                                          Therefore, the correct answer is B. IT allows businesses to have a global reach.


                                          NEW QUESTION # 78
                                          What is an important strategy of business continuity planning?

                                          Answer: A

                                          Explanation:
                                          Data mirroring is an important business continuity strategy because it maintains a synchronized copy of data on a separate storage system or site. In Information Technology, mirroring supports rapid recovery by ensuring that if the primary data store fails, an up-to-date replica is available to restore operations. Mirroring may be implemented through storage replication, database replication, or real-time backup technologies, and it is often used for high-availability systems that require minimal data loss. This approach directly supports business continuity goals by reducing recovery time and limiting the recovery point, meaning less data is lost between the failure and the restored system. User authentication and data encryption are critical security controls, but they do not by themselves ensure operational continuity after outages or disasters. Service variety is not a standard continuity strategy term in most IT curricula. Business continuity focuses on redundancy, replication, failover, and recovery processes. Since mirroring creates a continuously updated duplicate of critical data, it is a core strategy used to maintain availability and speed restoration. Therefore, the correct answer is data mirroring.


                                          NEW QUESTION # 79
                                          Which aspect of the CIA Triad requires that data are correct?

                                          Answer: D

                                          Explanation:
                                          1.Integrity: This principle focuses on maintaining the accuracy and trustworthiness of data. It ensures that data remains unaltered and free from corruption. Key points related to integrity:
                                          oData Accuracy: Integrity ensures that data reflects the true state of information. Any unauthorized changes or alterations are detected and prevented.
                                          oHash Functions: Hash functions are commonly used to verify data integrity. These functions generate a fixed-size hash value (checksum) based on the original data. If any part of the data changes, the hash value will also change, indicating potential tampering.
                                          oDigital Signatures: Digital signatures provide a way to verify the integrity of electronic documents. They use asymmetric encryption to sign data, ensuring that it has not been altered since the signature was applied.
                                          oData Validation: Implementing input validation and proper access controls helps maintain data integrity by preventing unauthorized modifications.
                                          2.Confidentiality and Availability:
                                          oConfidentiality: This principle ensures that only authorized users can access sensitive data. It focuses on keeping information private and restricting access.
                                          oAvailability: Availability ensures that authorized users can access data when needed. It prevents data from being unavailable due to system failures, attacks, or other disruptions.
                                          3.Balancing the Triad:
                                          oWhile all three principles are essential, they can sometimes conflict with each other. For example:
                                          Enhancing confidentiality (e.g., strong encryption) may impact availability (e.g., longer decryption times).
                                          Rigorous integrity checks can affect system performance.
                                          oOrganizations must strike a balance based on their specific security requirements.

                                          NEW QUESTION # 80
                                          What can applications use to interact with a database?

                                          Answer: D

                                          Explanation:
                                          SQL is the standard language for communicating with relational databases. Applications use SQL to:
                                          *Retrieve data: SELECT queries are used to fetch specific data from database tables.
                                          *Modify data: INSERT, UPDATE, and DELETE statements allow applications to add, change, or remove data in the database.
                                          *Manage database structure: CREATE, ALTER, and DROP statements let applications create tables, modify their structure, or delete them entirely.


                                          NEW QUESTION # 81
                                          What does a router do?

                                          Answer: B

                                          Explanation:
                                          A router manages network traffic by using a routing table to determine where data packets should be sent. In Information Technology networking, a router connects different networks, such as a home local network and the internet, and forwards packets based on destination IP addresses. The routing table contains information about known networks and the best path to reach them. This allows the router to direct traffic efficiently between networks and to serve as a gateway for devices on a local area network. Option A describes a server, which provides services like hosting websites or applications. Option C describes a repeater, which boosts or regenerates signals to extend cable distance. Option D describes a modem, which modulates and demodulates signals to convert between analog and digital forms for transmission over certain media. While modern home routers may also include switch and wireless access point features, the core routing function is traffic management using routing information. Therefore, the correct answer is the option describing maintaining a table and managing traffic, which is option B.
