QUESTION 6
An architect is designing a VMware software-defined data center (SDDC) solution based on the following customer
requirements: The solution must initially support 1,000 virtual machines The solution must scale to support the
concurrent running of up to 5,000 virtual machines The production environment should be delivered across two data
centers The solution should have a maximum tolerable downtime (MTD) of four hours The solution should have a
monthly service availability target of 99.8%
Which two assumptions could the architect make based on the information from the customer to help size the solution? (Choose two.)
A. The number of vSphere hosts in a cluster
B. The average resource utilization of a virtual machine
C. The size (CPU/RAM/storage) of the average virtual machine
D. The guest operating system for each virtual machine
E. The size (CPU/RAM/storage) of the vSphere hosts
Correct Answer: AE
QUESTION 7
A VMware Service Provider is tasked with delivering a solution for continuous availability for a subset of Tier 1 virtual
machines (VMs) and vApps running in their vSAN environment. The VMs make up a mission-critical application and
there can be no data loss in the event of an outage at their primary data center.
In the event of a regional outage, they have established a 10-minute recovery point objective (RPO). Failover/ failback to the third side must be automated.
They have the following in place:
Two local data centers (primary and secondary) connected with 100 Gb dedicated fiber
-2ms round-trip time (RTT) latency between the sites A third data center located on another power grid
-70ms latency between the primary and secondary data centers Matching storage arrays at all locations
Which two solutions could be used to meet the requirements? (Choose two.)
A. Site Recovery Manager
B. Snapshots
C. vSAN Metro Cluster
D. vSphere Data Protection

QUESTION 10
An architect is tasked with expanding an existing VMware software-defined data center (SDDC) solution so that it can
be used to deliver a virtual desktop infrastructure (VDI) service off-shore development activities.
The production environment is currently delivered across two geographically dispersed data centers. The two data
centers are currently connected to each other through multiple diversely routed, high bandwidth, and low latency links.
The current operations management components are deployed to a dedicated management cluster that is configured
with N+1 redundancy.
The current VMware software-defined data center (SDDC) has a monthly availability target of
99.5%, which includes all management components.
The customer requires that the new solution scale support the concurrent running of 500 persistent virtual desktops.
The virtual desktops must not share the same virtual infrastructure as existing virtual machines, but can be managed
using the same VMware operations management components.
Any new VDI service management components must be installed into the management cluster. There is no requirement to back up the virtual desktops because all relevant user data is stored centrally. The VDI service is providing business-critical services and must have an availability target of 99.9%. Given the information from the customer, which two assumptions would the architect include in the design? (Choose two.)
A. The existing virtual infrastructure has sufficient capacity to host the new VDI workloads
B. The existing operations monitoring tools have sufficient capacity to monitor the new VDI services
C. The existing management cluster has enough available capacity to host any VDI service management component
D. The management cluster has N+1 redundancy
E. The VDI service has a higher service-level agreement (SLA) than the operations management SLA
Correct Answer: AB

B. Stateful vSphere Auto Deploy
C. Scripted installation
D. Interactive installation
Correct Answer: C
QUESTION 12
During a requirements gathering workshop to design a physical to virtual migration, the customer provides
the following information:
There is no physical firewall in the data center with no anticipated plans for a future network refresh.
Leveraging the virtual infrastructure to mitigate the lack of network security must be addressed in the
design.

virtual networking?
A. Split the virtual machines into several VLANs Use tag actions
B. Create port groups with different names and the same VLAN IDs Enable traffic shaping for ingress and egress traffic
C. Enable traffic filtering and marking Use allow or drop actions
