NEW QUESTION # 195
One of the AWS account owners faced a major challenge in June as his account was hacked and the hacker deleted all the data from his AWS account. This resulted in a major blow to the business.
Which of the below mentioned steps would not have helped in preventing this action?
- A. Setup an MFA for each user as well as for the root account user.
- B. Do not share the AWS access and secret access keys with others as well do not store it inside programs, instead use IAM roles.
- C. Take a backup of the critical data to offsite / on premise.
- D. Create an AMI and a snapshot of the data at regular intervals as well as keep a copy to separate regions.
Answer: D
Explanation:
Explanation
AWS security follows the shared security model where the user is as much responsible as Amazon. If the user wants to have secure access to AWS while hosting applications on EC2, the first security rule to follow is to enable MFA for all users. This will add an added security layer. In the second step, the user should never give his access or secret access keys to anyone as well as store inside programs. The better solution is to use IAM roles. For critical data of the organization, the user should keep an offsite/ in premise backup which will help to recover critical data in case of security breach. It is recommended to have AWS AMIs and snapshots as well as keep them at other regions so that they will help in the DR scenario. However, in case of a data security breach of the account they may not be very helpful as hacker can delete that.
Therefore, creating an AMI and a snapshot of the data at regular intervals as well as keep a copy to separate regions, would not have helped in preventing this action.
NEW QUESTION # 196
A company had a tight deadline to migrate its on-premises environment to AWS. It moved over Microsoft SQL Servers and Microsoft Windows Servers using the virtual machine import/export service and rebuild other applications native to the cloud. The team created both Amazon EC2 databases and used Amazon RDS.
Each team in the company was responsible for migrating their applications, and they have created individual accounts for isolation of resources. The company did not have much time to consider costs, but now it would like suggestions on reducing its AWS spend.
Which steps should a Solutions Architect take to reduce costs?
- A. Create a budget and monitor for costs exceeding the budget. Create Amazon EC2 Auto Scaling groups for applications that experience fluctuating demand. Create an AWS Lambda function that changes instance sizes based on Amazon CloudWatch alarms. Have each team upload their bill to an Amazon S3 bucket for analysis of team spending. Use Spot instances on nightly batch processing jobs.
- B. Enable Cost Explorer and AWS Business Support Reserve Amazon EC2 and Amazon RDS DB instances. Use Amazon CloudWatch and AWS Trusted Advisor for monitoring and to receive cost-savings suggestions. Create a master account under Organizations and have teams join for consolidated billing.
- C. Enable AWS Business Support and review AWS Trusted Advisor's cost checks. Create Amazon EC2 Auto Scaling groups for applications that experience fluctuating demand. Save AWS Simple Monthly Calculator reports in Amazon S3 for trend analysis. Create a master account under Organizations and have teams join for consolidating billing.
- D. Create an AWS Lambda function that changes the instance size based on Amazon CloudWatch alarms.
Reserve instances based on AWS Simple Monthly Calculator suggestions. Have an AWS Well-Architected framework review and apply recommendations. Create a master account under Organizations and have teams join for consolidated billing.

NEW QUESTION # 197
A solutions architect is building a web application that uses an Amazon RDS for PostgreSQL DB instance The DB instance is expected to receive many more reads than writes The solutions architect needs to ensure that the large amount of read traffic can be accommodated and that the DB instance is highly available.
Which steps should the solutions architect take to meet these requirements? (Select THREE.)
- A. Create multiple read replicas and put them into an Auto Scaling group
- B. Configure an Amazon CloudWatch alarm to detect a failed read replica Set the alarm to directly invoke an AWS Lambda function to delete its Route 53 record set.
- C. Create an Application Load Balancer (ALBJ and put the read replicas behind the ALB.
- D. Create multiple read replicas in different Availability Zones.
- E. Configure an Amazon Route 53 health check for each read replica using its endpoint
- F. Create an Amazon Route 53 hosted zone and a record set for each read replica with a TTL and a weighted routing policy
Answer: D,E,F
Explanation:
Explanation
https://aws.amazon.com/premiumsupport/knowledge-center/requests-rds-read-replicas/ You can use Amazon Route 53 weighted record sets to distribute requests across your read replicas. Within a Route 53 hosted zone, create individual record sets for each DNS endpoint associated with your read replicas and give them the same weight. Then, direct requests to the endpoint of the record set. You can incorporate Route 53 health checks to be sure that Route 53 directs traffic away from unavailable read replicas
