NEW QUESTION 63
A company needs to move its on-premises resources to AWS. The current environment consists of 100 virtual machines (VMs) with a total of 40 TB of storage. Most of the VMs can be taken offline because they support functions during business hours only; however, some are mission critical, so downtime must be minimized.
The administrator of the on-premises network provisioned 10 Mbps of internet bandwidth for the migration. The on-premises network throughput has reached capacity and would be costly to increase. A solutions architect must design a migration solution that can be performed within the next 3 months.
Which method would fulfill these requirements?
- A. Use AWS Application Discovery Service to assess each application, and determine how to refactor and optimize each using AWS services or AWS Marketplace solutions.
- B. Set up a 1Gbps AWS Direct Connect connection. Then provision a private virtual interface, and use AWS Server Migration Service (SMS) to migrate the VMs into Amazon EC2.
- C. Migrate mission-critical VMs with AWS SMS. Export the other VMs locally and transfer them to Amazon S3 using AWS Snowball. Use VM Import/Export to import the VMs into Amazon EC2.
- D. Export the VMs locally, beginning with the most mission-critical servers first. Use AWS Transfer for SFTP to securely upload each VM to Amazon S3 after they are exported. Use VM Import/Export to import the VMs
Answer: C
NEW QUESTION 64
You are implementing a URL whitelisting system for a company that wants to restrict outbound HTTP'S connections to specific domains from their EC2-hosted applications. You deploy a single EC2 instance running proxy software and configure It to accept traffic from all subnets and EC2 instances in the VPC. You configure the proxy to only pass through traffic to domains that you define in its whitelist configuration. You have a nightly maintenance window or 10 minutes where all instances fetch new software updates. Each update Is about 200MB In size and there are 500 instances In the VPC that routinely fetch updates. After a few days you notice that some machines are failing to successfully download some, but not all of their updates within the maintenance window. The download URLs used for these updates are correctly listed in the proxy's whitelist configuration and you are able to access them manually using a web browser on the instances.
What might be happening? (Choose 2)
- A. You are running the proxy on a sufficiently-sized EC2 instance in a private subnet and its network throughput is being throttled by a NAT running on an undersized EC2 instance.
- B. You have not allocated enough storage to the EC2 instance running the proxy so the network buffer is filling up, causing some requests to fail.
- C. You are running the proxy in a public subnet but have not allocated enough EIPs to support the needed network throughput through the Internet Gateway (IGW).
- D. You are running the proxy on an undersized EC2 instance type so network throughput is not sufficient for all instances to download their updates in time.
- E. The route table for the subnets containing the affected EC2 instances is not configured to direct network traffic for the software update locations to the proxy.
Answer: A,D

NEW QUESTION 68
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 tor 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 Route53 for DNS Web (raffle 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 caused? (Choose 2 answers)
- A. AWS 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
- B. AWS reserves one IP address in each subnet's CIDR block for Route53 so you do not have enough addresses left to launch all of the new EC2 instances
- C. AWS 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
- D. The 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
- E. The ELB has scaled-up, adding more instances to handle the traffic spike, reducing the number of available private IP addresses for new instance launches

NEW QUESTION 72
An Auto Scaling group is running at the desired capacity of 5 instances and receives a trigger from the Cloudwatch Alarm to increase the capacity by 1. The cool down period is 5 minutes.
Cloudwatch sends another trigger after 2 minutes to decrease the desired capacity by 1. What will be the count of instances at the end of 4 minutes?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
The cool down period is the time difference between the end of one scaling activity (can be start or terminate) and the start of another one (can be start or terminate). During the cool down period, Auto Scaling does not allow the desired capacity of the Auto Scaling group to be changed by any other CloudWatch alarm. Thus, in this case the trigger from the second alarm will have no effect.

NEW QUESTION 73
In the context of AWS Cloud Hardware Security Module(HSM), does your application need to reside in the same VPC as the CloudHSM instance?
- A. No, but they must reside in the same Availability Zone.
- B. No, but the server or instance on which your application and the HSM client is running must have network (IP) reachability to the HSM.
- C. Yes, always
- D. No, but it should reside in same Availability Zone as the DB instance.
Answer: B
Explanation:
Your application does not need to reside in the same VPC as the CloudHSM instance. However, the server or instance on which your application and the HSM client is running must have network (IP) reachability to the HSM. You can establish network connectivity in a variety of ways, including operating your application in the same VPC, with VPC peering, with a VPN connection, or with Direct Connect.

A user has configured EBS volume with PIOPS. The user is not experiencing the optimal throughput. Which of the following could not be factor affecting I/O performance of that EBS volume?
- A. EBS bandwidth of dedicated instance exceeding the PIOPS
- B. EC2 bandwidth
- C. EBS volume size
- D. Instance type is not EBS optimized
