[ap12_801_1-5.exm APESS_5-2 #7] Question 6: Correct Question 7: Correct Question 8: Correct Question 9: Correct Question 10: Incorrect You're configuring devices on a SCSI bus. You've installed a SCSI adapter in an expansion slot. You've connected an external SCSI tape drive to the external port connector on the adapter. You've connected two hard SCSI hard disk drives (sd0 and sd1) to two of the middle connectors on the internal SCSI ribbon cable. The end connector on the internal SCSI ribbon cable is connected to a SCSI DVD drive. Where should termination be enabled on this bus? (Choose two.) On hard drive sd0. On hard drive sd1. On either hard disk drive. On the DVD drive. On the external tape drive. On the SCSI adapter. Explanation Because the external tape drive and the DVD drive are attached to the two ends of the SCSI bus, both of these devices need to have termination enabled. No device in between these two devices, including the SCSI adapter, should have termination enabled. Enabling termination on any of these devices could potential cause devices farther down the bus to not be recognized by the controller. References LabSim for PC Pro, Section 5.5.

[ap12_801_1-7.exm APESS_4-2 MULTIPLE CHOICE [189]] Question 51: Correct Question 52: Incorrect You want to be able to watch live TV on your computer and record TV shows from over-the-air digital television stations. Your computer already has a video card, so you want to purchase an add-on card to provide the TV tuner input capabilities. Which of the following should be part of the configuration process? (Select two.) Purchase a card that supports ATSC. Connect the TV input to the tuner card using coaxial cable and F-type connectors. Link the TV tuner card to the video card using a bridge clip. Connect the TV input to the tuner card using the DMS-59 connector. Purchase a card that supports NTSC. Explanation A TV tuner allows your video card to accept a cable TV input and change channels from within the computer. NTSC, PAL, and SECAM are analog TV signal standards. NTSC was used in North America but is being phased out. ATSC signals are digital TV signals. When purchasing a new TV tuner, make sure it supports ATSC. Video cards and monitors with a built-in TV tuner have an Ftype cable TV connector used for connecting coaxial cable. The DMS-59 connector is used to about:blank Page 8 of 34 6/17/16, 12:11 AM allow multiple video ports from a single connection. The DMS-59 connector uses a special cable that splits the signal into separate video interfaces. For example, the cable might split the signal into two DVI-I connectors, two D-sub connectors, or one DVI-I connector and one D-sub connector. You do not need to link the TV tuner card to the video card (the TV tuner is used for input, while the video card is used for output). When using Crossfire or SLI, you might need to connect two video cards using a special bridge clip. Depending on the implementation, you might also use software to link the cards together.

Hot-swappable AT attachment about:blank Page 9 of 34 6/17/16, 12:11 AM Hot-play Plug-and-Play Explanation Inserting and removing PC cards without rebooting the computer is called hot-swapping. This feature is also called dynamic reconfiguration. Plug-and-Play devices are automatically detected by the system and the driver is automatically loaded. Unless the bus and the device is hotswappable, Plug-and-Play devices should be added or removed with the system shut down. AT Attachment (ATA) is the standard interface for transferring data from storage devices such as hard disk drives and optical drives. References LabSim for PC Pro, Section 4.6. [ap12_801_1-4.exm APESS_4-7 MCS45 [7]] Question 63: Correct Question 64: Incorrect What is the major difference between the BTX and the ATX standards? (Select two.) Improved thermal management. Reduced emissions from using integrated I/O connectors. Processor slot rotated 45 degrees. Smaller case. Ability to mount the motherboard so it can slide in or out of the system case easily. Explanation The BTX form factor was designed to improve thermal management and enhance compatibility with new styles and components. The BTX form factor's case was more accommodating, but not smaller. The ability to mount the motherboard so it can slide in or out of the system case easily was a feature of the NLX. Reduced emissions from using integrated I/O connectors was a feature of the Micro-ATX. References LabSim for PC Pro, Section 3.1. [ap12_801_1-2.exm APESS_3-1 MULTIPLE CHOICE [611]] Question 65: Correct Question 66: Correct Question 67: Correct Question 68: Correct Question 69: Correct Question 70: Correct about:blank Page 10 of 34 6/17/16, 12:11 AM Question 71: Correct Question 72: Incorrect Which RAID configuration level provides increased performance using only two disks? RAID 5 RAID 0 RAID 1 RAID 2 Explanation RAID 0 (striping) uses two or more disks and provides an increase in performance but not fault tolerance. RAID 1 (mirroring) uses two disks to provide fault tolerance but not an increase in performance. RAID 5 uses a minimum of three disks and provides both fault tolerance and an increase in read performance. References LabSim for PC Pro, Section 5.8. [ap12_801_1-5.exm APPA_4-4 D4] Question 73: Incorrect A system board has four 32-bit RIMM slots. You have installed one RIMM. Which of the following are correct? (Select two.) You can complete the installation by installing three continuity modules. You can complete the installation by installing three more RIMMs. You have properly installed the RIMMs. You can complete the installation by installing one more RIMM to make a pair. Explanation When installing RIMMs, all RIMM slots must be filled either with a RIMM or a continuity module. 32-bit RIMMS can be installed as single units; 16-bit RIMMs must be installed in pairs. References LabSim for PC Pro, Section 3.5. [ap12_801_1-3.exm APPA_2-5 MCM42 [56]] Question 74: Correct Question 75: Correct Question 76: Incorrect You have an existing computer running Windows 7 Enterprise. You want to configure a RAID1 array in the computer. You install two new SATA drives, then use the RAID controller integrated in the motherboard to define a RAID1 array using them. When you boot the computer, Windows about:blank Page 11 of 34 6/17/16, 12:11 AM does not show the logical RAID drive. What should you do? Set the jumpers on the drives to use SATA I mode. Install the drivers for the RAID controller. In the BIOS, change the SATA disk mode to AHCI. In the BIOS, change the SATA disk mode to RAID. Explanation You must install the RAID driver so that Windows recognizes arrays created by the motherboard RAID utility. Without the driver, Windows will not be able to see the logical drive defined by the array. When you define the array, you configure the BIOS to use RAID as the SATA type. If you had not completed this step, you would not be able to run the RAID configuration utility. Use AHCI to configure SATA drives to support hot-swapping. References LabSim for PC Pro, Section 5.8. [ap12_801_1-5.exm APPA_4-4 D10] Question 77: Correct Question 78: Incorrect Which of the following statements are true about the DisplayPort interface for connecting video monitors to computers? (Select two.) DisplayPort carries both analog and digital signals. DisplayPort uses a lower voltage than DVI or HDMI. DisplayPort is electrically equivalent to DVI and HDMI. DisplayPort can send both video and audio signals over the same cable. Explanation DisplayPort is an alternative to an HDMI connector. DisplayPort uses a different signal format than DVI or HDMI. However, DisplayPort supports sending DVI or HDMI signals over the same port using a simple adapter. DisplayPort uses a digital-only signal. To connect a VGA monitor to a DisplayPort, you will need a special active converter that reformats the signal for analog devices. Like HDMI, DisplayPort can send audio signals over the same cable (if audio is supported by the video card and monitor). DisplayPort uses lower voltage than DVI and HDMI.
