Here Are Some Useful Questions:
01. A database specialist is troubleshooting complaints from an application’s users who are experiencing performance issues when saving data in an Amazon ElastiCache for Redis cluster with cluster mode disabled.
The database specialist finds that the performance issues are occurring during the cluster’s backup window. The cluster runs in a replication group containing three nodes. Memory on the nodes is fully utilized. Organizational policies prohibit the database specialist from changing the backup window time.
How could the database specialist address the performance concern?
(Select TWO.)
a) Add an additional node to the cluster in the same Availability Zone as the primary.
b) Configure the backup job to take a snapshot of a read replica.
c) Increase the local instance storage size for the cluster nodes.
d) Increase the reserved-memory-percent parameter value.
e) Configure the backup process to flush the cache before taking the backup.
Answer: b, d
02. A medical company is planning to migrate its on-premises PostgreSQL database, along with application and web servers, to AWS.
Amazon RDS for PostgreSQL is being considered as the target database engine. Access to the database should be limited to application servers and a bastion host in a VPC.
Which solution meets the security requirements?
a) Launch the RDS for PostgreSQL database in a DB subnet group containing private subnets. Modify the pg_hba.conf file on the DB instance to allow connections from only the application servers and bastion host.
b) Launch the RDS for PostgreSQL database in a DB subnet group containing public subnets. Create a new security group with inbound rules to allow connections from only the security groups of the application servers and bastion host. Attach the new security group to the DB instance.
c) Launch the RDS for PostgreSQL database in a DB subnet group containing private subnets. Create a new security group with inbound rules to allow connections from only the security groups of the application servers and bastion host. Attach the new security group to the DB instance.

When a new AWS account is created, the developers require full privileges for a database environment that uses the same configuration, data schema, and source data as the company’s production Amazon RDS for MySQL DB instance.
How can the operations team achieve this?
a) Enable the source DB instance to be shared with the new account so the development team may take a snapshot. Create an AWS CloudFormation template to launch the new DB instance from the snapshot.
