Explanation: Common Features of Alarms
You can create up to 5000 alarms per AWS account. To create or update an alarm, you use the PutMetricAlarm API function (mon-put-metric-alarm command).
You can list any or all of the currently configured alarms, and list any alarms in a particular state using the DescribeAlarms API (mon-describe-alarms
command). You can further filter the list by time range.
You can disable and enable alarms by using the DisableAlarmActions and EnableAlarmActions APIs (mon-disable-alarm-actions and mon-enable-alarm-actions
commands).
You can test an alarm by setting it to any state using the SetAlarmState API (mon-set-alarm-state command). This temporary state change lasts only until
the next alarm comparison occurs.
Finally, you can view an alarm's history using the DescribeAlarmHistory API (mon-describe-alarm-history command). CloudWatch preserves alarm history for
two weeks. Each state transition is marked with a unique time stamp. In rare cases, your history might show more than one notification for a state
change. The time stamp enables you to confirm unique state changes.
Note
Some AWS resources do not send metric data to CloudWatch under certain conditions.
For example, Amazon EBS may not send metric data for an available volume that is not attached to an Amazon EC2 instance, because there is no metric activity
to be monitored for that volume. If you have an alarm set for such a metric, you may notice its state change to Insufficient Data. This may simply be an
indication that your resource is inactive, and may not necessarily mean that there is a problem.
Question : You have two Elastic Compute Cloud (EC) instances inside a Virtual Private Cloud (VPC) in the
same Availability Zone (AZ) but in different subnets.One instance is running a database and the
other instance an application that will interface with the database. You want to confirm that they
can talk to each other for your application to work properly.
Which two things do we need to confirm in the VPC settings so that these EC2 instances can
communicate inside the VPC?
Choose 2 answers
A. A network ACL that allows communication between the two subnets.
B. Both instances are the same instance class and using the same Key-pair.
C. That the default route is set to a NAT instance or internet Gateway (IGW) for them to communicate.
D. Security groups are set to allow the application host to talk to the database on the right port/protocol.

Question : How different is creating an Amazon RDS Reserved Instance from creating an Amazon RDS On-Demand Instance?
1. Both has to be configured differently
2. There is no difference
3. Access Mostly Uused Products by 50000+ Subscribers
4. On_demand has DB Parameter Groups but reserved instance has optional DB Parameter Groups
Correct Answer : Get Lastest Questions and Answer :
Explanation: Reserved DB instances let you make a one time up front payment for a DB instance and reserve the DB instance for a one or three y ear term at
significantly lower rates.
There is no difference in creating an Amazon RDS Reserved Instance from creating an Amazon RDS On-Demand Instance.
Reserved Instances are available in three varieties Heavy Utilization, Medium Utilization, and Light Utilization that enable you to optimize your Amazon RDS
costs based on your expected utilization

Question : Select the correct statement which applies for when you change the DB Subnet Group of your DB Instance?
1. An existing DB Subnet Group can be updated to add more subnets, either for existing Availability Zones or for new Availability Zones added since the
creation of the DB Instance.
2. Removing subnets from an existing DB Subnet Group can cause unavailability for instances if they are running in a particular AZ that gets removed from
the subnet group

Question : Select the correct statement which applies to encrypt connections between your application and your DB Instance using SSL
1. This option is currently only supported for the MySQL, SQL Server, Oracle and PostgreSQL engines.
2. Amazon RDS generates an SSL certificate for each DB Instance. Once an encrypted connection is established, data transferred between the DB Instance and
your application will be encrypted during transfer.

4. SSL support within Amazon RDS is for encrypting the connection between your application and your DB Instance; it should not be relied on for
authenticating the DB Instance itself.
5. SSL encryption is a compute-intensive operation and will increase the latency of your database connection
