• Minimum size

• Health checks

• Desired capacity

• Launch configuration

You have created an Elastic Load Balancing load balancer listening on port 80, and you registered it with a single Amazon Elastic Compute Cloud (Amazon EC2) instance also listening on port 80. A client makes a request to the load balancer with the correct protocol and port for the load balancer. In this scenario, how many connections does the balancer maintain?

• 1

• 2

• 3

• 4

How long does Amazon CloudWatch keep metric data?

• 1 day

• 2 days

• 1 week

• 2 weeks

Which of the following are the minimum required elements to create an Auto Scaling launch configuration?

• Launch configuration name, Amazon Machine Image (AMI), and instance type

• Launch configuration name, AMI, instance type, and key pair

• Launch configuration name, AMI, instance type, key pair, and security group

• Launch configuration name, AMI, instance type, key pair, security group, and block device mapping

You are responsible for the application logging solution for your company’s existing applications running on multiple Amazon EC2 instances. Which of the following is the best approach for aggregating the application logs within AWS?

• Amazon CloudWatch custom metrics

• Amazon CloudWatch Logs Agent

• An Elastic Load Balancing listener

• An internal Elastic Load Balancing load balancer

Which of the following must be configured on an Elastic Load Balancing load balancer to accept incoming traffic?

• A port

• A network interface

• A listener

• An instance

You create an Auto Scaling group in a new region that is configured with a minimum size value of 10, a maximum size value of 100, and a desired capacity value of 50. However, you notice that 30 of the Amazon Elastic Compute Cloud (Amazon EC2) instances within the Auto Scaling group fail to launch. Which of the following is the cause of this behavior?

• You cannot define an Auto Scaling group larger than 20.

• The Auto Scaling group maximum value cannot be more than 20.

• You did not attach an Elastic Load Balancing load balancer to the Auto Scaling group.

• You have not raised your default Amazon EC2 capacity (20) for the new region.

You want to host multiple Hypertext Transfer Protocol Secure (HTTPS) websites on a fleet of Amazon EC2 instances behind an Elastic Load Balancing load balancer with a single X.509 certificate. How must you configure the Secure Sockets Layer (SSL) certificate so that clients connecting to the load balancer are not presented with a warning when they connect?

• Create one SSL certificate with a Subject Alternative Name (SAN) value for each website name.

• Create one SSL certificate with the Server Name Indication (SNI) value checked.

• Create multiple SSL certificates with a SAN value for each website name.

• Create SSL certificates for each Availability Zone with a SAN value for each website name.

Your web application front end consists of multiple Amazon Compute Cloud (Amazon EC2) instances behind an Elastic Load Balancing load balancer. You have configured the load balancer to perform health checks on these Amazon EC2 instances. If an instance fails to pass health checks, which statement will be true?

• The instance is replaced automatically by the load balancer.

• The instance is terminated automatically by the load balancer.

• The load balancer stops sending traffic to the instance that failed its health check.

• The instance is quarantined by the load balancer for root cause analysis.

In the basic monitoring package for Amazon Elastic Compute Cloud (Amazon EC2), what Amazon CloudWatch metrics are available?

• Web server visible metrics such as number of failed transaction requests

• Operating system visible metrics such as memory utilization

• Database visible metrics such as number of connections

• Hypervisor visible metrics such as CPU utilization
