– Access to configure the management virtual machines via vCenter Server must be controlled through the management Active Directory domain.
– Access to configure the Windows and Linux virtual machines must be controlled through the resource Active Directory domain.
– The management and resource Active Directory domains are part of separate Active Directory forests and do not have any trusts between them.

QUESTION 111
What is the main purpose of analyzing functional requirements?

QUESTION 112
An architect is designing a new vSphere architecture and notes the following information during the design workshops:
vSphere distributed switches (VDS) will be used for all vSphere clusters. Switch naming will be based on cluster name, resource type function and switch number.
Port group naming will be based on function, role and VLAN number range.
Each host has two physical network cards each with two NIC ports:
– Card A aligns to vmnic0 and vmnic1
– Card B aligns to vmnic2 and vmnic3
The architecture must provide resilient network connections.
Management Services will use VLAN ID 43.
Virtual machines access VLAN ID 100.
The vSphere infrastructure will use a hyper-converged storage architecture.
How should the architect document the VDS physical design based on the noted information?

QUESTION 113
An architect is planning the physical server configuration for a vSAN-based infrastructure.
Which operations mode should a RAID controller support to minimize potential server downtime during physical disk failures?

QUESTION 114
