質問 # 71
管理者はネットワーク サーバーの停止に対応しています。管理者は、停止のトラブルシューティングを行うためにサーバーにログインしました。問題のトラブルシューティングを行うときに管理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. サーバーのファームウェアをアップグレードします。
- B. 結果を文書化します。
- C. 物理的な接続を確認します。
- D. エラーログを解析します。
正解：D
解説：
Explanation
The correct answer is B. Analyze the error logs.
Error logs are files that record the events and errors that occur on a server or a network device. They can provide valuable information about the cause and the time of the outage, as well as any warnings or alerts that preceded it. Analyzing the error logs can help the administrator narrow down the possible sources of the problem and identify the best course of action to resolve it.
The first step in troubleshooting a network is to identify the problem1. As a part of this step, the administrator should gather information about the current state of the network using the network troubleshooting tools that are available1. One of these tools is the error log viewer, which can be accessed through the server's operating system or a network monitoring software. The administrator should look for any entries that indicate a failure, a crash, a timeout, or an exception in the error logs. The administrator should also note the date and time of the entries, as well as the severity and the frequency of the errors.
The other options are less likely to be the first step in troubleshooting, because:
*Documenting the results is an important step in troubleshooting, but it should be done after identifying and resolving the problem, not before. Documenting the results can help the administrator keep track of the actions taken, the changes made, and the outcomes achieved. It can also help prevent future problems by providing a reference for best practices and lessons learned1.
*Checking the physical connections is another important step in troubleshooting, but it should be done after analyzing the error logs, not before. Physical connections are the cables and ports that link the server to other devices on the network. They can affect the quality and stability of the network signal. If the error logs do not indicate any software or configuration issues, then checking the physical connections can help determine if there is any damage or interference in the hardware2.
*Upgrading the server firmware is a possible solution for some network problems, but it should not be done as a first step in troubleshooting, unless there is a clear indication that the firmware is outdated or corrupted.
Firmware is a type of software that controls the basic functions of a hardware device. Upgrading the firmware can improve performance, security, and compatibility, but it can also introduce new bugs or conflicts with other software or hardware components. Therefore, upgrading the firmware should be done with caution and only after backing up data and settings3.

質問 # 72
お客様から、ラップトップの下端にある一部のキーが押しにくく、トラック パッド ボタンをクリックするにはかなりの力が必要であるとの報告がありました。技術者はラップトップを検査しますが、シャーシや画面に亀裂やその他の損傷は見つかりませんでした。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. お客様がノートパソコンを落としてしまいました。
- B. バッテリーが膨れています。
- C. 開いた消毒用アルコールのボトルがキーボードの上に落ちました。
- D. デジタイザが故障しました。
正解：B
解説：
A swollen battery is the most likely cause of the issue that the customer is reporting. A swollen battery is a battery that has expanded in size due to a chemical reaction, gas buildup, or overheating. A swollen battery can cause pressure on the laptop's chassis, keyboard, track pad, and other components, making them hard to press or click. A swollen battery can also pose a fire hazard and damage the laptop's performance and lifespan.
The other options are not as likely or relevant to the issue. Dropping the laptop may cause cracks or other visible damage to the chassis or screen, but the technician did not notice any. The digitizer is the part of the laptop that converts touch input into digital signals, and it has nothing to do with the keyboard or the track pad buttons. An open bottle of rubbing alcohol falling onto the keyboard may cause liquid damage, corrosion, or short circuits, but it would not affect the track pad buttons or the bottom edge of the keyboard.
To troubleshoot and resolve the issue, the technician should remove the battery from the laptop and inspect it for signs of swelling, such as bulging, deformation, or leakage. The technician should also check the laptop's chassis, keyboard, and track pad for any signs of damage or warping caused by the battery. The technician should then replace the swollen battery with a new one that is compatible with the laptop's model and specifications. The technician should also dispose of the swollen battery properly and safely, following the local regulations and guidelines.

質問 # 73
管理者は、RJ45 コネクタを使用してネットワーク ケーブルを終端しています。管理者が終端しているのは次のケーブルのうちどれですか?
- A. シリアル
- B. カテゴリー6
- C. 光学式
- D. USB
正解：B
解説：
The correct answer is C. Cat 6.
An RJ45 connector is a standard type of physical connector for network cables. RJ45 connectors are used almost exclusively with Ethernet cables and networking1. Ethernet cables are twisted pair cables that carry data signals between devices on a network, such as computers, routers, switches, and servers2.
There are different categories of Ethernet cables, such as Cat 5, Cat 5e, Cat 6, and Cat 7, that have different specifications and performance levels. Cat 6 is one of the most common types of Ethernet cables, which supports data transfer speeds up to 10 Gbps and bandwidth up to 250 MHz3. Cat 6 cables have four pairs of copper wires, each with a plastic insulation and a foil or braided shield. The wires are twisted together to reduce crosstalk and interference4.
To terminate a Cat 6 cable, an administrator needs to use an RJ45 connector that matches the wiring scheme of the cable. There are two common wiring schemes for Ethernet cables: T568A and T568B. The administrator needs to strip the cable jacket, untwist the wires, arrange them in the correct order according to the chosen scheme, trim the excess wire, and insert them into the RJ45 connector. Then, the administrator needs to use a crimping tool to secure the wires and the connector4.
Optical cables are not terminated with RJ45 connectors, but with different types of connectors that can transmit light signals, such as SC, ST, LC, or MTRJ connectors. Optical cables are used for fiber-optic networks that can carry data over long distances at high speeds.
Serial cables are not terminated with RJ45 connectors, but with different types of connectors that can transmit serial data signals, such as DB9, DB25, or DE9 connectors. Serial cables are used for connecting devices that use serial communication protocols, such as modems, printers, scanners, or keyboards.
USB cables are not terminated with RJ45 connectors, but with different types of connectors that can transmit universal serial bus data signals, such as USB-A, USB-B, USB-C, or Micro-USB connectors. USB cables are used for connecting devices that use USB communication protocols, such as flash drives, cameras, mice, or chargers.

