Question 103

An International company has deployed a multi-tier web application that relies on DynamoDB in a single region For regulatory reasons they need disaster recovery capability In a separate region with a Recovery Time Objective of 2 hours and a Recovery Point Objective of 24 hours They should synchronize their data on a regular basis and be able to provision me web application rapidly using CIoudFormation.
The objective is to minimize changes to the existing web application, control the throughput of DynamoDB used for the synchronization of data and synchronize only the modified elements.
Which design would you choose to meet these requirements?

A. Use AWS data Pipeline to schedule a DynamoDB cross region copy once a da
B. create a Last updated' attribute in your DynamoDB table that would represent the timestamp of the last update and use it as a filter.
C. Use EMR and write a custom script to retrieve data from DynamoDB in the current region using a SCAN operation and push it to Dynamo DB in the second region.
D. Use AWS data Pipeline to schedule an export of the DynamoDB table to 53 in the current region once a day then schedule another task immediately after it that will import data from 53 to DynamoDB in the other region.
E. Send also each Ante into an SOS queue in me second region; use an auto-scaling group behind the SOS queue to replay the write in the second region.

Correct Answer:A

Question 104

You have just set up a large site for a client which involved a huge database which you set up with Amazon RDS to run as a Mu|ti-AZ deployment. You now start to worry about what will happen if the database instance fails. Which statement best describes how this database will function if there is a database failure?

A. Updates to your DB Instance are synchronously replicated across Availability Zones to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.
B. Your database will not resume operation without manual administrative intervention.
C. Updates to your DB Instance are asynchronously replicated across Availability Zones to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.
D. Updates to your DB Instance are synchronously replicated across S3 to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.

Correct Answer:A
Amazon Relational Database Service (Amazon RDS) is a managed service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity, while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.
When you create or modify your DB Instance to run as a MuIti-AZ deployment, Amazon RDS automatically provisions and maintains a synchronous "standby" replica in a different Availability Zone. Updates to your DB Instance are synchronously replicated across Availability Zones to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.
During certain types of planned maintenance, or in the unlikely event of DB Instance failure or Availability Zone failure, Amazon RDS will automatically failover to the standby so that you can resume database writes and reads as soon as the standby is promoted. Since the name record for your DB Instance
remains the same, you application can resume database operation without the need for manual administrative intervention. With Mu|ti-AZ deployments, replication is transparent: you do not interact directly with the standby, and it cannot be used to serve read traffic. If you are using Amazon RDS for MySQL and are looking to scale read traffic beyond the capacity constraints of a single DB Instance, you can deploy one or more Read Replicas.

Question 105

You have been asked to set up monitoring of your network and you have decided that Cloudwatch would be the best service to use. Amazon CIoudWatch monitors your Amazon Web Services (AWS) resources and the applications you run on AWS in real-time. You can use CIoudWatch to collect and track metrics, which are the variables you want to measure for your resources and applications. Which of the following items listed can AWS Cloudwatch monitor?

A. Log files your applications generate.
B. All of the items listed on this page.
C. System-wide visibility into resource utilization, application performance, and operational health.
D. Custom metrics generated by your applications and services .

Correct Answer:B
Amazon CIoudWatch can monitor AWS resources such as Amazon EC2 instances, Amazon DynamoDB tables, and Amazon RDS DB instances, as well as custom metrics generated by your applications and services, and any log files your applications generate. You can use Amazon CIoudWatch to gain
system-wide visibility into resource utilization, application performance, and operational health. You can use these insights to react and keep your application running smoothly.
