   2. CloudWatch Console
   3. CloudTrail Console
   4. Trusted Advisor Console

3. How can you access Amazon CloudWatch?

   2. Amazon S3
   3. Amazon EC2 Auto Scaling
   4. Amazon VPC

5. Which of the following are valid alarm states for Amazon CloudWatch? (Choose three.)

   1. ALARM
   2. OK
   3. READY
   4. INSUFFICIENT_DATA
   5. OFFLINE
   6. WARNING

6. You have been asked to create Amazon CloudWatch alarms for each of your organization's 600 servers, which all reside within the same region. Assuming you create five alarms per server, will you be able to create alarms for each of the servers?

   1. Yes, because the limit is 5000 alarms per region.
   2. Yes, because the limit is 3500 alarms per region.
   3. Yes, because the limit is 10,000 alarms per region.
   4. No, you can't create that many alarms in a single region.

7. You are a system administrator at your company, and you have been asked to check why an existing Amazon CloudWatch alarm is showing INSUFFICIENT_DATA for one of your established servers. What is the best explanation for why this is occurring?

   1. CloudWatch is experiencing an outage.
   2. Not enough data is available for the metric to determine whether it should be OK or ALARM.
   3. The alarm has only just been started, so it doesn't have enough data to determine if the state should be OK or ALARM.
   4. The server is offline so no metrics are available.

8. You are a system administrator at your company, and you have been asked to check why a new Amazon CloudWatch alarm is showing INSUFFICIENT_DATA for one of your established servers. What is the best explanation for why this is occurring?

   1. CloudWatch is experiencing an outage.
   2. Not enough data is available for the metric to determine whether it should be OK or ALARM.
   3. The alarm has only just been started, so it doesn't have enough data to determine if the state should be OK or ALARM.
   4. The server is offline so no metrics are available.

9. Your bosses have come to you and have asked you if there is a way for them to get real-time notifications if a certain Amazon CloudWatch alarm is triggered. What should your bosses do to ensure that they can get real-time notifications? The answer should minimize administrative overhead.

   1. Subscribe to an SNS topic that will send an SMS text message when the Amazon CloudWatch alarm is triggered.
   2. Write a custom AWS Lambda function that will send an email when the Amazon CloudWatch alarm is triggered.
   3. Use an SQS queue to deliver messages when an Amazon CloudWatch alarm is triggered.
   4. Use a third-party solution to send notifications via SMS text message when an Amazon CloudWatch alarm is triggered.

10. You need to set up an Amazon CloudWatch alarm that will trigger after four failed evaluations of the alarm metrics in a 5-minute period. What do you need to set the evaluation period and the data points to alarm to so that you get the desired result?

    1. Data points to alarm should be set to 5. Evaluation period should be set to 1 minute.
    2. Data points to alarm should be set to 4. Evaluation period should be set to 5 minutes.
    3. Data points to alarm should be set to 5. Evaluation period should be set to 5 minutes.
    4. Data points to alarm should be set to 4. Evaluation period should be set to 1 minute.

11. Your boss has asked you to ensure that the 5-minute data points from CloudWatch are available for at least 60 days. What do you need to change within Amazon CloudWatch to ensure that you have at least 60 days' worth of 5-minute data points?

    1. Nothing, Amazon CloudWatch can't retain data points that long.
    2. Nothing. By default, Amazon CloudWatch keeps 5-minute data points for 63 days.
    3. Create an archive to maintain 5-minute data points for at least 60 days.
    4. Set Amazon CloudWatch to never delete the 5-minute data points.

12. What is a namespace in Amazon CloudFront?

    1. A logical grouping of Amazon CloudWatch metrics
    2. A logical grouping of Amazon CloudWatch alerts
    3. A logical grouping of Amazon CloudWatch logs
