Secondly they claim that their data store is not frequently accessed. What is the best and cost efficient solution that should be considered? Please select : A. Amazon Storage Gateway B. Amazon Glacier C. Amazon EBS D. Amazon S3 Your answer is incorrect. Answer: B – Since the data is not required to be accessed frequently, the data can be stored on Amazon glacier for cheaper storage. Remember that the recovery time for getting data from Glacier is from 3-5 hours. All other options are not correct and expensive compared to Amazon Glacier service.
Question 2 Not answered For more information on Glacier please visit the below URL: The correct answer is: Amazon Glacier A company does not want to manage their databases. Which of the following services are fully managed databases provided by AWS? Please select : A. AWS RDS B. DynamoDB C. Oracle RDS D. Elastic Map Reduce Your answer is incorrect. Answer: - B DynamoDB is a fully managed NoSQL offering provided by AWS. It is now available in most regions for users to consume. AWS RDS database is not fully managed database, it is partially managed. For RDS, we still need to specify the server capacity , security group etc. This is the point most of them are confused, because they assume that RDS is the fully managed database. Even though the question doesn't ask about the type of database (NOSQL), the correct option is DynamoDB.
Question 3 Not answered For the fully managed option it is Aurora and DynamoDB. So, the correct option in this question is DynamoDB. The link provides the full details on the product 1. 2. The correct answer is: DynamoDB Which of the following requires a custom CloudWatch metric to monitor? Please select : A. Memory Utilization of an EC2 instance B. CPU Utilization of an EC2 instance C. Disk Reads activity of an EC2 instance D. Networks packets out of an EC2 instance Your answer is incorrect. Answer – A Memory Utilization is a metric not offered directly by Cloudwatch. So when you view the Cloudwatch metrics for your EC2 instance, you can see CPU Utilization and Disk Read Operations metrics. You can also see Network statistics for Data transfer, but you will not be able to see Memory Utilization. This will be a custom Cloudwatch metric.
