A customer wants automated account recommendations for security and cost best practices.
Which observation would best confirm that the intended cloud outcome is being achieved?
Trusted Advisor evaluates selected account checks and is not the same as a complete security audit.
GuardDuty uses supported signals to report suspected threats rather than inventorying all business contracts.
Shield is focused on denial-of-service defense whereas IAM evaluates principal permissions.
Firewall Manager supports organization-level security-policy management for selected AWS protection services.
A regional web service must tolerate an individual AWS data center fault within one Region.
Which AWS concept, service, or approach best meets the need described?
Availability Zones are separate fault-isolation locations within a Region. For the described requirement, place redundant resources in multiple Availability Zones within the Region.
Multiple instances sharing one AZ remain exposed to an AZ-wide event despite instance-level redundancy.
Choosing Region determines the geographic location of many deployed resources and data residency choices.
A Region is a geographic AWS area containing multiple isolated Availability Zones.
A security manager wants to identify the customer-controlled decisions behind storage encryption settings.
Which AWS concept, service, or approach best meets the need described?
AWS offers encryption features, but customers must choose appropriate configuration and manage access and key permissions. For the described requirement, assign selection and governance of customer encryption settings and data access to the customer.
Customer OS patching is greater for EC2 than Lambda, while code and data responsibilities remain with the customer.
AWS certification of infrastructure does not automatically make customer configurations or data practices compliant.
AWS is responsible for facilities, hardware and underlying infrastructure used to provide its cloud services.
A small company needs virtual machines for a three-week experiment with uncertain future demand.
Which observation would best confirm that the intended cloud outcome is being achieved?
On-Demand billing allows eligible EC2 capacity without an upfront duration commitment, though its unit price may be higher.
Dedicated Hosts provide single-customer physical server tenancy and host-level allocation features for supported licensing needs.
Lower storage rates can involve retrieval fees, time delays or duration requirements depending on class.
Reserved Instance pricing offers commitment-based discounts subject to instance attributes and purchasing terms.
A graphics processing workload wastes time because the selected resource class does not fit its compute needs.
Which AWS concept, service, or approach best meets the need described?
Performance efficiency concerns effective resource selection, adaptation and continued performance improvement. For the described requirement, use the performance efficiency pillar to select resources aligned to workload characteristics.
Sustainability encourages efficient resource usage and avoiding unnecessary capacity and processing.
The Framework is an ongoing design-assessment tool rather than a one-time certification of a deployment.
Security addresses protection from unauthorized access; reliability concerns continuing and recovering service delivery.
A growing SaaS company changes projected demand monthly and wants its operating costs to track actual use.
Which observation would best confirm that the intended cloud outcome is being achieved?
Variable pricing links many cloud expenses to provisioned capacity and consumption while owned equipment has upfront fixed costs.
Metered cloud consumption lowers initial capital outlay and supports experiments with uncertain future demand.
Provisioning through AWS APIs and consoles improves agility by reducing procurement delays for new environments.
AWS supplies resilient infrastructure options but application architecture and chosen deployment patterns still affect availability.
A department wants threshold alerts before its cloud spend exceeds a quarterly allowance.
Which AWS pricing, billing, or support approach best matches the requirement?
AWS Budgets compares actual and forecast cost to budget thresholds and can notify stakeholders. For the described requirement, use AWS Budgets to set a cost budget and threshold notifications.
Cost and Usage reports provide granular cost and usage data for analysis rather than a simple monthly invoice summary.
Consolidated billing enables central management of multiple account bills and eligible shared pricing benefits.
Cost allocation tags can group expenses in supported billing tools after appropriate activation.
An audit department wants to minimize storage cost while accepting slower data retrieval.
Which observation would best confirm that the intended cloud outcome is being achieved?
S3 archival classes trade access characteristics for lower storage costs on eligible archived data.
EFS provides elastic shared file access rather than an individual EC2 block disk.
Storage Gateway connects local storage protocols and caching patterns to AWS cloud storage services.
S3 stores objects in buckets and is not mounted like an ordinary instance block device.
A research lab needs low-cost computing for flexible jobs that tolerate sudden termination.
Which observation would best confirm that the intended cloud outcome is being achieved?
Spot capacity can be discounted but may be reclaimed with interruption notices and is unsuitable for uninterrupted critical jobs.
Capacity Reservations address eligible instance-capacity availability rather than inherently reducing the cost of the instances.
Reserved Instance pricing offers commitment-based discounts subject to instance attributes and purchasing terms.
On-Demand billing allows eligible EC2 capacity without an upfront duration commitment, though its unit price may be higher.
A database team wants a compute instance category prioritizing RAM capacity for an application.
Which observation would best confirm that the intended cloud outcome is being achieved?
Memory-optimized instance categories are designed for workloads needing substantial available RAM.
Auto Scaling can increase and decrease EC2 instance count based on configured policies and signals.
Amazon ECS manages placement and service operation of containers in an AWS-native orchestration model.
Compute-optimized families provide a higher ratio of processing capacity for eligible CPU-bound tasks.
A business owner wants timely notice of service events relevant to its own AWS environment.
Which observation would best confirm that the intended cloud outcome is being achieved?
AWS Health displays service events and, where applicable, account-specific impact information.
AWS re:Post provides community-style knowledge sharing and is not a substitute for a contractual support case.
AWS documentation is the primary provider-maintained reference for supported service behavior.
Trusted Advisor assesses selected account conditions rather than providing a general-purpose support ticket inbox.
