1.You need to run a job on an EC2 instance. Application deployed reads the data from S3 storage, perform the compute related operations, and then saves the results in S3 storage again. The application is designed in such a way that it could handle failures gracefully. There is no rush to complete the job. Which one of the instance types can be proved to be most cost-effective?
D.A fleet of EC2 instances running behind an ELB
Rationale of answers
Options A and B are incorrect:- On-demand EC2 instances should be used for the application that needs permanent and long-term data storage. Whereas, Reserved instances are used when your application is stable and does not require too many frequent changes/degrade/upgrade in resource capacities such as RAM or CPU. Hence, Option A and B both are incorrect answers.
Option C is correct:- Spot instances should be used when your priority is cost saving and your application is acceptable to be interrupted. Hence, this is the correct answer.
Option D is incorrect:- Fleet of EC2 instances should be used only when your application needs to be highly available, scalable, and durable. Hence, option D is the incorrect answer.

2.You have been asked to configure a Route 53 routing policy for a Web application where Route 53 can respond to DNS queries with up to eight healthy records selected at random. Which one of following Route 53 routing policies should you use?
A.Weighted routing policy
B.Multivalue answer routing policy
C.Latency-based routing policy
D.Geolocation-based routing policy
Rationale of answers
Option A is incorrect:- Weighted routing policy routes traffic to multiple resources in proportions specified by you. Hence, this is an incorrect answer.
Answer B is correct:- Multivalue answer routing policy allows Route 53 to respond to DNS queries with up to eight healthy records selected at random. Hence this is the correct answer.
Option C is incorrect:- You should use the latency routing policy when you have resources in multiple AWS Regions and you want to route traffic to the region that provides the minimum latency. Hence this is an incorrect answer.
Option D is incorrect:- Geolocation routing policy routes traffic based on the location of your users.
