Scenario: A website is experiencing a sudden surge in traffic due to a viral post. How can Cloud CDN help in this situation?
- It caches content at edge locations to reduce load on the origin server
- It increases the compute power of the origin server
- It scales the database automatically to handle more queries
- It blocks excessive traffic to prevent server overload
Cloud CDN is effective in managing traffic surges by distributing and caching content, thereby reducing the load on the origin server and maintaining performance during high traffic periods.
Scenario: A company requires high availability for its database server running on Google Cloud. Which feature of Persistent Disk should they leverage to ensure data redundancy and fault tolerance?
- Regional Persistent Disk
- Zonal Persistent Disk
- Local SSD
- Cloud Storage
Understanding the different types of Persistent Disk options and their capabilities is crucial for architecting highly available systems on Google Cloud. Leveraging Regional Persistent Disk ensures data redundancy and fault tolerance, which are essential for maintaining high availability for critical workloads like databases.
Google Dataflow is a managed _______ processing service.
- Data
- Compute
- Storage
- Networking
Understanding that Google Dataflow is a managed data processing service is essential for users to leverage its capabilities effectively.
In the context of Google Cloud's Network Service Tiers, what does the term "optimized" imply?
- Tailored for specific use cases, balancing performance and cost efficiency.
- Geared towards maximum performance, regardless of cost.
- Designed for minimum latency, regardless of cost.
- Tailored for maximum cost efficiency, regardless of performance.
Understanding what the term "optimized" implies in the context of Google Cloud's Network Service Tiers is essential for selecting the appropriate tier that aligns with application requirements and budget constraints. By choosing the optimized tier, organizations can achieve the desired balance between performance and cost efficiency.
Cloud CDN reduces _______ by caching content closer to users.
- Latency
- Costs
- Complexity
- Storage
Cloud CDN, or Content Delivery Network, is designed to reduce latency by storing copies of content closer to the end users. This geographical proximity decreases the time it takes for data to travel, leading to faster content delivery.
Scenario: A healthcare organization needs to ensure continuous availability of its patient portal application. How can Cloud Load Balancing be configured to meet this requirement?
- Setting up health checks for backend instances
- Using a single backend instance
- Enabling SSL termination at the load balancer
- Implementing session stickiness
To ensure continuous availability, Cloud Load Balancing should be configured with health checks to monitor the health of backend instances and remove unhealthy ones from the pool, thus maintaining reliable and uninterrupted access to the application.
Which metric is commonly used to determine when to scale up or down in autoscaling?
- CPU Utilization
- Disk Space Usage
- Memory Usage
- Network Latency
Understanding which metrics are commonly used for autoscaling helps administrators configure effective scaling policies that respond appropriately to changes in workload demand, ensuring optimal performance and resource utilization.
GKE provides built-in _______ for monitoring and logging containerized applications.
- Monitoring and Logging
- CI/CD Pipelines
- Security Policies
- Load Balancing
Understanding the built-in monitoring and logging capabilities of Google Kubernetes Engine is essential for effectively monitoring and troubleshooting containerized applications deployed on GKE clusters.
