The company needs to build the site such that can handle the rapid influx of traffic while maintaining good performance but also wants to keep costs to a minimum. Which of the design patterns below should they use?

A. Use Cloud Front and an Elastic Load balancer in front of an auto-scaled set of web servers, the web servers will first can the Login With Amazon service to authenticate the user then process the users vote and store the result into a multi-AZ Relational Database Service instance.
B. Use CIoudFront and the static website hosting feature of 53 with the Javascript SDK to call the Login With Amazon service to authenticate the user, use IAM Roles to gain permissions to a DynamoDB table to store the users vote.
C. Use Cloud Front and an Elastic Load Balancer in front of an auto-scaled set of web servers, the web servers will first call the Login with Amazon service to authenticate the user, the web servers will process the users vote and store the result into a DynamoDB table using IAM Roles for EC2 instances to gain permissions to the DynamoDB table.
D. Use Cloud Front and an Elastic Load Balancer in front of an auto-scaled set of web servers, the web servers will first call the Logi
E. With Amazon service to authenticate the user, the web sewers win process the users vote and store the result into an SQS queue using IAM Roles for EC2 Instances to gain permissions to the SQS queu
F. A set of application sewers will then retrieve the items from the queue and store the result into a DynamoDB table.

Question 168

A user has created a subnet in VPC and launched an EC2 instance within it. The user has not selected the option to assign the IP address while launching the instance. The user has 3 elastic IPs and is trying to assign one of the Elastic IPs to the VPC instance from the console. The console does not show any instance in the IP assignment screen. What is a possible reason that the instance is unavailable in the assigned IP console?

A. The IP address may be attached to one of the instances
B. The IP address belongs to a different zone than the subnet zone
C. The user has not created an internet gateway
D. The IP addresses belong to EC2 Classic; so they cannot be assigned to VPC

Correct Answer:D
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. A user can create a subnet with VPC and launch instances inside that subnet. When the user is launching an instance he needs to select an option which attaches a public IP to the instance. If the user has not selected the option to attach the public IP then it will only have a private IP when launched. If the user wants to connect to
an instance from the internet he should create an elastic IP with VPC. If the elastic IP is a part of EC2
Classic it cannot be assigned to a VPC instance.
