質問 # 221
Users are able to connect to the wireless network, but they are unable to access the internet. The network administrator verifies connectivity to all network devices, and there are no ISP outages. The server administrator removes the old address leases from the active leases pool, which allows users to access the internet. Which of the following is most likely causing the internet issue?
- A. THe DHCP exclusion needs to be removed.
- B. The DHCP reservations need to be configured.
- C. The DHCP scope options are misconfigured.
- D. The DHCP lease times are too short.
- E. The DHCP scope is full.
正解：E
解説：
The most likely cause of the internet issue is B. The DHCP scope is full.
A DHCP scope is a range of IP addresses that a DHCP server can assign to DHCP clients on a network. A DHCP scope has a start address and an end address, and it can also have some excluded addresses that are not available for lease. A DHCP scope can have various options, such as subnet mask, default gateway, DNS server, etc., that are applied to the DHCP clients along with the IP address. A DHCP scope also has a lease time, which is the duration that a DHCP client can use an IP address before renewing it or releasing it. A DHCP scope can have reservations, which are fixed IP addresses that are assigned to specific DHCP clients based on their MAC addresses12 If a DHCP scope is full, it means that there are no more IP addresses available for lease in the scope. This can happen if the number of DHCP clients exceeds the number of IP addresses in the scope, or if the lease time is too long and the IP addresses are not released or reused frequently enough. If a DHCP scope is full, any new or existing DHCP clients that request an IP address from the DHCP server will not receive one, and they will not be able to access the network or the internet12 In this scenario, users are able to connect to the wireless network, but they are unable to access the internet. The network administrator verifies connectivity to all network devices, and there are no ISP outages. The server administrator removes the old address leases from the active leases pool, which allows users to access the internet. This indicates that the DHCP scope is full, and that removing the old leases frees up some IP addresses for lease in the scope. Therefore, option B is the most likely cause of the internet issue.
質問 # 222
ある企業は、アプリケーションの開発とテストのセキュリティとプライバシーの要件を満たすクラウド モデルを実装しています。この会社はコストを節約するために独自のハードウェアを使用したいと考えています。次のクラウド モデルのどれを展開する必要がありますか?
- A. プライベート
- B. コミュニティ
- C. ハイブリッド
- D. パブリック
正解：A
解説：
A Private Cloud is a cloud computing model where the infrastructure is dedicated solely to a single organization. This model offers enhanced security and privacy, as all resources are behind the organization's firewall and exclusively managed by the organization. By utilizing their own hardware, the company can control costs and tailor the environment to meet specific security and compliance requirements, making it ideal for application development and testing.
Other Options:
* A. Public: In a public cloud, services are delivered over the public internet and shared among multiple organizations. While cost-effective, it offers less control over security and privacy, which may not align with the company's requirements.
* B. Community: This cloud model is shared among several organizations with similar interests and requirements. Although it provides more control than a public cloud, it still involves shared resources, which may not meet the company's strict security and privacy needs.
* C. Hybrid: A hybrid cloud combines elements of both private and public clouds, allowing data and applications to be shared between them. While it offers flexibility, managing security and privacy across different infrastructures can be complex and may not provide the level of control the company desires.
Therefore, deploying a Private Cloud allows the company to utilize its own hardware, ensuring cost savings while meeting stringent security and privacy requirements for application development and testing.

質問 # 223
管理者は、サーバーがオフラインになっていることに気付きました。コンソールを確認すると、管理者はサーバーが次の状態で停止していることを発見しました。
メモリの設定.............
再起動後も、サーバーは同じ動作を示します。管理者は OOB リモート管理にログインできますが、サーバーにログインできません。この問題の原因として最も可能性が高いのは次のどれですか?
- A. DIMM に障害が発生しました
- B. BIOSを更新する必要があります
- C. RAIDキャッシュに障害が発生しました
- D. VRAMが不足しています
正解：A
解説：
The error message "Configuring Memory..." and the fact that the server is stuck at this point strongly suggest that a DIMM (memory module) has failed. Memory issues are commonly diagnosed when servers hang during the memory configuration phase of boot.
* DIMM failure (Answer A): When a memory module fails, the server can get stuck at the memory initialization process during boot.
* VRAM insufficiency (Option B): VRAM (video memory) issues would typically cause display-related errors, not memory configuration issues.
* RAID cache failure (Option C): RAID cache issues would lead to storage errors but not prevent the system from configuring memory.
* BIOS update (Option D): While BIOS issues can cause boot failures, the error message suggests a memory-specific issue.