Bluetooth デバイスとスマートフォンのペアリングに使用されるネットワーク タイプは次のどれですか?
- A. PAN
- B. WAN
- C. MAN
- D. LAN
正解：A
解説：
Explanation
A PAN, or Personal Area Network, is the network type that is used for pairing a Bluetooth device to a smartphone. A PAN is a network that connects personal devices, such as phones, tablets, laptops, headphones, speakers, or printers, over a short distance, usually less than 10 meters or 33 feet. A PAN can use wireless technologies, such as Bluetooth, Wi-Fi, or infrared, to enable communication and data exchange between the devices. A Bluetooth PAN, also known as a piconet, can consist of up to eight devices, one of which acts as the master and the others as slaves. The master device initiates the pairing process with the other devices and controls the data transmission. The devices use radio waves in the 2.4 GHz frequency band to communicate with each other. Bluetooth is a low-power, low-cost, and secure technology that is widely used for creating PANs.

質問 # 76
アプリケーション開発者は、すべてのアプリケーション テストが完了した後、開発 PC をフォーマットして再構成します。このプロセスの効率を向上させる最善の方法は次のうちどれですか?
- A. SSD の取り付け
- B. ハードウェア アクセラレーションを有効にする
- C. サンドボックスの実装
- D. ハイパースレッディングを無効にする
正解：C
解説：
The best way to improve the efficiency of the process of formatting and reconfiguring a development PC after every application test is complete is to implement a sandbox. A sandbox is a virtual environment that isolates the application from the rest of the system, allowing the developer to test the application without affecting the main operating system, files, or settings. A sandbox can also be easily reset, deleted, or duplicated, saving the time and effort of formatting and reconfiguring the PC. A sandbox can also provide security benefits, such as preventing malware or bugs from spreading to the system or the network.
Other options, such as installing an SSD, disabling hyperthreading, or enabling hardware acceleration, may improve the performance of the PC, but they do not address the issue of formatting and reconfiguring the PC after each test. An SSD (solid state drive) is a storage device that uses flash memory instead of spinning disks, and it can offer faster data access, lower power consumption, and less noise and heat. Hyperthreading is a feature of some CPUs (central processing units) that allows each core to run two threads simultaneously, increasing the multitasking and parallel processing capabilities of the PC. Hardware acceleration is a technique that uses the GPU (graphics processing unit) or other specialized hardware to perform some tasks faster than the CPU, such as rendering graphics, video, or audio.

正解：
解説：
Explanation
Based on the requirements, the best option for the video-editing workstation is to use RAID 10 with four SATA SSDs of 1TB each. This configuration will meet the following requirements:
Be able to edit files at the fastest speed: RAID 10 combines the advantages of RAID 0 and RAID 1, which are striping and mirroring, respectively. Striping can increase the data transfer rate by using multiple disks in parallel, while mirroring can provide redundancy and reliability by duplicating the data on another set of disks. SATA SSDs are also faster than HDDs or SSHDs, as they use flash memory instead of spinning disks, and they can offer lower latency, higher IOPS, and less noise and heat.
Allow for disk failure without any downtime: RAID 10 can withstand up to two disk failures, as long as they are not in the same mirrored pair. If one disk fails, the data can be read from or written to the other disk in the same pair, without affecting the performance or availability of the array. The failed disk can be replaced and rebuilt without interrupting the operation of the workstation.
Have 2TB of usable space: RAID 10 uses half of the total disk capacity for mirroring, so the usable space is equal to the size of two disks. By using four SATA SSDs of 1TB each, the total disk capacity is
4TB, and the usable space is 2TB, which meets the requirement.
Ensure the most robust fault tolerance: RAID 10 offers the highest level of fault tolerance among the standard RAID levels, as it can survive multiple disk failures and provide fast recovery. RAID 10 also has a low overhead, as it does not use parity or checksums, which can slow down the write performance or increase the complexity of the array.
Therefore, the technician should select the following options from the drop-down menus:
RAID level: RAID 10
Drive type 1: SATA SSD
Drive size 1: 1TB
Drive type 2: SATA SSD
Drive size 2: 1TB
Drive type 3: SATA SSD
Drive size 3: 1TB
Drive type 4: SATA SSD
Drive size 4: 1TB
Drive type 5: SATA SSD
Drive size 5: 1TB

次のデバイスのうち、最も適切なものはどれですか?
- A. NAS
- B. SAN
- C. HDD
- D. SSD
正解：D
解説：
Explanation
An SSD (solid state drive) is a removable storage device that uses flash memory to store data. It is secure, portable, and does not contain moving parts, which makes it more reliable and durable than other types of storage devices. An HDD (hard disk drive) is not suitable, as it contains spinning platters and read/write heads that are prone to damage and data loss. A NAS (network attached storage) and a SAN (storage area network) are not removable devices, as they are connected to a network and provide shared storage for multiple users.
