Question 1 of 30
A data center experiences a network outage affecting multiple virtual machines (VMs) hosted on a Cisco Unified Computing System (UCS). The network team identifies that the issue is related to a misconfigured VLAN that is preventing communication between the VMs and the external network. After correcting the VLAN configuration, the team needs to verify the connectivity of the VMs. Which of the following steps should be taken first to ensure that the VMs can communicate with the external network?
Check the VLAN assignment on the virtual network interface cards (vNICs) of the VMs.
Restart the VMs to apply the new VLAN configuration.
Verify the physical switch port configuration connected to the UCS.
Update the UCS firmware to the latest version.
