Cloud+ Hybrid Cloud Connectivity Troubleshooting

1. You discover that cloud-to-on-premises replication is failing. Which log file should you check first?

Replication service logs on the source and destination

Operating system event viewer only

Cloud provider's billing logs

Application installation logs

2. A hybrid cloud disaster recovery test shows data inconsistency between on-premises and cloud backups. What should you verify?

Replication synchronization settings, timestamps, and backup integrity

Both environments are in the same time zone

Cloud provider's backup retention policy

Local storage device serial numbers

3. Your hybrid cloud setup requires users to re-authenticate every few minutes. What is the most likely cause?

Session timeout settings or token expiration too short

Cloud provider is performing maintenance

Local network has too many users

Browser cache is full

4. A hybrid cloud environment shows intermittent connection drops. Which diagnostic command would reveal packet loss statistics?

Ping -c 100 (or ping -n 100 on Windows) with packet count analysis

Ipconfig /all

Dir command

Tasklist

5. When troubleshooting a hybrid cloud integration, you find that API calls are returning 503 errors. What should you check immediately?

Cloud service availability status and API gateway logs

Local system clock synchronization

Your internet service provider's uptime

The on-premises application's source code

6. Your hybrid cloud load balancer is not distributing traffic evenly between on-premises and cloud servers. What is the most likely issue?

Health check configuration or server weight settings

Cloud provider's network throttling

Incorrect DNS CNAME record

Local firewall blocking return traffic

7. A hybrid cloud application cannot sync data between on-premises and cloud databases. What should you verify first?

Network connectivity, firewall rules, and database replication settings

Both databases have identical schemas

Cloud provider supports your database version

Local server has at least 16 GB RAM

8. An SSL/TLS certificate on the hybrid cloud gateway expires, breaking connectivity. What is the immediate fix?

Install a new valid certificate and restart the gateway service

Disable SSL/TLS temporarily and use HTTP

Request a certificate extension from the provider

Switch to a different cloud provider

9. Your hybrid cloud backup fails with a timeout error. Which component should you troubleshoot first?

Network connectivity and bandwidth between environments

Cloud provider's backup service availability

Local backup software version compatibility

Database backup window schedule

10. A user reports that uploading files to hybrid cloud storage is extremely slow. What is the most likely culprit?

Inadequate WAN bandwidth or high utilization

Local antivirus scanning every upload

Cloud provider pricing tier

File compression settings

11. A user cannot access a cloud application from an on-premises network. Which tool would you use first to verify network connectivity between the two environments?

Tracert/traceroute

Nslookup

Ipconfig

Netstat

12. A hybrid cloud deployment shows high packet loss on the WAN connection. Which metric would you monitor to identify the bottleneck?

Jitter and retransmission rate

CPU utilization percentage

Database query response time

Cloud storage access logs

13. When performing hybrid cloud failover, an application times out connecting to the backup cloud instance. What should you verify first?

DNS records point to the backup instance

The primary database is fully replicated

SSL certificates are installed on both instances

Load balancer health checks are disabled

14. A cloud storage bucket is inaccessible from on-premises due to access denied errors. What is the primary cause?

Bucket policy or IAM role permissions misconfiguration

Cloud provider's data center offline

Local network adapter failure

Incorrect subnet mask on server

15. Your on-premises firewall is blocking cloud-bound traffic on port 443. What is the correct troubleshooting step?

Disable the firewall entirely

Add an outbound rule allowing port 443 to cloud provider IPs

Switch to HTTP instead of HTTPS

Reconfigure the cloud security group

16. A hybrid cloud application experiences DNS resolution failures intermittently. Which configuration would resolve this issue?

Implement a redundant DNS server with conditional forwarders

Increase the cloud instance RAM

Reduce the TTL value to 10 seconds

Change the cloud storage class

17. When troubleshooting a VPN tunnel between on-premises and cloud, you notice the tunnel is up but traffic is not flowing. What should you check first?

VPN encryption algorithm

Routing tables and static routes

Cloud provider's SLA

Physical cable connections

18. An authentication failure occurs when connecting to a cloud service via a hybrid setup. Which credential or configuration issue is most common?

Expired API key or token

Incorrect cloud region setting

Misconfigured load balancer

Insufficient disk space on server

19. Your hybrid cloud setup experiences intermittent latency spikes. What is the most likely cause if latency increases during business hours?

Bandwidth saturation on the WAN link

DNS resolution failure

Firewall rule misconfiguration

Cloud storage bucket permissions
