VCP-VMC 2024 Question 204
Select 3A cloud administrator is troubleshooting a workload running in VMware Cloud on AWS. The application running on the workload is experiencing intermittent connectivity issues. Upon investigation, the administrator notices packet drops between the workload and an on-premises database. Which of the following steps should the administrator take to resolve the issue?
- A
Verify the VPN or Direct Connect link status between the on-premises environment and VMware Cloud on AWS.
- B
Check the firewall rules in VMware Cloud to ensure traffic to the database is allowed.
- C
Increase the memory and CPU resources allocated to the workload.
- D
Review the NSX-T Distributed Firewall logs for any dropped packets.
- E
Migrate the workload to a different VMware Cloud on AWS host to resolve connectivity issues.
Show answer and explanation
Correct answers: A, B, D
Explanation
Intermittent connectivity issues between a workload in VMware Cloud on AWS and an on-premises database can be caused by network-related factors such as link status, firewall rules, or security policies. Verifying the VPN or Direct Connect link status ensures the physical or virtual connection between the two environments is stable. Checking firewall rules ensures that traffic is not being blocked. Reviewing NSX-T Distributed Firewall logs can identify if any security policies are causing packet drops. Increasing resources or migrating the workload will not address network connectivity issues.
- A. Correct.
This is a valid step. Packet drops could be caused by issues with the network link, such as VPN or Direct Connect. Verifying the link status can help identify and resolve connectivity issues.
- B. Correct.
This is a valid step. Misconfigured firewall rules in VMware Cloud could block traffic to the database, causing connectivity issues.
- C. Incorrect.
This is not a valid step. Resource allocation (memory and CPU) primarily affects workload performance, not connectivity issues.
- D. Correct.
This is a valid step. NSX-T Distributed Firewall logs can help identify whether packets are being dropped due to security policies within VMware Cloud.
- E. Incorrect.
This is not a valid step. Migrating the workload to another host does not directly address the underlying connectivity issue between the workload and the on-premises database.
