Which of the following tasks can be accomplished using the AWS Pricing Calculator to meet these requirements? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: Estimate the monthly operational costs of the serverless architecture by inputting hypothetical usage metrics, such as estimated Lambda invocations and DynamoDB read/write capacity units.; Evaluate the cost difference between different pricing models, such as choosing On-Demand versus Provisioned Capacity with commitments for DynamoDB.

Answer

The team can estimate the monthly operational costs by inputting hypothetical usage metrics (such as Lambda invocations and DynamoDB capacity units) and evaluate the cost difference between different pricing models (such as On-Demand versus Provisioned Capacity).
The AWS Pricing Calculator is designed for estimating future cloud costs based on hypothetical parameters. It allows users to estimate monthly costs by inputting expected usage metrics (like Lambda invocation numbers or database capacity units) and compare various pricing structures (such as On-Demand versus Provisioned Capacity) to identify the most cost-effective strategy before launching the workloads.

Step-by-Step Solution

1
Determine the phase of the resource lifecycle described in the scenario.
The workload is in the pre-deployment phase, meaning no AWS resources have been provisioned yet.
Cost estimation needs differ depending on whether the workload is active or hypothetical.
2
Identify the tools capable of modeling hypothetical configurations.
The AWS Pricing Calculator is the correct tool for estimating costs based on hypothetical resource shapes and usage details.
It allows entering planned configuration metrics like Lambda execution counts and DynamoDB capacity to generate an estimate.
3
Evaluate pricing model comparisons within the planning tool.
The AWS Pricing Calculator allows comparing On-Demand versus commitment-based pricing options to find the most cost-effective approach.
This directly fulfills the requirement to compare various pricing options before provisioning.
4
Eliminate post-deployment monitoring and reporting tools.
AWS Budgets and the AWS Cost & Usage Report are excluded because they rely on actual post-deployment tracking and billing logs.
These tools cannot model hypothetical resources or ingest on-premises logs to generate pricing estimates.

Question 1322Question

A small business is reviewing its AWS bill after operating its infrastructure on a single AWS account for 1414 months. The business regularly utilizes several AWS services, keeping their monthly usage low. Which of the following resource configurations will continue to be covered under the AWS Free Tier?

Show answer & explanation

Answer: A configuration consisting of 15 GB15\text{ GB} of Amazon DynamoDB storage and 500000500{}000 AWS Lambda requests per month

Answer

A configuration consisting of 15 GB15\text{ GB} of Amazon DynamoDB storage and 500000500{}000 AWS Lambda requests per month
The configuration containing Amazon DynamoDB and AWS Lambda requests is correct because both of these service allocations fall under the 'Always Free' category. They do not expire after 12 months, and the requested amounts (15 GB15\text{ GB} and 500000500{}000 requests) remain under the monthly free limits of 25 GB25\text{ GB} and 1 million1\text{ million} requests respectively.

Step-by-Step Solution

1
Determine the age of the AWS account from the scenario.
The AWS account is 1414 months old, which means the introductory 12-Month Free Tier period has expired.
This determines which categories of the AWS Free Tier (12-Month Free vs. Always Free) still apply to the account.
2
Evaluate each service in the configurations against the remaining Free Tier categories.
Amazon S3 and Amazon EC2 belong to the 12-Month Free category and are no longer free. Amazon DynamoDB and AWS Lambda belong to the Always Free category.
This allows identification of the correct, fully covered resource configuration.

Key Concept

AWS Free Tier offers are split into three categories: Always Free, 12-Month Free, and Trials. Always Free offers do not expire after the first 12 months of the account.

Question 1324Question

A financial services startup is deploying two workloads on Amazon EC2. The first is a core transaction ledger database that must run continuously with predictable performance and cannot tolerate any service interruptions. The second is a high-throughput, containerized credit-scoring batch analysis job that is stateless, can be safely paused and resumed, and is scheduled to run overnight. Which two of the following EC2 pricing models should the company select to minimize costs for these workloads?

Select all that apply

Show answer & explanation

Answer: Savings Plans to host the core transaction ledger database to benefit from reduced rates for a consistent amount of compute usage.; Spot Instances to run the credit-scoring batch analysis to take advantage of spare EC2 capacity at steep discounts.

