Question 1

HyperFlex management, operations, and troubleshooting

Which three configurations are required for read caching in Cisco HyperFlex? (Choose three.)

A Write-back (default): Only write information and the most commonly used information are deposited in the cache.
B Level 4 cached (SSD): With semi-flash nodes, there is a large difference in read speeds between SSDs.
C No caching (SSD): With all-flash nodes, because there is little difference in read speeds between SSDs.
D Battery-Initiated Read-back (default): Only read data and most commonly used data are deposited in the Level 4 read-back cache.
E Write-through (install option for VDI): Only the most commonly used data is cached, optimizing VDI performance.
F Write-first (default for VDI): Infrequently used data is cached, freeing system resources for VDI performance.

What are two ways HyperFlex virtual servers differ from regular servers? (Choose two.)

E SP: UCS Service Profiles are used to delineate MAC address pools from upstream networks.

How is the maximum IO performance achieved?

A Use the HX 220 with all SAS drives.
B Use the HX 240 with all SAS drives.
C Use the HX 220 with all flash drives.
D Use the HX 240 with all flash drives.

The process of optimizing information is tightly tied to the writing process, as it is performed inline as the writing process is being performed.
With which two processes is data optimization performed? (Choose two.)

A On write, the local IOVisor sends the write to the primary CVM for that block.
B The secondary CVM compresses the data, reads it from its cache drive, and mirrors it.
C The primary CVM compresses the data, writes it to its cache drive, and mirrors it.
D ACK is sent to the CVM that the write is about to be initiated.
E On read/write, the distributed VAAI sends the write to the primary CVM for that block.

Which two features enable RAID card striping as well as mirroring and parity? (Choose two.)

A hot replacement of drives available, depending on configuration
B no load on the system resources, drives seem as one drive to the operating system
C distributed drives across disparate systems can be in RAID together
D on RAID card failure, the RAID onboard concurrent cache assists rebuild the cache
E integration with Cisco Intersight for a cloud-based storage management solution

Which three features are provided by managed deployments? (Choose three.)

A A decentralized yet complex management of an entire UCS domain.
B Individual configurations of each redundant fabric or global configuration.
C Ideal management of large deployments, scalability, and oversight of the UCS servers.
D High availability of the management system and connectivity when using two Cisco Fabric Interconnects.
E Consistent deployment by replicating working configurations from development labs to production deployment.
F Increased operating overhead and raised Operating Expenses (OpEx).

Which two components are automatically configured from the information provided to the HyperFlex installer? (Choose two.)

A vCenter integration
B server firmware policy
C application dependencies
D operating system deployment preparation
E ESXi configuration

Which action automatically builds the service profile in UCS Manager if a GPU card is installed in HyperFlex nodes before a cluster is created?

A Check the GPU workflow during the cluster creation process.
B Check Run UCS Manager Configuration during the cluster creation process.
C Check the extended memory option during the cluster creation process.
D Check the administrative workflow option during the cluster creation process.

Which two steps should be performed before installing HyperFlex? (Choose two.)

A Determine and download the virtual machine OS required.
B Determine and download recommended hypervisor.
C Determine and download recommended installer OVA version required.
D Complete the pre-installation checklist.
E Download service profile templates.

Which three additional management tools are included in HXDP to configure HyperFlex clusters? (Choose three.)

A REST API
B Data Center Network Manager
C HyperFlex Connect
D Storage CLI
E Cisco IMC

Which three functionalities are provided by VAAI? (Choose three.)

A Instead of the snapshot being performed in a hypervisor, it is offloaded to Cisco HXDP.
B VAAI performs caching, deduplication, and compression of data.
C Missing pieces of data are re-created from the remaining nodes in service.
D Cisco HXDP creates a file system native snapshot, which is registered in the vSphere.
E VAAI uses RAID to consolidate disks into a shared data platform.
F When a native snapshot is requested, the request is processed by the hypervisor.

When local writing or reading is performed, the IOVisor intercepts the read/write requests and forwards them to CVMs across the cluster. This action allows non-local CVMs to be aware of the input/output requests to perform the appropriate input/output action.

D enables asynchronous replication of data across individual HyperFlex nodes with sub-second re-convergence
E provides redundancy when local CVM fails, offloading data processing to another CVM in the cluster
