  A company is running a batch analysis every hour on their main transactional DB, running on an RDS MySQL instance to populate their central Data Warehouse running on Redshift. During the execution of the batch their transactional applications are very slow. When the batch completes they need to update the top management dashboard with the new data. The dashboard is produced by another system running on-premises that is currently started when a manually-sent email notifies that an update is required. The on-premises system cannot be modified because it is managed by another team. How would you optimize this scenario to solve performance issues and automate the process as much as possible?

  • AReplace RDS with Redshift for the batch analysis and SNS to notify the on-premises system to update the dashboard.
  • BReplace RDS with Redshift for the batch analysis and SQS to send a message to the on-premises system to update the dashboard.
  • CCreate an RDS Read Replica for the batch analysis and SNS to notify the on-premises system to update the dashboard.
  • DCreate an RDS Read Replica for the batch analysis and SQS to send a message to the on-premises system to update the dashboard.

  Which of the following is not a true statement relating to the performance of your EBS volumes?

  • AFrequent snapshots provide a higher level of data durability and they will not degrade the performance of your application while the snapshot is in progress.
  • BGeneral Purpose (SSD) and Provisioned IOPS (SSD) volumes have a throughput limit of 128 MB/s per volume.
  • CThere is a relationship between the maximum performance of your EBS volumes, the amount of I/O you are driving to them, and the amount of time it takes for each transaction to complete.
  • DThere is a 5 to 50 percent reduction in IOPS when you first access each block of data on a newly created or restored EBS volume.

  To serve Web traffic for a popular product your chief financial officer and IT director have purchased 10 ml large heavy utilization Reserved Instances (RIs) evenly spread across two Availability Zones. Route 53 is used to deliver the traffic to an Elastic Load Balancer (ELB). After several months, the product grows even more popular and you need additional capacity. As a result, your company purchases two C3.2xlarge medium utilization RIs. You register the two c3 2xlarge instances with your ELB and quickly find that the ml large instances are at 100% of capacity and the c3 2xlarge instances have significant capacity that's unused. Which option is the most cost effective and uses EC2 capacity most effectively?

  • AUse a separate ELB for each instance type and distribute load to ELBs with Route 53 weighted round robin.
  • BConfigure Autoscaling group and Launch Configuration with ELB to add up to 10 more on-demand ml large instances when triggered by Cloudwatch. Shut off c3 2xlarge instances.
  • CRoute traffic to EC2 ml large and c3 2xlarge instances directly using Route 53 latency based routing and health checks. Shut off ELB.
  • DConfigure ELB with two c3 2xlarge Instances and use on-demand Autoscaling group for up to two additional c3.2xlarge instances. Shut off m1.large instances.

  Can you encrypt EBS volumes?

  • AYes, you can enable encryption when you create a new EBS volume using the AWS Management Console, API, or CLI.
  • BNo, you should use a third-party software to perform raw block-level encryption of an EBS volume.
  • CYes, but you must use a third-party API for encrypting data before it's loaded on EBS.
  • DYes, you can encrypt with the special 'ebs_encrypt' command through Amazon APIs.

  You have deployed a three-tier web application in a VPC with a CIDR block of 10.0.0.0/28. You initially deploy two web servers, two application servers, two database servers and one NAT instance for a total of seven EC2 instances. The web, application and database servers are deployed across two Availability Zones (AZs). You also deploy an ELB in front of the two web servers, and use Route 53 for DNS. Web traffic gradually increases in the first few days following the deployment, so you attempt to double the number of instances in each tier of the application to handle the new load. Unfortunately some of these new instances fail to launch. Which of the following could be the root cause? (Choose 2 answers)

  • AAWS reserves the first and the last private IP address in each subnet's CIDR block so you do not have enough addresses left to launch all of the new EC2 instances.
  • BThe Internet Gateway (IGW) of your VPC has scaled-up, adding more instances to handle the traffic spike, reducing the number of available private IP addresses for new instance launches.
  • CThe ELB has scaled-up, adding more instances to handle the traffic spike, reducing the number of available private IP addresses for new instance launches.
  • DAWS reserves one IP address in each subnet's CIDR block for Route 53 so you do not have enough addresses left to launch all of the new EC2 instances.
  • EAWS reserves the first four and the last IP address in each subnet's CIDR block so you do not have enough addresses left to launch all of the new EC2 instances.
