Practice Exam 7 Flashcards
A developer has developed a 3-tier web application that will be deployed directly on Amazon EC2. The developer is considering deploying the application to more than one Availability Zone. What advantages does this deployment approach offer?
(choose 3)
Higher performance and higher latency since Availability Zones are spread out
Increase in responsiveness when load balancing is used
Improves the availability of the application
Reduced operational costs because you’re spreading data transfer costs between Availability Zones
Enhances resiliency, allowing the application to recover from failure due to load
-Increase in responsiveness when load balancing is used
If 1 Availability Zone is constrained, the instances in another Availability Zone can handle the traffic.
-Improves the availability of the application
If 1 Availability Zone is completely destroyed, you will still have a completely functional web application running in a different Availability Zone.
-Enhances resiliency, allowing the application to recover from failure due to load
Resilient/fault-tolerant systems recover quickly and minimize application downtime. If 1 instance fails, another instance in a different Availability Zone can handle the request.

With AWS services, you can use as many resources as you need, as well as use them when you need them. Which of the following terms can be applied to this concept?
Dedicated resources
Fixed resources
Temporary resources
Disposable resources
Temporary resources
Disposable resources
Working in a traditional infrastructure environment means you have to deal with fixed resources, which is comparatively costly and labor-intensive. By contrast, AWS services are much more convenient; the services provide the ability to use as many resources as you need and dispose of them when you no longer need them. That’s why such resources are both temporary and disposable.
