700-905 Cisco HyperFlex for Systems Engineers Questions and Answers

The primary CVM compresses the data, writes it to its cache drive and mirrors it

ACK is sent to the CVM that the write is about to be initiated

On write, the local lOVisor sends the write to the primary CVM for that block

On read/Write. the distributed VAAI sends the write to the primary CVM for that block

The secondary CVM compresses the data, reads it from its cache drive and mirrors it

Use HX 220s for compute nodes and HX 240s for converged nodes

Use B-Series servers to improve converged node scale.

Use the same CPU model but memory configuration can be different.

Use the same server configuration for the cluster.

Use the same server model for the cluster.

Distributed pooled data is migrated off nodes to master data store.

Affected node is marked as unhealthy and placed into standby mode

A call-home process is initiated and the failure is reported to TAC

The VMs on the failed node are moved to another node by vSphere high availability

The system is marked unhealthy but remains operational.

Virtualizing object storage environments by pushing meta data directly to the management server

The virtual interfaces created by a VIC do not accommodate hypervisor communication like VMkernel interfaces on vSphere.

Management through Cisco IMC or UCS Manager with dynamic configuration of virtual interface cards based on the server profile (MAC/WWN).

Traffic processing for internal and external communication supporting simultaneous HBA and NIC operation on the same physical hardware.

Multiple-interface-card virtualization without any additional driver requirements with integration of the virtualized cards into the Fabric Interconnect infrastructure.

A virtual environment, such as VMware vSphere, provides VM connectivity via a virtual switch to individual virtual machines bypassing local hardware requests.

creates hooks tor services related to third-party abstraction applications

does not perform caching, deduplication: and compression of data

an Ubuntu based VM running in the control space of each individual server, having linear access to the server ' s VMs and networking controls

needs network access to ESXi. other CVMs, and management network

is installed automatically by the HyperFlex installer, configured through the installer
