AWS 10 Cloud Journey

What is the advantage of the AWS-recommended practice of 'decoupling' applications?

• Allows treating an application as a single, cohesive unit.
• Reduces inter-dependencies so that failures do not impact other components of the application.
• Allows updates of any monolithic application quickly and easily.
• Allows tracking of any API call made to any AWS service.

One of the most important AWS best-practices to follow is the cloud architecture principle of elasticity. How does this principle improve your architecture's design?

• By automatically scaling your on-premises resources based on changes in demand.
• By automatically scaling your AWS resources using an Elastic Load Balancer.
• By reducing interdependencies between application components wherever possible.
• By automatically provisioning the required AWS resources based on changes in demand.

Which of the below is a best-practice when designing solutions on AWS?

• Invest heavily in architecting your environment, as it is not easy to change your design later.
• Use AWS reservations to reduce costs when testing your production environment.
• Automate wherever possible to make architectural (© ) experimentation easier.
• Provision a large compute capacity to handle any spikes in load

Which of the following is one of the benefits of moving infrastructure from an on-premises data center to AWS?

• Free support for all enterprise customers.
• Automatic data protection.
• Reduced Capital Expenditure (CapEx).
• AWS holds responsibility for managing customer applications.

Which statement best describes the operational excellence pillar of the AWS Well-Architected Framework?

• The ability of a system to recover gracefully from failure.
• The efficient use of computing resources to meet requirements.
• The ability to monitor systems and improve supporting processes and procedures.
• The ability to manage datacenter operations more efficiently.

Why would an organization decide to use AWS over an on-premises data center? (Choose TWO)

• Free commercial software licenses.
• Free technical support.
• Elastic resources.
• On-site visits for auditing.
• Cost Savings.

Which of the following activities supports the Operational Excellence pillar of the AWS Well-Architected Framework?

• Using AWS Trusted Advisor to find underutilized resources.
• Using AWS CloudTrail to record user activities.
• Using AWS CloudFormation to manage infrastructure as code.
• Deploying an application in multiple Availability Zones.

For new AWS customers, what is the EASIEST way to launch a simple WordPress website on AWS?

• Run WordPress on an Amazon Lightsail instance.
• Install WordPress on an Amazon EC2 instance.
• Use the Amazon S3 Web hosting feature.
• Host the website directly on AWS Cloud Development Kit (AWS CDK).

What are some key design principles for designing public cloud systems? (Choose TWO)

• Reserved capacity instead of on demand.
• Loose coupling over tight coupling.
• Servers instead of managed services.
• Disposable resources instead of fixed servers.
• Multi-AZ deployments instead of multi-region deployments.

Which of the following is a benefit of the 'Loose Coupling' architecture principle?

• It eliminates the need for change management.
• It allows for Cross-Region Replication.
• It helps AWS customers reduce Privileged Access to AWS resources.
• It allows individual application compenents or services to be modified without affecting other components.
