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.)
---Page 19
Analyzing the Current State
Use monitoring tools to do an inventory of the existing infrastructure and report the resource usage.
For each system, capture peak and average utilization for the following items:
* CPU
* RAM
* IOPS
* Network utilization
---Page 96
Calculating the Total CPU and Memory Requirements
Multiply the adjusted total number of VMs by the average resource usage per server by using the CPU and RAM usage data from the capacity analysis report at peak utilization times.
When sizing hosts, use peak utilization levels rather than average utilization. In this way, all systems can run at their observed peak resource levels simultaneously.
---Page 192
Calculating Datastore Size
Average size of all VMDKs for a VM:
--- Number of VMs x Average size of VM's VMDK files = VM capacity
Sizing for average utilization always introduces the risk of workloads peaking at the same time. During peak utilization, the environment might be constrained for resources.
A customer has a database cluster with 40/60 read/write ratio and a high IOPs requirement with no contention on an all-flash vSAN cluster.
Which two storage settings should be configured for best performance? (Choose two.)
An architect is considering placement of virtual machines within an existing VMware software-defined data center (SDDC).
During the discovery phase, the following information is documented:
Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)
Profile 2 to Cluster 1
Fully Automated DRS allows Automated Initial VM Placement
TPS is enabled to support Memory Sharing requirement (can be used)
Profile 1 to Cluster 2
Partially Automated DRS still allows Automated Initial VM placement.
TPS is disabled to support Memory Sharing requirement (cannot be used)
An architect is designing a VMware solution for a customer based on the following information:
The solution must use investments in existing storage array that supports both block and file storage.
The solution must support the ability to migrate workloads between hosts within a cluster.
The solution must support resource management priorities.
The solution must support the ability to connect virtual machines directly to LUNs.
The solution should use existing IPv4 based network infrastructure.
There is no budget for additional physical hardware.
Which two design decisions could the architect make to meet these requirements? (Choose two.)
'The solution must support the ability to connect virtual machines directly to LUNs.' - this rules out non-block storage. 'The solution should use existing IPv4 based network infrastructure.' - this rules out FC.
An architect is tasked with planning the design of a new vSphere environment. When commissioned, this environment will be used to migrate an existing set of virtual machines.
An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided.
In order for each virtual machine to be migrated, which two data sources with peak and average utilization data are required for sizing? (Choose two.)
'which two data sources with peak and average utilization data are required for sizing'
Only CPU and IOPS provide peak and average values. You could get them using for example vRealize Operations Manager.
