Question 1160
A stakeholder is considering EC2 Spot Instances because a research team runs flexible batch processing jobs that can tolerate interruption. What is the MOST relevant capability or benefit?
- Pay for eligible compute usage without a long-term purchase commitment
- Account for service- and route-dependent data transfer pricing
- Reserve eligible compute capacity without necessarily purchasing a usage discount
- Meet this requirement: a research team runs flexible batch processing jobs that can tolerate interruption
Explanation
Correct Answer
D:Use spare EC2 capacity at a discount with interruption risk. EC2 Spot Instances offer discounted unused capacity but can be reclaimed with interruption notices. The stated need is specifically a research team runs flexible batch processing jobs that can tolerate interruption.
Incorrect Answers
A:This outcome fits On-Demand EC2 pricing: On-Demand pricing gives flexible capacity for irregular or new workloads, generally without the discounts of eligible commitments. The stakeholder requires the more specific capability provided by EC2 Spot Instances, not that separate benefit.
B:This outcome fits AWS data transfer charges: Data entering AWS is often priced differently from outbound or cross-Region traffic; actual charges depend on service and path. The stakeholder requires the more specific capability provided by EC2 Spot Instances, not that separate benefit.
C:This outcome fits On-Demand Capacity Reservations: An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction. The stakeholder requires the more specific capability provided by EC2 Spot Instances, not that separate benefit.
Question 1161
A stakeholder is considering Amazon RDS because a web application needs a managed relational database that supports SQL queries and transactions. What is the MOST relevant capability or benefit?
- Enable supported relational engines
- Support cloud data warehousing
- Support managed in-memory caching
- Support database transfer and applicable ongoing replication
Explanation
Correct Answer
A:Use Amazon Relational Database Service for supported relational engines. RDS manages selected database infrastructure work for relational workloads, while users still control database schema and access. The stated need is specifically a web application needs a managed relational database that supports SQL queries and transactions.
Incorrect Answers
B:This outcome fits Amazon Redshift: Redshift is designed for analytics and data warehousing rather than being a low-latency transactional key-value store. The stakeholder requires the more specific capability provided by Amazon RDS, not that separate benefit.
C:This outcome fits Amazon ElastiCache: ElastiCache reduces repeated backend reads by keeping appropriate data in memory for fast access. The stakeholder requires the more specific capability provided by Amazon RDS, not that separate benefit.
D:This outcome fits AWS Database Migration Service: Database Migration Service helps migrate or replicate supported databases; it is not itself an application database engine. The stakeholder requires the more specific capability provided by Amazon RDS, not that separate benefit.
Question 1162
A learner is explaining Reduced infrastructure maintenance to colleagues facing this situation: a small team prefers to focus on application features instead of replacing failed server hardware. Which explanation is MOST accurate?
- Durability describes the likelihood that stored data remains intact; it is different from immediate service accessibility.
- AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks.
- Business continuity combines preparedness and recovery measures rather than assuming failures will never occur.
- AWS Regions enable deployment in multiple geographies without building and operating a physical data center in each market.
Explanation
Correct Answer
B:AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks. The explanation directly connects Reduced infrastructure maintenance to delegate physical infrastructure operation to the cloud provider for the stated requirement.
Incorrect Answers
A:This statement is true of Storage durability, which addresses a photo service needs stored customer pictures to remain intact despite individual storage hardware failures. It does not explain the particular role of Reduced infrastructure maintenance; AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks.
C:This statement is true of Business continuity, which addresses a retailer needs a plan for resuming critical operations after a major disruption. It does not explain the particular role of Reduced infrastructure maintenance; AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks.
D:This statement is true of Global reach, which addresses a software provider wants to serve customers from multiple continents without building overseas data centers. It does not explain the particular role of Reduced infrastructure maintenance; AWS handles the facilities and underlying physical infrastructure, freeing customers from those data-center tasks.
Question 1163
A project manager compares Sustainability pillar with other AWS concepts while considering this need: a company wants to reduce the environmental impact of its cloud workloads. Which pairing assigns the responsibilities or benefits correctly?
- Sustainability pillar: revisit architecture decisions as requirements and capabilities change; Design for expected change: minimize energy consumption and environmental impact per unit of work
- Sustainability pillar: protect information and systems using risk-aware controls; Security pillar: minimize energy consumption and environmental impact per unit of work
- Sustainability pillar: minimize energy consumption and environmental impact per unit of work; Security pillar: protect information and systems using risk-aware controls
- Sustainability pillar: use computing resources efficiently as requirements change; Performance Efficiency pillar: minimize energy consumption and environmental impact per unit of work
Explanation
Correct Answer
C:The first pairing identifies Sustainability pillar with its actual role: minimize energy consumption and environmental impact per unit of work. The Sustainability pillar encourages efficient resource use and reduced environmental impact of running workloads. The comparison is valid because Security pillar instead addresses protect information and systems using risk-aware controls.
Incorrect Answers
A:The roles are swapped. Design for expected change is associated with revisit architecture decisions as requirements and capabilities change; Sustainability pillar instead has the role: Minimize energy consumption and environmental impact per unit of work. The Sustainability pillar encourages efficient resource use and reduced environmental impact of running workloads.
