Amazon SAA-C03 Exam - Topic 1 Question 39 Discussion

Actual exam question for Amazon's SAA-C03 exam

Question #: 39
Topic #: 1

A company is deploying an application in three AWS Regions using an Application Load Balancer Amazon Route 53 will be used to distribute traffic between these Regions. Which Route 53 configuration should a solutions architect use to provide the MOST high-performing experience?

ACreate an A record with a latency policy.

BCreate an A record with a geolocation policy.

CCreate a CNAME record with a failover policy.

DCreate a CNAME record with a geoproximity policy.

Show Suggested Answer

Suggested Answer: B

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.

I’m surprised latency isn’t the default choice for this scenario!

CNAME with failover? Not sure that’s the best choice here.

I practiced a similar question about load balancing and I feel like latency policies were emphasized as the best choice for performance.

I'm not entirely sure, but I think geolocation policies might be better for targeting specific user demographics rather than performance.

I remember studying latency policies in Route 53, and I think they help direct users to the closest region based on response times.

I'm not sure if the failover policy is the right choice here. That's more for disaster recovery, not necessarily optimizing performance across Regions.

Okay, I've got this. The question is asking for the most high-performing experience, so I'm going to go with the latency policy. That should route traffic to the closest Region for the best performance.

Hmm, I'm a bit confused on the differences between the latency, geolocation, and geoproximity policies. I'll need to review those before deciding.

Ooh, this is a good one. The consultant will probably tell them to weigh the benefits of BYOD against the privacy risks. They'll need a comprehensive policy that protects the business while respecting employees' rights.

Okay, let's see. Partial encryption of a request, authentication of a request, and SAML token propagation - those sound like the key security schemes supported by OSB. I'll go with those three.

I don't know, maybe we should just flip a coin and call it a day. That's probably more accurate than these fancy routing policies, am I right?

You're all overthinking this. Option C is clearly the way to go - failover policy is the best for high availability, and CNAME records are more flexible than A records. Easy peasy!

Hold up, why not a CNAME record with a geoproximity policy? That way we can fine-tune the traffic distribution based on the user's location and proximity to the regions.
