Infrastructure as Code (IaC) is a practice that allows you to manage and provision IT infrastructure using code and automation tools. It impacts monitoring by enabling consistent and repeatable environments, making it easier to implement monitoring solutions, automate alerts, and ensure that monitoring configurations are version-controlled and easily reproducible across different environments.

Right Answer:

3. Disk I/O
4. Network Traffic
5. Disk Space Utilization
6. System Load Average
7. Process Count
8. Error Rates
9. Temperature and Power Usage
10. Application Performance Metrics

Right Answer:

To set up an alerting escalation policy, follow these steps:

1. **Define Alert Criteria**: Identify the conditions that trigger alerts (e.g., CPU usage, downtime).
2. **Set Alert Severity Levels**: Classify alerts by severity (e.g., critical, warning, info).
3. **Establish Notification Channels**: Decide how alerts will be communicated (e.g., email, SMS, chat).
4. **Create Escalation Paths**: Outline who gets notified first and who to escalate to if the issue isn’t resolved within a set timeframe.
5. **Set Response Timeframes**: Define how quickly each level of escalation should respond.
6. **Document the Process**: Ensure all team members understand the escalation policy.
7. **Test the Policy**: Regularly test the alerting system to ensure it works as intended.
8. **Review and Adjust**: Periodically review the policy for effectiveness and make adjustments as necessary.

SNMP, or Simple Network Management Protocol, is a protocol used for managing and monitoring network devices. It allows network administrators to collect and organize information about devices such as routers, switches, and servers, and to manage their performance and configuration. SNMP operates by using a manager to request data from agents on the devices, which respond with the requested information, enabling effective network monitoring and management.

Right Answer:

To monitor cloud infrastructure in AWS, Azure, or GCP, you can use the following tools:

– **AWS**: Amazon CloudWatch for metrics and logs, AWS CloudTrail for API activity, and AWS Config for resource configuration tracking.
– **Azure**: Azure Monitor for performance and health metrics, Azure Log Analytics for log data, and Azure Security Center for security monitoring.
– **GCP**: Google Cloud Monitoring for resource metrics, Google Cloud Logging for log management, and Google Cloud Operations Suite for overall monitoring and management.

Additionally, third-party tools like Datadog, New Relic, or Prometheus can also be integrated for comprehensive monitoring across multiple cloud platforms.
