Automatic Scaling and Monitoring

What is the role of a Hypervisor in cloud computing?

• To manage the physical network infrastructure of a cloud service.

• To provide secure access to cloud resources for authorized users.

• To create virtual server instances from a physical server.

• To analyze user data and identify trends for improving cloud performance.

What is an Auto Scaling group in Amazon EC2 Auto Scaling?

• A collection of EC2 instances that are treated as a logical grouping for automatic scaling and management.

• A software program that monitors the performance of cloud applications and identifies potential issues.

• A data storage platform for storing user data and ensuring its security.

• A network virtualization tool that enables the creation of complex cloud service architectures.

How does Amazon EC2 Auto Scaling ensure the availability of cloud applications during scaling events?

• By carefully managing the deployment of new EC2 instances to avoid disrupting existing services.

• By providing a secure platform for storing user data and preventing unauthorized access.

• By monitoring the health of EC2 instances and triggering alarms in case of issues.

• By analyzing user feedback and identifying performance issues based on user experience.

Which of the following is NOT a common type of Resource Cluster?

• Server Cluster

• Database Cluster

• Storage Cluster

• Large Dataset Cluster

What is the difference between scaling out and scaling in in Amazon EC2 Auto Scaling?

• Scaling out involves launching additional instances, while scaling in involves terminating existing instances.

• Scaling out involves deploying new cloud services, while scaling in involves removing existing services.

• Scaling out involves increasing the storage capacity of a cloud service, while scaling in involves reducing storage capacity.

• Scaling out involves improving the security of a cloud service, while scaling in involves reducing security measures.

Which of the following is NOT a scaling option provided by Amazon EC2 Auto Scaling?

• Manual Scaling

• Scheduled Scaling

• Dynamic Scaling

• Predictive Scaling

What is the role of Amazon CloudWatch in dynamic scaling with Amazon EC2 Auto Scaling?

• It provides a secure platform for storing user data and ensuring its security.

• It enables the creation of complex cloud service architectures through network virtualization.

• It collects metrics about EC2 instances and other AWS resources, providing data for scaling policies.

• It automates the deployment of cloud services and applications based on predefined rules.

What is the primary function of a State Management Database in cloud computing?

• To store user login credentials and access permissions.

• To provide persistent storage for long-running cloud services.

• To temporarily store state data for software programs, reducing memory usage.

• To monitor the health of cloud resources and trigger alarms in case of issues.

In an Active-Active Failover System, what happens when a failure is detected?

• The failed instance is automatically shut down and removed from the system.

• The workload is immediately shifted to the standby instance.

• The failed instance is removed from the load balancing scheduler.

• The entire system is temporarily shut down until the issue is resolved.

What is the primary function of Amazon CloudWatch in cloud computing?

• To store and manage user data for cloud applications.

• To provide a secure platform for user authentication and access control.

• To monitor AWS resources and applications, collect metrics, and trigger alarms.

• To automate the deployment of cloud services and applications based on predefined rules.
