NEW QUESTION # 35
An architect is designing storage for a new vSphere environment to meet the following requirements:
Asynchronous replication is required between two sites.
The impact on the storage layer should not impact the performance of the compute layer.
Each application tier will require different replication attributes.
Virtual machine live migration across compute and storage must be supported.
Virtual machine aware back up will be leveraged.
Operational management overhead should be minimized.
Operational automation should be supported.
Which storage design recommendations would meet the requirements?

A. Two new storage arrays will be deployed, one at either site.
vSphere Volumes (vVOLs) will be used to provide policy-based management for each application tier. Data replication will be offloaded to the new arrays.
B. Two new Fibre Channel storage arrays will be deployed, one at either site.
Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays.
C. Two new ISCSI storage arrays will be deployed, one at either site.
Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays.
D. Two new vSphere clusters enabled with vSAN will be deployed, one at either site. vSAN will be used to provide policy-based management for each application tier.
vSphere Replication will be used to replicate the virtual machine data in an asynchronous configuration.

Answer: A

Explanation:
vVOLs accomplish each one of the requirements, but specially this one: "Virtual machine aware back up will be leveraged" Here references:

NEW QUESTION # 36
An architect is designing a new greenfield environment that will install ESXi on local disks. There is a requirement to streamline initial and future installations of ESXi hosts.
Which configuration option should the architect recommend for installing ESXi hosts to meet these requirements?

A. Auto Deploy with stateful install mode
B. Installation with kick start script
C. Auto Deploy with stateless caching mode
D. Manual installation using boot from SAN

Answer: A

Explanation:
Stateful Install: When a host is booted for the first time, the host profile configuration states Auto Deploy is to install ESXi on local host storage. All consecutive host boots, only the local storage is used until the image profile configuration is changed. Stateless: Auto Deploy is used to install ESXi in memory on the target host. The state information of the ESXi host is managed by Auto Deploy. No local storage is required.

NEW QUESTION # 39
An architect is tasked with reviewing the design of a VMware software-defined data center (SDDC) for a software development company. The platform is used to developing applications and services. It is important that the customer be able to accurately benchmark performance of developed applications.
The platform has recently commissioned new hosts to update the development cluster.
The development cluster host configuration is:
* 4 ESXi hosts with 2 sockets × 16 cores
* 512 GB RAM divided evenly between sockets
* There is no resource contention
The benchmarking cluster host configuration is:
* 8 ESXi hosts with 2 sockets × 8 cores
* 256 GB RAM divided evenly between sockets
* There is no resource contention
The customer is developing an application that includes a database virtual machine. The application developer states that the database virtual machine performs as required only when allocated 8 vCPUs 256 GB RAM. The database virtual machine performance meets the required levels when run from the development cluster.
Performance benchmarking for the database virtual machine yields highly variable results when run from the benchmarking cluster. The application cannot be released without reliable performance benchmarking data.
What is a possible reason for the difference in performance test results between the development and benchmarking clusters?

A. The development cluster has more available RAM per host
B. The database tier breaches a single NUMA node boundary for the development cluster
C. The database tier breaches a single NUMA node boundary for the benchmarking cluster
D. The development cluster can support a lower %Ready time per vCPU

NEW QUESTION # 51
A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.
Per the defined logical network configuration, there are two network adapters each used for:
Management traffic
vMotion traffic
iSCSI traffic
Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?

A. Combine vMotion and Management traffic to make use of four adapters.
B. Use Network I/O Control to define a reservation for vMotion traffic.
C. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
D. Configure a dedicated TCP/IP stack for vMotion traffic.

Answer: C

Explanation:
https://kb.vmware.com/s/article/2007467
https://communities.vmware.com/t5/VMware-vSphere-Discussions/vmotion-load-balanced-across-multiple-uplinks-on-distributed/td-p/491336
https://www.virtuallyboring.com/multi-nic-vmotion/
We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernel interfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it for vMotion, you create a new stream. With more streams, there is greater bandwidth utilization.
https://kb.vmware.com/s/article/2007467
https://communities.vmware.com/t5/VMware-vSphere-Discussions/vmotion-load-balanced-across-multiple-uplinks-on-distributed/td-p/491336
https://www.virtuallyboring.com/multi-nic-vmotion/
Even though 2 x network adapters are dedicated to vMotion, only 1 of the uplinks will be used during a vMotion activity if only one vMotion vmkernel is configured. Adding an additional vmkernel will allow both to be used.
Per the VMware KB above "After making these configuration changes, when you initiate a vMotion, multiple NIC ports are used. Even when performing a vMotion on just one virtual machine, both links are used." Also the question states "Per the defined logical network configuration, there are two network adapters each" which suggests that changing this to combine vMotion/Mgmt traffic may not be possible based on the customers requirements (as the logical network architecture is already defined by them)

NEW QUESTION # 57
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 to 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 operations monitoring tools have sufficient capacity to monitor the new VDI services
B. The existing management cluster has enough available capacity to host any VDI service management component
C. The existing virtual infrastructure has sufficient capacity to host the new VDI workloads
D. The VDI service has a higher service-level agreement (SLA) than the operations management SLA
E. The management cluster has N+1 redundancy

Answer: A,E
