A production VM experiences frequent CPU saturation, and DRS suggests migrations to rebalance the cluster.
What is the first step to confirm if CPU resource constraints are valid?
- A. Migrate the VM to a host with fewer VMs
- B. Check the CPU Ready metric in vCenter or vRealize Operations
- C. Increase the VM's CPU limit
- D. Disable HA to see if it affects performance
Answer: B
Explanation:
CPU Ready time is a key metric reflecting how long a VM waits to be scheduled on a physical CPU.
Monitoring this metric helps determine if CPU saturation is the genuine bottleneck before adjusting resource allocations or migrating VMs.
NEW QUESTION # 114
The administrator of a VMware Cloud Foundation environment notices that log data from multiple components, including vSphere, NSX, and vSAN, is not being collected in Aria Operations for Logs.
What two steps should the administrator perform to resolve this issue? (Choose two.)
- A. Reconfigure the log level settings on all vSphere components to ensure detailed logging.
- B. Verify that the Aria Operations for Logs license is still valid and active.
- C. Check the network connectivity between the Aria Operations for Logs server and the VMware Cloud Foundation components.
- D. Ensure that the syslog configuration on each component is pointing to the correct Aria Operations for Logs server.
- E. Increase the storage capacity of the Aria Operations for Logs server to accommodate more log data.
Answer: C,D
Explanation:
If Aria Operations for Logs cannot reach the vSphere, NSX, or vSAN components over the network, no logs will be collected-so validating connectivity (firewalls, routing, DNS) is essential.
Each component's syslog settings must point to the correct Aria Operations for Logs endpoint; if they're misconfigured, logs won't be forwarded.

NEW QUESTION # 118
An administrator is responsible for maintaining a VMware Cloud Foundation (VCF) instance. The administrator has been tasked with scaling the CPU and RAM resources of a virtual machine.
Which three configuration limitations must the administrator consider when completing the task?
(Choose three.)
- A. To remove Memory to a powered on virtual machine, Memory Hot Add must be enabled.
- B. To add vCPUs to a powered on virtual machine CPU Hot Add must be enabled.
- C. To add Memory to a powered on virtual machine, Memory Hot Add must be enabled.
- D. To add vCPUs to a powered down virtual machine, CPU Hot Add must be enabled.
- E. To enable the CPU Hot Add or Memory Hot Add feature, the virtual machine must be powered off.
- F. To enable Memory Hot Add feature, the virtual machine compatibility must be ESXi 7.0 Update 2 or later.
Answer: B,C,E
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
When scaling CPU and RAM for a virtual machine in a VMware Cloud Foundation environment, the administrator must consider these limitations:
To add Memory to a powered on virtual machine, Memory Hot Add must be enabled (A): Without Memory Hot Add, adding memory requires the VM to be powered off.
To add vCPUs to a powered on virtual machine CPU Hot Add must be enabled (C): CPU Hot Add allows additional virtual CPUs to be added while the VM is powered on; otherwise, the VM must be powered off.
To enable the CPU Hot Add or Memory Hot Add feature, the virtual machine must be powered off (F):
These features can only be activated or changed when the VM is not running.
Removing memory while powered on is not supported, and enabling these hot add features does not require the VM to be at a specific hardware compatibility level unless specified by certain new functionalities, but the core requirement is the VM must be powered off to enable the features. Adding vCPUs to a powered off VM does not require CPU Hot Add.
NEW QUESTION # 119

Answer: A
NEW QUESTION # 125
A single VM is unable to communicate with other VMs on the same network. An administrator needs to identify and resolve the network connectivity issue.
What three steps should the administrator follow? (Choose three.)
- A. Restart the VM to reset its network connections.
- B. Verify that the networking within the VMs quest OS is correct.
- C. Verity that the virtual network adapter is present and connected.
- D. Ensure that the Port Group name(s) associated with the VMs network adapter sexists in the vSwitch or VDS and is spelled correctly
- E. Use the ESXi command line to check the status of the VM Kernel adapter.
Answer: B,C,D
Explanation:
Ensuring the guest OS network configuration (IP, subnet mask, gateway) is correct rules out misconfiguration within the VM.
Confirming the virtual NIC is present and connected verifies the VM's link to the virtual switch. Checking that the port group name exists and is correct ensures the VM is attached to the intended network segment.
NEW QUESTION # 126
During a routine maintenance operation, an administrator needs to move a running VM from one host to another without downtime.
Which vSphere feature is used?
- A. vSphere Replication
- B. vMotion

