Availability Zone: Availability Zones are isolated locations within a Region with independent infrastructure designed to avoid shared single points of failure. This does not address the need for A retailer wants to select the metropolitan geography nearest to most of its users for deployment. The appropriate AWS Region applies because A Region is a separate AWS geographic area containing multiple isolated Availability Zones.

Local security group limits instance or ENI traffic and does not replace central multi-account policy governance. This does not address the need for A retailer wants to select the metropolitan geography nearest to most of its users for deployment. The appropriate AWS Region applies because A Region is a separate AWS geographic area containing multiple isolated Availability Zones.

Edge location: Serves edge network traffic and caching, not core application AZ placement. This does not address the need for A retailer wants to select the metropolitan geography nearest to most of its users for deployment. The appropriate AWS Region applies because A Region is a separate AWS geographic area containing multiple isolated Availability Zones.

IAM policy: Governs AWS API access permissions rather than network packet filtering. That does not meet the requirement: An architect wants to place redundant servers in isolated facilities within one AWS Region.

Edge location: Serves edge network traffic and caching, not core application AZ placement. That does not meet the requirement: An architect wants to place redundant servers in isolated facilities within one AWS Region.

S3 bucket prefix is an object key naming convention, not an isolated infrastructure facility. That does not meet the requirement: An architect wants to place redundant servers in isolated facilities within one AWS Region.

The appropriate Availability Zone applies because Availability Zones are isolated locations within a Region with independent infrastructure designed to avoid shared single points of failure.

S3 bucket prefix is an object key naming convention, not an isolated infrastructure facility. That does not meet the requirement: Consider this AWS requirement: A business wants to reduce the impact of a single facility failure without changing geography.

IAM policy: Governs AWS API access permissions rather than network packet filtering. That does not meet the requirement: Consider this AWS requirement: A business wants to reduce the impact of a single facility failure without changing geography.

Only larger EC2 capacity: Increases compute size without independently ensuring application availability. That does not meet the requirement: A production application needs redundancy when one Availability Zone suffers an outage.

Single-AZ architecture places the workload within one AZ, so an AZ outage can affect all copies. That does not meet the requirement: A production application needs redundancy when one Availability Zone suffers an outage.

More IAM users: Increases identities but does not create a least-privilege or centralized governance solution by itself. That does not meet the requirement: A production application needs redundancy when one Availability Zone suffers an outage.

Single-AZ architecture places the workload within one AZ, so an AZ outage can affect all copies. This does not address the need for A production application needs redundancy when one Availability Zone suffers an outage. The appropriate Multi-AZ architecture applies because Distributing components over independent AZs reduces exposure to a single-AZ outage.

Only larger EC2 capacity: Increases compute size without independently ensuring application availability. This does not address the need for A production application needs redundancy when one Availability Zone suffers an outage. The appropriate Multi-AZ architecture applies because Distributing components over independent AZs reduces exposure to a single-AZ outage.

The appropriate Multi-AZ architecture applies because Distributing components over independent AZs reduces exposure to a single-AZ outage.

Single-AZ architecture places the workload within one AZ, so an AZ outage can affect all copies. That does not meet the requirement: A technical reviewer evaluates this need: A database team wants service continuity during an AZ failure in the same Region.

Single edge cache: Holds cached content and is not multi-Region application recovery. That does not meet the requirement: An organization needs recovery options if an entire geographic AWS Region becomes unavailable.

Single-AZ deployment places resources in one Availability Zone rather than spreading risk across AZs. That does not meet the requirement: An organization needs recovery options if an entire geographic AWS Region becomes unavailable.

Single-Region Multi-AZ only: Improves AZ fault tolerance within one Region but does not protect against a full-Region outage. That does not meet the requirement: An organization needs recovery options if an entire geographic AWS Region becomes unavailable.

Single-AZ deployment places resources in one Availability Zone rather than spreading risk across AZs. This does not address the need for An organization needs recovery options if an entire geographic AWS Region becomes unavailable. The appropriate Multi-Region deployment applies because Using more than one Region can improve resilience to region-level failures when data and services are replicated appropriately.
