- Question 1
While implementing a monitoring strategy for a geographically distributed microservices architecture, which approach is MOST likely to be preferred?
- ✓
Centralized monitoring with all data collected and analyzed at a single location
Correct - B
Utilizing synthetic monitoring tools only, as they don't require infrastructure agents
- C
A combination of centralized and distributed monitoring with selective data collection
- D
Distributed monitoring with agents collecting data on individual microservices
- ✓
- Question 2
A significant increase in database connection errors disrupts your application's functionality. How can you utilize observability data to diagnose the root cause beyond simply identifying the error messages?
- ✓
Restart the database server to potentially clear temporary connection issues.
Correct - B
Analyze database logs for specific error messages related to the connection failures
- C
Correlate application metrics (e.g., request volume) with database connection errors to identify potential causes like sudden traffic spikes
- D
Increase the connection pool size for the database to handle a higher volume of connections
- ✓
- Question 3
You are the SRE for a social media platform experiencing a sudden increase in error rates for image uploads. The platform utilizes various services for image processing, storage, and content delivery. While investigating the image upload issue, you observe spikes in error rates for the image processing service alongside increased latency for the content delivery network (CDN). Identify the utilization of proper observability practice for effectively identifying the root cause of the issue.
- ✓
Focusing solely on troubleshooting the image processing service, neglecting potential dependencies on other components
Correct - B
Correlating metrics from the image processing service with CDN latency data to identify potential bottlenecks or resource limitations causing both issues
- C
Restarting all affected services to potentially clear temporary glitches, a reactive and potentially disruptive approach
- D
Waiting for the user reports to describe the specific nature of the upload errors, a user-dependent approach
- ✓
- Question 4
Your team is responsible for a large e-commerce platform experiencing abandoned shopping carts during the checkout process. How can you leverage observability data to understand the user journey and identify potential drop-off points?
- ✓
Analyze user behavior data and application performance metrics throughout the checkout flow to identify slowdowns or confusing steps
Correct - B
Focus solely on monitoring application error logs related to the checkout functionality
- C
Conduct A/B testing on different checkout page designs to determine user preferences
- D
Increase the logging level for the shopping cart functionality to capture more detailed information
- ✓
- Question 5
Utilizing distributed tracing, you discover that a specific API call within the product page generation microservice is causing significant delays. This API call retrieves product data from a legacy database system. Which of the following courses of action will be the MOST appropriate to address the bottleneck and improve performance while the sales event is ongoing?
- ✓
Increase the connection pool size for the database to handle more concurrent requests from the microservice
Correct - B
Optimize the specific API call within the microservice to potentially reduce the amount of data retrieved from the database or utilize caching for frequently accessed product data
- C
Temporarily disable the problematic API call within the microservice, potentially impacting product information displayed on the page
- D
Migrate the product data from the legacy database to a more scalable NoSQL database solution
- ✓
- Question 6
