An auditor asks who installs application patches inside a customer-managed virtual machine hosted by AWS.
Which AWS concept, service, or approach best meets the need described?
AWS secures the underlying virtualization and facilities, while EC2 customers administer operating systems they install. For the described requirement, assign guest operating system and application patching on EC2 to the customer.
Customer OS patching is greater for EC2 than Lambda, while code and data responsibilities remain with the customer.
AWS operates physical infrastructure, whereas EC2 customer workloads retain OS and data responsibilities.
RDS reduces customer responsibility for host and engine administration compared with hosting a database directly on EC2.
A new organization wants staff to sign in to multiple AWS accounts using an existing workforce identity source.
Which AWS concept, service, or approach best meets the need described?
Identity Center manages workforce assignments and federation rather than sharing static IAM user credentials. For the described requirement, use IAM Identity Center for centralized workforce access to supported AWS accounts.
Sign-in success is not sufficient; identity and resource policies and explicit denies influence authorization.
IAM roles supply temporary credentials for authorized workloads and avoid hard-coded long-term keys.
IAM policies express permitted actions on supported resources; broad wildcard privileges are usually unnecessary.
A freelancer wants a streamlined AWS application hosting package rather than managing many infrastructure services.
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 EKS provides AWS-managed Kubernetes control-plane capabilities for Kubernetes-based applications.
EC2 provides virtual machine capacity while the customer manages the installed operating system and applications.
Compute-optimized families provide a higher ratio of processing capacity for eligible CPU-bound tasks.
An archive is rarely read and the company wants a cheaper storage tier with different retrieval characteristics.
Which observation would best confirm that the intended cloud outcome is being achieved?
Lower storage rates can involve retrieval fees, time delays or duration requirements depending on class.
On-Demand billing allows eligible EC2 capacity without an upfront duration commitment, though its unit price may be higher.
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.
A bank evaluates how to recover normal service after an unexpected dependency outage.
Which AWS concept, service, or approach best meets the need described?
Reliability addresses fault recovery, capacity to meet demand, and resilient operation. For the described requirement, use the reliability pillar to design recovery and consistent service availability.
Cost optimization focuses on spending that delivers business value, including usage visibility and demand matching.
The pillars are operational excellence, security, reliability, performance efficiency, cost optimization and sustainability, not individual AWS services.
Operational failures from unsafe processes require process and automation improvement, not simply bigger resources.
A small office wants a hybrid storage interface without relocating all local file consumers at once.
Which observation would best confirm that the intended cloud outcome is being achieved?
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.
FSx for Windows File Server is a managed file option for Windows-compatible shared access.
AWS Backup centralizes backup configuration for supported AWS resource types.
An IT manager asks for managed workload scanning for known software vulnerabilities.
Which observation would best confirm that the intended cloud outcome is being achieved?
Inspector analyzes supported workloads for exposure and software vulnerabilities, not user login events.
GuardDuty uses supported signals to report suspected threats rather than inventorying all business contracts.
AWS Marketplace lists third-party offerings and procurement options alongside AWS service integrations.
WAF inspects HTTP requests with web ACL rules and complements rather than replaces network-layer controls.
A retail site needs to reduce repeated primary-database reads for frequently accessed product data.
Which observation would best confirm that the intended cloud outcome is being achieved?
ElastiCache supports low-latency in-memory access and can reduce load on a persistent system of record.
Amazon Redshift is designed for analytics and warehouse workloads rather than conventional app transactions.
Amazon RDS operates supported relational databases with managed infrastructure and routine platform tasks.
Aurora is AWS's managed relational engine designed for cloud operation and supported compatibility.
An IT team needs centrally managed backup schedules across several supported AWS services.
Which observation would best confirm that the intended cloud outcome is being achieved?
AWS Backup centralizes backup configuration for supported AWS resource types.
EBS supplies block volumes for compatible EC2 instances rather than shared internet-facing object buckets.
Instance store is physically attached ephemeral storage and must not hold data requiring persistence through host loss.
FSx for Windows File Server is a managed file option for Windows-compatible shared access.
A software product needs to call AWS service features directly from its application code.
Which AWS concept, service, or approach best meets the need described?
AWS SDKs provide language-specific clients for application interactions with AWS APIs. For the described requirement, use an AWS SDK for the application's AWS service API integration.
AWS APIs can be called by scripts and tools to standardize supported tasks at scale.
AWS public cloud is provider-operated multi-tenant infrastructure; customer data access still depends on security controls.
The console offers a graphical interface appropriate for human-directed AWS service inspection.
A product team needs to forecast the price of a proposed architecture before creating its resources.
Which observation would best confirm that the intended cloud outcome is being achieved?
Pricing Calculator models estimated charges for configured usage assumptions before deployment.
Cost and Usage reports provide granular cost and usage data for analysis rather than a simple monthly invoice summary.
AWS Budgets compares actual and forecast cost to budget thresholds and can notify stakeholders.
Consolidated billing enables central management of multiple account bills and eligible shared pricing benefits.
