A company sells ringtones created from clips of popular songs. The files containing the ringtones are stored in Amazon S3 Standard and are at least 128 KB in size. The company has millions of files, but downloads are infrequent for ringtones older than 90 days. The company needs to save money on storage while keeping the most accessed files readily available for its users.Which action should the company take to meet these requirements MOST cost-effectively?
Answer(s): D
S) D) is correct because an S3 Lifecycle policy can automatically transition objects from S3 Standard to S3 Standard-IA after 90 days, reducing storage costs for infrequently accessed files while keeping them readily available when needed. A) S3 Standard-IA applies to objects initially; not aligned with the requirement to start in Standard and transition later. B) S3 Intelligent-Tiering may incur unnecessary monitoring fees; though it automatically moves, it is not as cost-optimal for a predictable 90-day access pattern with large number of objects. C) S3 Inventory is a reporting feature, not an automatic data movement mechanism.
A company needs to save the results from a medical trial to an Amazon S3 repository. The repository must allow a few scientists to add new files and must restrict all other users to read-only access. No users can have the ability to modify or delete any files in the repository. The company must keep every file in the repository for a minimum of 1 year after its creation date.Which solution will meet these requirements?
Answer(s): B
S3 Object Lock in compliance mode with a retention period of 365 days ensures immutability for 1 year after creation, meeting the read-only requirement for most users and preventing deletion or modification. Compliance mode enforces write-once-read-many behavior for all objects, regardless of IAM, protecting against both user and account-level changes.A) Governance mode allows users with special permissions to override, which fails the no-modification requirement.C) IAM role + bucket policy can block deletes but does not guarantee immutability or prevent override without Object Lock.D) Lambda hash tracking does not enforce immutability and cannot prevent deletions or modifications.
A large media company hosts a web application on AWS. The company wants to start caching confidential media files so that users around the world will have reliable access to the files. The content is stored in Amazon S3 buckets. The company must deliver the content quickly, regardless of where the requests originate geographically.Which solution will meet these requirements?
Answer(s): C
A) CloudFront edge servers cache and deliver S3-stored media content from edge locations globally, reducing latency for users worldwide, meeting the requirement for fast, geographically distributed access.B) Global Accelerator optimizes global application availability and performance for IP endpoints, but it does not cache or serve S3 content from edge locations.C) CloudFront is a CDN that caches S3 content at edge locations, providing low-latency delivery worldwide.D) SQS is a queuing service for decoupled workflows and does not provide content caching or geographic acceleration.
A company produces batch data that comes from different databases. The company also produces live stream data from network sensors and application APIs. The company needs to consolidate all the data into one place for business analytics. The company needs to process the incoming data and then stage the data in different Amazon S3 buckets. Teams will later run one-time queries and import the data into a business intelligence tool to show key performance indicators (KPIs).Which combination of steps will meet these requirements with the LEAST operational overhead? (Choose two.)
Answer(s): A,E
The correct answer is A and E because they provide serverless, low-management data analytics with centralized storage in S3 and efficient querying/visualization. A) Athena enables ad-hoc, one-time queries directly on S3 data, and QuickSight creates KPI dashboards without moving data. E) Lake Formation blueprints simplify data discovery and ingestion, Glue crawlers catalog and ETL into S3 in Apache Parquet, enabling cost-effective, query-optimized storage for analytics. B is higher overhead with Kinesis Data Analytics for ad-hoc queries and doesn’t directly optimize storage formats. C uses custom ETL with Redshift, increasing maintenance. D loads to OpenSearch clusters, not ideal for BI KPIs.
A company stores data in an Amazon Aurora PostgreSQL DB cluster. The company must store all the data for 5 years and must delete all the data after 5 years. The company also must indefinitely keep audit logs of actions that are performed within the database. Currently, the company has automated backups configured for Aurora.Which combination of steps should a solutions architect take to meet these requirements? (Choose two.)
