A technician is working to connect an RS-232 serial signature pad to a customer's ultra light weight laptop. Which of the following should the technician use to install the device?
A. Port replicator
B. Wi-Fi Direct
C. Hotspot
D. USB-C cable
Correct Answer: D
A USB-C cable is the best option for installing an RS-232 serial signature pad to an ultralightweight laptop. USB-C is a universal connector that supports various protocols and devices, including serial devices. A port replicator is a device that expands the connectivity options of a laptop by providing additional ports. Wi-Fi Direct is a wireless technology that allows devices to connect directly without a router or access point. Hotspot is a feature that allows a device to share its internet connection with other devices via Wi- Fi, Bluetooth, or USB.
Question 62:
A user's Windows computer started running slowly after the installation of a CAD program. The computer has intermittent timeouts and often has to be rebooted to restore functionally. The computer seems to work correctly if the application is not running. Which of the following should the technician do NEXT to help troubleshoot the issue? (Select TWO).
A. Replace the video card.
B. Research the requirements of the application.
C. Install a new case fun.
D. Run chkdsk on the HDD.
E. Check the Event Viewer logs.
F. Reinstall the application.
Correct Answer: BE
The technician should research the requirements of the CAD program to see if the computer meets them or needs any upgrades or updates to run it properly. The technician should also check the Event Viewer logs to see if there are any
errors or warnings related to the application or system performance that could indicate the cause of the problem or suggest a solution.
A field technician for an airport receives a support ticket that states customers are having issues viewing a screen that displays information about departing flights. While checking the case history, the technician sees that all flight information screens were recently moved when the terminal gates were remodeled. Which of the following actions should the technician perform after verifying the screen has power?
A. Ensure the input connections to the screen are secure.
B. Swap cables with a screen that works.
C. Check to see if the device outputting the data is turned on.
D. Determine if the screen is compatible with the output device.
Correct Answer: A
The technician should ensure the input connections to the screen are secure
1. The screen may not be receiving the signal from the device outputting the data if the input connections are not secure1. Swapping cables with a screen that works is not likely to be the correct option1
Question 64:
Which of the following network options would work BEST to ensure a client-side virtual machine cannot access the rest of the network?
A. NAT mode
B. Bridge mode
C. Direct mode
D. Host-only mode
Correct Answer: D
Host-only mode is a network option that isolates a client-side virtual machine from the rest of the network. It allows the virtual machine to communicate only with the host machine and other virtual machines on the same host. NAT mode allows the virtual machine to share the host's IP address and access the network through it. Bridge mode allows the virtual machine to have its own IP address and connect directly to the network. Direct mode is not a valid network option for virtual machines.
Question 65:
Users report that all copies produced on a copter have a solid black line, but printing is unaffected. Which of the following is the MOST likely cause?
A. Failing imaging drum
B. A scratch on the scanning bed
C. Bad output tray
D. Damaged (user
Correct Answer: B
A scratch on the scanning bed of a copier can cause a solid black line to appear on all copies, as the scanner cannot read the original document properly through the scratch. The scratch can also reflect light and create noise in the scanned
image. The printing function is unaffected by the scratch, as it does not use the scanning bed. The technician should inspect and clean the scanning bed, and replace it if necessary.
A technician is troubleshooting connectivity issues and needs to promiscuously route a copy of traffic to a separate machine for analysis. Which of the following physical tools v/ould BEST accomplish this task?
A. Toner probe
B. Wi-Fi analyzer
C. Network tap
D. Loopbackplug
Correct Answer: C
A network tap is a physical device that allows promiscuous monitoring of network traffic by creating a copy of the data packets for analysis. A toner probe is used to trace and identify cables. A Wi-Fi analyzer is used to measure wireless signal strength and interference. A loopback plug is used to test network ports or cables by sending and receiving signals from the same device.
Question 67:
A user built a new PC with parts sourced torn a popular online vendor. The system boots to the OS and basic browsing works, but whenever the user opens a 4K video or starts to play a game, the system Immediately shuts down. Which of the following is the MOST likely cause of this issue?
A. The video card was Installed in the wrong PCIe slot.
B. The CPU heat sink was attached without adequate thermal paste.
C. The SSD drives do not have enough Pagefile.
D. The system does not have enough RAM tor 4K video.
Correct Answer: B
Thermal paste is a substance that fills in any gaps between a CPU and its heat sink, which is a device that dissipates heat from the CPU. Without adequate thermal paste, the CPU may overheat and cause the system to shut down
automatically to prevent damage. This is especially likely when running 4K video or games, which are more demanding and generate more heat. The technician should check if the CPU heat sink was attached properly and apply enough
thermal paste to ensure good contact and heat transfer.
Which of the following network devices operates as a bridge function?
A. Hub
B. Wireless access point
C. Transceiver
D. Media converter
Correct Answer: D
A media converter is a network device that operates as a bridge function, which means it connects two different types of network media, such as copper and fiber optic cables, and converts signals between them. This allows network devices
that use different media types to communicate with each other over long distances or in different environments, without requiring major changes or upgrades to the existing network infrastructure.
Which of the following BEST describes a lab environment in which virtual machines can be created, rebooted, and shut down without affecting the production network?
A. SCADA
B. Sandbox
C. Honeypot
D. Hybrid cloud
Correct Answer: B
A sandbox is a lab environment in which virtual machines can be created, rebooted, and shut down without affecting the production network. This allows for testing and experimentation without the risk of damaging the production environment123..
Question 70:
Which of the following video cables can carry an audio signal?
A. HDMI
B. S-Video
C. VGA
D. DVI
Correct Answer: A
This is because HDMI (High-Definition Multimedia Interface) is a digital video cable that can also carry audio signals1. HDMI cables are commonly used to connect devices like Blu-ray players, game consoles, and streaming boxes to HDTVs and monitors. The other options are not capable of carrying audio signals. VGA (Video Graphics Array) is an analog video cable that only carries RGBHV signals12. S-Video (Super Video) is another analog video cable that carries separate luminance and chrominance signals1 . DVI (Digital Visual Interface) is a digital video cable that can carry either analog or digital signals, but not audio1.
