AWS Architecting and Ecosystem Flashcards
Auto Scaling in EC2 and DynamoDB are examples of?
a) Horizontal scaling
b) Vertical scaling
a) Horizontal scaling
Auto Scaling in EC2 allows you to have the right number of instances to handle the application load. Auto Scaling in DynamoDB automatically adjusts read and write throughput capacity, in response to dynamically changing request volumes, with zero downtime. These are both examples of horizontal scaling.
Which of the following are design principles of Performance Efficiency?
a) Go global in minutes and experiment more often
b) Analyze and attribute expenditure and stop spending money on data center operations
c) Make frequent small reversible changes and anticipate failure
d) Automate security best practices and keep away people from data
a) Go global in minutes and experiment more often
Performance Efficiency design principles include: democratize advanced technologies, go global in minutes, use serverless architecture, experiment more often, mechanical sympathy.
Which of the following is NOT an AWS Partner Network (APN) type?
a) APN Technology partners
b) APN Services partners
c) APN Consulting partners
d) APN Training partners
b) APN Services partners
This is a distractor. This type of AWS Partner Network does not exist. It is made up with words related to the AWS Partner Network.
Testing recovery procedures, stopping guessing capacity, and managing changes in automation are design principles of Performance Efficiency.
True or False
False
Testing recovery procedures, stopping guessing capacity, and managing changes in automation are design principles of Reliability. Performance Efficiency design principles include: democratize advanced technologies, go global in minutes, use serverless architecture, experiment more often, mechanical sympathy.
Which AWS service is the key to Operational Excellence?
a) CloudFormation
b) EC2
c) OpsWorks
d) CodeDeploy
a) CloudFormation
CloudFormation is a key service to Operational Excellence as it prepares, operates, and evolves, but also performs operations as code.
Which of the following options is NOT a vertical scaling limit?
a) Downtime
b) Higher cost
c) Capacity limitation
d) Better fault tolerance
d) Better fault tolerance
This is an advantage of horizontal scaling.
AWS Cost Explorer and AWS Trusted Advisor are services examples of which Well-Architected Framework pillar?
a) Security
b) Operational Excellence
c) Cost Optimization
d) Performance Efficiency
c) Cost Optimization
AWS Cost Explorer and AWS Trusted Advisor are Cost Optimization services examples. It also includes AWS Budgets, Cost and Usage Reports, etc.
Implementing Security Groups, NACLs, KMS, or CloudTrail reflects which Well-Architected Framework Pillar?
a) Reliability
b) Performance Efficiency
c) Security
d) Cost Optimization
c) Security
The Security pillar includes the ability to protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies.
What are the 5 pillars of the Well-Architected Framework?
- Operational Excellence
- Security
- Reliability
- Performance Efficiency
- Cost Optimization
What does the Operational Excellence pillar include?
The Operational Excellence pillar includes the ability to support the development and run workloads effectively, gain insight into the operation, and continuously improve supporting processes and procedures to deliver business value.
Design Principles
There are five design principles for operational excellence in the cloud:
Perform operations as code Make frequent, small, reversible changes Refine operations and procedures frequently Anticipate failure Learn from all operational failures
What does the Security pillar include?
The Security pillar includes the ability to protect data, systems, and assets to take advantage of cloud technologies to improve security.
Design Principles
There are seven design principles for security in the cloud:
Implement a strong identity foundation Enable traceability Apply security at all layers Automate security best practices Protect data in transit and at rest Keep people away from data Prepare for security events
What does the Reliability pillar include?
The Reliability pillar encompasses the ability of a workload to perform its intended function correctly and consistently when it’s expected to. This includes the ability to operate and test the workload through its total lifecycle.
Design Principles
There are five design principles for reliability in the cloud:
Automatically recover from failure Test recovery procedures Scale horizontally to increase aggregate workload availability Stop guessing capacity Manage change in automation
What does the Performance Efficiency pillar include?
The Performance Efficiency pillar includes the ability to use computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve.
Design Principles
There are five design principles for performance efficiency in the cloud:
Democratize advanced technologies Go global in minutes Use serverless architectures Experiment more often Consider mechanical sympathy
What does the Cost Optimization pillar include?
The Cost Optimization pillar includes the ability to run systems to deliver business value at the lowest price point.
Design Principles
There are five design principles for cost optimization in the cloud:
Implement cloud financial management Adopt a consumption model Measure overall efficiency Stop spending money on undifferentiated heavy lifting Analyze and attribute expenditure
