The AWS Well-Architected Tool provides a plan on how to architect for the cloud using established best practices.
The AWS Well-Architected Tool helps cloud architects review and improve their workloads based on AWS best practices across the six pillars of the Well-Architected Framework.
___________focuses on achieving the lowest price for a system/workload. Optimize the cost while considering the account needs without ignoring factors like security, reliability, and performance.
Cost Optimization is the Well-Architected pillar focused on achieving the lowest cost while maintaining appropriate security, reliability, and performance for a workload.
A pillar focuses on ensuring a system/workload delivers maximum performance for a set of AWS resources utilized.
Performance Efficiency ensures IT and computing resources efficiently meet system requirements. It covers selecting the right resource types and sizes and monitoring performance.
____________ is a small, rugged, and secure edge computing and data transfer device.
AWS Snowcone is the smallest, most portable member of the AWS Snow Family — a ruggedized edge computing and data transfer device weighing just 4.5 lbs.
AWS WAF tool is used for reviewing existing infrastructure.
FALSE — AWS WAF (Web Application Firewall) protects web applications from common exploits like SQL injection. The AWS Well-Architected Tool is used for reviewing infrastructure architecture.
Which of the following database services support dynamic schema?
Amazon DynamoDB is a NoSQL database with a flexible, schemaless design. Each item in a DynamoDB table can have different attributes, unlike relational databases that require a fixed schema.
Cloudwatch can monitor custom metrics in-addition to built-in metrics.
Amazon CloudWatch monitors AWS resources and applications. It collects built-in AWS service metrics and also allows publishing custom metrics from your own applications.
AutoScaling increases/decreases the capacity of an EC2 instance automatically.(True/False)
AWS Auto Scaling automatically adjusts EC2 capacity up or down in response to defined conditions, ensuring optimal performance and cost efficiency.
AWS DynamoDB is a serverless nosql database
Amazon DynamoDB is a fully managed, serverless NoSQL database that supports a flexible, schemaless data model — each item can have different attributes.
Which of the following database service is PostgreSQL and MySQL compatible?
Amazon Aurora is a cloud-native relational database fully compatible with MySQL and PostgreSQL, offering up to 5x MySQL and 3x PostgreSQL performance at a lower cost.
Amazon EC2 ________ allow you to request spare Amazon EC2 computing capacity for up to 90 percent off the On-Demand price.
Amazon EC2 Spot Instances let you use spare AWS compute capacity at up to 90% discount compared to On-Demand prices, ideal for fault-tolerant batch and stateless workloads.
Which of the pricing options do customers pay per hour for compute?
On-Demand pricing charges by the hour (or per second for some instance types) with no upfront commitment, providing maximum flexibility for variable or unpredictable workloads.
Cost varies between regions(True/False)
The correct answer is: True.
In AWS, you need to buy servers to host application.(True/False)
FALSE — In AWS, you do not need to buy physical servers. AWS provides virtual compute resources on demand, eliminating upfront hardware purchases.
Cloud computing converts capital expenditure into operational expenditure by:
Cloud computing converts upfront capital expenditure (CapEx) — buying servers — into operational expenditure (OpEx) by paying only for the resources consumed.
Which of the following is NOT one of the six advantages mentioned for cloud computing?
The six advantages of cloud computing include: Trade CapEx for OpEx, benefit from massive economies of scale, stop guessing capacity, increase speed and agility, stop spending on data centers, and go global in minutes.
On-premise data centers compared to cloud generally have:
On-premises data centers require high upfront capital investment in hardware and facilities, in contrast to cloud's pay-as-you-go model.
Which service model provides virtual servers, storage and networking while you manage the OS?
The correct answer is: IaaS.
Which cloud deployment model mixes on-premises and cloud resources?
On-premises data centers require high upfront capital investment in hardware and facilities, in contrast to cloud's pay-as-you-go model.
AWS launched its cloud services in which year?
The correct answer is: 2006.
