Question : How can an EBS volume that is currently attached to an EC instance be migrated from one Availability Zone to another?
: How can an EBS volume that is currently attached to an EC instance be migrated from one Availability Zone to another?
1. Simply create a new volume in the other AZ and specify the original volume as the source.
2. Detach the volume, then use the ec2-migrate-volume command to move it to another AZ.

Explanation: snapshots can be used to create multiple new EBS volumes, expand the size of a volume, or move volumes across Availability Zones.
Only snapshots can be moved to another AZ





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?

Correct Answer : Get Lastest Questions and Answer :

Explanation: Both Elasticache and Read Replicas could help here, depending on the scenario. Elasticache is for caching previously used database queries, so if this question is asking about
frequent new queries, the answer has to be C. Based on the way the question is worded.





Question : You run a web application with the following components Elastic Load Balancer (ELB),
Web/Application servers, 1 MySQL RDS database with read replicas, and Amazon Simple
Storage Service (Amazon S3) for static content. Average response time for users is
increasing slowly.
What three CloudWatch RDS metrics will allow you to identify if the database is the
bottleneck? Choose 3 answers

A. The number of outstanding IOs waiting to access the disk.
B. The amount of write latency.
C. The amount of disk space occupied by binary logs on the master.
D. The amount of time a Read Replica DB Instance lags behind the source DB Instance
E. The average number of disk I/O operations per second.

Question : Your mission is to create a lights-out datacenter environment, and you plan to use AWS
OpsWorks to accomplish this. First you created a stack and added an App Server layer
with an instance running in it. Next you added an application to the instance, and now you
need to deploy a MySQL RDS database instance.
Which of the following answers accurately describe how to add a backend database server
to an OpsWorks stack? Choose 3 answers
A. Add a new database layer and then add recipes to the deploy actions of the database and App Server layers.
B. Use OpsWorks' "Clone Stack" feature to create a second RDS stack in another Availability Zone for redundancy in the event of a failure in the Primary AZ. To switch to the
secondary RDS instance, set the [:database] attributes to values that are appropriate for your server which you can do by using custom JSON.
C. The variables that characterize the RDS database connection--host, user, and so on--are set using the corresponding values from the deploy JSON's [:depioy][:app_name][:database] attributes.
D. Cookbook attributes are stored in a repository, so OpsWorks requires that the "password": "your_password" attribute for the RDS instance must be encrypted using at least a 256-bit key.
E. Set up the connection between the app server and the RDS layer by using a custom recipe. The recipe configures the app server as required, typically by creating a
configuration file. The recipe gets the connection data such as the host and database name from a set of attributes in the stack configuration and deployment JSON that AWS
OpsWorks installs on every instance.

Question : You have a proprietary data store on-premises that must be backed up daily by dumping
the data store contents to a single compressed 50GB file and sending the file to AWS. Your
SLAs state that any dump file backed up within the past 7 days can be retrieved within 2
hours. Your compliance department has stated that all data must be held indefinitely. The
time required to restore the data store from a backup is approximately 1 hour. Your onpremise
network connection is capable of sustaining 1gbps to AWS.
Which backup methods to AWS would be most cost-effective while still meeting all of your
requirements?
 : You have a proprietary data store on-premises that must be backed up daily by dumping
1. Send the daily backup files to Glacier immediately after being generated
2. Transfer the daily backup files to an EBS volume in AWS and take daily snapshots of the volume
