Question

An engineer must deploy a Cisco HyperFlex system at two data centers. For redundancy reasons, the setup must achieve data protection in case of an entire site failure. The data must be available on both sites at all times to keep the recovery time objective to a minimum. Which Cisco HyperFlex deployment model meets these requirements?

Options

  • AROBO cluster
  • Bstretched cluster
  • Cedge with four nodes or more
  • Dstandard with eight nodes

Why each option

To deploy a Cisco HyperFlex system across two data centers for site-wide redundancy, continuous data availability, and minimal Recovery Time Objective (RTO), a stretched cluster deployment model is required.

AROBO cluster

A ROBO (Remote Office/Branch Office) cluster is designed for smaller, usually single-site remote deployments and does not typically offer the cross-data center redundancy or active-active data availability required for minimal RTO in case of an entire site failure.

Bstretched clusterCorrect

A Cisco HyperFlex stretched cluster deployment extends a single HyperFlex cluster across two geographically separated data centers, operating in an active-active configuration. This model provides robust data protection against an entire site failure by ensuring data is simultaneously available on both sites, which is critical for achieving a near-zero Recovery Time Objective (RTO) through transparent VM failover.

Cedge with four nodes or more

'Edge with four nodes or more' describes a deployment size for edge computing scenarios, but it does not inherently provide the cross-data center redundancy, active-active data availability, or RTO guarantees needed for an entire site failure.

Dstandard with eight nodes

'Standard with eight nodes' describes a typical deployment size for a single-site HyperFlex cluster. While it provides high availability within that site, it does not offer data protection or availability across two distinct data centers in the event of an entire site failure.