Answer(s): D,E
The correct combination ensures long-term audit logs and fixed 5-year data retention using AWS-native controls. D) Configuring an Amazon CloudWatch Logs export for the DB cluster preserves database activity logs indefinitely in CloudWatch Logs, meeting audit retention. E) Using AWS Backup to take and retain backups for 5 years enforces immutable, long-term storage beyond automated DB backups and provides centralized lifecycle management. A) Manual snapshots are not automated retention; B) Lifecycle policy for automated backups is not a defined feature; C) Automated backup retention only applies to retention period, not indefinite audit logging.
A solutions architect is optimizing a website for an upcoming musical event. Videos of the performances will be streamed in real time and then will be available on demand. The event is expected to attract a global online audience.Which service will improve the performance of both the real-time and on-demand streaming?
Answer(s): A
CloudFront leverages a global CDN to cache and deliver both real-time (live) streaming with low latency and on-demand video from edge locations, improving performance for a worldwide audience. It integrates with streaming services and supports adaptive bitrate for live feeds and on-demand content delivery.A) CloudFront: Correct — global CDN reduces latency for both live and on-demand video.B) AWS Global Accelerator: Optimizes path to applications but not specifically content caching for media; not ideal for streaming media delivery at scale.C) Route 53: DNS routing, not content delivery or caching for media streams.D) S3 Transfer Acceleration: Accelerates uploads/downloads to S3, not optimized streaming delivery.
A company is running a publicly accessible serverless application that uses Amazon API Gateway and AWS Lambda. The application’s traffic recently spiked due to fraudulent requests from botnets.Which steps should a solutions architect take to block requests from unauthorized users? (Choose two.)
Answer(s): A,C
A) Implementing a usage plan with an API key helps restrict access to genuine users and controls quota for the public API, reducing exposure to unauthorized requests.C) An AWS WAF rule targets malicious traffic (e.g., botnets) at the API Gateway level and can block or rate-limit such requests, mitigating fraudulent traffic before Lambda invocation.B) Lambda logic to ignore fraudulent IPs is ineffective, as IP spoofing and botnets can evade simple checks and adds processing cost; defense should occur at edge/security layer.D) Converting to a private API with DNS redirection would disrupt legitimate users and is not suitable for a public-facing service requiring controlled access.E) Creating an IAM role per user is impractical for public APIs and does not scale; API Gateway IAM is not intended for per-user authentication in this context.
An ecommerce company hosts its analytics application in the AWS Cloud. The application generates about 300 MB of data each month. The data is stored in JSON format. The company is evaluating a disaster recovery solution to back up the data. The data must be accessible in milliseconds if it is needed, and the data must be kept for 30 days.Which solution meets these requirements MOST cost-effectively?
The correct answer is C) Amazon S3 Standard. It provides durable object storage with millisecond access and suits 30-day retention for JSON data at the lowest cost for frequently accessed backups. S3 Standard offers high durability and availability, meeting DR needs without retrieval delays or extra restore steps.A) Amazon OpenSearch Service is a search/analytics service, not a cost-effective backup store for 30 days with millisecond access. It adds unnecessary compute and indexing costs.B) Amazon S3 Glacier is archival storage with retrieval latency ranging from minutes to hours, not millisecond access, and is unsuitable for frequent access.D) Amazon RDS for PostgreSQL is a relational database service, not a blob storage solution for backups, incurring higher cost and complexity for this use case.

i failed the cisa exam today. but i have found all the questions that were on the exam to be on this site.
in question 272 the right answer states that an autonomous acces point is "configured and managed by the wlc" but this is not what i have learned in my ccna course. is this a mistake? i understand that lightweight aps are managed by wlc while autonomous work as standalones on the wlan.

please add this exam
please upoad
has anyone recently attended safe 6.0 certification? is it the samq question from here.
expository experience
52 should be b&c. controller failure has nothing to do with this type of issue. degraded state tells us its a raid issue, and if the os is missing then the bootable device isnt found. the only other consideration could be data loss but thats somewhat broad whereas b&c show understanding of the specific issues the question is asking about.
great help!!!
very useful tools
looks a good platform to prepare az-104
want to pass the exam
