3. An administrator has logged into their VxRail cluster and noticed that all nodes are in a
disconnected state. Upon logging into individual nodes, all workloads are running and no
services have been affected. The licensing applied to the cluster is still in Evaluation mode. The
administrator sees an unused vSphere License Key.
What steps should the administrator follow to properly license the cluster?
A. Select Administration > Licensing > Licenses, and apply a valid license key.
B. Select Administration > Licensing > Licenses > Assets > vSAN Clusters, and Assign License.
C. Select Administration > Licensing > Licenses > Add > Enter License Keys.
D. Select Administration > Licensing > Licenses > Synchronize Licenses.
Answer: A
4. Which VxRail networks support link aggregation1?
A. VxRail Management and vSAN
B. Private Management and VxRail Management
C. vSAN and vMotion
D. vMotion and VxRail Management
Answer: C
Explanation:
In VxRail networks, the vSAN and vMotion networks support link aggregation. Link aggregation
(also known as NIC teaming) allows multiple network interfaces to be combined into a single
logical interface, providing redundancy and increased throughput. This is particularly beneficial
for vSAN traffic, which requires high bandwidth and low latency, and vMotion traffic, which
benefits from increased network performance during virtual machine migrations.

communication within the cluster. Regular rekeying helps maintain data security by reducing the
risk of encryption key compromise.

42. What is the default load-balancing policy for VxRail Port Groups for a system deployed with
a predefined network profile1?
A. Route based on source MAC hash
10 / 12
B. Route based on IP hash.
C. Route based on physical NIC load
D. Route based on originating virtual port.
Answer: 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.
Reference: VMware vSphere Networking Guide
43. A VM is configured with hard disks totaling 100 GB allocated The VM is using a RAID 5
vSAN Storage Policy.
What is the total space that is consumed on the vSAN Datastore?
A. 200 GB
B. 100 GB
C. 133 GB
D. 166 GB
Answer: C
Explanation:
When a VM is configured with hard disks totaling 100 GB and uses a RAID 5 vSAN Storage
Policy, the total space consumed on the vSAN Datastore is approximately 133 GB. RAID 5 in
vSAN requires additional space for parity, which is typically about 1.33 times the original data
size. This means that for 100 GB of allocated space, the actual consumed space will be around
133 GB, accounting for the data and parity overhead.
