Which AWS service should the company use to ensure that there are enough instances to meet the surges in demand?

  A. AWS Lambda

  B. Amazon EventBridge (Amazon CloudWatch Events)

  C. Elastic Load Balancing (ELB)

  D. Amazon EC2 Auto Scaling

  Correct Answer: D

  D. Amazon EC2 Auto Scaling

  Amazon EC2 Auto Scaling is a service that enables the company to automatically scale the number of Amazon Elastic Compute Cloud (EC2) instances in its application up or down, in response to changes in demand. The company can use Auto Scaling to ensure that there are enough instances to handle the surges in traffic that occur every weekend. The company can create a schedule to automatically increase the number of instances in the fleet before the surge in traffic occurs, and then automatically decrease the number of instances after the surge in traffic subsides. This will ensure

  that there are enough instances to handle the increased demand, while also keeping costs under control by not having excess instances running when they are not needed. Additionally, the company can use CloudWatch Alarms to monitor the performance of the instances and the load balancer to trigger the scaling process.

• Question 168:

  Which AWS service or tool is associated with an Amazon EC2 instance and acts as a virtual firewall to control inbound and outbound traffic?

  A. AWS WAF

  B. AWS Shield

  C. Network access control list (ACL)

  D. Security group

  Correct Answer: D

  D. Security group

  A security group is an AWS service or tool that is associated with an Amazon EC2 instance and acts as a virtual firewall to control inbound and outbound traffic. Security groups enable you to specify which traffic is allowed to reach your instances, based on a set of rules that you define. Security groups act at the instance level, not the subnet level, so each instance in a subnet in your VPC must be associated with a security group. You can add or remove rules from a security group at any time, and you can associate multiple security groups with a single instance.

  AWS WAF is a web application firewall that helps protect web applications from common web exploits, AWS Shield is a service that provides DDoS protection for web applications hosted on AWS, and Network access control list (ACL) is another service that controls traffic in and out of a VPC, but it acts at the subnet level, not the instance level like security groups.

  A. Users eliminate the need to guess about infrastructure capacity requirements.

  B. Users decrease their variable costs by maintaining sole ownership of IT hardware.

  C. Users maintain control of underlying IT infrastructure hardware.

  D. Users maintain control of operating systems for managed services.

  Correct Answer: A

  Stop guessing capacity ?Eliminate guessing on your infrastructure capacity needs. When you make a capacity decision prior to deploying an application, you often end up either sitting on expensive idle resources or dealing with limited capacity. With cloud computing, these problems go away. You can access as much or as little capacity as you need, and scale up and down as required with only a few minutes' notice.
