Which vSphere integrated component must be installed on the VxRail cluster that is used to run
containers?
A
Explanation:
The vSphere integrated component that must be installed on the VxRail cluster to run containers is
VMware Tanzu. VMware Tanzu enables Kubernetes container orchestration within a VMware
environment, integrating with vSphere to provide a platform for managing containers alongside
virtual machines. This allows administrators to deploy and manage containerized applications using
the same tools and processes they use for VMs.

An administrator wants to get information about a specific host and runs this code:
GET/v1/hosts/{sn}
An API code 404 is returned
What is the reason for the error code?
B
Explanation:
The error code 404 indicates that the requested resource could not be found on the server. In the
context of the API call GET/v1/hosts/{sn}, the 404 error is returned because the serial number (sn)
provided was not valid or does not exist in the database. This means the server could not find any
host that matches the provided serial number.

Which command is used to unlock the mystic account on the VxRail Manager VM?
D
Explanation:
To unlock the mystic account on the VxRail Manager VM, the command used is pam_tally2 --
user=mystic --reset. This command resets the failed login attempts counter for the specified user,
unlocking the account if it was locked due to too many failed login attempts.
Steps to unlock:
Access the VxRail Manager VM through SSH.
Execute the command pam_tally2 --user=mystic --reset.
Verify that the account is unlocked and can log in successfully.

What is the default load-balancing policy for VxRail Port Groups for a system deployed with a
predefined network profile1?
D
Explanation:
The default load-balancing policy for VxRail Port Groups in a system deployed with a predefined
network profile is "Route based on originating virtual port." This policy distributes network traffic
based on the virtual port ID from which the traffic originates, ensuring that traffic from a particular
virtual machine (VM) is consistently routed through the same physical network adapter.

VxRail nodes have been purchased to add additional capacity The new nodes are based on AMD
Chipset, the current cluster is based on Intel Chipset
What should be the next step?
B
Explanation:
When adding VxRail nodes based on a different chipset (e.g., AMD vs. Intel) to an existing cluster, it is
necessary to enable VMware Enhanced vMotion Compatibility (EVC) mode. EVC ensures CPU
compatibility for vMotion by masking certain CPU features, making it possible to add nodes with
different processors to the same cluster without causing compatibility issues.
Steps:
Enable VMware EVC mode on the existing cluster.
Ensure all cluster nodes meet the EVC requirements.
Add the new AMD-based nodes to the existing cluster.

What is the vSAN automatic rebalancing threshold recommended by VMware?
D
Explanation:
The recommended vSAN automatic rebalancing threshold by VMware is 20%. This threshold ensures
that vSAN automatically initiates rebalancing operations when the storage utilization across the disks
in the vSAN datastore becomes uneven beyond this threshold, maintaining optimal performance and
storage efficiency.
Reference: VMware vSAN Rebalancing Guide
In the vSphere Client, where is VxRail Health Monitoring enabled?
B
Explanation:
In the vSphere Client, VxRail Health Monitoring is enabled under Cluster > Configure > VxRail. This
section provides an interface for configuring and monitoring VxRail-specific health and performance
metrics, ensuring that administrators can effectively manage and monitor their VxRail clusters.
Steps:
Open the vSphere Client.
Navigate to the specific cluster.
Go to the Configure tab.
Select VxRail from the list.

What are two failure states of vSAN components? (Select 2)
B, C
Explanation:
The two failure states of vSAN components are "Degraded" and "Absent."
Degraded: A vSAN component is considered degraded when it is still accessible but has experienced
a loss of redundancy or other performance issues. This state indicates that the data is still available
but may be at risk if further failures occur.
Absent: A vSAN component is in an absent state when it is temporarily unavailable, often due to
transient issues like network disconnections or host reboots. The system expects the component to
return shortly.
Reference: VMware vSAN Component State Guide
What is the maximum number of days vSAN capacity history is available'?
D
Explanation:
The maximum number of days vSAN capacity history is available is 120 days. vSAN maintains a rolling
history of capacity usage, providing detailed insights into storage trends and helping administrators
manage and forecast storage requirements effectively.

What is a consideration when scaling a VxRail cluster?
C
Explanation:
When scaling a VxRail cluster, it is important to consider that mixing VxRail nodes with different base
network speeds is not permitted. This restriction ensures network consistency and performance
across the cluster, avoiding potential issues with data flow and latency caused by differing network
speeds.

Which level of data protection can be configured across sites in a VxRail Stretched Cluster1?
C
Explanation:
In a VxRail Stretched Cluster, RAID 1 can be configured across sites to provide data protection. RAID 1
(mirroring) ensures that data is replicated across two sites, providing high availability and data
redundancy in case one site fails. This configuration helps maintain continuous operations and data
integrity in a multi-site deployment.

A VxRail Cluster has been deployed with four VxRail E560 nodes each using tour integrated NIC ports
and the default network profile.
Which vmnics carry the VxRail management traffic, and in what teaming and failover configuration?
C
Explanation:
For a VxRail cluster deployed with four VxRail E560 nodes using four integrated NIC ports and the
default network profile, the VxRail management traffic is carried by vmnic0 and vmnic1 in an
active/standby configuration with no link aggregation. This setup ensures redundancy and failover
capabilities for the management network, enhancing the cluster's reliability and resilience.

Which resource enables an administrator to create a procedure for upgrading a VxRail cluster?
A
Explanation:
The resource that enables an administrator to create a procedure for upgrading a VxRail cluster is
SolVe Online. SolVe Online is a web-based tool provided by Dell Technologies that offers
comprehensive procedures and best practices for various Dell EMC solutions, including VxRail. It
provides detailed, step-by-step guidance for a variety of tasks, including upgrades, ensuring that
administrators follow the correct procedures to maintain system integrity and minimize downtime.

Which service on the ESXi host allows automatic discovery when adding a node into an existing
VxRail Cluster*?
A
Explanation:
The service on the ESXi host that allows automatic discovery when adding a node into an existing
VxRail Cluster is "loudmouth." Loudmouth is a lightweight messaging daemon that enables the
nodes in a VxRail cluster to discover each other automatically. This service facilitates the seamless
addition of new nodes into an existing VxRail cluster by enabling them to communicate and integrate
without manual configuration.

What authorization method is used tor VxRail API calls?
B
Explanation:
The authorization method used for VxRail API calls is HTTP Basic. This method requires the client to
send the user’s credentials (username and password) encoded in Base64 within an HTTP header.
HTTP Basic authentication is straightforward and is supported by most HTTP clients, making it a
suitable choice for securing API calls in VxRail environments.
