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.

正解：

解説：
See the detailed solution in explanation below.
Explanation:
The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.
Recommended Replacement Drive:
To minimize performance degradation, the replacement drive should be:
SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).
Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.
In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.
A user reports poor performance on the
application server.
INSTRUCTIONS

  • B. 問題を解決するための行動計画を策定し、解決策を実行します。
  • C. 症状に基づいて外部または内部の調査を実施します。
  • D. 環境またはインフラストラクチャの変化について問い合わせます。

正解：C

解説：
According to the CompTIA troubleshooting methodology, the next step after establishing a theory of probable cause is to test the theory to determine the cause. However, before testing the theory, the technician may need to conduct some research based on the symptoms and the possible cause. This may involve consulting online resources, manuals, documentation, or colleagues to find out more information about the power supply and how to test it. Research can help the technician confirm or eliminate the theory and avoid unnecessary actions or damage.
Answer A is incorrect because inquiring about environmental or infrastructure changes is part of identifying the problem, which is the first step of the troubleshooting methodology. The technician should have already done this before establishing a theory of probable cause.
Answer C is incorrect because establishing a plan of action to resolve the problem and implement the solution is the fourth step of the troubleshooting methodology. The technician should not jump to this step without testing the theory and verifying the cause.
Answer D is incorrect because documenting the findings, actions, and outcomes is the last step of the troubleshooting methodology. The technician should not do this until the problem is resolved and verified.
Reference: Troubleshooting Methodology | IT Support and Help Desk | CompTIA The technician thinks the power supply is defective, indicating an initial hypothesis but not a confirmed diagnosis. According to the CompTIA A+ Core 1 Study Guide, troubleshooting follows a structured methodology (Objective 5.5: "Given a scenario, troubleshoot problems related to motherboards, RAM, CPU, and power"). At this stage, the technician has likely identified the problem (PC failure) and gathered basic information (suspected power supply issue). The next step is to refine the theory by conducting research based on symptoms-such as checking for common power supply failure signs (e.g., no power, burning smell, or intermittent shutdowns)-before proceeding to action or documentation.
B: Conduct external or internal research based on symptoms: This involves verifying the hypothesis by reviewing symptoms against known power supply failure patterns, possibly consulting manuals, online resources, or past experiences. It ensures the technician's suspicion is grounded in evidence before proceeding.
A: Inquire about environmental or infrastructure changes: This is part of initial information gathering, typically done before forming a hypothesis, not after suspecting a specific component.
C: Establish a plan of action and implement the solution: Premature without confirming the power supply is the issue; action comes after testing the theory.
D: Document findings, actions, and outcomes: Documentation occurs after resolving the issue, not at this intermediate stage.
The study guide's troubleshooting steps prioritize research and theory validation after identifying a potential cause, making B the next logical step.
From The Official CompTIA A+ Core 1 Study Guide (220-1101):
Section 5.5, Troubleshooting Methodology:
"1. Identify the problem... Gather information from the user, identify user changes, and perform backups if applicable."
"2. Establish a theory of probable cause (question the obvious)... Conduct external or internal research based on symptoms to refine your theory."
"3. Test the theory to determine cause... Once confirmed, move to planning and action."
"4. Establish a plan of action to resolve the problem and implement the solution."
"5. Verify full system functionality..."
"6. Document findings, actions, and outcomes."
Implication: After suspecting a power supply failure (step 1), the technician moves to step 2-researching symptoms-before testing or acting.
Section 5.5, Power Supply Issues:
"Power supply failure symptoms-No power, system won't boot, intermittent shutdowns, or a burning smell... Research common indicators online or in documentation to confirm the issue before replacing components." These excerpts show that researching symptoms follows the initial hypothesis and precedes actionable steps, aligning with option B.
Additional Reasoning:
Current Stage: The technician has a theory ("defective power supply") but hasn't confirmed it. Research bridges the gap between suspicion and certainty.
Power Supply Symptoms: Symptoms like no power or random reboots need validation-e.g., checking if fans spin or if there's a capacitor failure-which research can guide.
CompTIA Methodology: The six-step process is sequential. Step 1 (identify problem) is done; step 2 (establish and research theory) is next, not jumping to action (step 4) or documentation (step 6).
Other Options:
A: Asking about changes (e.g., power surges) is part of step 1, likely already done to suspect the power supply.
C: Planning and implementing (e.g., replacing the PSU) requires a tested theory, not just a suspicion.
D: Documentation is the final step, not the next one after forming a hypothesis.

質問 # 324
ユーザーが 3D プリンターで熱可塑性ポリウレタン (TPU) フィラメントを使用して部品を印刷しています。すべての印刷ジョブの最初のレイヤーが適切に接着されていません。
最初の層の密着性を向上させるためにユーザーが行うべきことは次のうちどれですか?

  • A. 印刷速度を上げます。
  • B. フィラメント流量を上げます。
  • C. 冷却ファンの回転数を調整します。
  • D. プリントベッド温度を下げます。

