VMware vSphere 8.x Advanced Design (VCAP-DCV Design) — Question 11

An architect is responsible for designing a vSphere-based solution for a customer. The customer has the following requirements:
The solution must provide redundancy and load balancing for storage traffic
The solution must tolerate at least one failure
There must be no single point of failure in the solution
Which three considerations regarding physical host design should the architect analyze when making storage related design decisions? (Choose three.)

Answer options

• A. Configure the fixed multi-pathing policy on the ESXi hosts
• B. Use four single port storage host bus adapters (HBAs) in each ESXi host
• C. Use an active-active array for Fibre Channel storage-based VMFS datastores
• D. Configure a minimum of two paths to every LUN or datastore
• E. Configure a minimum of four paths to every LUN or datastore
• F. Use one quad-port storage host bus adapter (HBA) in each ESXi host

Correct answer: B, C, E

Explanation

Option B is correct because using four single-port HBAs increases redundancy and load balancing. Option C is also correct as active-active arrays enhance performance and fault tolerance for storage. Option E is correct since having a minimum of four paths to each LUN or datastore provides additional redundancy; however, options A, D, and F do not meet the requirements as effectively for redundancy and load balancing.
