問題 #80
Which criterion is used to assess off-site storage solutions?

答案：B

解題說明：
Security is a primary criterion used to assess off-site storage solutions because stored backups must be protected against unauthorized access, theft, tampering, and data leakage. In Information Technology disaster recovery and business continuity planning, off-site backups often contain sensitive business records, customer information, and proprietary data. Therefore, evaluation typically includes physical security controls such as guarded facilities, access logs, surveillance, and secure transport, as well as logical security controls such as encryption, key management, and strong authentication. While redundancy and capacity can matter, security is often treated as a non-negotiable requirement because a backup that is exposed or altered can create major legal, financial, and operational risks. Device media refers to the type of storage, such as tape or disk, but it is usually considered a design choice rather than the main assessment criterion. Security also supports compliance requirements and helps ensure data integrity, so restored systems can be trusted. Therefore, the correct criterion for assessing off-site storage solutions is security.


問題 #81
Why is business continuity planning essential?

答案：C


問題 #82
Which of the following is required for communication over the Internet?

答案：E

解題說明：
Communication over the Internet relies on packet-switched networks. Here's why:
1.Packet Switching:
oThe Internet uses a packet-switching approach to transmit data.
oIn this method, data is divided into smaller packets before transmission.
oEach packet contains a portion of the original data along with addressing information.
oThese packets are then sent independently across the network.
oAt the destination, the packets are reassembled to reconstruct the original data.
2.Advantages of Packet Switching:
oEfficiency: Packet switching allows multiple users to share the same network resources efficiently.
oRobustness: If a link or node fails, packets can find alternative routes to reach their destination.
oScalability: The network can handle varying traffic loads without significant reconfiguration.
3.Other Options:
oAn IP Alias: An IP alias is an additional IP address associated with a network interface. It is not a requirement for communication over the Internet.
oA LAN (Local Area Network): A LAN is a local network within a limited geographical area. While LANs are essential for local communication, they are not directly required for Internet communication.
oA circuit-switched network: Circuit-switched networks establish dedicated connections between sender and receiver. The Internet does not use this approach.
oAn analog signal: Analog signals were used in older communication systems (e.g., telephone lines), but the Internet primarily relies on digital signals.
