Correct Answer : Get Lastest Questions and Answer :

Explanation: Amazon RDS performs maintenance on the DB instance during a user-definable maintenance window. The system may be offline or experience
lower performance during that window. The only maintenance events that may require RDS to make the DB instance offline are:
Scaling compute operations
Software patching. Required software patching is automatically scheduled only for patches that are security
and durability related. Such patching occurs infrequently (typically once every few months. and seldom
requires more than a fraction of the maintenance window.

Correct Answer : Get Lastest Questions and Answer :

Explanation: AWS Identity and Access Management is a web service which allows organizations to manage users and user permissions for various AWS
services. The user can add conditions as a part of the IAM policies. The condition can be set on AWS Tags, Time, and Client IP as well as on
various parameters. If the organization wants the user to access only specific instances he should define proper tags and add to the IAM policy
condition. The sample policy is shown below.
"Statement": [
{
"Action": "ec2:*",
"Effect": "Allow",
"Resource": "*",
"Condition": {
"StringEquals": {
"ec2:ResourceTag/InstanceType": "Production"
}
}
}
]









Question : A user has configured Auto Scaling with the minimum capacity as and the desired capacity as . The user is trying to terminate one of the
existing instance with the command:
as-terminate-instance-in-auto-scaling-group (Instance ID) --decrement-desired-capacity
What will Auto Scaling do in this scenario?
: A user has configured Auto Scaling with the minimum capacity as and the desired capacity as . The user is trying to terminate one of the
1. Terminates the instance and does not launch a new instance
2. Terminates the instance and updates the desired capacity to 1
 3. Access Mostly Uused Products by 50000+ Subscribers
4. Throws an error

Correct Answer : Get Lastest Questions and Answer :


Explanation: The Auto Scaling command as-terminate-instance-in-auto-scaling-group (Instance ID) will terminate the
specific instance ID. The user is required to specify the parameter as --decrement-desired- capacity. Then Auto Scaling will terminate the instance
and decrease the desired capacity by 1. In this case since the minimum size is 2, Auto Scaling will not allow the desired capacity to go below
2. Thus, it will throw an error.

Question : Your business is building a new application that will store its entire customer database on a
RDS MySQL database, and will have various applications and users that will query that
data for different purposes.
Large analytics jobs on the database are likely to cause other applications to not be able to
get the query results they need to, before time out. Also, as your data grows, these
analytics jobs will start to take more time, increasing the negative effect on the other
applications.
How do you solve the contention issues between these different workloads on the same
data?