ある企業がすべてのユーザーにソフトウェアを展開したいと考えていますが、ある時点でそのソフトウェアを使用する男性はごくわずかです。次のライセンス モデルのうち、会社にとって最適なライセンス モデルはどれですか?
- A. コアあたり
- B. サイトごと
- C. 同時ユーザーあたり
- D. インスタンスごと
正解：C
解説：
Explanation
Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines. References:

Hosting data in different regional locations but not moving it for long periods of time describes:
- A. a cold site.
- B. off-site storage.
- C. on-site retention.
- D. data at rest.
正解：D
解説：
Data at rest refers to data that is stored in a persistent state on any device or media, such as hard drives, tapes, or cloud storage. Data at rest does not move for long periods of time unless it is accessed or modified by authorized users or applications. A cold site (A) is a backup location that has minimal or no equipment and resources to resume business operations in case of a disaster. On-site retention is a policy of keeping backup data on premises for a certain period of time before transferring it to an off-site location. Off-site storage (D) is a method of storing backup data in a remote location that is physically or logically separated from the primary site.

管理者は、会社サーバー上にある DATA という共有フォルダーに対する変更権限をアンに与えました。他のユーザーは、このフォルダー内のファイルへの読み取りアクセスが必要です。現在の構成は次のとおりです。
管理者は、アンがネットワークを使用して DATA フォルダに何も書き込むことができないと判断しました。アンの権限を正しく設定し、必要な最小限の権限のみを公開するためのベスト プラクティスは次のうちどれですか?
- A. オプション C
- B. オプション D
- C. オプション A
- D. オプション B
正解：B
解説：
Explanation
Option D is the best practice to set up Ann's permissions correctly, exposing only the minimum rights required. Option D shows that the share permissions on the DATA folder grant Ann Change access, which allows her to read, write, and delete files in the shared folder. The file permissions grant Ann Modify access, which allows her to read, write, execute, and delete files in the folder. This combination of permissions gives Ann the ability to write anything to the DATA folder using the network, as well as to modify and delete existing files. This meets the requirement of giving Ann modify permissions to the shared folder.
質問 # 230
An administrator is working on improving the security of a new domain controller. A report indicates several open ports on the server. Which of the following ports should the administrator disable?
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
The port that should be disabled on the firewall is port 3389. Port 3389 is used by Remote Desktop Protocol (RDP), which is a protocol that allows remote access and control of a Windows system through a graphical user interface. RDP can pose a security risk if it is not properly configured or secured, as it can expose the system to unauthorized or malicious access from external sources. Therefore, port 3389 should be disabled on the firewall unless it is needed for legitimate purposes.
質問 # 231
A systems administrator has several different types of hard drives. The administrator is setting up a MAS that will allow end users to see all the drives within the NAS. Which of the following storage types should the administrator use?
- A. Just a bunch of disks
- B. RAID array
- C. Serial Attached SCSI
- D. Solid-state drive
正解：A
解説：
JBOD (Just a Bunch Of Disks) is a storage configuration that combines different types and sizes of hard drives into one logical unit without any RAID level or redundancy. It allows users to see all the drives within the unit as one large storage space. JBOD can utilize all the available capacity of the drives but does not provide any performance or fault tolerance benefits. Verified References: [JBOD], [RAID]

質問 # 233
技術者は、サーバーのセカンダリ NIC を別のネットワークに接続しています。技術者はケーブルをスイッチに接続しますが、NIC にリンク ライトが表示されません。技術者は、ネットワークまたは物理接続に問題がないことを確認します。技術者が次に実行する必要があるのは次のうちどれですか?
- A. サーバーを再起動します
- B. サーバーのポートを有効にします
- C. サーバーでネットワークを構成する
- D. DHCP 構成を確認します。
正解：B
解説：
The next thing that the technician should perform is to enable the port on the server. A port is a logical endpoint that identifies a specific service or application on a network device. A port can be enabled or disabled depending on whether the service or application is running or not. If a port is disabled on a server, it means that the server cannot send or receive any network traffic on that port, which can prevent communication with other devices or services that use that port. In this case, if port 389 is disabled on the server, it means that the server cannot use LDAP to access or modify directory services over a network. To resolve this issue, the technician should enable port 389 on the server using commands such as netsh or iptables.
質問 # 234
サーバー管理者は、アプリケーション サーバーでバックアップを実行する必要がある頻度を決定するためにビジネス要件を収集しています。管理者が確立しようとしているのは次のうちどれですか?
- A. RPO
- B. MTBF
- C. RFC
- D. MTTR
正解：A
解説：
The administrator is attempting to establish the recovery point objective (RPO) by determining how frequently backups need to be performed on an application server. RPO is a metric that defines how much data can be lost or how far back in time a recovery can go in case of a disaster or disruption, based on the business requirements and impact analysis of an organization or system. RPO is measured by the time interval between backups or snapshots of data, such as hourly, daily, weekly, etc., depending on how critical or sensitive the data is and how often it changes or updates.

