Explanation:
A software baseline is the cut-off point in the design and development of a system beyond which additional requirements or modifications to the design do not or cannot occur without undergoing formal strict procedures for approval based on a business cost-benefit analysis. Failure to adequately manage the requirements of a system through baselining can result in a number of risks. Foremost among these risks is scope creep, the process through which requirements change during development. Choices B, C and D may not always result, but choice A is inevitable.

A database conflict occurs when the same data is modified at two separate servers, such as a customer database and a remote call center database, and the changes are not consistent with each other. For example, if a customer updates their phone number at the customer database, and a call center agent updates the same customer's address at the remote call center database, there is a conflict between the two updates. Database conflicts can cause data inconsistency, corruption, or loss if they are not detected and resolved properly.
Two-way replication is a process of synchronizing data between two databases, so that any changes made in one database are reflected in the other database, and vice versa. Two-way replication can improve data availability, performance, and scalability, but it also increases the risk of database conflicts. Therefore, when assessing a proposed project for the two-way replication of a customer database with a remote call center, the IS auditor should ensure that database conflicts are managed during replication. This means that the project should have a clear and effective strategy for:
* Preventing or minimizing database conflicts by using techniques such as locking, timestamping, or partitioning.
* Detecting or identifying database conflicts by using tools such as triggers, logs, or alerts.
* Resolving or handling database conflicts by using methods such as priority-based, rule-based, or user-based resolution.
The other possible options are:
* B. end users are trained in the replication process: This is not a relevant or important factor for the IS auditor to ensure when assessing a proposed project for the two-way replication of a customer database with a remote call center. End users are not directly involved in the replication process, and they do not need to have detailed knowledge or skills about how replication works. The replication process should be transparent and seamless to the end users, and they should only interact with the data through their applications or interfaces.
* C. the source database is backed up on both sites: This is not a sufficient or necessary factor for the IS auditor to ensure when assessing a proposed project for the two-way replication of a customer database with a remote call center. Backing up the source database on both sites can provide some level of data
* protection and recovery, but it does not address the issue of database conflicts that can occur during replication. Moreover, backing up the source database on both sites may not be feasible or efficient, as it may consume more storage space and network bandwidth, and introduce more complexity and overhead to the replication process.
* D. user rights are identical on both databases: This is not a critical or relevant factor for the IS auditor to ensure when assessing a proposed project for the two-way replication of a customer database with a remote call center. User rights are the permissions or privileges that users have to access or modify data in a database. User rights do not directly affect the occurrence or resolution of database conflicts during replication. User rights may vary depending on the role or function of the users in different databases, and they should be defined and enforced according to the security policies and requirements of each database.

Open hubs represent a significant control weakness because of the potential to access a network connection easily. An intelligent hub would allow the deactivation of a single port while leaving the remaining ports active. Additionally, physical security would also provide reasonable protection over hubs with active ports.