B:The roles are swapped. Security pillar is associated with protect information and systems using risk-aware controls; Sustainability pillar instead has the role: Minimize energy consumption and environmental impact per unit of work. The Sustainability pillar encourages efficient resource use and reduced environmental impact of running workloads.
D:The roles are swapped. Performance Efficiency pillar is associated with use computing resources efficiently as requirements change; Sustainability pillar instead has the role: Minimize energy consumption and environmental impact per unit of work. The Sustainability pillar encourages efficient resource use and reduced environmental impact of running workloads.
Question 1164
Within the Security and Compliance domain, which business example MOST clearly illustrates Identity federation, rather than a different AWS concept?
- A legacy automation application uses an AWS access-key ID and secret key for API access
- A security team wants to identify unintended external access to supported AWS resources
- A team needs to assign the same AWS permissions to several IAM users
- A company wants staff to authenticate to AWS using its existing corporate identity provider
Explanation
Correct Answer
D:The decisive requirement is: Federate existing enterprise identities instead of issuing separate permanent credentials. This is the role of Identity federation. Federation integrates identity-provider authentication with AWS access, supporting centralized workforce identity management.
Incorrect Answers
A:This describes a scenario for Access keys: treat access keys as sensitive credentials and rotate or replace them where appropriate. AWS access keys enable programmatic authentication and must not be committed to public repositories. It is not the most direct example of Identity federation.
B:This describes a scenario for IAM Access Analyzer: use IAM Access Analyzer to examine resource access and policy exposure. Access Analyzer helps identify access findings; it does not by itself remove the underlying excessive permissions. It is not the most direct example of Identity federation.
C:This describes a scenario for IAM groups: use an IAM group to manage shared user permissions. IAM groups collect IAM users for permissions management; they are not assumed identities like IAM roles. It is not the most direct example of Identity federation.
Question 1165
Within the Cloud Technology and Services domain, which business example MOST clearly illustrates Amazon SageMaker AI, rather than a different AWS concept?
- A machine learning team needs tools to build and deploy custom ML models
- A business wants dashboards and business intelligence over curated organizational data
- An analyst needs to query data already stored in S3 using SQL without provisioning a database server
- A data team needs managed data integration and metadata catalog features for analytics workloads
Explanation
Correct Answer
A:The decisive requirement is: Use Amazon SageMaker AI for managed machine learning development workflows. This is the role of Amazon SageMaker AI. SageMaker AI supports building, training and deploying ML models rather than simply translating text.
Incorrect Answers
B:This describes a scenario for Amazon Quick: use Amazon Quick for supported business intelligence and analytics experiences. Amazon Quick is the current AWS branding for business intelligence capabilities previously associated with QuickSight. It is not the most direct example of Amazon SageMaker AI.
C:This describes a scenario for Amazon Athena: use Amazon Athena for interactive SQL analysis over data in S3. Athena is a serverless interactive query service for supported data sources such as S3. It is not the most direct example of Amazon SageMaker AI.
D:This describes a scenario for AWS Glue: use AWS Glue for data integration, ETL and catalog features. Glue supports preparing and cataloging data; it is not the primary object storage service. It is not the most direct example of Amazon SageMaker AI.
Question 1166
A learner is explaining Customer encryption choices to colleagues facing this situation: a company wants to ensure its application stores sensitive objects with required encryption settings. Which explanation is MOST accurate?
- Responsibility depends on the service model: managing an EC2 guest OS differs from managing application code on Lambda.
- Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data.
- Serverless eliminates server administration for the customer, not their responsibility for their own application code and data handling.
- AWS handles service infrastructure, while customers still control object permissions, classifications and retention requirements.
Explanation
Correct Answer
B:Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data. The explanation directly connects Customer encryption choices to the customer chooses applicable encryption configuration and key-access policies for the stated requirement.
Incorrect Answers
A:This statement is true of Shared responsibility varies by service, which addresses a technology leader compares the management obligations of EC2, RDS and Lambda. It does not explain the particular role of Customer encryption choices; Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data.
C:This statement is true of Customer Lambda function code, which addresses a Lambda function processes user data using application code written by a development team. It does not explain the particular role of Customer encryption choices; Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data.
D:This statement is true of AWS S3 infrastructure durability, which addresses a customer asks who maintains the physical storage systems used by Amazon S3. It does not explain the particular role of Customer encryption choices; Managed services can provide encryption capabilities, but customers must select and govern settings needed for their data.
Question 1167
A stakeholder is considering AWS WAF application protection because a public website needs rules to inspect common malicious HTTP requests. What is the MOST relevant capability or benefit?
- Meet this requirement: an organization needs general recommendations to harden AWS workloads
- Meet this requirement: a company wants to evaluate a third-party security product compatible with AWS workloads
- Filter supported web requests
- Manage supported security policies centrally
Explanation
Correct Answer
C:Use AWS WAF to filter supported web requests. WAF acts at web request level and can help mitigate common HTTP attack patterns. The stated need is specifically a public website needs rules to inspect common malicious HTTP requests.
