AWS-Solutions-Architect-Professional PDF DEMO:
QUESTION NO: 1 A company runs a legacy system on a single m4.2xlarge Amazon EC2 instance with Amazon EBS2 storage. The EC2 instance runs both the web server and a self-managed Oracle database. A snapshot is made of the EBS volume every 12 hours, and an AMI was created from the fully configured EC2 instance. A recent event that terminated the EC2 instance led to several hours of downtime. The application was successfully launched from the AMI, but the age of the EBS snapshot and the repair of the database resulted in the loss of 8 hours of data. The system was also down for 4 hours while the Systems Operators manually performed these processes. What architectural changes will minimize downtime and reduce the chance of lost data? A. Create an Amazon CloudWatch alarm to automatically recover the instance. Create a script that will check and repair the database upon reboot. Subscribe the Operations team to the Amazon SNS message generated by the CloudWatch alarm. B. Increase the web server instance count to two m4.xlarge instances and use Amazon Route 53 round-robin load balancing to spread the load. Enable Route 53 health checks on the web servers. Migrate the database to an Amazon RDS Oracle Multi-AZ DB instance. C. Run the application on m4.xlarge EC2 instances behind an Elastic Load Balancer/Application Load Balancer. Run the EC2 instances in an Auto Scaling group across multiple Availability Zones with a minimum instance count of two. Migrate the database to an Amazon RDS Oracle Multi-AZ DB instance. D. Run the application on m4.2xlarge EC2 instances behind an Elastic Load Balancer/Application Load Balancer. Run the EC2 instances in an Auto Scaling group access multiple Availability Zones with a minimum instance count of one. Migrate the database to an Amazon RDS Oracle Multi-AZ DB instance. Answer: C
QUESTION NO: 2 You want to establish redundant VPN connections and customer gateways on your network by setting up a second VPN connection. Which of the following will ensure that this functions correctly? A. The customer gateway IP address for the second VPN connection must use dynamic routes. B. The customer gateway IP address for the second VPN connection must be privately accessible and be the same public IP address that you are using for the first VPN connection. C. The customer gateway IP address for the second VPN connection must be publicly accessible. D. The virtual gateway IP address for the second VPN connection must be publicly accessible. Answer: C Explanation: To establish redundant VPN connections and customer gateways on your network, you would need to set up a second VPN connection. However, you must ensure that the customer gateway IP address for the second VPN connection is publicly accessible. http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html
QUESTION NO: 3 An organization is planning to setup a management network on the AWS VPC. The organization is trying to secure the webserver on a single VPC instance such that it allows the internet traffic as well as the back-end management traffic. The organization wants to make so that the back end management network interface can receive the SSH traffic only from a selected IP range, while the internet facing webserver will have an IP address which can receive traffic from all the internet IPs. How can the organization achieve this by running web server on a single instance? A. The organization should launch an instance with two separate subnets using the same network interface which allows to have a separate CIDR as well as security groups. B. The organization should create two network interfaces with the same subnet and security group to assign separate IPs to each network interface. C. The organization should create two network interfaces with separate subnets so one instance can have two subnets and the respective security groups for controlled access. D. It is not possible to have two IP addresses for a single instance. Answer: C Explanation: A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the user to launch AWS resources into a virtual network that the user has defined. An Elastic Network Interface (ENI) is a virtual network interface that the user can attach to an instance in a VPC. The user can create a management network using two separate network interfaces. For the present scenario it is required that the secondary network interface on the instance handles the public facing traffic and the primary network interface handles the back-end management traffic and it is connected to a separate subnet in the VPC that has more restrictive access controls. The public facing interface, which may or may not be behind a load balancer, has an associated security group to allow access to the server from the internet while the private facing interface has an associated security group allowing SSH access only from an allowed range of IP addresses either within the VPC or from the internet, a private subnet within the VPC or a virtual private gateway. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html
QUESTION NO: 4 A company is currently running a production workload on AWS that is very I/O intensive. Its workload consists of a single tier with 10 c4.8xlarge instances, each with 2 TB gp2 volumes. The number of processing jobs has recently increased, and latency has increased as well. The team realizes that they are constrained on the IOPS. For the application to perform efficiently, they need to increase the IOPS by 3,000 for each of the instances. Which of the following designs will meet the performance goal MOST cost effectively? A. Change the type of Amazon EBS volume from gp2 to io1 and set provisioned IOPS to 9,000. B. Create a new Amazon S3 bucket and move all the data to this new bucket. Allow each instance to access this S3 bucket and use it for storage. C. Create a new Amazon EFS file system and move all the data to this new file system. Mount this file system to all 10 instances. D. Increase the size of the gp2 volumes in each instance to 3 T Answer: D Explanation: A: IO1 or provisioned IOPS SSD is more expensive. B: GP1 with 2TB volumes has 6000 IOPS. If we add additional 1TB it will increase by another 3000 IOPS. Note: Bursting and I/O credits are only relevant to volumes under 1,000 GiB, where burst performance exceeds baseline performance. C\D: Not enough information is actually provided for us so we don't know if the instance can use shared storage or not.
QUESTION NO: 5 An organization is setting a website on the AWS VPC. The organization has blocked a few IPs to avoid a D-DOS attack. How can the organization configure that a request from the above mentioned IPs does not access the application instances? A. Configure an ACL at the subnet which denies the traffic from that IP address. B. Create an IAM policy for VPC which has a condition to disallow traffic from that IP address. C. Configure a security group at the subnet level which denies traffic from the selected IP. D. Configure the security group with the EC2 instance which denies access from that IP address. Answer: A Explanation: A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the user to launch AWS resources into a virtual network that the user has defined. AWS provides two features that the user can use to increase security in VPC: security groups and network ACLs. Security group works at the instance level while ACL works at the subnet level. ACL allows both allow and deny rules. Thus, when the user wants to reject traffic from the selected IPs it is recommended to use ACL with subnets. http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_ACLs.html
