Q73. You have been asked to design the storage layer for an application. The application requires disk
performance of at least 100,000 IOPS in addition, the storage layer must be able to survive the loss of an indMdual disk. EC2 instance, or Availability Zone without any data loss. The volume you provide must have a capacity of at least 3 TB. Which of the following designs will meet these objectives'?
A. Instantiate a c3.8x|arge instance in us-east-1. Provision 4x1TB EBS volumes, attach them to the instance, and configure them as a single RAID 5 volume. Ensure that EBS snapshots are performed every 15 minutes.
B. Instantiate a c3.8xIarge instance in us-east-1. Provision 3xiTB EBS volumes, attach them to the Instance, and configure them as a single RAID 0 volume. Ensure that EBS snapshots are performed every 15 minutes.
C. Instantiate an i2.8xIarge instance in us-east-Ia. Create a RAID 0 volume using the four 800GB SSD ephemeral disks provided with the instance. Provision 3x1TB EBS volumes, attach them to the instance, and configure them as a second RAID 0 volume. Configure synchronous, block-level replication from the ephemeral-backed volume to the EBS-backed volume.
D. Instantiate a c3.8xIarge instance in us-east-1. Provision an AWS Storage Gateway and configure it for 3 TB of storage and 100,000 IOPS. Attach the volume to the instance. E. Instantiate an i2.8x|arge instance in us-east-Ia. Create a RAID 0 volume using the four 800GB SSD ephemeral disks provided with the instance. Configure synchronous, block- level replication to an identically configured instance in
us-east-Ib.

A. Route 53 offers low query latency for your end users.
B. Route 53 is designed to automatically answer queries from the optimal location depending on network conditions.
C. The globally distributed nature of AWS's DNS servers helps ensure a consistent ability to route your end users to your application.
D. Route 53 supports Domain Name System Security Extensions (DNSSEC).
Answer: D
Explanation:
Amazon Route 53 provides highly available and scalable Domain Name System (DNS), domain name registration, and health-checking web services.
Route 53 is built using AWS’s highly available and reliable infrastructure. The globally distributed nature of our DNS servers helps ensure a consistent ability to route your end users to your application by circumventing any internet or network related issues. Route 53 is designed to provide the level of dependability required by important applications. Using a global anycast network of DNS servers around the world, Route 53 is designed to automatically answer queries from the optimal location depending on network conditions. As a result, the service offers low query latency for your end users.
Amazon Route 53 does not support Domain Name System Security Extensions (DNSSEC) at this time. Reference: https://aws.amazon.com/route53/faqs/
Q75. You are looking at ways to improve some existing infrastructure as it seems a lot of engineering resources are being taken up with basic management and monitoring tasks and the costs seem to be excessive.
You are thinking of deploying Amazon E|asticCache to help. Which of the following statements is true in regards to EIasticCache?
A. You can improve load and response times to user actions and queries however the cost associated with scaling web applications will be more.
B. You can't improve load and response times to user actions and queries but you can reduce the cost associated with scaling web applications.
C. You can improve load and response times to user actions and queries however the cost associated with scaling web applications will remain the same.
D. You can improve load and response times to user actions and queries and also reduce the cost associated with scaling web applications.
Answer: D
Explanation:
Amazon EIastiCache is a web service that makes it easy to deploy and run Memcached or Redis protocol-compliant server nodes in the cloud. Amazon EIastiCache improves the performance of web applications by allowing you to retrieve information from a fast, managed, in-memory caching system, instead of relying entirely on slower disk-based databases. The service simplifies and offloads the management, monitoring and operation of in-memory cache environments, enabling your engineering resources to focus on developing applications.
Using Amazon EIastiCache, you can not only improve load and response times to user actions and queries, but also reduce the cost associated with scaling web applications.
