A. Installation with kick start script
B. Auto Deploy with stateless caching mode
C. Manual installation using boot from SAN
D. Auto Deploy with stateful install mode
An architect is designing a solution based on the following information: ✑ Each ESXi host has a single physical NIC with two 10 Gbps ports. ✑ There is a performance-based service-level agreement (SLA) that guarantees 15 Gbps bandwidth for production virtual machines at all times. ✑ There is no budget to purchase additional hardware. ✑ The hardware replacement SLA is based on a delivery agreement of two business days. Which recommendation for the configuration of vSphere High Availability (HA) should the architect include in the design?
A. Configure vSphere HA Configure % based admission control Configure two isolation addresses Consider an OEM with NIC failure conditions in their Proactive HA plugin
B. Configure vSphere HA Set das.IgnoreRedundantNetWarning to true Consider an OEM with NIC failure conditions in their Proactive HA plugin
C. Configure vSphere HA Configure two existing data stores for heartbeat Consider an OEM with NIC failure conditions in their Proactive HA plugin
D. Configure Proactive HA Automation Level: Automated Remediation: Maintenance mode for all failures Consider an OEM with NIC failure conditions in their Proactive HA plugin
Which of the listed requirements would be classified as a recoverability non-functional requirement?
A. The platform must be integrated with existing change control policies.
B. The platform must be able to support a maximum tolerable downtime (MTD) of 30 minutes.
C. Maintenance windows must be scheduled to take place monthly during an established overnight period.
D. The platform must be available 24 hours a day, 7 days a week with the exception of scheduled downtime.
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.)
A. %Ready
B. Disk Write latency
C. CPU
D. Ballooned memory
E. IOPS
An architect is designing a vSphere environment for a customer based on the following information: ✑ The vSphere cluster will have three hosts only due to budget considerations. ✑ A database cluster (node majority) consisting of three virtual machines will be running on the vSphere cluster. Which two recommendations can the architect make so that the customer achieves the highest level of application availability while taking into consideration operational resiliency? (Choose two.)
A. Create VM-VM anti-affinity rules
B. Set das.respectvmvmantiaffinityrules to false
C. Create VM-Host anti-affinity rules
D. Disable vSphere HA during maintenance
E. Set das.ignoreinsufficienthbdatastore to true
What is a benefit of using a scale-out method for handling vSphere cluster growth?
A. An increase in the recovery time objective (RTO) for the cluster
B. Faster to reach the limit of virtual machines per host
C. An overall reduction in the license costs for the cluster
D. Less potential impact to virtual machines during a single host failure
An architect is designing a new vSphere environment to meet the following requirements: ✑ The environment must support 800 virtual machines. ✑ The environment will be built initially using 200 hosts. Which vCenter Server appliance deployment size should the architect specify for the design?
A. Large
B. Small
C. X-Large
D. Medium
An architect is designing the expansion of an existing vSphere 7 environment. The customer is requesting a design for a new cluster to support the anticipated future business growth. The requirements specified for the existing environment design must be considered when designing the new cluster. The existing design has the following requirements: ✑ REQ01 The environment has an availability target of 99.5% for all infrastructure. ✑ REQ02 The recovery time objective (RTO) for Tier 1 virtual machines is one hour. ✑ REQ03 Windows and Linux virtual machines must reside on separate clusters. ✑ REQ04 Access to the management cluster within the environment must be controlled. Which of the listed requirements would be classified as a functional requirement?
A. The environment has an availability target of 99.5% for all infrastructure
B. The recovery time objective (RTO) for Tier 1 virtual machines is one hour
C. Access to the management cluster within the environment must be controlled
D. Windows and Linux virtual machines must reside on separate clusters
An architect makes the design decision to install ESXi on embedded and resilient 8 GB SD cards. What is the impact of this design decision?
A. Host profiles must be used for this kind of installation
B. Scratch partition would need to be created on the external storage
C. The size of the SD cards is too small and the installation will fail
D. The vSphere Auto Deploy feature must be enabled on vCenter Server
