A media analytics organization stores daily application log files in a Google Cloud Storage bucket. Due to data compliance and cost-optimization policies, the organization requires log files to be automatically deleted once they reach 30 days of age, without requiring manual intervention or custom maintenance scripts. Which Cloud Storage feature should you configure to satisfy this requirement?

Configure an Object Lifecycle Management rule with an age condition to delete the objects.: ### **What Object Lifecycle Management is:** **Object Lifecycle Management** is a built-in Cloud Storage capability that allows administrators to define automated rules assigned to a bucket. Each rule contains a set of **conditions** (such as object age, creation date, storage class, or live state) and an **action** (such as deleting the object or transitioning it to a colder storage class). ### **How it meets the requirements:** - **Automated deletion (✓):** Object Lifecycle Management rules run automatically in the background on Google Cloud infrastructure without requiring scheduled cron jobs, external scripts, or manual triggers. - **Age-based criteria (✓):** Setting an **Age** condition of `30` days targets all objects that have reached 30 days since their creation timestamp. - **Cost efficiency & compliance (✓):** Automatically purging outdated logs ensures that storage expenses are minimized and compliance retention schedules are strictly adhered to. ### **Key capabilities of Object Lifecycle Management:** - **Lifecycle Actions:** Supports `Delete`, `SetStorageClass` (transitioning to Nearline, Coldline, or Archive), and `AbortIncompleteMultipartUpload`. - **Lifecycle Conditions:** Allows filtering by `Age` (in days), `CreatedBefore`, `CustomTimeBefore`, `IsLive`, `MatchesStorageClass`, and `NumberOfNewerVersions`. - **Zero Compute Overhead:** Google Cloud inspects and applies lifecycle rules asynchronously without consuming your project compute resources or incurring runtime VM costs. - **Granular Prefix/Suffix Matching:** Rules can be scoped to specific directory prefixes or file extensions within the bucket. ### **Why this is optimal:** Object Lifecycle Management is the native, fully managed solution designed specifically for routine data aging and automatic deletion policies in Cloud Storage. It removes operational complexity while guaranteeing consistent policy enforcement.

A data engineering team at a retail organization uploads daily transaction log files into a Google Cloud Storage bucket. To minimize storage costs and comply with internal data retention guidelines, the team needs to automatically delete log files once they are 30 days old. Which method should the team use to configure and manage automated object deletion on the Cloud Storage bucket?

Configure rules to delete objects after a specified period to automatically remove unnecessary data and reduce storage expenses (e.g., BigQuery, Cloud Storage)

A data engineering team manages a daily-partitioned BigQuery table named telemetry_logs. To optimize storage costs and adhere to data retention guidelines, the team needs to ensure that individual partitions are automatically deleted 60 days after their partition date, while keeping the table definition and more recent partitions intact. Which SQL statement should the team execute to configure this automated retention rule?

An enterprise is storing sensitive customer analytics datasets across Google Cloud storage and data services, such as BigQuery and Cloud Storage. While Google Cloud encrypts all data at rest by default, the company's regulatory compliance mandate requires the security team to maintain direct control over key rotation schedules, audit key usage, and immediately revoke access to data by disabling keys if a security incident occurs. Which encryption strategy should the organization implement to meet these compliance requirements?

A financial analytics company needs to modernize its data pipeline to process high-volume, real-time streaming transaction records. The solution must support continuous stream ingestion, execute in-flight transformations with sub-second latency, scale automatically during unpredictable traffic spikes, and load the enriched output into BigQuery without requiring manual cluster management. Which Google Cloud service should the company select to meet these business and technical requirements?

A logistics enterprise manages a fleet of delivery vehicles equipped with IoT temperature and GPS sensors. The company needs an architecture that satisfies the following requirements: Ingest sensor readings continuously in real time as events occur across thousands of vehicles Make sensor data immediately queryable for analytical dashboards and anomaly detection Decouple device publishers from consumers so new analytical tools can be attached later without modifying the vehicle systems Which architectural pattern and service combination should the company implement?

Your enterprise operates dozens of microservices deployed across multiple Google Cloud projects segregated by environment and department. You need to establish a centralized observability strategy with the following requirements: Site Reliability Engineers (SREs) must view aggregated compute metrics and custom dashboards across all production projects from a single interface. Metric-threshold alerting policies must be created centrally and evaluate time-series data across all monitored projects. SREs should be able to configure alerts and dashboards centrally without requiring administrative permissions in the individual monitored projects. Which architecture should you implement to satisfy these requirements?
