NEW QUESTION # 168
A company's production application runs online transaction processing (OLTP) transactions on an Amazon RDS MySQL DB instance The company is launching a new reporting tool that will access the same data The reporting tool must be highly available and not impact the performance of the production application.
How can this be achieved?
- A. Create a Multi-AZ RDS Read Replica of the production RDS DB instance
- B. Create a Single-AZ RDS Read Replica of the production RDS DB instance Create a second Single-AZ RDS Read Replica from the replica
- C. Create multiple RDS Read Replicas of the production RDS DB instance Place the Read Replicas in an Auto Scaling group
- D. Create hourly snapshots of the production RDS DB instance
Answer: A
Explanation:
Explanation
Amazon RDS Read Replicas provide enhanced performance and durability for RDS database (DB) instances.
They make it easy to elastically scale out beyond the capacity constraints of a single DB instance for read-heavy database workloads. You can create one or more replicas of a given source DB Instance and serve high-volume application read traffic from multiple copies of your data, thereby increasing aggregate read throughput. Read replicas can also be promoted when needed to become standalone DB instances. Read replicas are available in Amazon RDS for MySQL, MariaDB, PostgreSQL, Oracle, and SQL Server as well as Amazon Aurora.
Amazon RDS Read Replicas Now Support Multi-AZ Deployments
Amazon RDS Read Replicas enable you to create one or more read-only copies of your database instance within the same AWS Region or in a different AWS Region. Updates made to the source database are then asynchronously copied to your Read Replicas. In addition to providing scalability for read-heavy workloads, Read Replicas can be promoted to become a standalone database instance when needed.
Amazon RDS Multi-AZ deployments provide enhanced availability for database instances within a single AWS Region. With Multi-AZ, your data is synchronously replicated to a standby in a different Availability Zone (AZ). In the event of an infrastructure failure, Amazon RDS performs an automatic failover to the standby, minimizing disruption to your applications.
You can now use Read Replicas with Multi-AZ as part of a disaster recovery (DR) strategy for your production databases. A well-designed and tested DR plan is critical for maintaining business continuity after a disaster. A Read Replica in a different region than the source database can be used as a standby database and promoted to become the new production database in case of a regional disruption.

While creating a network in the VPC, which of the following is true of a NAT device?
- A. You can choose to use any of the three kinds of NAT devices offered by AWS for special purposes.
- B. You have to administer the NAT Gateway Service provided by AWS.
- C. You are recommended to use AWS NAT instances over NAT gateways, as the instances provide better availability and bandwidth.
- D. You can use a NAT device to enable instances in a private subnet to connect to the Internet.
Answer: D
Explanation:
You can use a NAT device to enable instances in a private subnet to connect to the Internet (for example, for software updates) or other AWS services, but prevent the Internet from initiating connections with the instances. AWS offers two kinds of NAT devices u a NAT gateway or a NAT instance. We recommend NAT gateways, as they provide better availability and bandwidth over NAT instances. The NAT Gateway service is also a managed service that does not require your administration efforts. A NAT instance is launched from a NAT AMI. You can choose to use a NAT instance for special purposes.

NEW QUESTION # 176
In the most recent company meeting, your CEO focused on the fact that everyone in the organization needs to make sure that all of the infrastructure that is built is truly scalable. Which of the following statements is incorrect in reference to scalable architecture?
- A. Increasing resources results in a proportional increase in performance.
- B. A scalable service is capable of handling heterogeneity.
- C. A scalable architecture won't be cost effective as it grows.
- D. A scalable service is resilient.
Answer: C
Explanation:
In AWS it is critical to build a scalable architecture in order to take advantage of a scalable infrastructure.
The cloud is designed to provide conceptually infinite scalability. However, you cannot leverage all that scalability in infrastructure if your architecture is not scalable. Both have to work together. You will have to identify the monolithic components and bottlenecks in your architecture, identify the areas where you cannot leverage the on-demand provisioning capabilities in your architecture, and work to refactor your application, in order to leverage the scalable infrastructure and take advantage of the cloud.
Characteristics of a truly scalable application:
Increasing resources results in a proportional increase in performance
A scalable service is capable of handling heterogeneity
A scalable service is operationally efficient
A scalable service is resilient
A scalable service should become more cost effective when it grows (Cost per unit reduces as the number of units increases) Reference: http://media.amazonwebservices.com/AWS_Cloud_Best_Practices.pdf

