Your first job is to launch 10 Large EC2 instances which will all be used to crunch huge amounts of data and will also need to pass this data back and forth between each other. Which of the following would be the most efficient setup to achieve this?

Which of the below mentioned protocols the user can configure for Elastic load Balancer health checks while setting up Elastic load Balancer? SSL HTTPS TCP All of the options 10 / 20 You’re working as a constant for a company designing a new hybrid architecture to manage part of their application infrastructure in the cloud and on-premise. As part of the infrastructure, they need to consistently transfer high amounts of data. They require a low latency and high consistency traffic to AWS. The company is looking to keep costs as low possible and is willing to accept slow traffic in the event of primary failure. Given these requirements how would you design a hybrid architecture? Provision a Direct Connect connection to an AWS region using a Direct Connect provider. Provision a secondary Direct Connect connection as a failover. Provision a Direct Connect connection which has automatic failover and backup built into the service. Create a dual VPN tunnel for private connectivity, which increases network consistency and reduces latency. The dual tunnel provides a backup VPN in the case of primary failover. Provision a Direct Connect connection to an AWS region using a Direct Connect partner. Provision a VPN connection as a backup in the event of Direct Connect connection failure. 11 / 20 You’re working as a consultant for a big multinational company that has a three tier application. The application layer of this architecture sends over 20Gbps of data per seconds during peak hours to and from Amazon S3. Currently, you’re running two NAT gateways in two subnets to transfer the data from your private application layer to Amazon S3. You will also need to ensure that the instances receive software patches from a third party repository. What architecture changes should be made, if any? NAT gateways support 10Gbps and two are running: Add a third to a third subnet to allow for any increase in demand. NAT gateways support 10Gbps and two are running: No changes are required to improve this architecture Keep the NAT gateway and create a VPC S3 endpoint which allows for higher bandwidth throughput as well as tighter security. Remove the NAT gateway and create a VPC S3 endpoint which allows for higher bandwidth throughput as well as tighter security. 12 / 20 One of your developer has attached an EBS volume to a Linux instance (which is running) as a “ /dev/sdf ” device. He comes back to you saying he is unable to see the attached device when he runs the command “df -h”. What is the possible reason do you think for this? The volume is not formatted The volume is not in the same AZ of the instance The volume is not attached as a root device The volume has not been mounted 13 / 20 In DynamoDB, to get a detailed listing of secondary indexes on a table, you can use which of the below action? BatchGetItem DescribeTable TableName GetItem 14 / 20 In relation to Amazon Simple Workflow Service (Amazon SWF),what is an “Activity Worker”?

Use the largest EC2 instances currently available on AWS, but make sure they are all in the same region Use the largest EC2 instances currently available on AWS, but make sure they are all in the same Availability Zone Use Placement Groups and launch the 10 instances at the same time. Use Placement Groups. Make sure the 10 Instances are spread evenly across Availability Zones. 16 / 20 Complete this statement: “When you load your table directly from an Amazon ___________ table, you have the option to control the amount of provisioned throughput you consume.” DynamoDB S3 RDS DataPipeline 17 / 20 Can a user get a notification of each instance start / terminate configured with Auto Scaling?

Do you think he can access it? No Yes, but only if you have direct connect or vpn Only if you are using a US region Only if you are using a non-US region 20 / 20 Your tech lead has set an IAM policy where it allows all requests if a request from IP 10.11.11.1/32.
