An organization wants to cut cost by consolidating lightly used physical machines into flexible cloud resources.
Which observation would best confirm that the intended cloud outcome is being achieved?
Shared infrastructure can avoid some overprovisioning associated with dedicated underused local equipment.
License ownership and eligible product rules determine whether a bring-your-own-license option is suitable.
Discounted commitment models may reduce eligible usage rates while increasing obligations when demand changes.
Cloud choices vary in who manages software, patching and operations, affecting labor and maintenance cost.
A regional organization needs hybrid network access without provisioning a dedicated physical private circuit.
Which observation would best confirm that the intended cloud outcome is being achieved?
AWS VPN establishes encrypted tunnels between customer networks and AWS network endpoints.
Route 53 provides DNS hosting and routing features for internet-accessible names.
A VPC contains configured networking components such as subnets, routes and gateways.
Direct Connect provides private dedicated connectivity rather than an ordinary public-internet VPN tunnel.
An application needs inbound rules that are stateful and attached to its EC2 instances.
Which AWS concept, service, or approach best meets the need described?
Security groups are stateful controls associated with eligible network interfaces and resources. For the described requirement, use VPC security groups for stateful instance-level traffic filtering.
Network ACLs evaluate inbound and outbound subnet traffic independently and are stateless.
AWS VPN establishes encrypted tunnels between customer networks and AWS network endpoints.
NAT gateways support outbound internet access through a public route while not providing unsolicited inbound initiation.
An analytics team runs an occasional monthly batch task and otherwise leaves dedicated machines unused.
Which AWS concept, service, or approach best meets the need described?
Elastic self-service consumption can improve efficiency when unnecessary resources are stopped or released. For the described requirement, deprovision idle cloud resources so charges better reflect the actual work performed.
Provisioning through AWS APIs and consoles improves agility by reducing procurement delays for new environments.
Elasticity aligns provisioned resources with current need instead of maintaining permanent peak-sized local capacity.
AWS supplies resilient infrastructure options but application architecture and chosen deployment patterns still affect availability.
A team wants managed event routing based on an event's attributes instead of polling each producer.
Which AWS concept, service, or approach best meets the need described?
EventBridge routes matching events from supported sources to configured destinations. For the described requirement, use Amazon EventBridge for rule-based event routing to selected targets.
Amazon SES supports sending emails and is distinct from contact-center voice workflows.
IoT Core supports communication between approved devices and cloud services.
Amazon Connect supports contact-center interactions and routing rather than bulk marketing email delivery.
A business intelligence group needs dashboards from several data sources.
Which AWS concept, service, or approach best meets the need described?
QuickSight provides managed visualization and analytical dashboard capabilities. For the described requirement, use Amazon QuickSight for supported cloud business intelligence dashboards.
Kinesis provides streaming-data services rather than a long-term relational warehouse.
Lex provides bot-building features including speech and natural-language intent processing.
Athena supports serverless interactive SQL analysis of data stored in S3.
A growing company needs a simple virtual private server solution for a basic website with predictable needs.
Which observation would best confirm that the intended cloud outcome is being achieved?
Lightsail offers simplified VPS plans with predictable bundles for straightforward applications.
Amazon ECS manages placement and service operation of containers in an AWS-native orchestration model.
A load balancer forwards requests to configured healthy application targets and supports availability.
Auto Scaling can increase and decrease EC2 instance count based on configured policies and signals.
A company wants cloud design decisions to consider the environmental impact of workloads.
Which AWS concept, service, or approach best meets the need described?
Sustainability encourages efficient resource usage and avoiding unnecessary capacity and processing. For the described requirement, use the sustainability pillar to reduce environmental impacts across the workload life cycle.
The security pillar focuses on protecting systems and data using appropriate identity and detection controls.
Operational failures from unsafe processes require process and automation improvement, not simply bigger resources.
Selecting fit-for-purpose resources meets performance needs without automatically overprovisioning.
A cloud learner asks which global infrastructure units are isolated for high availability inside a 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.
Choosing Region determines the geographic location of many deployed resources and data residency choices.
Multiple instances sharing one AZ remain exposed to an AZ-wide event despite instance-level redundancy.
A Region is a geographic AWS area containing multiple isolated Availability Zones.
A regional booking portal cannot tolerate interruption when an individual computing facility loses power.
Which observation would best confirm that the intended cloud outcome is being achieved?
Availability Zones are isolated fault locations within a Region and reduce dependency on one data-center location.
AWS global infrastructure enables geographic reach and faster regional market entry while the business remains responsible for its application.
Variable pricing links many cloud expenses to provisioned capacity and consumption while owned equipment has upfront fixed costs.
Elastic self-service consumption can improve efficiency when unnecessary resources are stopped or released.
A research lab needs low-cost computing for flexible jobs that tolerate sudden termination.
Which AWS pricing, billing, or support approach best matches the requirement?
Spot capacity can be discounted but may be reclaimed with interruption notices and is unsuitable for uninterrupted critical jobs. For the described requirement, choose EC2 Spot Instances for interruption-tolerant workloads.
On-Demand billing allows eligible EC2 capacity without an upfront duration commitment, though its unit price may be higher.
Savings Plans trade a spend commitment for discounted eligible compute usage and differ in flexibility by plan type.
Dedicated Hosts provide single-customer physical server tenancy and host-level allocation features for supported licensing needs.
