A benefit of synchronous remote replication is that it ensures the source and replica always have identical data. This type of replication immediately writes changes to both the source and the replica, maintaining data consistency and integrity between the two locations at all times.

VxBlock provides a converged infrastructure solution, integrating compute, network, and storage resources into a single system to simplify data center management.

Secure multitenancy is designed to provide a level of isolation and security between different tenants sharing the same physical infrastructure in cloud computing. The primary benefit is that it reduces unauthorized access to resources, ensuring that each tenant's data and applications are protected from other tenants. While it cannot eliminate all risks, it significantly mitigates the chances of unauthorized access.

Fault tolerance is the ability of a system to continue operating properly in the event of the failure of some of its components. Two key requirements for fault tolerance are Fault Isolation, which involves identifying and isolating failed components to prevent them from affecting the rest of the system, and Eliminating Single Points of Failure (SPOFs), which ensures there are no single components whose failure would cause the entire system to fail. Therefore, the correct answer is Fault Isolation and Eliminate SPOF.

Agile is the standard being utilized because it is known for its iterative and incremental approach to software development. This method involves gradually adding features and frequently releasing updates in cycles, which aligns with the description given in the question.
