VMware vSphere 6 Advanced Design (VCAP6-DCV Design) — Question 13

A company has requested a new vSphere 6.5 design that will allow it to finally break the 80 virtualization barrier by virtualizing its resource-intensive application.
✑ The application is highly available by design and includes application-aware clustering software capable of operating as a fully distributed system.
✑ The company's Application Version 2.0 consists of 386 small applications and middleware with non-persistent storage and 24 database virtual machines at each data center.
✑ When coupled with a proper load balancing solution, this application can continue operating even with the loss of an entire data center, but the small applications and middleware tiers within a data center must exist within the same broadcast domain.
✑ The database tier is tightly controlled with a firewall policy that only allows middleware tier access, and is replicated to other sites using a dedicated circuit.
Which two application requirements apply to this scenario? (Choose two.)

Answer options

• A. The application will require the configuration of an IGMP stub and helper.
• B. Shared storage is required by the application clustering software.
• C. The application will require one large subnet.
• D. The application will require a method of balancing and recovering sessions between sites.

Correct answer: B, D

Explanation

The correct answers are B and D because the application clustering software requires shared storage to function properly and maintain high availability, while a method for balancing and recovering sessions between sites is essential for continuity during data center outages. Options A and C are incorrect as they do not align with the specific requirements outlined for the application's operation and architecture.
