220-1101 exam dumps: questions 201 to 300 of 471

Correct answer: A

• A. Correct.

  Correct. Older standalone DVD players can be more sensitive to marginal burns, lower-quality media, and discs written at high speeds. Burning at a slower supported speed often improves the quality of the recorded marks on the disc and increases readability in older optical drives. This is a practical first troubleshooting step when discs work in the source computer but not in less tolerant players.

• B. Incorrect.

  Incorrect. DVD-R discs are not prepared for video playback by formatting them to FAT32 like a flash drive. Video DVDs require proper authoring and finalization so the player can read the expected disc structure. FAT32 formatting is a common misconception based on removable USB storage, not optical video media.

• C. Incorrect.

  Incorrect. CD-R does not provide better compatibility for DVD video playback. Standard standalone DVD players are designed to read DVD video discs, and CD-R does not have the capacity needed for most DVD-quality video archives. Someone might choose this option by confusing general optical media compatibility with the specific DVD video format.

• D. Incorrect.

  Incorrect. Display resolution on the computer has no effect on the optical burn quality or whether a standalone DVD player can read the disc. This distractor targets the misconception that playback issues are related to how the video looked on the source PC rather than the recording quality and disc format.

Correct answer: A

• A. Correct.

  Correct. Single-mode fiber is designed for long-distance communication and supports high bandwidth over several kilometers by using a very small core that allows light to travel in a single path. This reduces modal dispersion, making it the best choice for a 6 km interbuilding connection.

• B. Incorrect.

  Incorrect. Multimode fiber is commonly used for shorter-distance runs within buildings or campuses, but it is not the best choice for a 6 km link. Because light travels along multiple paths in multimode fiber, modal dispersion increases over distance and limits its practical range compared with single-mode fiber.

• C. Incorrect.

  Incorrect. Cat 6 twisted-pair copper is typically limited to 100 meters for standard Ethernet runs. A 6 km connection is far beyond copper Ethernet distance limitations, so this option would not meet the requirement without additional active equipment.

• D. Incorrect.

  Incorrect. RG-6 coaxial cable is used for applications such as cable television, broadband modem connections, and some video distribution. It is not the standard or appropriate medium for a high-speed 6 km campus backbone network link.

Correct answer: A

• A. Correct.

  Correct. Multimode fiber is commonly used for shorter-distance backbone links within buildings and campuses. A 220-meter run between wiring closets is a realistic use case for multimode fiber, which is generally less expensive than single-mode optics for these shorter distances. On A+ Core 1, multimode is associated with shorter runs and LAN/backbone connections inside facilities.

• B. Incorrect.

  Incorrect. Single-mode fiber supports much longer distances and higher-bandwidth long-haul links, but it is typically chosen when the distance exceeds what multimode can efficiently support or when long-distance backbone connections are required. While it could work technically, it is not the most appropriate or cost-effective choice for this in-building 220-meter run.

• C. Incorrect.

  Incorrect. Cat 6 UTP Ethernet cabling has a maximum standard segment length of 100 meters for twisted-pair Ethernet runs. At 220 meters, this exceeds the supported distance and would not be appropriate without additional active equipment between segments.

• D. Incorrect.

  Incorrect. RG-6 coaxial cable is commonly associated with cable television, cable modems, and some broadband applications, not standard modern Ethernet backbone links between wiring closets. It is not the appropriate choice for this fiber-based inter-closet network upgrade.

Correct answer: A

• A. Correct.

  Correct. This scenario strongly suggests the current USB-C cable supports USB data and charging but not full Thunderbolt functionality. Thunderbolt 3 and 4 use the USB-C connector, but not every USB-C cable supports Thunderbolt signaling, high-bandwidth PCIe devices, or full video output capability. Replacing it with a certified Thunderbolt cable is the best next troubleshooting step because the dock partially works, indicating the dock and port may be functional while the cable is limiting features.

• B. Incorrect.

  Incorrect. Monitors connected through a Thunderbolt dock do not typically require a separate DisplayPort driver per monitor on the laptop. Video output through the dock depends more on the host port, dock capability, graphics support, and cable capability. A technician might choose this option because the symptom involves displays, but the missing SSD and working USB devices point to a transport or connectivity limitation rather than a monitor driver issue.

• C. Incorrect.

  Incorrect. A USB 3.2 Gen 2 dock would not be the best replacement for a Thunderbolt workflow that includes multiple displays and a high-speed external SSD. In fact, replacing the dock could reduce available bandwidth and features. The current symptoms are more consistent with using a non-Thunderbolt USB-C cable or another Thunderbolt path issue, not proof that the Thunderbolt dock itself is the wrong type.

• D. Incorrect.

  Incorrect. USB Power Delivery allows charging over the USB-C connection and is already functioning in this scenario. Disabling power delivery would not restore Thunderbolt data paths or video output. Someone might choose this option if they suspect a power negotiation problem, but the evidence shows power is working while higher-bandwidth functions are not.

Correct answer: D

• A. Incorrect.

  VGA is incorrect because it is an analog video standard and does not carry audio. It is also not the appropriate choice for a modern 4K 60 Hz digital display setup. A technician might choose VGA because the monitor supports it, but it would not meet the resolution, refresh rate, and audio requirements in this scenario.

• B. Incorrect.

  Single-link DVI-D is incorrect because it is a digital video connection but does not normally provide audio support for a monitor setup like HDMI or DisplayPort. In addition, single-link DVI does not provide enough bandwidth for 3840 x 2160 at 60 Hz. This distractor targets the misconception that any digital cable can handle all modern display requirements.

• C. Incorrect.

  HDMI is incorrect in this question because, although many HDMI versions can carry both digital video and audio, the scenario asks for the best choice without adapters and with assured 4K at 60 Hz capability. On A+ exam-style questions, DisplayPort is typically the preferred PC monitor connection for high-resolution computer displays when both the system and monitor support it directly. A technician might select HDMI because it is common and does carry audio, but DisplayPort is the more appropriate answer here.

• D. Correct.

  DisplayPort is correct because it is a digital video interface commonly used on PCs, supports high resolutions such as 3840 x 2160 at 60 Hz, and carries audio over the same cable. It also satisfies the requirement to avoid adapters because both the desktop and monitor have native DisplayPort ports. This makes it the best fit for a modern workstation-to-monitor connection.
