D. Data center ownership
Click to view Answer & Explanation
**Correct Answer:** A **Explanation:** * **Why A is correct:** Cloud agility enables organizations to provision resources quickly, experiment, and release applications faster than purchasing and configuring physical infrastructure. * **Why B is incorrect:** Dedicated host isolation is a specific infrastructure option and does not represent the primary benefit of quickly obtaining cloud resources. * **Why C is incorrect:** Manual capacity planning can delay deployments and is one of the limitations the cloud helps reduce. * **Why D is incorrect:** AWS customers use AWS infrastructure without owning or operating AWS data centers.Question 4
A financial services company wants its customer-facing application to continue operating if one data center experiences a hardware or power failure. Which AWS Global Infrastructure design should the company use?
A. Deploy resources across multiple Availability Zones in an AWS Region
B. Deploy all resources in a single Availability Zone
C. Use AWS CloudTrail in one Availability Zone
D. Use AWS Direct Connect with one network circuit
Click to view Answer & Explanation
**Correct Answer:** A **Explanation:** * **Why A is correct:** Availability Zones are separate locations within an AWS Region and are designed to be isolated from failures in other Availability Zones. Deploying across multiple Availability Zones can improve application availability. * **Why B is incorrect:** A single Availability Zone can be a single point of failure for the application. * **Why C is incorrect:** AWS CloudTrail provides activity logging and does not by itself provide application redundancy. * **Why D is incorrect:** A single AWS Direct Connect circuit can itself become a point of failure and does not distribute application resources across Availability Zones.Question 5