Explanation:
vMotion enables live migration of a powered-on virtual machine from one ESXi host to another without service interruption.
NEW QUESTION # 127
Which ESXi configuration is generally recommended for best performance with iSCSI storage?
- A. Placing the iSCSI traffic on a VLAN shared with production traffic
- B. Using ephemeral port groups for iSCSI connectivity
- C. Single vSwitch with a single NIC for management and iSCSI
- D. Using CHAP authentication and a dedicated iSCSI network
Answer: D
Explanation:
iSCSI best practice includes secure authentication (CHAP) and isolating traffic on a dedicated network/VLAN. Using ephemeral port groups is not standard for iSCSI, and combining iSCSI with production traffic can create contention.
NEW QUESTION # 128
An administrator logged into NSX Manager to view host details. The administrator noticed that the
"Tunnel" status for the ESXi hosts, in the VI workload domain, is showing down.
What is a possible reason the ESXi host tunnels are showing down in NSX?
- A. The host TEP IP addresses are being dynamically assigned through DHCP instead of being statically assigned.
- B. The MTU setting for the host TEPs has been set to 1500.
- C. The overlay traffic is being blocked by the gateway firewall.
- D. The IGMP has been disabled on the network.
Answer: B
Explanation:
The "Tunnel" status in NSX indicates the status of the VXLAN tunnels used for communication between ESXi hosts. If the MTU setting for the host Tunnel Endpoint (TEP) is incorrectly set to 1500, this can cause issues with VXLAN encapsulation, as VXLAN packets typically require an MTU of at least 1600 bytes to function correctly. Setting the MTU too low can cause packet drops and result in the tunnel status being down.
NEW QUESTION # 129
What are three prerequisites for deploying an NSX Edge cluster in a VMware Cloud Foundation (VCF) solution? (Choose three.)
- A. Create DNS entries for the NSX Edge nodes.
- B. Set up vSAN storage policies for the Edge VMs.
- C. Install Aria Operations and enable Edge Cluster monitoring.
- D. Configure BGP as a dynamic routing protocol on the physical switches.
- E. Use separate VLAN IDs and subnets for the NSX host overlay and NSX Edge overlay networks.
- F. Verify that the NSX host overlay VLAN and NSX Edge overlay VLAN are routed to each other.
Answer: A,E,F
Explanation:
The NSX host overlay VLAN and NSX Edge overlay VLAN must be routed to each other so Edge nodes can establish overlay tunnels with transport nodes.
DNS A records for each NSX Edge node are required for name resolution during deployment and operation.
NSX requires distinct VLAN IDs and subnets for the host overlay network (transport nodes) and the Edge overlay network to segregate traffic and avoid IP space conflicts.

Explanation:
Live migration via vMotion (A), HA cluster settings (B), and DRS' automated host maintenance (C) collectively minimize service disruption. Disabling Resource Pools (D) is not typically a recommended strategy for maintenance.
NEW QUESTION # 131
When troubleshooting a virtual machine that has stopped responding in vSphere, which of the following actions or checks might help?
- A. Reviewing the vSphere Events and Tasks for errors
- B. Verifying if there is any Storage I/O Control contention
- C. Checking the VM's CPU ready time in performance charts
- D. Reinstalling the guest OS from scratch immediately
Answer: A,B,C
Explanation:
High CPU ready times can indicate CPU contention, event logs might show errors or misconfigurations, and SIOC might be throttling storage access. Reinstalling the OS (B) is an extreme step and not the typical first move.
NEW QUESTION # 132
A cloud administrator recently deployed a new VI workload domain. As part of the initial VI domain creation, the administrator created a new SSO domain. However, they reconsidered and now want the domain to use the same SSO domain as the management domain.
How can the VI domain be changed from a dedicated SSO domain to sharing the SSO domain with the management domain?
- A. From the Management Domain vCenter Server instance, use the rsautil command to add the VI workload domain to the management domain SSO ring.
- B. From the VI Workload Domain vCenter Server instance, use the rsautil command to join the management domain SSO ring.
- C. From the SDDC Manager console, use the rsautil command to add the VI workload domain to the management domain SSO ring.
- D. The vSphere SSO domain cannot be changed once it has been deployed and a new VI workload domain that is part of the Management SSO domain must be created, and workloads migrated.
Answer: D
Explanation:
Once the vSphere Single Sign-On (SSO) domain is set up for a workload domain, it cannot be changed.
If you need the VI workload domain to use the same SSO domain as the management domain, you must create a new VI workload domain that is part of the management domain's SSO ring, and then migrate the workloads to the new domain.
