Which of the following network devices is used to separate broadcast domains?

Switch

Wireless access point

Router

Hub

A router (option C) is a network device that is used to separate broadcast domains. A broadcast domain is a logical division of a computer network in which all nodes can reach each other by broadcast at the data link layer. Routers operate at the network layer of the OSI model and use routing tables to determine the best path for forwarding packets between different networks.
By separating broadcast domains, routers can help to reduce network congestion and improve performance. When a router receives a broadcast packet on one of its interfaces, it does not forward the packet to any other interfaces. This means that only devices within the same broadcast domain as the sender will receive the broadcast packet.

NO.153 A graphic designer wants to purchase a laptop that provides the most accurate color spectrum available when viewed from as many different angles as possible. Which is the following display types would best meet the graphic designer’s requirements?

LCD

lasma

OLED

VGA

Explore
The correct answer is C. OLED.
OLED stands for Organic Light-Emitting Diode, and it is a type of display technology that uses organic compounds to create light and color. Unlike LCD (Liquid Crystal Display) or Plasma displays, OLED does not require a backlight or a filter to produce images. This means that OLED can offer higher contrast, wider color gamut, and better viewing angles than other display types.
LCD displays use liquid crystals that are sandwiched between two polarizing filters and illuminated by a backlight. The liquid crystals can change their orientation and block or allow light to pass through the filters. LCD displays can have different panel types, such as IPS (In-Plane Switching), VA (Vertical Alignment), or TN (Twisted Nematic), which affect the color accuracy, response time, and viewing angles of the display.
Plasma displays use gas-filled cells that are electrically charged to create plasma, which emits ultraviolet light. The ultraviolet light then excites phosphors that emit visible light and color. Plasma displays can produce deep blacks and high contrast, but they are also prone to image retention, screen burn-in, and high power consumption.
VGA stands for Video Graphics Array, and it is not a display type but a video interface standard that was introduced in 1987. VGA can transmit analog signals from a computer to a monitor, but it has low resolution and limited color depth compared to modern digital standards such as HDMI or DisplayPort.
Therefore, OLED is the best display type for graphic designers who want the most accurate color spectrum and the widest viewing angles. OLED displays can also be thinner and lighter than LCD or Plasma displays, which makes them ideal for laptops. However, OLED displays are also more expensive and less durable than other display types, and they may suffer from image retention or burn-in over time.

NO.155 A technician recently installed a new printer that is being shared over the network via a 64-bit Windows Print Server Two users, who have computers with a legacy OS, are unable to print to this new printer. Which of the following should the technician do to resolve this issue?

Enable 32-bit drivers on the Print Server.

Enable Print Spooler and restart the computer.

Run Windows Update on the users’ computers_

Update the computers to a 64-bit driver.

The correct answer is
A) Enable 32-bit drivers on the Print Server.
A print server is a computer or device that manages the printing requests from multiple clients over a network. A print server can share one or more printers with different types of clients, such as Windows, Mac, or Linux. However, to ensure compatibility and functionality, the print server must have the appropriate drivers for each printer and each client1.
A driver is a software component that enables the communication and interaction between a device and an operating system. A driver must match the specifications and features of the device, as well as the architecture and version of the operating system. A driver that is incompatible with either the device or the operating system may cause errors, malfunctions, or performance issues2.
In this scenario, the technician installed a new printer that is being shared over the network via a 64-bit Windows Print Server. This means that the print server has a 64-bit operating system and a 64-bit driver for the printer. However, two users who have computers with a legacy OS (an older or outdated operating system) are unable to print to this new printer. This may be because their computers have a 32-bit operating system and require a 32-bit driver for the printer.
To resolve this issue, the technician should enable 32-bit drivers on the Print Server. This means that the technician should install and configure a 32-bit driver for the printer on the print server, in addition to the existing 64-bit driver. This way, the print server can support both 64-bit and 32-bit clients, and allow them to print to the same printer34.
To enable 32-bit drivers on a Windows Print Server, the technician can follow these steps4:
On the print server, open Control Panel and select Devices and Printers.
Right-click on the printer that needs a 32-bit driver and select Printer Properties.
Click on the Sharing tab and check the box that says Share this printer.
Click on Additional Drivers and check the box that says x86 (for 32-bit).
Click OK and follow the instructions to install and configure the 32-bit driver.
For more information about print servers, drivers, and compatibility issues, you can refer to the following web search results: What is a Print Server?, What is a Device Driver?, How to Install Additional Drivers for Shared Printers, How to Enable 32-Bit Drivers on Windows Server.
