A healthcare tech startup is working on a wearable device that can predict potential health anomalies in users. They want to use AI to analyze the data but are concerned about patient privacy. What could be a cloud-based solution for this?
- Federated Learning
- Limiting data collection
- Storing all data centrally
- Using a public AI service
Federated Learning is a privacy-preserving technique where AI models are trained across multiple decentralized devices (wearables, in this case) without moving raw data to a central location. It ensures patient privacy while using AI for analysis.
Google Cloud's equivalent to AWS's RDS (Relational Database Service) is ________.
- Bigtable
- CloudSQL
- Datastore
- Firestore
Google Cloud's counterpart to AWS RDS is CloudSQL, which offers managed relational databases like MySQL and PostgreSQL.
Which of the following best describes cloud computing?
- A way to store personal photos and videos
- A method for companies to save on IT operational costs
- A system to play online games
- Delivering computing services over the internet
Cloud computing is about delivering various computing services like storage, databases, servers, networking, software, and more over the internet. While some of the other options may be components or uses of cloud computing, the core idea is the delivery of computing services via the internet.
A company has a legacy application that is tightly coupled with its current database. They want to migrate to the cloud and modernize the application for better scalability and performance. Which migration strategy should they consider?
- Rearchitecting (rebuilding)
- Refactoring (re-architecting)
- Rehosting (lift-and-shift)
- Retiring or Decommissioning
Refactoring, or re-architecting, is the most suitable strategy when migrating to the cloud while modernizing an application. It involves making application changes to optimize for the cloud environment, ensuring scalability and performance.
Which of the following is a primary function of middleware in a cloud computing environment?
- Installing applications
- Load balancing
- Managing user data
- Server hardware maintenance
A primary function of middleware in cloud computing is load balancing, which evenly distributes network traffic to optimize resource utilization.
In a microservices architecture, the pattern that isolates failures and ensures that a failure in one service doesn't impact others is called the ________ pattern.
- Adapter
- Circuit Breaker
- Observer
- Singleton
The Circuit Breaker pattern is used to isolate failures in a microservices architecture. It prevents a single service failure from cascading through the system.
Continuous monitoring in cloud environments is essential for:
- Detecting and mitigating threats
- Ensuring high availability of services
- Monitoring competitors' cloud usage
- Reducing cloud infrastructure costs
Continuous monitoring in the cloud is crucial for detecting and mitigating security threats, ensuring data protection, and maintaining compliance with regulations. It's not primarily about cost reduction or monitoring competitors.
Google Cloud Functions can be triggered by events from which of the following Google Cloud services?
- Google Cloud Bigtable
- Google Cloud Compute Engine
- Google Cloud Pub/Sub
- Google Cloud Storage
Google Cloud Functions can be triggered by events from Google Cloud Pub/Sub, making it easy to build event-driven applications.
In terms of data analytics, what advantage does AWS Redshift provide over traditional databases?
- ACID Compliance and High Throughput
- Columnar Storage and Parallel Processing
- Document Store and Strong Consistency
- Graph Database and Horizontal Scaling
AWS Redshift is designed for data warehousing and analytics, offering columnar storage and parallel processing for improved performance.
In a scenario where there's a tight deadline to exit a data center, which migration approach might be prioritized, even if it doesn't yield immediate cloud optimization benefits?
- Rearchitect (rebuild)
- Refactor (re-architect)
- Rehost (lift and shift)
- Repurchase (buy a new one)
When facing a tight deadline to exit a data center, 'Rehost' (lift and shift) might be prioritized, even if it doesn't yield immediate cloud optimization benefits, as it's the quickest and least disruptive approach.
