EMC Proven Professional – Cloud Architect — Question 3

An organization is using a public cloud provider for IaaS instances. The organization has developed and deployed a web application within these instances. The organization wishes to formalize an SLA that specifies that the public cloud provider will:
Respond to infrastructure outages within 4 hours
✑ Offer multiple availability zones
✑ Ensure application up-time of 99.9%
✑ Provide monthly billing reports
Why would the public cloud provider disagree with these terms?

Answer options

• A. IaaS instances are virtual and therefore do not require a monthly bill.
• B. Availability zones must span multiple cloud providers.
• C. Application up-time is not the responsibility of other cloud provider.
• D. Infrastructure outages are not the responsibility of the cloud provider.

Correct answer: C

Explanation

The correct answer is C because the application uptime is typically the responsibility of the organization deploying the application, not the cloud provider. Options A and B are incorrect as they misrepresent billing practices and the nature of availability zones, respectively. Option D is also incorrect, as the cloud provider is generally responsible for infrastructure outages, but not for application-level issues.
