Exam Name: Storage Networking Design Specialist Exam for Data Center Architects
An organization purchased a NAS storage infrastructure to service all its applications for three years. Various cost components for this deployment are as follows:
• Initial cost includes the purchase cost of $2,000 and an installation charge of $400.
• Organization needs to pay $200 per year for maintenance and $100 per year as license fees.
• From Year 2, the organization must pay $1,000 per year for OS upgrades.
At the end of the three years, the organization needs to pay a recycling fee of $50 to dispose of the NAS device that will no longer be needed. What is the total cost of ownership (TCO) each year to implement this technology infrastructure?
A company is comparing two technology options for their IT environment. Option 1 is to retain the existing legacy environment, and Option 2 will require the replacement of the current solution with a new solution.
• Operation costs including maintenance of the current infrastructure = $300,000 per year
• Investment in additional storage requirements = $100,000 per year
• Initial cost of the new solution = $1,000,000
• Operation costs with the new infrastructure = $150,000 per year
• Investment in additional storage = $50,000 per year
The company’s write-off cost for the current solution is $50,000. As a business analyst, what would you recommend to the company based on the TCO?
A. Option 1 is feasible if the project lifespan is less than 5 years
B. Option 1 is feasible if the project lifespan is more than 6 years
C. Option 2 is feasible if the project lifespan is less than 5 years
D. Options 1 and 2 are feasible if the project lifespan is 5 years
A director contains eight port cards with four ports per card. If two of the director’s port cards are unavailable for five minutes, what is the path minute of SAN performance degradation?
A redundant switch contains eight-port cards with four ports per card. If one of the port cards is unavailable for eight minutes before it is hot swapped, what is the resultant path minute of SAN performance degradation?

What does a non-functional requirement (NFR) address?
A. System constraints and qualities
B. System tasks and services
