• Question 711:

  Which of the following cables should be used when connecting a cable modem to a SOHO router?

  A. FireWire
  B. Fiber
  C. Ethernet
  D. Coaxial
  C. Ethernet

  ---

  Explanation

  The correct answer is

  C. Ethernet. An Ethernet cable is a type of network cable that is used to connect devices on a local area network (LAN), such as computers, routers, switches, and modems. Ethernet cables have RJ-45 connectors at both ends, which are similar to telephone jacks but larger. Ethernet cables can carry data signals at speeds ranging from 10 Mbps to 10 Gbps, depending on the type and quality of the cable. A cable modem is a device that connects to a coaxial cable from a cable service provider and provides high-speed internet access. A SOHO router is a small office/home office router that connects to a cable modem or DSL modem and provides network and internet access to multiple devices on a LAN. A SOHO router typically has one WAN port and four LAN ports. The WAN port is used to connect to the cable modem or DSL modem, while the LAN ports are used to connect to computers or other devices on the LAN. To connect a cable modem to a SOHO router, an Ethernet cable is needed. The Ethernet cable is plugged into the WAN port of the SOHO router and the Ethernet port of the cable modem. This allows the SOHO router to receive an IP address from the cable service provider and share it with the devices on the LAN using network address translation (NAT). The SOHO router also provides firewall and wireless features for the LAN. The other options are incorrect because they are not suitable for connecting a cable modem to a SOHO router. FireWire is a type of serial bus that is used to connect devices such as digital cameras, external hard drives, and audio interfaces. FireWire cables have different connectors than Ethernet cables and cannot be used for network communication. Fiber is a type of optical cable that uses light signals to transmit data over long distances. Fiber cables have special connectors that are not compatible with Ethernet ports. Coaxial is a type of copper cable that has a central conductor surrounded by an insulating layer and a braided shield. Coaxial cables are used for cable TV and internet services, but they cannot be directly connected to Ethernet ports without an adapter.

• Question 712:

  A user sends a print job lo a network printer, and the print job uses double the amount of paper as expected. Which of the following should the user configure to get the expected result?

  A. Duplex
  B. Collate
  C. Landscape
  D. Transparency

• Question 713:

  A technician is preparing a redesigned conference room for a presentation. The presenter connects a laptop to the LCD projector, but a "No input source" error message is displayed on the LCD projector's screen. However, the presentation is working on the laptop's LCD screen when in mirroring mode on the docking station. Which of the following troubleshooting steps should the technician take first?

  A. Replace the LCD projector.
  B. Reboot the laptop.
  C. Update the display drivers.
  D. Check the physical cabling.
  D. Check the physical cabling.

  ---

  Explanation

  One of the possible causes of the error message "No input source" is that the LCD projector is not receiving any signal from the connected device, such as a laptop1. This could be due to a loose or faulty cable or connector, or an incorrect input source selected on the projector2. Therefore, the first troubleshooting step that the technician should take is to check the physical cabling and make sure it is properly connected and secured12.

• Question 717:

  A technician is adding one more line at the demarcation point. Which of the following tools would be MOST useful to accomplish this task?

  A. Toner
  B. Punchdown
  C. Network tap
  D. Crimper
  B. Punchdown

  ---

  Explanation

  Punchdown tools are used to connect wires to keystone jacks, patch panels and other communication hardware. When adding a new line at the demarcation point, a technician would use a punchdown tool to punch the wire into the keystone jack or patch panel, completing the connection.

• Question 718:

• Question 719:

  A user is looking for a way to increase the total RAM in a system without upgrading the hardware. Which of the following should the user perform to complete this task?

  A. Run a burn-in application
  B. Create a VM.
  C. Install hardware-tuning software.
  D. Set up virtual memory.
  D. Set up virtual memory.

  ---

  Explanation

  Virtual memory is a software-based memory management system that allows a computer to use hard disk storage space as RAM. This can be used to increase the total RAM in a system without upgrading the hardware. To set up virtual memory, the user should go to the System Properties window and select the Advanced tab. In the Performance section, click on the Settings button, which will open the Performance Options window. Then, click on the Advanced tab and click on the Change button in the Virtual memory section. Finally, select the option to Automatically manage paging file size for all drives, and then click OK to save the changes.

• Question 720:

  A user requested upgrades to a company-Issued laptop to increase its performance while working with a large database stored on drive

  C. Which of the following tasks should a systems administrator complete to BEST meet this goal? (Select TWO).

  A. Configure RAID 1.
  B. Install a hybrid drive.
  C. Upgrade to 1GB NIC.
  D. Increase the RAM.
  E. Migrate to a SSD.
  F. Upgrade the power supply.
  D. Increase the RAM.
  E. Migrate to a SSD.

  ---

  Explanation

  To increase the performance of a laptop working with a large database stored on drive C, a systems administrator should increase the RAM and migrate to an SSD. Increasing the RAM will help the laptop to better handle the large database,

  while migrating to an SSD will improve the speed at which the laptop can access the database. Configuring RAID 1, installing a hybrid drive, upgrading to a 1GB NIC, and upgrading the power supply will not directly improve the laptop's

  performance when working with a large database.
