AWS Cloud Practitioner

A retail company experiences significant traffic spikes during holiday seasons but minimal traffic during the rest of the year. Which benefit of the AWS Cloud BEST addresses this business need?

• AHigh availability across multiple data centers
• BElasticity to scale resources up and down based on demand
• CAccess to a broad set of global compliance certifications
• DAbility to deploy applications in multiple programming languages

A startup wants to launch a new application but cannot afford the upfront cost of purchasing physical servers. How does AWS Cloud computing help solve this problem?

• AAWS provides free servers for startups under 50 employees
• BAWS allows the company to trade upfront capital expense for variable operational expense
• CAWS guarantees lower total cost of ownership than any on-premises solution
• DAWS eliminates the need for any IT staff at the company

A company needs to deploy its application to serve customers in Asia, Europe, and North America with low latency. Which advantage of AWS Cloud computing makes this possible without building physical data centers in each region?

• AEconomies of scale
• BIncreased speed and agility
• CGlobal infrastructure with Regions and Availability Zones
• DManaged database services

Which scenario BEST demonstrates the agility benefit of cloud computing?

• AA company reduces its monthly IT spending by 15%
• BA development team provisions new test environments in minutes instead of weeks
• CAn application automatically recovers from a server failure
• DA company achieves SOC 2 compliance for its workloads

A company currently maintains its own data centers and wants to understand the total cost implications of cloud migration. Which factors should they consider when comparing on-premises costs to AWS Cloud costs?

• AOnly the monthly AWS service charges
• BHardware, power, cooling, staff salaries, and facility costs for on-premises versus pay-a…
• COnly the cost of EC2 instances needed to replace physical servers
• DThe cost of purchasing AWS data center equipment

A company currently pays $500,000 upfront every three years to refresh its server hardware. After migrating to AWS, it expects to pay $15,000 per month for equivalent compute resources. Which cloud economic principle does this transition represent?

• ABenefit from massive economies of scale
• BStop guessing capacity
• CTrade fixed expense for variable expense
• DIncrease speed and agility

How does AWS achieve lower pay-as-you-go prices for its customers compared to what most individual companies could achieve on their own?

• AAWS uses older, less expensive hardware
• BAWS aggregates usage from hundreds of thousands of customers to achieve economies of scale
• CAWS does not charge for data transfer
• DAWS receives government subsidies to reduce cloud pricing

A company provisioned 20 large EC2 instances for a new application but monitoring shows only 5 are needed during peak usage. Which cloud economics best practice should the company apply?

• APurchase Reserved Instances for all 20 servers to save money
• BRight-size the deployment by reducing to the appropriate number and size of instances
• CMove all instances to the largest available instance type for better performance
• DMigrate the workload back to on-premises data centers

Which statement BEST describes the difference between capital expenditure (CapEx) and operational expenditure (OpEx) in the context of cloud computing?

• ACapEx is a one-time expense for physical infrastructure; OpEx is an ongoing expense for s…
• BCapEx is always more expensive than OpEx
• COpEx requires long-term contracts while CapEx does not
• DCapEx refers to cloud costs while OpEx refers to on-premises costs

A company wants to reduce costs on EC2 instances that run a stable, predictable production workload 24/7. Which purchasing option would provide the GREATEST cost savings?

• AOn-Demand Instances
• BSpot Instances
• CReserved Instances or Savings Plans with a 3-year commitment
• DDedicated Hosts with no commitment

A solutions architect is designing an application that must continue operating even if an entire AWS data center experiences a failure. Which cloud design principle should they apply?

• ADesign for single-region deployment to reduce latency
• BDesign for failure by distributing workloads across multiple Availability Zones
• CDesign for cost optimization by using a single Availability Zone
• DDesign for simplicity by running everything on one large instance

Which cloud architecture principle recommends replacing a single large server with multiple smaller servers to handle a workload?

• AImplement elasticity
• BThink parallel — scale horizontally instead of vertically
• CAutomate everything
• DUse serverless architectures

A company wants to ensure its cloud infrastructure can be consistently and repeatedly deployed without manual configuration errors. Which cloud design principle addresses this need?

• AStop guessing capacity
• BTest at production scale
• CUse infrastructure as code (IaC) to automate deployments
• DGo global in minutes