Incorrect Answers
A:This outcome fits AWS security best practices: AWS security guidance supports safe decisions, while controls still need deliberate configuration by the customer. The stakeholder requires the more specific capability provided by AWS WAF application protection, not that separate benefit.
B:This outcome fits AWS Marketplace security software: Marketplace lets customers discover and procure partner solutions; it is not the same as an AWS native security monitoring service. The stakeholder requires the more specific capability provided by AWS WAF application protection, not that separate benefit.
D:This outcome fits AWS Firewall Manager policy oversight: Firewall Manager helps manage AWS WAF, Shield and related policies across an AWS Organizations environment. The stakeholder requires the more specific capability provided by AWS WAF application protection, not that separate benefit.
Question 1168
A company needs centralized governance across many separate AWS accounts. Which AWS service or cloud concept is the MOST direct match for this need?
- Encryption in transit
- AWS compliance shared model
- AWS CloudHSM
- AWS Organizations
Explanation
Correct Answer
D:AWS Organizations fits the need because organizations groups accounts and supports policies and billing consolidation; it does not itself analyze threats. The relevant capability or responsibility is: Use AWS Organizations for multi-account governance and consolidated controls.
Incorrect Answers
A:Encryption in transit is associated with a different use case: a company wants to protect data while it moves between clients and an online service. Encryption in transit protects communications over networks; it differs from encryption of data stored on disks. The question instead focuses on a company needs centralized governance across many separate AWS accounts; AWS Organizations is the more direct match.
B:AWS compliance shared model is associated with a different use case: a regulated company assumes AWS compliance certificates automatically satisfy every customer-specific obligation. AWS compliance programs cover AWS's side of applicable frameworks, while customers must evaluate and satisfy their own duties. The question instead focuses on a company needs centralized governance across many separate AWS accounts; AWS Organizations is the more direct match.
C:AWS CloudHSM hardware keys is associated with a different use case: a company needs dedicated hardware security modules for particular cryptographic key requirements. CloudHSM provides customer-controlled HSM capacity for supported workloads requiring hardware-backed cryptographic operations. The question instead focuses on a company needs centralized governance across many separate AWS accounts; AWS Organizations is the more direct match.
Question 1169
An administrator needs separate IP address ranges for application and database resources within one VPC. Which AWS service or cloud concept is the MOST direct match for this need?
- VPC subnets
- AWS Site-to-Site VPN
- Network ACLs
- Amazon Route 53
Explanation
Correct Answer
A:VPC subnets fits the need because each subnet belongs to one Availability Zone and can have network and routing controls. The relevant capability or responsibility is: Use VPC subnets to divide VPC address space into smaller networks.
Incorrect Answers
B:AWS Site-to-Site VPN is associated with a different use case: a company wants an encrypted tunnel between an office network and its AWS VPC over the internet. Site-to-Site VPN provides encrypted tunnels using internet-based connectivity, subject to supported gateway arrangements. The question instead focuses on an administrator needs separate IP address ranges for application and database resources within one VPC; VPC subnets is the more direct match.
C:Network ACLs is associated with a different use case: a VPC owner needs network traffic rules at the subnet boundary and wants stateless filtering. VPC network ACLs apply to subnets and are stateless, unlike security groups' stateful behavior. The question instead focuses on an administrator needs separate IP address ranges for application and database resources within one VPC; VPC subnets is the more direct match.
D:Amazon Route 53 is associated with a different use case: a business needs a managed DNS service for resolving public application domain names. Route 53 supplies managed DNS records and routing policies, rather than acting as a virtual machine host. The question instead focuses on an administrator needs separate IP address ranges for application and database resources within one VPC; VPC subnets is the more direct match.
Question 1170
A company wants to transfer database content to AWS while limiting downtime. Which AWS service or cloud concept is the MOST direct match for this need?
- AWS Application Migration Service
- AWS Database Migration Service
- Replatforming migration
- Repurchasing migration
Explanation
Correct Answer
B:AWS Database Migration Service fits the need because aWS DMS can transfer data and support change data capture for applicable database migration scenarios. The relevant capability or responsibility is: Migrate and optionally replicate data between supported database endpoints.
Incorrect Answers
A:AWS Application Migration Service is associated with a different use case: an enterprise needs to lift and shift many supported physical or virtual servers to AWS. AWS Application Migration Service supports continuous replication and cutover for eligible servers. The question instead focuses on a company wants to transfer database content to AWS while limiting downtime; AWS Database Migration Service is the more direct match.
C:Replatforming migration is associated with a different use case: a company moves an application to AWS and also adopts a managed database without rebuilding its business logic. Replatforming adjusts selected supporting components to gain cloud benefits without a full application rewrite. The question instead focuses on a company wants to transfer database content to AWS while limiting downtime; AWS Database Migration Service is the more direct match.
D:Repurchasing migration is associated with a different use case: an organization replaces its custom on-premises collaboration tool with a commercial SaaS subscription. Repurchasing changes the software product consumed instead of moving the same application stack. The question instead focuses on a company wants to transfer database content to AWS while limiting downtime; AWS Database Migration Service is the more direct match.
