A company is building a new web platform where user requests trigger an AWS Lambda function that performs an insert into an Amazon Aurora MySQL DB cluster. Initial tests with less than 10 users on the new platform yielded successful execution and fast response times. However, upon more extensive tests with the actual target of 3,000 concurrent users, Lambda functions are unable to connect to the DB cluster and receive too many connections errors.
Which of the following will resolve this issue?

• A.Edit the my.cnf file for the DB cluster to increase max_connections
• B.Increase the instance size of the DB cluster
• C.Change the DB cluster to Multi-AZ
• D.Increase the number of Aurora Replicas

A company stores critical data for a department in Amazon RDS for MySQL DB instances. The department was closed for 3 weeks and notified a database specialist that access to the RDS DB instances should not be granted to anyone during this time. To meet this requirement, the database specialist stopped all the DB instances used by the department but did not select the option to create a snapshot. Before the 3 weeks expired, the database specialist discovered that users could connect to the database successfully.
What could be the reason for this?

• A.When stopping the DB instance, the option to create a snapshot should have been selected.
• B.When stopping the DB instance, the duration for stopping the DB instance should have been selected.
• C.Stopped DB instances will automatically restart if the number of attempted connections exceeds the threshold set.
• D.Stopped DB instances will automatically restart if the instance is not manually started after 7 days.

A company's database specialist disabled TLS on an Amazon DocumentDB cluster to perform benchmarking tests. A few days after this change was implemented, a database specialist trainee accidentally deleted multiple tables. The database specialist restored the database from available snapshots. An hour after restoring the cluster, the database specialist is still unable to connect to the new cluster endpoint.
What should the database specialist do to connect to the new, restored Amazon DocumentDB cluster?

• A.Change the restored cluster's parameter group to the original cluster's custom parameter group.
• B.Change the restored cluster's parameter group to the Amazon DocumentDB default parameter group.
• C.Configure the interface VPC endpoint and associate the new Amazon DocumentDB cluster.
• D.Run the syncInstances command in AWS DataSync.

A database specialist deployed an Amazon RDS DB instance in Dev-VPC1 used by their development team. Dev-VPC1 has a peering connection with Dev-VPC2 that belongs to a different development team in the same department. The networking team confirmed that the routing between VPCs is correct; however, the database engineers in Dev-VPC2 are getting a timeout connections error when trying to connect to the database in Dev- VPC1.
What is likely causing the timeouts?

• A.The database is deployed in a VPC that is in a different Availability Zone.
• B.The database is deployed with the wrong client connect timeout configuration.
• C.The database is deployed in a VPC that is in a different Region.
• D.The database is deployed with misconfigured security groups.

Amazon RDS for Oracle with Transparent Data Encryption is used by a financial services organization (TDE). At all times, the organization is obligated to encrypt its data at rest. The decryption key must be widely distributed, and access to the key must be restricted. The organization must be able to rotate the encryption key on demand to comply with regulatory requirements. If any possible security vulnerabilities are discovered, the organization must be able to disable the key. Additionally, the company's overhead must be kept to a minimal.
What method should the database administrator use to configure the encryption to fulfill these specifications?

• A.AWS CloudHSM
• B.AWS Key Management Service (AWS KMS) with an AWS managed key
• C.AWS Key Management Service (AWS KMS) with server-side encryption
• D.AWS Key Management Service (AWS KMS) CMK with customer-provided material
