AWS solution architect interview questions and Answers
1. What is auto-scaling?
Auto-scaling is an AWS feature that allows you to set up and automatically offer and spin-up new instances without negotiating.
2. How will you get access to the data on EBS on AWS?
Elastic block storage provides permanent, highly available, and high-performance block-level storage that can join a running EC2 instance, as the name implies. The storage can be formatted and scaled as a file system or accessed as raw storage without any formatting.
When do you think you'd choose provided IOPS over RDS storage?
Provisioned IOPS requires batch-oriented workloads. Provisioned IOPS provides high IO rates, but they are also expensive. On the other hand, batch processing workloads do not necessitate manual involvement.
4. What is SimpleDB, and how does it work?
It's a well-structured data store that performs indexing and data searches for EC2 and S3.
5. What Is Amazon VPC, and Why Is It Used?
The most efficient approach to access your cloud services from your own data centre is through a virtual private cloud (VPC). Once you join your datacenter to the VPC, where you can install your instances, each instance is assigned a private IP address that you can access from your datacenter. In this method, you'll be able to connect to your public cloud services as if they were on your private network.
6. What happens if you launch the instances in an Amazon VPC?
If you start the instances in Amazon VPC, each occurrence will have a default IP address. You can evaluate this strategy when linking cloud resources to data centres.
7. Which of the following services can collect and process e-commerce data?
Amazon Redshift and Amazon DynamoDB are the best options. E-commerce website data is frequently in an unstructured format. Because they are both functional for unstructured data, we can use them both.
8. Is it feasible to transport things between data centres via direct connection?
Yes, it is possible. Because Cloud Front only accepts convention origins, you can finish this activity. Depending on the data transfer rates, you may be obliged to reimburse for it.
9. What is Amazon S3, and how does it work?
The most extensively used storage platform is Amazon S3, for Simple Storage Service. S3 is an object storage system that lets you store and retrieve any amount of data from any place. Despite its adaptability, it is practically limitless and cost-effective because of its on-demand storage. In addition to these advantages, it provides unrivalled durability and availability. Amazon S3 assists with data management for cost savings, access control, and compliance.
10. What is Amazon EC2? This state has several level instances, and how does it work?
Elastic Compute Cloud, or EC2, is a service that provides scalable computing power. Amazon EC2 eliminates the requirement for hardware purchases, allowing developers and administrators to design and deploy applications more quickly. Amazon EC2 allows you to create as many or as few virtual servers as you need and establish security and networking and manage storage. It may scale up or down in response to changing demand, which reduces traffic predictions. EC2 offers "instances," which are virtual computing environments.
11. Why is it necessary to construct subnets?
They must use a network with many hosts in a secure manner. The network may be more straightforward by dividing it into smaller subnets, and you can significantly reduce the likelihood of errors.
12. What exactly is AMI?
The AMI is a template for virtual computers. When starting a request, it may select pre-baked AMIs that AMI generally has in them. Not all AMIs, however, are available for free usage. Furthermore, you can use a modified AMI, and the most typical reason for doing so is to save space on Amazon Web Service.
13. How will you prepare an instance to serve traffic by configuring it with the application and its dependencies?
The use of lifecycle hooks can help you do this. They're useful because they let you pause the building or termination of an instance so you may peek inside and execute specific tasks like configuring the instance, downloading essential files, and executing any other tasks required to get it ready. There can be many lifecycle hooks in each auto-scaling group.
14. A distributed application runs across multiple EC2 servers and handles massive volumes of data. The application can gracefully recover from EC2 instance failures. How are you going to accomplish this on a budget?
Because the task is not continuous, an on-demand or reserved instance will not be appropriate. Moreover, because on-demand instances are expensive, launching one whenever work comes up does not make sense. Ainstances spot instance would be the best option in this circumstance due to its cost-effectiveness and lack of long-term obligations.
15.What does it mean when a connection drains?
Sometimes, the traffic must be re-verified for bugs' surplus files, which raises security problems. Connection draining aids in re-routing data from instances on a line to be more efficient.
16. A company wants to use AWS to deploy two-tier web applications. The application requires complex query processing and table joins. On the other hand, the corporation has limited resources and requires a high level of availability. What is the ideal configuration for a company to choose based on its needs?
DynamoDB addresses the essential issues of database scalability, management, stability, and performance; however, It doesn't have the skills of a relational database management system (RDBMS). DynamoDB does not support complicated joins, query processing, and complex transactions. You can use Amazon RDS or EC2 to operate a relational engine for this type of functionality.
17. What kind of architecture will you use if half of the workload is on the public cloud and the other half is on local storage?
Cloud Hybrid Architecture
18. What's the Difference Between Amazon Rds, Dynamodb, and Redshift?
Amazon RDS is a relational database management service provided by Amazon. Patching, upgrading, and data backups are all handled automatically. It's a database management service that only works with structured data. DynamoDB is a NoSQL database service for unstructured data. Redshift is a data warehouse and data analysis tool.
19. Is it possible to use EC2 instances to cast off S3?
Using root techniques backed by native occurrence storage, it is possible to cast-off S3 with EC2 instances.
20. What are the different states in processor state control?
There are two states in it: C- state: Its levels range from C0 to C6, with C6 being the mainframe's strongest state. P- state: This state has several levels, ranging from P0 to P15. P0 denotes the highest frequency, whereas P15 denotes the lowest frequency.
