질문 # 97
A company has a legal requirement to store point-in-time copies of its Amazon RDS PostGreSQL database instance in facilities that are at least 200 miles apart.
Use of which of the following provides the easiest way to comply with this requirement?

A. Cross-region read replica
B. Multiple Availability Zone read replica
C. Multiple Availability Zone snapshot copy
D. Cross-region snapshot copy

정답：D

설명：
Explanation
https://aws.amazon.com/blogs/aws/cross-region-snapshot-copy-for-amazon-rds/ You can enable point-in-time recovery using the AWS Management Console, AWS Command Line Interface (AWS CLI), or the DynamoDB API. When it's enabled, point-in-time recovery provides continuous backups until you explicitly turn it off.
After you enable point-in-time recovery, you can restore to any point in time within EarliestRestorableDateTime and LatestRestorableDateTime. LatestRestorableDateTime is typically 5 minutes before the current time.
Availability Zones:
With their own power infrastructure, the AZs are physically separated by a meaningful distance, many kilometers, from any other AZ, although all are within 100 km (60 miles of each other)

Large scale disaster recovery using AWS regions
DR takes things to a completely new level, wherein you need to be able to recover from a different region that's separated by over 250 miles

질문 # 98
You have a website which requires international presence and consequently you have set it up as follows.
It is hosted on 30 EC2 instances.
It is on in 15 regions around the globe. Each region has 2 instances.
All the instances are a public hosted zone.
Which of the following is the best way to configure your site to maintain availability with minimum downtime if one of the 15 regions was to lose network connectivity for an extended period? (Choose two.)

A. Create a Route 53 failover routing policy and configure an active-passive failover.
B. Create a Route 53 Latency Based Routing Record set that resolves to an Elastic Load Balancer in each region and has the Evaluate Target Health flag set to true.
C. Create a Route 53 Geolocation Routing Policy that resolves to an Elastic Load Balancer in each region and has the Evaluate Target Health flag set to false.
D. Create a Route 53 Failover Routing Policy and assign each resource record set a unique identifier and a relative weight.

정답：A,B

설명：
It is best to use the latency routing policy when you have resources in multiple Amazon EC2 data centers that perform the same function and you want Amazon Route 53 to respond to DNS queries with the resources that provide the best latency. You could also use the failover routing policy (for public hosted zones only) when you want to configure an active-passive failover, in which one resource takes all traffic when it's available and the other resource takes all traffic when the first resource isn't available.

질문 # 99
A gaming company is using Amazon DynamoDB to run a high-score leaderboard and record the game progress for users The company is launching a new game that is expected to be active for years The database activity at launch cannot be predicted; but it is expected to stabilize after 4 weeks Currently, the company is using on-demand capacity mode for processing reads and writes on all DynamoDB tables.
What is the MOST cost-effective way for the company to control the DynamoDB capacity during the new game launch?

A. Use on-demand mode and purchase DynamoDB reserved capacity for the first 4 weeks of the game launch
B. Use provisioned capacity mode, and purchase DynamoDB reserved capacity for the first 4 weeks of the game launch
C. Use on-demand mode for the game launch, switch to provisioned capacity mode after 4 weeks and then purchase DynamoDB reserved capacity
D. Use provisioned capacity mode for the game launch, switch back to on-demand mode after 4 weeks, and then purchase DynamoDB reserved capacity

정답：C

질문 # 100
You have set up an S3 bucket with a number of images in it and you have decided that you want anybody to be able to access these images, even anonymous users. To accomplish this you create a bucket policy.
You will need to use an Amazon S3 bucket policy that specifies a __________ in the principal element, which means anyone can access the bucket.

A. S3 user
B. hash tag (#)
C. wildcard (*)
D. anonymous user

정답：C

설명：
You can use the AWS Policy Generator to create a bucket policy for your Amazon S3 bucket. You can then use the generated document to set your bucket policy by using the Amazon S3 console, by a number of third-party tools, or via your application.
You use an Amazon S3 bucket policy that specifies a wildcard (*) in the principal element, which means anyone can access the bucket. With anonymous access, anyone (including users without an AWS account) will be able to access the bucket.

질문 # 101
Asocial media company has workloads that collect and process data The workloads store the data in on-premises NFS storage The data store cannot scale fast enough to meet the company's expanding business needs The company wants to migrate the current data store to AWS Which solution will meet these requirements MOST cost-effectively?

A. Set up an AWS Storage Gateway Amazon S3 File Gateway Use an Amazon S3 Lifecycle policy to transition the data to the appropriate storage class
B. Set up an AWS Storage Gateway Volume Gateway Use an Amazon S3 Lifecycle policy to transition the data to the appropnate storage class
C. Use the Amazon Elastic File System (Amazon EFS) Standard-Infrequent Access (Standard-IA) storage class Activate the infrequent access lifecycle policy
D. Use the Amazon Elastic File System (Amazon EFS) One Zone-Infrequent Access (One Zone-IA) storage class Activate the infrequent access lifecycle policy

정답：A

설명：
This solution meets the requirements most cost-effectively because it enables the company to migrate its on-premises NFS data store to AWS without changing the existing applications or workflows. AWS Storage Gateway is a hybrid cloud storage service that provides seamless and secure integration between on-premises and AWS storage. Amazon S3 File Gateway is a type of AWS Storage Gateway that provides a file interface to Amazon S3, with local caching for low-latency access. By setting up an Amazon S3 File Gateway, the company can store and retrieve files as objects in Amazon S3 using standard file protocols such as NFS. The company can also use an Amazon S3 Lifecycle policy to automatically transition the data to the appropriate storage class based on the frequency of access and the cost of storage. For example, the company can use S3 Standard for frequently accessed data, S3 Standard-Infrequent Access (S3 Standard-IA) or S3 One Zone-Infrequent Access (S3 One Zone-IA) for less frequently accessed data, and S3 Glacier or S3 Glacier Deep Archive for long-term archival data.
Option A is not a valid solution because AWS Storage Gateway Volume Gateway is a type of AWS Storage Gateway that provides a block interface to Amazon S3, with local caching for low-latency access. Volume Gateway is not suitable for migrating an NFS data store, as it requires attaching the volumes to EC2 instances or on-premises servers using the iSCSI protocol. Option C is not a valid solution because Amazon Elastic File System (Amazon EFS) is a fully managed elastic NFS file system that is designed for workloads that require high availability, scalability, and performance. Amazon EFS Standard-Infrequent Access (Standard-IA) is a storage class within Amazon EFS that is optimized for infrequently accessed files, with a lower price per GB and a higher price per access. Using Amazon EFS Standard-IA for migrating an NFS data store would not be cost-effective, as it would incur higher access charges and require additional configuration to enable lifecycle management. Option D is not a valid solution because Amazon EFS One Zone-Infrequent Access (One Zone-IA) is a storage class within Amazon EFS that is optimized for infrequently accessed files that do not require the availability and durability of Amazon EFS Standard or Standard-IA. Amazon EFS One Zone-IA stores data in a single Availability Zone, which reduces the cost by 47% compared to Amazon EFS Standard-IA, but also increases the risk of data loss in the event of an Availability Zone failure. Using Amazon EFS One Zone-IA for migrating an NFS data store would not be cost-effective, as it would incur higher access charges and require additional configuration to enable lifecycle management. It would also compromise the availability and durability of the data.
