The previous AWS SysOps administrator in the Acme Corporation was using Amazon CloudWatch
dashboards, as he was able to monitor the resources in a single view, even those resources that are
spread across different Regions. Now, you took over the position as AWS SysOps administrator and
you are responsible to create a new CloudWatch dashboard using the console.
Which of the following steps is NOT required to create the new CloudWatch dashboard?

Correct Answer:C
Create at least two widgets to the dashboard is the correct answer. Amazon CloudWatch dashboards
are customizable home pages in the CloudWatch console that you can use to monitor your resources
in a single view, even those resources that are spread across different Regions. You can use
CloudWatch dashboards to create customized views of the metrics and alarms for your AWS
resources.
With dashboards, you can create the following:
* 1. A single view for selected metrics and alarms to help you assess the health of your resources and
applications across one or more regions. You can select the color used for each metric on each graph,
so that you can easily track the same metric across multiple graphs.
* 2. A common view of critical resource and application measurements that can be shared by team
members for faster communication flow during operational events.
To create a dashboard using the console
* 1. Open the CloudWatch console at https://console.aws.amazon.com/cloudwatch/.
* 2. In the navigation pane, choose Dashboards and then Create dashboard.
* 3. In the Create new dashboard dialog box, enter a name for the dashboard and choose Create
dashboard.If you use the name CloudWatch-Default, the dashboard appears on the overview on the
CloudWatch home page.
If you use resource groups and name the dashboard CloudWatch-Default-ResourceGroupName, it
appears on the CloudWatch home page when you focus on that resource group.
* 4. Do one of the following in the Add to this dashboard dialog box:
To add a graph to your dashboard, choose Line or Stacked area and choose Configure. In the Add
metric graph dialog box, select the metrics to graph and choose Create widget. If a specific metric
doesn’t appear in the dialog box because it hasn’t published data in more than 14 days, you can add
it manually.
To add a number displaying a metric to the dashboard, choose Number and then Configure. In
the Add metric graph dialog box, select the metrics to graph and choose Create widget.
To add a text block to your dashboard, choose Text and then Configure. In the New text widget
dialog box, for Markdown, add and format your text using Markdown. Choose Create widget.
* 5. Optionally, choose Add widget and repeat step 4 to add another widget to the dashboard. You can
repeat this step multiple times.
* 6. Choose Save dashboard.

A company's SysOps administrator has created an Amazon EC2 instance with custom software that will be used as a template for all new EC2 instances across multiple AWS accounts. The Amazon Elastic Block Store (Amazon EBS) volumes that are attached to the EC2 instance are encrypted with AWS managed keys.
The SysOps administrator creates an Amazon Machine Image (AMI) of the custom EC2 instance and plans to share the AMI with the company's other AWS accounts. The company requires that all AMIs are encrypted with AWS Key Management Service (AWS KMS) keys and that only authorized AWS accounts can access the shared AMIs.
Which solution will securely share the AMI with the other AWS accounts?

Correct Answer:C

A company uses an Amazon Elastic File System (Amazon EFS) file system to share files across many Linux Amazon EC2 instances. A SysOps administrator notices that the file system's PercentIOLimit metric is consistently at 100% for 15 minutes or longer. The SysOps administrator also notices that the application that reads and writes to that file system is performing poorly. They application requires high throughput and IOPS while accessing the file system.
What should the SysOps administrator do to remediate the consistently high PercentIOLimit metric?

Correct Answer:A
