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.
A company has just deployed a new cloud-based application. The users interact with the application through a web browser, but they report that sometimes the application is slow. While the front end appears fine, where would you start investigating for potential issues?
- Backend server performance tuning
- Browser cache analysis
- Database optimization
- Network latency check
In this scenario, the slowdown issue is likely in the backend. Starting with backend server performance tuning is a key step to address the problem.
In a cloud scenario, if an attacker gains control over a user's access credentials, it can lead to ________.
- Account Lockout
- Data Loss
- Resource Optimization
- Unauthorized Access
In a cloud scenario, if an attacker gains control over a user's access credentials, it can lead to "Unauthorized Access." This access can be used to compromise data, resources, or even perform malicious actions within the cloud environment.
Which of the following can be a preventive measure against data breaches caused by insider threats?
- Ignoring insider threats
- Increasing firewall strength
- Reducing the number of external threats
- Regular security training for employees
Preventive measures against insider threats include regular security training for employees to make them aware of security best practices and the risks associated with insider threats. Education can help reduce the likelihood of insider incidents.
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.