NEW QUESTION # 181
You're running an application on-premises due to its dependency on non-x86 hardware and want to use AWS for data backup. Your backup application is only able to write to POSIX-compatible blockbased storage. You have 140TB of data and would like to mount it as a single folder on your file server Users must be able to access portions of this data while the backups are taking place. What backup solution would be most appropriate for this use case?
- A. Configure your backup software to use 53 as the target for your data backups.
- B. Use Storage Gateway and configure it to use Gateway Stored volumes.
- C. Configure your backup software to use Glacier as the target for your data backups.
- D. Use Storage Gateway and configure it to use Gateway Cached volumes.
Answer: D
Explanation:
Gateway-Cached Volume Architecture
Gateway-cached volumes let you use Amazon Simple Storage Service (Amazon 53) as your primary data storage while retaining frequently accessed data locally in your storage gateway. Gateway cached volumes minimize the need to scale your on-premises storage infrastructure, while still providing your applications with low-latency access to their frequently accessed data. You can create storage volumes up to 32 TIB in size and attach to them as iSCSI devices from your on-premises application servers. Your gateway stores data that you write to these volumes in Amazon 53 and retains recently read data in your on-premises storage gateway's cache and upload buffer storage.
Gateway-cached volumes can range from 1 GIB to 32 TIB in size and must be rounded to the nearest GIB.
Each gateway configured for gateway-cached volumes can support up to 32 volumes for a total maximum storage volume of 1,024 TIB (1 Pi B).
In the gateway-cached volume solution, AWS Storage Gateway stores all your on-premises application data in a storage volume in Amazon 53.
The following diagram provides an overview of the AWS Storage Gateway-cached volume deployment.
After you've installed the AWS Storage Gateway software appliance-the virtual machine (VM)-on a host in your data center and activated it, you can use the AWS Management Console to provision storage volumes backed by Amazon 53. You can also provision storage volumes programmatically using the AWS Storage Gateway API or the AWS SDK libraries. You then mount these storage volumes to your on-premises application servers as iSCSI devices.
You also al locate disks on-premises for the VM. These on-premises disks serve the following purposes:
Disks for use by the gateway as cache storage - As your applications write data to the storage volumes in AWS, the gateway initially stores the data on the on-premises disks referred to as cache storage before uploading the data to Amazon 53. The cache storage acts as the on-premises durable store for data that is waiting to upload to Amazon 53 from the upload buffer.
The cache storage also lets the gateway store your application's recently accessed data on-premises for low-latency access. If your application requests data, the gateway first checks the cache storage for the data before checking Amazon 53.
You can use the following guidelines to determine the amount of disk space to allocate for cache storage.
Generally, you should allocate at least 20 percent of your existing file store size as cache storage. Cache storage should also be larger than the upload buffer. This latter guideline helps ensure cache storage is large enough to persistently hold all data in the upload buffer that has not yet been uploaded to Amazon
5 3.
Disks for use by the gateway as the upload buffer - To prepare for upload to Amazon 53, your gateway also stores incoming data in a staging area, referred to as an upload buffer. Your gateway uploads this buffer data over an encrypted Secure Sockets Layer (SSL) connection to AWS, where it is stored encrypted in Amazon 53.
You can take incremental backups, called snapshots, of your storage volumes in Amazon 53. These point-in-time snapshots are also stored in Amazon 53 as Amazon EBS snapshots. When you take a new snapshot, only the data that has changed since your last snapshot is stored. You can initiate snapshots on a scheduled or one-time basis. When you delete a snapshot, only the data not needed for any other snapshots is removed.
You can restore an Amazon EBS snapshot to a gateway storage volume if you need to recover a backup of your data. Alternatively, for snapshots up to 16 TiB in size, you can use the snapshot as a starting point for a new Amazon EBS volume. You can then attach this new Amazon EBS volume to an Amazon EC2 instance.
All gateway-cached volume data and snapshot data is stored in Amazon 53 encrypted at rest using server-side encryption (SSE). However, you cannot access this data with the Amazon 53 API or other tools such as the Amazon 53 console.
