2) duplicating a table across multiple hosts and then using a hashing algorithm to determine which host
receives a given update.

Question 112

A corporate web application is deployed within an Amazon Virtual Private Cloud (VPC) and is connected to the corporate data center via an IPsec VPN. The application must authenticate against the on-premises LDAP server. After authentication, each logged-in user can only access an Amazon Simple Storage Space (53) keyspace specific to that user.
Which two approaches can satisfy these objectives? (Choose 2 answers)

A. Develop an identity broker that authenticates against IAM security Token service to assume a Lam role in order to get temporary AWS security credentials The application calls the identity broker to get AWS temporary security credentials with access to the appropriate 53 bucket.
B. The application authenticates against LDAP and retrieves the name of an IAM role associated with the use
C. The application then ca Ils the IAM Security Token Service to assume that IAM role The application can use the temporary credentials to access the appropriate 53 bucket.
D. Develop an identity broker that authenticates against LDAP and then calls IAM Security To ken Service to get IAM federated user credentials The application calls the identity broker to get IAM federated user credentials with access to the appropriate 53 bucket.
E. The application authenticates against LDAP the application then calls the AWS identity and Access Management (IAM) Security service to log in to IAM using the LDAP credentials the application can use the IAM temporary credentials to access the appropriate 53 bucket.
F. The application authenticates against IAM Security Token Service using the LDAP credentials the application uses those temporary AWS security credentials to access the appropriate 53 bucket.

Question 113

You have three Amazon EC2 instances with Elastic IP addresses in the US East (Virginia) region, and you want to distribute requests across all three IPs evenly for users for whom US East (Virginia) is the appropriate region.
How many EC2 instances would be sufficient to distribute requests in other regions?

A. 3
B. 9
C. 2
D. 1

Correct Answer:D
If your application is running on Amazon EC2 instances in two or more Amazon EC2 regions, and if you have more than one Amazon EC2 instance in one or more regions, you can use latency-based routing to route traffic to the correct region and then use weighted resource record sets to route traffic to instances within the region based on weights that you specify.
For example, suppose you have three Amazon EC2 instances with Elastic IP addresses in the US East (Virginia) region and you want to distribute requests across all three IPs evenly for users for whom US East (Virginia) is the appropriate region. Just one Amazon EC2 instance is sufficient in the other regions, although you can apply the same technique to many regions at once.
