Rebooting the system in safe mode will limit the number of programs and processes running, allowing the antivirus system to more effectively identify and remove the malware. Rescanning the system will allow the antivirus system to identify and remove the malware while preserving the user's files.

質問 # 83
ユーザーはよく使用される Web ページにアクセスしようとしましたが、予期しない Web サイトにリダイレクトされました。Web ブラウザのキャッシュをクリアしても問題は解決しません。問題を解決するために技術者が NEXT を調査する必要があるのは、次のうちどれですか?

• A. ウイルス対策定義を更新します。
• B. ルーティング テーブルを確認します。
• C. ファイアウォール ACL を有効にします。
• D. localhost ファイルのエントリを調べます。

正解：D

解説：
Explanation
A possible cause of the user being redirected to unexpected websites is that the localhost file entries have been modified by malware or hackers to point to malicious or unwanted websites. The localhost file is a text file that maps hostnames to IP addresses and can override DNS settings. By examining the localhost file entries, a technician can identify and remove any suspicious or unauthorized entries that may cause the redirection issue.
Enabling firewall ACLs may not resolve the issue if the firewall rules do not block the malicious or unwanted websites. Verifying the routing tables may not resolve the issue if the routing configuration is correct and does not affect the web traffic. Updating the antivirus definitions may help prevent future infections but may not remove the existing malware or changes to the localhost file.

In addition, users should be trained to avoid clicking on links or downloading attachments from unknown sources1. By providing user training, the management team can reduce the risk of users opening spam messages and potentially infecting the network systems1.

質問 # 87
従業員がラップトップ PC の問題についてヘルプ デスクに電話します。Windows の更新後、ユーザーはローカルに接続された特定のデバイスを使用できなくなり、再起動しても問題は解決されませんでした。問題を解決するために技術者が実行する必要があるのは、次のうちどれですか?

• A. Windows Update サービスを無効にします。
• B. 非表示の更新を復元します。
• C. アップデートを確認します。
• D. 更新をロールバックします。

正解：D

解説：
The technician should perform a rollback of the Windows update that caused the issue with the locally attached devices. A rollback is a process of uninstalling an update and restoring the previous version of the system. This can help to fix any compatibility or performance issues caused by the update1. To rollback an update, the technician can use the Settings app, the Control Panel, or the System Restore feature. The technician should also check for any device driver updates that might be needed after rolling back the update.
Disabling the Windows Update service is not a good practice, as it can prevent the system from receiving important security and feature updates. Checking for updates might not fix the issue, as the update that caused the issue might still be installed. Restoring hidden updates is not relevant, as it only applies to updates that have been hidden by the user to prevent them from being installed2.

質問 # 89
ある大規模な組織は、マルチユーザー環境向けにベンダーのサポートを受けて独自のソフトウェアを研究しています。次の EULA タイプのうちどれを選択する必要がありますか?

• A. 永久
• B. 法人
• C. 個人的なもの
• D. オープンソース

正解：B

解説：
Explanation
A corporate EULA is a type of end-user license agreement that is designed for a large organization that needs to use proprietary software with vendor support for a multiuser environment. A corporate EULA typically grants the organization a volume license that allows it to install and use the software on multiple devices or servers, and to distribute the software to its employees or affiliates. A corporate EULA also usually provides the organization with technical support, maintenance, updates, and warranty from the software vendor, as well as some customization options and discounts. A corporate EULA may also include terms and conditions that specify the rights and obligations of both parties, such as confidentiality, liability, indemnification, termination, and dispute resolution12.
A corporate EULA is a better option than the other choices because:
A perpetual EULA (B) is a type of end-user license agreement that grants the user a permanent and irrevocable license to use the software, without any time limit or expiration date. However, a perpetual EULA does not necessarily include vendor support, updates, or warranty, and it may not allow the user to install the software on multiple devices or servers, or to distribute the software to other users. A perpetual EULA may also be more expensive than a corporate EULA, as it requires a one-time payment upfront, rather than a recurring subscription fee34.
An open-source EULA is a type of end-user license agreement that grants the user a license to use, modify, and redistribute the software, which is publicly available and free of charge. However, an open-source EULA does not provide any vendor support, maintenance, updates, or warranty, and it may impose some restrictions or obligations on the user, such as disclosing the source code, attributing the original author, or using a compatible license for derivative works. An open-source EULA may not be suitable for a large organization that needs proprietary software with vendor support for a multiuser environment56.
A personal EULA (D) is a type of end-user license agreement that grants the user a license to use the software for personal, non-commercial purposes only. A personal EULA may limit the number of devices or servers that the user can install the software on, and prohibit the user from distributing, copying, or reselling the software to other users. A personal EULA may also provide limited or no vendor support, maintenance, updates, or warranty, and it may have a fixed or renewable term. A personal EULA may not meet the needs of a large organization that needs proprietary software with vendor support for a multiuser environment7 .

• C. システム パッチにより、ウイルス対策保護とホスト ファイアウォールが無効になりました。
• D. システム アップデートには、最新のマルウェア対策定義が含まれていませんでした。

正解：B

解説：
The best explanation for why the system still has malware after performing a System Restore is that the malware was installed before the system restore point was created. A system restore point is a snapshot of the system settings and configuration at a certain point in time. A System Restore is a feature that allows users to restore their system to a previous state in case of problems or errors. However, a System Restore does not affect personal files or folders, and it may not remove malware that was already present on the system before the restore point was created. A system patch disabling the antivirus protection and host firewall may increase the risk of malware infection, but it does not explain why the malware persists after a System Restore. The system updates not including the latest anti-malware definitions may reduce the effectiveness of malware detection and removal, but it does not explain why the malware persists after a System Restore. The system restore process being compromised by the malware may prevent a successful System Restore, but it does not explain why the malware persists after a System Restore.

次のプロトコルのうち、ネットワーク間の高速ローミングをサポートしているものはどれですか?

• A. WPA2
• B. PEAP
• C. WPA
• D. LEAP
• E. WEP

正解：C

解説：
WPA2 is the only protocol among the options that supports fast roaming between networks. Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), enables a client device to roam quickly in environments implementing WPA2 Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another1. WEP, WPA, LEAP, and PEAP do not support fast roaming and require the client device to perform the full authentication process every time it roams, which can cause delays and interruptions in the network service.

• A. ネットワーク コンテンツ フィルタリングを追加します。
• B. ポートフォワーディングを設定します。
• C. SSIDブロードキャストを無効にします。
• D. デフォルトの認証情報を変更します。

正解：D

解説：
One of the most effective ways to defend against malicious actors targeting home routers for DDoS attacks is to change the default credentials of the router. The default credentials are often well-known or easily guessed by attackers, who can then access and compromise the router settings and firmware. By changing the default credentials to strong and unique ones, a technician can prevent unauthorized access and configuration changes to the router. Adding network content filtering may help block some malicious or unwanted websites but may not prevent attackers from exploiting router vulnerabilities or backdoors. Disabling the SSID broadcast may help reduce the visibility of the wireless network but may not prevent attackers from scanning or detecting it. Configuring port forwarding may help direct incoming traffic to specific devices or services but may not prevent attackers from sending malicious packets or requests to the router.
