A customer is deploying a new cluster and wants to be able to patch and update two hosts in parallel. The cluster must be able to maintain N+1 resiliency across the remaining hosts while patching activities are performed. The current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.
What is the minimum number of hosts the customer will require in the cluster in order to meet the required resiliency level?
- A . Five
- B . Six
- C . Four
- D . Seven
The storage team at an organization is planning to migrate from an older Fibre Channel storage environment to a new environment using IP-based storage.
Which two switch features or characteristics are appropriate for IP storage networks? (Choose two.)
- A . Fabric extending devices
- B . Spanning Tree Protocol (STP)
- C . 2:1 or greater bandwidth oversubscription for 10 GbE switches
- D . Non-blocking switch
- E . Deep or ultra buffered switches
An architect is reviewing a physical storage design. The customer has specified that a new active-passive based storage array will be used to provide storage for the vSphere clusters.
Which configuration should for the architect recommended?
- A . VMW_SATP_LOCAL
- B . VMW_PSP_MRU
- C . VMW_SATP_DEFAULT_AA
- D . VMW_PSP_FIXED
During a requirements gathering workshop, the customer provides the following information:
✑ Each host has 2 × 10 GbE NIC
✑ EtherChannel is not currently configured
✑ No changes can be made to the physical network
✑ Network throughput must be prioritized for defined critical services
Which two recommendations should the architect make with regard to virtual networking? (Choose two.)
- A . Use Route Based on Physical NIC Load.
- B . Use Network I/O Control with Shares.
- C . Use Network I/O Control with Reservation.
- D . Use Link Aggregation Control Protocol (LACP).
- E . Use Network I/O Control with Limits.
Which two of the listed requirements would be classified as manageability non-functional requirements? (Choose two.)
- A . ESXi clusters must scale when compute resources are sustained above 70% for five business days
- B . vSphere Fault Tolerance must be supported to improve application uptime
- C . ESXi host updates must be installed within one week of release
- D . The vSphere environment must support administrator password rotation
- E . ESXi clusters must scale to 500 concurrent virtual machines
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.)
- A . The ESXi hosts will leverage Fibre Channel (FC)
- B . The ESXi hosts will leverage NFS 3
- C . The ESXi hosts will leverage Fibre Channel over Ethernet (FCoE)
- D . The ESXi hosts will leverage iSCSI
- E . The ESXi hosts will leverage NFS 4.1
A customer requires the use of data encryption to ensure data is not accessible when a drive is removed from the primary storage platform. However, there is also a requirement to use deduplication and compression against all workloads in order to conserve space.
Which solution meets the customer requirements?
- A . Data-in-transit encryption
- B . OS-level encryption
- C . Encrypted backups
- D . Array-based encryption
An architect is designing a new vSphere environment to meet the following requirements:
✑ The environment must support 5,000 virtual machines.
✑ The environment will be built initially using 350 hosts.
Which vCenter Server appliance deployment size should the architect specify for the design?
- A . Large
- B . Small
- C . Tiny
- D . Medium
A new real-time financial service application is being developed by the engineering team at a financial firm and will be released as a public Software-as-a-Service (SaaS) offering. The solutions architect has designed and deployed a new vSphere environment and the supporting network infrastructure for hosting all public services. ESXi hosts are configured to use Precision Time Protocol (PTP) and a local stratum-1 network time server.
Application provisioning and scaling will be managed by VMware vRealize Automation and can be run on Microsoft Windows or multiple distributions of Linux.
Which three recommendations should the architect include in the design to ensure that the service maintain timekeeping within an accuracy of one second? (Choose three.)
- A . Use Microsoft Windows Server as the guest operating system.
- B . Configure the chrony time-sync agent on each virtual machine guest operating system.
- C . Set the virtual hardware device to use Host System Time (NTP) for each virtual machine running the application.
- D . Add a precision clock virtual device to each virtual machine running the application.
- E . Use a Linux distribution as the guest operating system.
- F . Add a virtual watchdog timer (VWDT) device to each virtual machine running the application.
Which requirement would be classified as a functional requirement within the application design documentation?
- A . The application must be hosted with redundancy levels of N+1 or better.
- B . Penetration testing must be executed quarterly with a pass rate of 80% or higher.
- C . The application must be capable of handling 200 transactions per second.
- D . Administrators must monitor the network traffic of the desired systems.
