Question 6

When attached to an Amazon VPC, which two components provide connectivity with external networks? (Choose two.)

  1. Elastic IPS (EIP)
  2. NAT Gateway (NAT)
  3. Internet Gateway {IGW)
  4. Virtual Private Gateway (VGW)

Question 7

Your application currently leverages AWS Auto Scaling to grow and shrink as load Increases/ decreases and has been performing well. Your marketing team expects a steady ramp up in traffic to follow an upcoming campaign that will result in a 20x growth in traffic over 4 weeks. Your forecast for the approximate number of Amazon EC2 instances necessary to meet the peak demand is 175. What should you do to avoid potential service disruptions during the ramp up in traffic?

  1. Ensure that you have pre-allocated 175 Elastic IP addresses so that each server will be able to obtain one as it launches
  2. Check the service limits in Trusted Advisor and adjust as necessary so the forecasted count remains within limits.
  3. Change your Auto Scaling configuration to set a desired capacity of 175 prior to the launch of the marketing campaign
  4. Pre-warm your Elastic Load Balancer to match the requests per second anticipated during peak demand prior to the marketing campaign

Question 8

You have an Auto Scaling group associated with an Elastic Load Balancer (ELB). You have noticed that instances launched via the Auto Scaling group are being marked unhealthy due to an ELB health check, but these unhealthy instances are not being terminated. What do you need to do to ensure trial instances marked unhealthy by the ELB will be terminated and replaced?

  1. Change the thresholds set on the Auto Scaling group health check
  2. Add an Elastic Load Balancing health check to your Auto Scaling group
  3. Increase the value for the Health check interval set on the Elastic Load Balancer
  4. Change the health check set on the Elastic Load Balancer to use TCP rather than HTTP checks

Question 9

Which two AWS services provide out-of-the-box user configurable automatic backup-as-a-service and backup rotation options? (Choose two.)

  1. Amazon S3
  2. Amazon RDS
  3. Amazon EBS
  4. Amazon Red shift

Question 10

An organization has configured a VPC with an Internet Gateway (IGW). pairs of public and private subnets (each with one subnet per Availability Zone), and an Elastic Load Balancer (ELB) configured to use the public subnets. The application s web tier leverages the ELB. Auto Scaling and a mum-AZ RDS database instance The organization would like to eliminate any potential single points ft failure in this design. What step should you take to achieve this organization's objective?

  1. Nothing, there are no single points of failure in this architecture.
  2. Create and attach a second IGW to provide redundant internet connectivity.
  3. Create and configure a second Elastic Load Balancer to provide a redundant load balancer.
  4. Create a second multi-AZ RDS instance in another Availability Zone and configure replication to provide a redundant database.