技術者は、実稼働環境からサーバーを廃止しています。技術者はサーバーをラックから取り外しましたが、システムを廃止するのではなく、ラボ サーバーとして再利用することにしました。システムドライブをリサイクルして再利用するための最も適切な次のステップは、次のうちどれですか?
- A. ドライブをワイプします。
- B. OS を再インストールします。
- C. ドライブを消磁します。
- D. IP スキーマを更新します。
正解：A
解説：
Wiping the drives is the most appropriate step to recycle and reuse the system drives. Wiping the drives means erasing all the data on the drives and overwriting them with random or meaningless data. This can help prevent data leakage, comply with regulations, and prepare the drives for a new installation or configuration. Wiping the drives is different from deleting or formatting the drives, which only remove the references to the data but not the data itself.

質問 # 239
A server administrator is currently working on an incident. Which of the following steps should the administrator perform before resolving the issue?
- A. Make the changes to the system.
- B. Inform the impacted users.
- C. Determine the probable causes.
- D. Identify changes to the server.
正解：C
解説：
The step that the server administrator should perform before resolving the issue is to determine the probable causes. This step is part of the troubleshooting process that follows a logical and systematic approach to identify and solve problems with servers and applications. The troubleshooting process consists of several steps, such as:
Identify the problem: Gather information from various sources, such as users, logs, or alerts, to understand the symptoms and scope of the problem.
Establish a theory of probable cause: Analyze the information and formulate one or more possible causes of the problem based on evidence or experience.
Test the theory to determine cause: Perform tests or experiments to verify or eliminate each possible cause until the root cause is found.
Establish a plan of action to resolve the problem and implement the solution: Design and execute a plan to fix the problem using appropriate tools and techniques.
Verify full system functionality and implement preventive measures: Confirm that the problem is resolved and that no other issues arise as a result of the solution. Implement preventive measures to avoid recurrence of the problem or improve performance.
Document findings, actions, and outcomes: Record the details of the problem, its cause, its solution, and its outcome for future reference or knowledge sharing. References: [CompTIA Server+ Certification Exam Objectives], Domain 6.0: Troubleshooting, Objective 6.1: Given a scenario involving server hardware issues (e.g., power supply failure), troubleshoot using appropriate tools.

質問 # 242
An administrator discovers a Bash script file has the following permissions set in octal notation;
777
Which of the following is the MOST appropriate command to ensure only the root user can modify and execute the script?
- A. chmod g-rwx
- B. chmod u+wx
- C. chmod go-rw>:
- D. chmod u=rwx
正解：C
解説：
chmod is a command-line tool that changes the permissions of files and directories in Linux and Unix systems. chmod go-rwx means to remove read, write, and execute permissions for group and other users from a file or directory. This can ensure only the root user can modify and execute the script, since root user has full access to all files and directories regardless of their permissions. References: https://linux.die.net/man/1/chmod
質問 # 243
技術者は Linux サーバーで作業しています。顧客から、ホーム ディレクトリ内のファイルが見つからないと報告がありました。 /etc/f stack ファイルには次のエントリがあります。
nfsserver:/home /home nfs のデフォルト 0 0
ただし、df -h /home コマンドは次の情報を返します。
/dev/sda2 10G 1G 9G 10% /home
技術者が問題を解決するために最初に試みるべきことは次のうちどれですか?
- A. umount nfsserver:/home
- B. mkdir /home
- C. rmdir nfsserver:/home/dev/sda2
- D. /home をマウントします
正解：A
解説：
The /etc/fstab file contains the information about the file systems that are mounted automatically at boot time or on demand. The entry nfsserver:/home /home nfs defaults 0 0 indicates that the /home directory on the local server is mounted from the /home directory on a remote server called nfsserver using the NFS protocol. However, the df -h /home command shows that the /home directory is actually mounted from a local partition /dev/sda2, which may not contain the user's files. This means that the NFS mount failed or was overridden by another mount. To resolve the issue, the technician should attempt to unmount the local partition using umount nfsserver:/home, which will detach the /home directory from /dev/sda2. Then, the technician should try to mount the NFS share again using mount /home, which will attach the /home directory to nfsserver:/home according to the /etc/fstab entry12. Creating a new directory (A) or removing an existing one would not help, as they would not affect the mount point. Mounting /home (D) without unmounting it first would not work, as it would result in an error that the mount point is busy3.
