NEW QUESTION 31
When specifying more than one conditional requirements for a task, what is the proper method?

• A. - when: foo is "hello" and bar is "world"
• B. - when: foo == "hello" and bar == "world"
• C. - when: foo == "hello" - when: bar == "world"
• D. - when: foo == "hello" && bar == "world"

Answer: B

Explanation:
Ansible will allow you to stack conditionals using `and' and `or'. It requires it to be in the same
`when' statement, comparisons must be `==' for equals or `!=' for not equals and the `and/or' must be written as such, not `&&/||'.

NEW QUESTION 32
After conducting a disaster recovery exercise, an Enterprise Architect discovers that a large team of Database and Storage Administrators need more than seven hours of manual effort to make a flagship application's database functional in a different AWS Region. The Architect also discovers that the recovered database is often missing as much as two hours of data transactions.
Which solution provides improved RTO and RPO in a cross-region failover scenario?

• A. Deploy an Amazon RDS Multi-AZ instance backed by a multi-region Amazon EFS. Configure the RDS option group to enable multi-region availability for native automation of cross-region recovery and continuous data replication. Create an Amazon SNS topic subscribed to RDS-impacted events to send emails to the Database Administration team when significant query Latency is detected in a single Availability Zone.
• B. Create a scheduled Amazon CloudWatch Events rule to make a call to Amazon RDS to create a snapshot from a database instance and specify a frequency to match the RPO. Create an AWS Step Functions task to call Amazon RDS to perform a cross-region snapshot copy into the failover region, and configure the state machine to execute the task when the RDS snapshot create state is complete.
  Create an SNS topic subscribed to RDS availability events, and push these messages to an Amazon SQS queue located in the failover region. Configure an Auto Scaling group of worker nodes to poll the queue for new messages and make a call to Amazon RDS to restore a database from a snapshot after a checksum on the cross-region copied snapshot returns valid.
• C. Use Amazon SNS topics to receive published messages from Amazon RDS availability and backup events. Use AWS Lambda for three separate functions with calls to Amazon RDS to snapshot a database instance, create a cross-region snapshot copy, and restore an instance from a snapshot. Use a scheduled Amazon CloudWatch Events rule at a frequency matching the RPO to trigger the Lambda function to snapshot a database instance. Trigger the Lambda function to create a cross-region snapshot copy when the SNS topic for backup events receives a new message. Configure the Lambda function to restore an instance from a snapshot to trigger sending new messages published to the availability SNS topic.
• D. Use Amazon RDS scheduled instance lifecycle events to create a snapshot and specify a frequency to match the RPO. Use Amazon RDS scheduled instance lifecycle event configuration to perform a cross-region snapshot copy into the failover region upon SnapshotCreateComplete events. Configure Amazon CloudWatch to alert when the CloudWatch RDS namespace CPUUtilization metric for the database instance falls to 0% and make a call to Amazon RDS to restore the database snapshot in the failover region.

Answer: C

• C. Create an 1AM role for EC2 instances, assign it a policy that allows only the actions required tor the Saas application to work, provide the role ARN to the SaaS provider to use when launching their application instances.
• D. Create an 1AM user within the enterprise account assign a user policy to the 1AM user that allows only the actions required by the SaaS application. Create a new access and secret key for the user and provide these credentials to the SaaS provider.
