Several Linux EC2 instances need concurrent access to the same shared file directory.
Which observation would best confirm that the intended cloud outcome is being achieved?
EFS provides elastic shared file access rather than an individual EC2 block disk.
EBS supplies block volumes for compatible EC2 instances rather than shared internet-facing object buckets.
S3 Lifecycle automates supported tier changes and expirations based on defined rules.
AWS Backup centralizes backup configuration for supported AWS resource types.
An IT manager needs automated detection of software vulnerabilities in supported AWS resources.
Which AWS concept, service, or approach best meets the need described?
Inspector identifies vulnerabilities and related exposure in supported compute resources. For the described requirement, use Amazon Inspector for eligible workload vulnerability assessments.
Security Hub centralizes findings and security posture visibility instead of being a standalone packet firewall.
GuardDuty analyzes supported data sources to identify suspicious activity rather than performing a general resource inventory.
Stored-object encryption protects persisted content; transport encryption protects communication between endpoints.
A transformation team wants to improve operating efficiency and reduce migration-related risk.
Which AWS concept, service, or approach best meets the need described?
AWS CAF considers business risk, efficiency, revenue opportunity and broader transformation outcomes. For the described requirement, apply AWS CAF business outcomes to assess readiness and measure adoption value.
Replatforming changes selected platform components while retaining the application's fundamental design.
Refactoring involves significant application design changes to exploit cloud-native capabilities.
Repurchasing substitutes a new product licensing and delivery model for a legacy implementation.
A company has a steady predictable baseline of EC2 compute use over several years.
Which observation would best confirm that the intended cloud outcome is being achieved?
Reserved Instance pricing offers commitment-based discounts subject to instance attributes and purchasing terms.
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.
Capacity Reservations address eligible instance-capacity availability rather than inherently reducing the cost of the instances.
A management team wants automated account recommendations on eligible operational and security best-practice checks.
Which observation would best confirm that the intended cloud outcome is being achieved?
Trusted Advisor assesses selected account conditions rather than providing a general-purpose support ticket inbox.
AWS documentation is the primary provider-maintained reference for supported service behavior.
Support Center provides case management according to the account's plan and support entitlement.
AWS re:Post provides community-style knowledge sharing and is not a substitute for a contractual support case.
A university needs a cost justification for replacing scattered single-purpose servers with centrally operated cloud capacity.
Which AWS concept, service, or approach best meets the need described?
Shared infrastructure can avoid some overprovisioning associated with dedicated underused local equipment. For the described requirement, use more efficient shared resource utilization in the cloud economics business case.
Discounted commitment models may reduce eligible usage rates while increasing obligations when demand changes.
Cloud economics includes business agility and opportunity value, not merely monthly compute prices.
Cloud consumption pricing can shift spending from equipment purchase to charges based on service usage.
A company wants encrypted traffic between its office and AWS across an existing internet connection.
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.
Direct Connect provides private dedicated connectivity rather than an ordinary public-internet VPN tunnel.
A VPC contains configured networking components such as subnets, routes and gateways.
Route 53 provides DNS hosting and routing features for internet-accessible names.
A team wants managed event routing based on an event's attributes instead of polling each producer.
Which observation would best confirm that the intended cloud outcome is being achieved?
EventBridge routes matching events from supported sources to configured destinations.
Amazon SES supports sending emails and is distinct from contact-center voice workflows.
IoT Core supports communication between approved devices and cloud services.
SNS can distribute published messages to configured endpoints and subscribers.
An events team wants compute availability reserved for a planned launch without assuming discounted usage prices.
Which AWS pricing, billing, or support approach best matches the requirement?
Capacity Reservations address eligible instance-capacity availability rather than inherently reducing the cost of the instances. For the described requirement, use an EC2 Capacity Reservation for the required instance attributes and placement.
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.
Savings Plans trade a spend commitment for discounted eligible compute usage and differ in flexibility by plan type.
A workload must remain in a specific country to meet a documented data residency policy.
Which observation would best confirm that the intended cloud outcome is being achieved?
Choosing Region determines the geographic location of many deployed resources and data residency choices.
Edge locations bring cached content and network services closer to end users.
A Region is a geographic AWS area containing multiple isolated Availability Zones.
Availability Zones are separate fault-isolation locations within a Region.
A company wants to grant many employees the same set of IAM permissions without attaching copies individually.
Which AWS concept, service, or approach best meets the need described?
IAM user groups let administrators attach permissions once for a collection of users. For the described requirement, use an IAM user group to manage shared permissions for IAM users.
MFA adds a second authentication factor to protect against password-only compromise.
Secrets Manager is purpose-built for managing secret values instead of exposing credentials in source files.
IAM policies express permitted actions on supported resources; broad wildcard privileges are usually unnecessary.
