54.Following a recent acquisition, the architect learns that both companies use vSphere on-premise and will need to combine the data centers into one. The acquired company's licenses will not be renewed for costsavings related to the acquisition. All consumed vSphere licenses must have active support to support lineof-business operations. The merged environment must maintain 25% spare capacity. The architect has asmall budget remaining unallocated for hardwarE、
The architect has calculated that the current vSphere environment can absorb the acquired company's virtual machines but the cluster will run at 90% memory utilization and at 50% CPU utilization.
Which design decision can the architect make to incorporate the new company's virtual machines into the combined vSphere environment?

A. 　 Migrate the acquired company's virtual machines into the vSphere environment as it will currently fit.

B. 　 Use the current budget to add memory to the cluster to increase each ESXi host's capacity and add the new virtual machines.

C. 　 Purchase extra hosts to add to the cluster in anticipation of adding the acquired company's virtual machines.

D. 　 Purchase new licenses for some of the acquired company's ESXi hosts and add them to the cluster to hold the acquired company's virtual machines.

67.A Cloud Service Provider wants to introduce backup as a service for a customer’s vSphere-based virtual machines.

The following information is noted:

They have a single four-port (2 × 10 GbE and 2 × 1 GbE) NIC per ESXi host.

All top-of-rack (ToR) switches are 10 GbE and fully populated.

The backup traffic must not impact existing services .

Which two recommendations should the architect make to help the customer incorporate the service?Choose two.

A. 　 Enable and tag traffic on the backup distributed port group

B. 　 Add a new two-port 10 GbE NIC per ESXi host

C. 　 Replace the existing NIC with a two-port 25 GbE NIC per ESXi host

D. 　 Match the Class of Service (CoS) and Differentiated Services Code Point (DSCP) values to the physical network

E. 　 Create a new virtual switch using the 1 GbE uplinks

G.

32.A customer requests a review of its current vSphere platform design.
The following information is noted:
There are three different workload profiles for the virtual machines:
- Tier-1 virtual machines operate resource-intensive applications and require dedicated allocations for CPU and RAM.
- Tier-2 virtual machines operate internet-facing applications and require access to externally facing networks.
- Tier-3 virtual machines operate platform management tools such as vCenter Server and have different lifecycle management requirements.
Tier-1, Tier-2 and Tier-3 virtual machines are all hosted on a single large vSphere cluster.
The Chief Information Security Officer ( ) has raised concerns that hosting externally facing applications alongside management tools does not meet internal compliance standards.
The Operations team has raised concerns about Tier-1 virtual machines negatively impacting the performance of vCenter Server.
The Operations lead has stated that management changes have consistently been rejected by application teams.

A. 　 Separate Tier-1, Tier-2 and Tier-3 virtual machines using dedicated distributed virtual switches (DVS)

B. 　 Separate Tier-2 virtual machines onto a dedicated cluster

C. 　 Separate Tier-1, Tier-2 and Tier-3 virtual machines onto dedicated clusters

D. 　 Separate Tier-1, Tier-2 and Tier-3 virtual machines using resource pools and shares

83.An architect is designing a new vSphere cluster. The requirement is to provide a total of 96 CPU cores and 1.5 TB RAM across all hosts.
The following information has been provided:
Two different physical hardware profiles are available for the ESXi hosts in the cluster.
- Profile 1: 16 CPU cores and 256 GB RAM
- Profile 2: 32 CPU cores and 512 GB RAM
Profile 2 is twice as expensive to purchase as Profile 1.
Which two aspects should the architect consider when selecting the hardware profile? Choose two.

A. 　 The manufacturer and model of the CPUs in the hosts

B. 　 The amount of capacity available for failover of virtual machines within the cluster

C. 　 The downtime allowed for virtual machines that will be running within the cluster

D. 　 The cost to procure and maintain the hardware

E. 　 The number of virtual machines that will be running within the cluster

20.Following a company merger, there are two data centers running vSphere environments. Both data centers are leveraging separate Layer 3 vMotion networks.
