Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 43 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 43
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is using Amazon OpenSearch Service to analyze data. The company loads data into an OpenSearch Service cluster with 10 data nodes from an Amazon S3 bucket that uses S3 Standard storage. The data resides in the cluster for 1 month for read-only analysis. After 1 month, the company deletes the index that contains the data from the cluster. For compliance purposes, the company must retain a copy of all input data.

The company is concerned about ongoing costs and asks a solutions architect to recommend a new solution.

Which solution will meet these requirements MOST cost-effectively?

  • A. Replace all the data nodes with UltraWarm nodes to handle the expected capacity. Transition the input data from S3 Standard to S3 Glacier Deep Archive when the company loads the data into the cluster.
  • B. Reduce the number of data nodes in the cluster to 2 Add UltraWarm nodes to handle the expected capacity. Configure the indexes to transition to UltraWarm when OpenSearch Service ingests the data. Transition the input data to S3 Glacier Deep Archive after 1 month by using an S3 Lifecycle policy.
  • C. Reduce the number of data nodes in the cluster to 2. Add UltraWarm nodes to handle the expected capacity. Configure the indexes to transition to UltraWarm when OpenSearch Service ingests the data. Add cold storage nodes to the cluster Transition the indexes from UltraWarm to cold storage. Delete the input data from the S3 bucket after 1 month by using an S3 Lifecycle policy.
  • D. Reduce the number of data nodes in the cluster to 2. Add instance-backed data nodes to handle the expected capacity. Transition the input data from S3 Standard to S3 Glacier Deep Archive when the company loads the data into the cluster.

Selected Answer: B
B is the most cost-effective solution as it reduces the number of data nodes in the cluster to 2 and adds UltraWarm nodes to handle the expected capacity. By configuring the indexes to transition to UltraWarm when OpenSearch Service ingests the data, the company can take advantage of the lower storage costs of UltraWarm. Additionally, by transitioning the input data to S3 Glacier Deep Archive after 1 month using an S3 Lifecycle policy, the company can further reduce costs by using the lower storage costs of S3 Glacier Deep Archive for long-term data retention.

Option C can meet the requirements of reducing the number of data nodes in the cluster and using UltraWarm and cold storage nodes to handle the expected capacity and moving the data to lower cost storage after 1 month. However, it may not be the most cost-effective solution as it involves additional complexity in configuring the indexes to transition between different storage tiers, and may also require additional management and maintenance of the cold storage nodes. Option B, where the data is transitioned from S3 Standard to S3 Glacier Deep Archive using an S3 Lifecycle policy is simpler and more cost-effective as it eliminates the need for additional storage tiers and management.

Why can't I switch all nodes to ultrawarm. I can't find it anywhere in the documentation and it's not listed in the pre-requisites. Also why can the number of nodes be reduced from 10 to 2? is that because Ultrawarm use S3?

I need help here: To use UltraWarm storage, domains must have dedicated master nodes as per doc https://docs.aws.amazon.com/opensearch-service/latest/developerguide/ultrawarm.html The scenario mentions "an OpenSearch Service cluster with 10 data nodes". Assuming you only have these nodes in the cluster, in all answers you need to add dedicated master node(s). Assuming we also have dedicated master node why not replacing all data nodes with UltraWarm nodes?

I think I got it, UltraWarm is for read-only data. Thus you still need to have at least a data node

Option A says to replace all Data Nodes with ultra warm nodes. But this is NOT possible. There has to be atleast one data node

If you look at the IAM documentation here, you can see that the ec2:AuthorizeSecurityGroupIngress action doesn't have any conditions that would allow you to specify the ip addresses in the inbound/outbound rules.https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonec2.html

You can specify the IP address with the CIDR parameter https://ec2.amazonaws.com/?Action=AuthorizeSecurityGroupIngress &GroupId=sg-112233 &IpPermissions.1.IpProtocol=tcp &IpPermissions.1.FromPort=3389 &IpPermissions.1.ToPort=3389 &IpPermissions.1.IpRanges.1.CidrIp=192.0.2.0/24 &IpPermissions.1.IpRanges.1.Description=Access from New York office https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_AuthorizeSecurityGroupIngress.html

UltraWarm provides a cost-effective way to store large amounts of read-only data on Amazon OpenSearch Service. Standard data nodes use "hot" storage, which takes the form of instance stores or Amazon EBS volumes attached to each node. Hot storage provides the fastest possible performance for indexing and searching new data.

I asked ChatGPT. Can I use all UltraWarm nodes in AWS OpenSearch instead of data nodes? :) No, UltraWarm nodes in AWS OpenSearch are designed for storage and retrieval of infrequently accessed data, while data nodes are optimized for faster indexing and searching of data. While UltraWarm nodes can be used as a complement to data nodes, they are not a replacement for them.

Option B is the most cost-effective solution that meets the requirements. Reducing the number of data nodes in the cluster and adding UltraWarm nodes will help to reduce the ongoing costs of running the OpenSearch Service cluster. Configuring the indexes to transition to UltraWarm when OpenSearch Service ingests the data will further reduce costs. Additionally, transitioning the input data to S3 Glacier Deep Archive after 1 month by using an S3 Lifecycle policy will lower the storage costs of retaining the input data for compliance purposes.