正解：B

解説：
Explanation
The correct answer is D. Raise the filament flow amount.
Filament flow amount, also known as extrusion multiplier or flow rate, is the setting that controls how much filament is extruded by the nozzle during 3D printing. It is usually expressed as a percentage of the default value, which is 100%. Increasing the filament flow amount means extruding more filament than usual, while decreasing it means extruding less1.
The filament flow amount can affect the quality and adhesion of the first layer, which is crucial for a successful 3D print. If the filament flow amount is too low, the nozzle may not extrude enough filament to fill the gaps between the lines and create a smooth and solid first layer. This can result in poor adhesion, curling, warping, or detachment of the print from the bed12.
To improve adherence on the first layer, the user should raise the filament flow amount slightly, such as 105% or 110%, to ensure that enough filament is extruded to create a strong bond with the bed. The user should also make sure that the nozzle height, bed leveling, and bed temperature are properly calibrated for optimal first layer adhesion12.
The other options are less likely to improve adherence on the first layer, because:
*Lowering the print bed temperature may reduce the adhesion of the TPU filament to the bed, as TPU usually requires a bed temperature between 20-60°C for the best results3. Lowering the bed temperature may also increase the risk of warping or curling of the print4.
*Adjusting the RPM of the cooling fan may not have a significant effect on the first layer adhesion, as cooling fans are not required with TPU3. In fact, using a cooling fan with TPU may cause cracking or delamination of the print, as TPU needs to cool down slowly and evenly4.
*Increasing the print speed may worsen the first layer adhesion, as TPU is a flexible and elastic filament that needs to be printed slowly and consistently. A recommended print speed for TPU is 15-30mm/s3. Increasing the print speed may cause clogging, stringing, blobs, or under-extrusion of the filament4.

質問 # 325
技術者が顧客のラップトップの Wi-Fi 接続の問題のトラブルシューティングを行っています。ラップトップは接続しますが、断続的に切断されます。技術者は、ワイヤレス カードが正しく取り付けられており、ルーターの設定が正しく、ワイヤレス信号の強度が正常であることをすでに確認しています。技術者が次に調査すべきものは次のうちどれですか?

  • A. 無線周波数
  • B. ファイアウォールの設定
  • C. 接続されているデバイスの数
  • D. MACアドレスフィルター

正解：A

解説：
The next thing that the technician should investigate is D. Radio frequency.
Radio frequency is the range of electromagnetic waves that are used to transmit wireless signals. Different devices and networks use different radio frequencies, such as 2.4 GHz or 5 GHz, to communicate with each other. If there are multiple devices or networks using the same or overlapping radio frequencies, they can interfere with each other and cause Wi-Fi connection issues, such as intermittent disconnections, slow speeds, or poor quality .
To fix this issue, the technician can try changing the radio frequency or channel of the router or the laptop, to avoid interference from other sources. The technician can also use a tool such as Wi-Fi Analyzer to scan the nearby wireless networks and find the best frequency or channel to use. Alternatively, the technician can move the router or the laptop to a different location, away from potential sources of interference, such as cordless phones, microwaves, Bluetooth devices, or other routers .
The other options are less likely to be the reason for the issue. Firewall settings are software configurations that control the network traffic and security of a device. They may block some websites or applications from accessing the internet, but they should not affect the Wi-Fi connection itself. MAC address filter is a feature that allows the router to restrict access to specific devices based on their MAC addresses, which are unique identifiers for network interfaces. If the MAC address filter is enabled and the laptop's MAC address is not on the allowed list, it will not be able to connect to the Wi-Fi network at all, not intermittently. Number of connected devices is the amount of devices that are using the same Wi-Fi network at the same time. This may affect the network performance or bandwidth, but it should not cause intermittent disconnections, unless the network is overloaded or unstable.

質問 # 331
技術者が RAID 5 アレイ内の故障したドライブを交換しています。アレイからドライブをホットスワップする前に技術者が最初に実行する必要がある手順は次のうちどれですか。

  • A. 交換日を記録します。
  • B. アレイをシャットダウンする_
  • C. 故障したドライブを安全に処分します。
  • D. 完全バックアップを実行する

正解：D

解説：
The answer is D. Perform a full backup.
Before replacing a failed drive in a RAID 5 array, the technician should perform a full backup of the data on the array to ensure that no data is lost during the hot swapping process. Hot swapping is the process of replacing a drive without shutting down the system or the array, which allows for faster recovery and minimal downtime. However, hot swapping also involves some risks, such as accidentally removing the wrong drive, damaging the new drive, or encountering another drive failure during the rebuild process. Therefore, performing a full backup is a precautionary measure that can prevent data loss in case of any unexpected errors or complications.
The other options are not the first steps that the technician should take before hot swapping the drive. Documenting the replacement date is a good practice, but it is not as important as backing up the dat a) Shutting down the array is not necessary for hot swapping, and it may cause more disruption to the system or the users. Safely disposing of the failed drive is a step that should be done after replacing it, not before.
Reference:
Hot-swapping the hard drives when the RAID crashes | QNAP, section "Install a new drive to rebuild RAID 5 by hot swapping": "Important: Do not install a new drive when the system is not in degraded mode, otherwise you may encounter unexpected system failures." Hot Swapping hard drives on Raid 5 with data on them - Spiceworks Community, reply by Magnus369: "Part of that slowness would be the raid level you are using. Highly doubt you can change it without losing data either, but your writes are going to be atrociously slow due to having to figure out parity across 11 drives for each write you do. While you may have a ton of space, it's unstable and subject to self destruction." hard drive - How do I Change a damaged Disk in a Raid 5 array - Server Fault, answer by Chris S: "If you have another disk failure during rebuild you will lose all your data."

ユーザーの問題の原因として最も考えられるのは次のうちどれですか?

  • A. ネットワークケーブルが不良です
  • B. IPアドレスが間違っています
  • C. デフォルト ゲートウェイの構成が間違っています
  • D. NIC の故障

正解：D

解説：
Based on the information recorded by the technician, the network connection appears to be functioning normally. The user's computer is properly configured with an IPv4 address, subnet mask, and default gateway, which should allow the user to access the internet and online videos. The high download and upload speeds and low ping time recorded from the test laptop also indicate that the network is working well. However, the user's inability to watch online videos suggests that there might be an issue with the network card (NIC) on the user's computer. The NIC might be faulty or malfunctioning, which is preventing the computer from receiving and processing the video data. The technician should try replacing the NIC to resolve the issue.


質問 # 333
