Cloud+ V3 Performance Troubleshooting Assessment

1. Your cloud application experiences intermittent timeouts during peak traffic. Which bottleneck should you investigate first?

Application code efficiency and database query performance

Physical server color

User device specifications

Cloud provider logo

2. Your cloud application's API response time increases after deploying a new version. What troubleshooting approach is most effective?

Compare API metrics before and after deployment; review code changes and dependencies

Immediately rollback without investigation

Blame the cloud provider

Increase marketing budget

3. When investigating cloud storage performance, what indicates a potential storage tier mismatch?

Frequent data access patterns not aligned with storage class

Storage vendor's company name

Color of storage device lights

Cloud provider's employee count

4. A cloud load balancer health check is failing for all backend instances. What is the most efficient first step?

Check health check configuration, port, and protocol settings

Replace all servers

Delete the load balancer

Change the cloud provider

5. Your DNS resolution for cloud services intermittently fails. Which component should you troubleshoot?

Cloud provider's DNS servers and resolver configuration

User's monitor brightness

Physical server case material

Cloud provider's building address

6. When cloud application response time degrades gradually over days, what is a common root cause?

Memory leaks or resource exhaustion

User mood changes

Cloud provider paint color

Keyboard manufacturer defects

7. A database replica in your cloud environment is lagging behind the primary. What metric indicates replication lag?

Backup file size

Replication delay in seconds or transactions behind

Total user count

Storage encryption status

8. Your cloud infrastructure monitoring shows periodic CPU spikes every hour at the same time. What is the likely cause?

Scheduled maintenance tasks or batch jobs

Random hardware failure

Cloud provider attack

User time zone differences

9. When troubleshooting cloud network connectivity, a traceroute command shows high latency at a specific hop. What does this indicate?

The destination server is offline

A bottleneck or congestion exists at that network node

Your local network is misconfigured

The cloud provider is bankrupt

10. A virtual machine's disk I/O utilization is consistently above 95%. What immediate action reduces performance degradation?

Enable disk caching and optimize I/O patterns

Delete all user files

Disable network connectivity

Remove all security patches

11. When a virtual machine in your cloud environment exhibits high CPU utilization consistently above 90%, what is the first diagnostic step you should take?

Immediately add more vCPUs to the instance

Check running processes and identify resource-intensive applications

Migrate the VM to a different host

Reboot the virtual machine

12. When packet loss occurs between your on-premises datacenter and cloud infrastructure, what metric should you monitor?

Disk space utilization

Network packet loss percentage and retransmission rates

Memory usage trends

User session count

13. A cloud storage service returns 403 Forbidden errors when users attempt file access. What is the primary troubleshooting area?

Network bandwidth limitations

Access control lists and IAM permissions

Storage device hardware failure

Cloud provider maintenance window

14. An autoscaling group in your cloud environment is not scaling up despite high CPU load. What should you verify?

Autoscaling policy thresholds and CloudWatch alarm configuration

Physical server capacity

User login credentials

Database backup status

15. Your cloud load balancer shows uneven traffic distribution across backend instances. What is the most likely cause?

Misconfigured load balancing algorithm or unhealthy backend instances

Insufficient internet bandwidth

Expired SSL certificates

Incorrect firewall rules

16. When troubleshooting cloud application latency, which tool provides end-to-end request tracing across microservices?

Ping utility

Distributed tracing and APM tools

IPCONFIG command

File system monitoring

17. A containerized application in your cloud cluster shows memory pressure warnings. What is the primary concern?

Containers will be evicted and rescheduled

The container registry is full

Network bandwidth is limited

Storage encryption is enabled

18. Your cloud database is experiencing connection pool exhaustion during peak hours. What should you check first?

Database version compatibility

Number of concurrent connections and query execution time

Database backup schedule

Physical server hardware specifications

19. Which cloud storage metric would you investigate if users report slow file read operations from cloud storage?

Storage capacity utilization percentage

Input/output operations per second (IOPS) and throughput

Total storage cost

Number of concurrent users

20. A user reports slow application response times. Network latency measurements show 150ms round-trip time between client and cloud server. Is this acceptable for typical cloud applications?

True

False
