Q1. A newspaper organization has a on-premises application which allows the public to search Its back catalogue and retrieve individual newspaper pages via a website written in Jav a.
They have scanned the old newspapers into JPEGs (approx. 17TB) and used Optical Character Recognition (OCR) to populate a commercial search product. The hosting platform and software are now end of life and the organization wants to migrate its archive to AWS and produce a cost efficient architecture and still be designed for availability and durability. Which is the most appropriate?
A. Model the environment using CloudFormation, use an EC2 instance running Apache webserver and an open source search application, stripe multiple standard EBS volumes together to store the JPEGs and search index
B. Use a single-AZ RDS MySQL instance to store the search index and the JPEG Images, use an EC2 Instance to serve the website and translate user queries into SQL
C. Use a CloudFront download distribution to serve the JPEGs to the end users and install the current commercial search product, along with a Java Container for the website on EC2 instances and use Route53 with DNS round-robin
D. Use S3 with standard redundancy to store and serve the scanned files, use CloudSearch for query processing, and use Elastic Beanstalk to host the website across multiple availability zones
E. Use S3 with reduced redundancy to store and serve the scanned files, install the commercial search application on EC2 instances and configure with auto-scaling and an Elastic Load Balancer
Answer: A
Q2. A web company is looking to implement an intrusion detection and prevention system into their deployed VPC. This platform should have the ability to scale to thousands of instances running inside of the VPC. How should they architect their solution to achieve these goals?
A. Configure each host with an agent that collects all network traffic and sends that traffic to the IDS/IPS platform for inspection.
B. Configure an instance with monitoring software and the elastic network interface (ENI) set to promiscuous mode packet sniffing to see all traffic across the VPC.
C. Create a second VPC and route all traffic from the primary application VPC through the second VPC where the scalable virtualized IDS/IPS platform resides.
D. Configure servers running in the VPC using the host-based "route" commands to send all traffic through the platform to a scalable virtualized IDS/IPS.
Answer: D
Q3. Your company previously configured a heavily used, dynamically routed VPN connection between your on-premises data center and AWS.

After configuring DirectConnect settings in the AWS Console, which of the following options will provide the most seamless transition for your users?
A. Configure your DirectConnect router, update your VPC route tables to point to the DirectConnect connection, configure your VPN connection with a higher BGP priority, and verify network traffic is leveraging the DirectConnect connection.
B. Delete your existing VPN connection to avoid routing loops, configure your DirectConnect router with the appropriate settings, and verify network traffic is leveraging DirectConnect.
C. Update your VPC route tables to point to the DirectConnect connection, configure your DirectConnect router with the appropriate settings, verify network traffic is leveraging DirectConnect, and then delete the VPN connection.
D. Configure your DirectConnect router with a higher BGP priority than your VPN router, verify network traffic is leveraging DirectConnect, and then delete your existing VPN connection.
Answer: A
Q4. Your company runs a customer facing event registration site. This site is built with a 3-tier architecture with web and application tier servers and a MySQL database. The application requires 6 web tier servers and 6 application tier servers for normal operation, but can run on a minimum of 65% server capacity and a single MySQL database. When deploying this application in a region with three availability zones (AZs), which architecture provides high availability?
A. A web tier deployed across 2 AZs with 3 EC2 (Elastic Compute Cloud) instances in each A2 inside an Auto Scaling Group behind an ELB (elastic load balancer), and an application tier deployed across 2 AZs with 3 EC2 instances In each AZ inside an Auto Scaling Group behind an ELB, and one RDS (Relational Database Service) instance deployed with read replicas in the other AZ.
B. A web tier deployed across 3 AZs with 2 EC2 (Elastic Compute Cloud) instances in each AZ inside an Auto Scaling Group behind an ELB (elastic load balancer), and an application tier deployed across 3 AZs with 2 EC2 instances In each AZ inside an Auto Scaling Group behind an ELB, and a Multi-AZ RDS (Relational Database Service) deployment.
C. d. A web tier deployed across 2 AZs with 3 EC2 (Elastic Compute Cloud) instances in each AZ inside an Auto Scaling Group behind an ELB (elastic load balancer), and an application tier deployed across 2 AZs with 3 EC2 instances in each AZ inside an Auto Scaling Group behind an ELB, and a Multi-AZ RDS (Relational Database Service) deployment
D. A web tier deployed across 3 AZs with 2 EC2 (Elastic Compute Cloud) instances in each AZ inside an Auto Scaling Group behind an ELB (elastic load balancer), and an application tier deployed across 3 AZs with 2 EC2 instances in each AZ inside an Auto Scaling Group behind an ELB, and one RDS (Relational Database Service) instance deployed with read replicas in the two other AZs.
Answer: D
Q5. You require the ability to analyze a large amount of data which is stored on Amazon S3 using Amazon Elastic MapReduce. You are using the cc2.8xlarge instance type, whose CPUs are mostly idle during processing. Which of the below would be the most cost efficient way to reduce the runtime of the job?
A. Create fewer, larger files m Amazon S3.
B. Use smaller instances that have higher aggregate I/O performance.
C. Create more, smaller files on Amazon S3.
D. Add additional cc2.8xlarge instances by introducing a task group.
Answer: B
Q6. An AWS customer runs a public blogging website. The site users upload two million blog entries a month. The average blog entry size is 200 KB. The access rate to blog entries drops to negligible 6 months after publication and users rarely access a blog entry 1 year after publication. Additionally, blog entries have a high update rate during the first 3 months following publication, this drops to no updates after 6 months. The customer wants to use CloudFront to improve his user's load times. Which of the following recommendations would you make to the customer?
A. Duplicate entries into two different buckets and create two separate CloudFront distributions where S3 access is restricted only to CloudFront identity.
B. Create a CloudFront distribution with "US/Europe" price class for US/Europe users and a different CloudFront distribution with "All Edge Locations" for the remaining users.
C. Create a CloudFront distribution with Restrict Viewer Access, Forward Query String set to true and minimum TTL of 0.
D. Create a CloudFront distribution with S3 access restricted only to the CloudFront identity and partition the blog entry's location in S3 according to the month it was uploaded to be used with CloudFront behaviors.
Answer: D
Q7. To serve Web traffic for a popular product, your chief financial officer and IT director have purchased 10 m1.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 m1.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?
A. Configure Autoscaling group and Launch Configuration with ELB to add up to 10 more on- demand m1.large instances when triggered by Cloudwatch. Shut off c3.2xlarge instances.
B. Configure 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.
C. Route traffic to EC2 m1.large and c3.2xlarge instances directly using Route 53 latency based routing and health checks. Shut off ELB.
D. Use a separate ELB for each instance type and distribute load to ELBs with Route 53 weighted round robin.
