An Infrastructure Administrator is troubleshooting an ESXi host that has disconnected from vCenter. The administrator suspects the syslog service on the host is overwhelmed due to a new NSX distributed firewall logging rule that was recently enabled.
According to the knowledge base (KB 370670), which log file is the most likely source of the excessive logging rate in this scenario, and which log file would contain the evidence of dropped syslog messages? (Choose 2.)
- A . The evidence of dropped messages is in `vmkernel.log`.
- B . The evidence of dropped messages is in `vobd.log`.
- C . The source of excessive logging is `dfwpktlogs.log`.
- D . The source of excessive logging is `hostd.log`.
- E . The source of excessive logging is `vmkwarning.log`.
- F . The evidence of dropped messages is in `syslog.log`.
If vCenter Server is unavailable in a workload domain, what impact does it have?
- A . SDDC Manager becomes unavailable
- B . Only HCX stops functioning
- C . VM management is disrupted
- D . NSX Edge cluster is deleted
A Cloud Administrator needs to deploy the VMware Identity Broker (VIDB) to enable SSO for a newly deployed VCF 9.0 fleet.
From which interface is the VIDB appliance deployed as a day-2 operation?
- A . From the VCF Operations UI
- B . From the SDDC Manager UI
- C . From the vCenter Server vSphere Client
- D . From the VCF Installer appliance UI
A Network Administrator is troubleshooting an issue where a virtual machine on an NSX overlay segment can reach other VMs on the same segment, but cannot reach its default gateway, which is the IP address of the Segment’s interface on the Tier-1 Gateway. The administrator has verified the VM’s IP configuration is correct.
Which of the following are potential causes for this specific connectivity failure? (Select all that apply.)
- A . The NSX Edge cluster hosting the Tier-1 gateway services is down.
- B . The Tier-1 Gateway has no uplink connection to a Tier-0 Gateway.
- C . The ESXi host’s Geneve TEP (Tunnel End Point) vmkernel adapter is misconfigured or cannot reach other TEPs.
- D . A Distributed Firewall rule is blocking the traffic to the gateway IP.
- E . The segment is not connected to any Tier-1 Gateway.
Which certificate type is replaced during a VCF certificate renewal task?
- A . Only NSX certificate
- B . Only vCenter certificate
- C . All management component certificates
- D . Only ESXi certificates
A Platform Engineer is troubleshooting an issue where a developer is unable to create a new subnet inside an NSX VPC. The developer is receiving an error message indicating an overlapping address space.
The engineer reviews the existing subnets within the VPC:
VPC Name: ‘dev-vpc-01’
Address Blocks (from Provider): 172.16.0.0/16
Existing Subnets:
– Name: web-subnet, CIDR: 172.16.10.0/24
– Name: app-subnet, CIDR: 172.16.20.0/24
The developer is attempting to create a new subnet with the CIDR `172.16.10.128/25`.
Why is this operation failing?
- A . The VPC has reached its maximum allowed number of subnets.
- B . The new subnet CIDR `172.16.10.128/25` overlaps with the existing `web-subnet` CIDR `172.16.10.0/24`.
- C . The developer does not have permission to create subnets.
- D . The new subnet CIDR is outside the provider-allocated address block.
An Automation Engineer is investigating a VCF Automation deployment that fails during the final stages of provisioning. The virtual machine is cloned successfully, but the deployment fails after several minutes.
The deployment history shows the following error message:
Phase: Customization
Status: FAILED
Message: Timed out waiting for guest OS customization to complete. The VM may not have acquired an IP address or the agent failed to start.
What are the most likely causes of this guest customization timeout? (Select all that apply.)
- A . The Cloud Zone for the deployment has no available compute resources.
- B . A firewall is blocking communication between the newly deployed VM and the VCF Automation appliance or its proxies.
- C . The VM template used for the deployment does not have a recent version of VMware Tools installed and running.
- D . The Network Profile used for the deployment has an incorrect gateway or DNS server configuration, preventing the VM from reaching the network.
- E . The blueprint is requesting a storage tag that does not exist.
A VCF Support Engineer is troubleshooting an issue where new VMs on an overlay segment are unable to obtain an IP address. The Network Administrator states that a local NSX DHCP server has been configured on the segment’s Tier-1 Gateway.
The engineer inspects the configuration of the segment in NSX Manager and finds the following:
Segment: ‘Web-Tier-Segment’
Connected Gateway: ‘T1-App-Dev’
Subnets: 192.168.50.1/24
DHCP Config:
Type: DHCP Relay
Relay Server: 10.10.10.10
Based on this configuration, what is the cause of the issue?
- A . The DHCP IP pool on the local server is exhausted.
- B . The segment is not connected to a gateway.
- C . The DHCP service has not been enabled on the NSX Edge Cluster.
- D . The segment is configured to use a DHCP Relay service instead of the local DHCP server on the gateway.
A junior administrator is tasked with collecting a log bundle from a vCenter Server in a VCF environment to troubleshoot a performance issue. Instead of using the Log Assist feature in VCF Operations, the administrator logs directly into the vCenter Server Appliance Management Interface (VAMI) to generate the bundle.
What is a significant disadvantage of this manual approach compared to using the centralized Log Assist feature?
- A . The VAMI cannot generate a complete vCenter log bundle.
- B . The manually generated bundle will not contain performance metrics.
- C . The administrator must first place the vCenter Server into maintenance mode.
- D . The bundle must be manually downloaded from the VAMI and then manually uploaded to a Broadcom SR.
An Infrastructure Administrator needs to add three new, commissioned hosts to an existing cluster in a VI Workload Domain.
Where in the SDDC Manager UI is the "Add Hosts" workflow initiated for a specific cluster?
- A . Under Inventory > Hosts, by selecting the commissioned hosts and clicking "Add to Cluster".
- B . Under Inventory > Workload Domains, by selecting the domain and then navigating to the specific cluster to find the "Add Hosts" action.
- C . Under Administration > Licensing > Hosts.
- D . Under Lifecycle Management > Hosts > Add Hosts.