Answer

Savings Plans should be used for the core transaction ledger database to benefit from reduced rates for consistent usage, and Spot Instances should be used for the credit-scoring batch analysis to utilize spare compute capacity at a lower cost.
The correct pricing strategy uses Savings Plans for the continuous, steady-state transaction database, which provides a significant discount over On-Demand rates in exchange for a commitment to consistent compute usage. For the credit-scoring batch analysis, Spot Instances are the optimal choice because the job is stateless and can tolerate interruptions, allowing the company to run it at a fraction of the cost using spare capacity.

Step-by-Step Solution

1
Analyze the requirements for the first workload (core transaction ledger database).
The workload runs continuously, requires predictable performance, and cannot tolerate interruptions.
This steady-state, continuous database workload is ideal for commitment-based discount models like Savings Plans or Reserved Instances to minimize cost.
2
Analyze the requirements for the second workload (credit-scoring batch analysis).
The workload is containerized, stateless, runs overnight, and can tolerate interruptions (paused and resumed).
Because the workload is fault-tolerant and flexible, Spot Instances are the most cost-effective choice, offering up to a 90% discount by utilizing spare EC2 capacity.
3
Combine the optimal pricing models to select the two correct choices.
Select the option for Savings Plans for the database, and the option for Spot Instances for the batch job.
This combination achieves the lowest cost while meeting the technical requirements of both workloads.

Key Concept

Selecting the optimal Amazon EC2 pricing model based on workload characteristics (steady-state vs. fault-tolerant/intermittent).

The CFO wants to understand the economic advantages of moving these workloads to the cloud. Which of the following options represent key cloud economic benefits for this scenario? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: Paying only for the compute resources consumed during active simulation runs, aligning operational expenses with actual usage.; Reducing waste by automatically scaling down compute capacity when simulations are not active.

Answer

Paying only for the compute resources consumed during active simulation runs, aligning operational expenses with actual usage, and reducing waste by automatically scaling down compute capacity when simulations are not active.
The correct options are the statements regarding paying only for the compute resources consumed during active simulation runs and reducing waste by automatically scaling down compute capacity when simulations are not active. Paying only for active use aligns expenses with actual demand, and using elasticity to scale down prevents paying for idle compute time.

Step-by-Step Solution

1
Analyze the business scenario and current challenges.
The startup runs sporadic simulation workloads and has a high amount of idle capacity (on-premises servers sized for peak demand sitting idle).
Understanding the baseline operational challenges helps target the specific economic benefits of the AWS Cloud that address them.
2
Evaluate how AWS pricing models apply to sporadic workloads.
AWS pay-as-you-go pricing allows paying only for what is used (operating expenses) rather than buying servers upfront (capital expenses).
This directly maps to the economic benefit of matching operational costs to usage.
3
Evaluate how AWS scaling features apply to idle resources.
Leveraging elasticity allows resources to scale up during simulations and down to zero during idle periods, eliminating waste.
This directly maps to the economic benefit of elasticity and cost optimization in the cloud.

Key Concept

Cloud economics focuses on replacing upfront capital expenses with variable operational expenses, and optimizing costs through elasticity and utility-based pricing.

Answer: Multiple Availability Zones; AWS Edge Locations

Answer

To survive a data center outage, the database must be deployed across multiple Availability Zones. To cache and distribute game files globally with low latency, the studio must use AWS Edge Locations.
Deploying resources across multiple Availability Zones provides local redundancy because each zone is an isolated location with independent power and cooling within an AWS Region. AWS Edge Locations cache content globally, allowing users to download large patch files from locations closest to them rather than pulling from the origin server every time.

Step-by-Step Solution

1
Analyze the first requirement: ensuring database operations remain functional during a local data center power outage.
Identify Availability Zones as the isolated infrastructure components within a Region designed to handle single-site failures.
Availability Zones consist of one or more discrete data centers with redundant power, networking, and connectivity, making them the primary tool for high availability within a region.
2
Analyze the second requirement: distributing large static files (game patches) globally with minimal latency.
Identify AWS Edge Locations as the caching network endpoints.
Edge Locations work with Amazon CloudFront to cache content closer to end-users globally, reducing latency and download times.
