It is currently running on a highly customized. Windows VM within a VMware environment: You do not have me installation media
This is a mission critical application with an RTO (Recovery Time Objective) of 8 hours. RPO (Recovery Point Objective) of 1 hour. How could you best migrate this application to AWS while meeting your business continuity requirements?
A. Use the EC2 VM Import Connector for vCenter to import the VM into EC2.
B. Use Import/Export to import the VM as an ESS snapshot and attach to EC2.
C. Use 53 to create a backup of the VM and restore the data into EC2.

Q105. You are running a successful multitier web application on AWS and your marketing department has asked you to add a reporting tier to the application. The reporting tier will aggregate and publish status reports every 30 minutes from user-generated information that is being stored in your web application s database. You are currently running a MuIti-AZ RDS MySQL instance for the database tier. You also have implemented Elasticache as a database caching layer between the application tier and database tier. Please select the answer that will allow you to successful ly implement the reporting tier with as little impact as possible to your database.
A. Continually send transaction logs from your master database to an 53 bucket and generate the reports off the 53 bucket using 53 byte range request s.
B. Generate the reports by querying the synchronously replicated standby RDS MySQL instance maintained through Multi-AZ.
C. Launch a RDS Read Replica connected to your MuIti AZ master database and generate reports by querying the Read Replica.
D. Generate the reports by querying the EIastiCache database caching tier.
Answer: C
Explanation:
Amazon RDS allows you to use read replicas with MuIti-AZ deployments. In Multi-AZ deployments for MySQL, Oracle, SQL Server, and PostgreSQL, the data in your primary DB Instance is synchronously replicated to a standby instance in a different Availability Zone (AZ). Because of their synchronous replication, MuIti-AZ deployments for these engines offer greater data durability benefits than do read replicas. (In all Amazon RDS for Aurora deployments, your data is automatically replicated across 3 Availability Zones.)
You can use MuIti-AZ deployments and read replicas in conjunction to enjoy the complementary benefits of each. You can simply specify that a given Multi-AZ deployment is the source DB Instance for your Read replicas. That way you gain both the data durability and availability benefits of Multi -AZ deployments and the read scaling benefits of read replicas.
Note that for MuIti-AZ deployments, you have the option to create your read replica in an AZ other than that of the primary and the standby for even more redundancy. You can identify the AZ corresponding to your standby by looking at the "Secondary Zone" field of your DB Instance in the AWS Management Console.
Q106. A user is sending bulk emails using AWS SES. The emails are not reaching some of the targeted audience because they are not authorized by the ISPs. How can the user ensure that the emails are all delivered?

B. Send an email using SMTP with SES.
C. Open a ticket with AWS support to get it authorized with the ISP.
D. Authorize the ISP by sending emails from the development account.
Answer: A
Explanation:
Domain Keys Identified MaiI (DKIM) is a standard that allows senders to sign their email messages and ISPs, and use those signatures to verify that those messages are legitimate and have not been modified by a third party in transit.
