The correct answer is C. Deploy the stretch duster sites to be within the distance of 300 miles apart. A customer requires a Cisco HyperFlex stretched cluster to ensure virtual server availability in case of a data center failure across multiple geographic locations.
Question
A customer must deploy a new Cisco HyperFlex stretched cluster solution to ensure virtual server availability in case the data center fails. The current network environment provides multiple geographic locations. Which action must be taken to meet these objectives?
Options
- AImplement the round trip time latency between the sites to be lower than 20 ms
- BPlace an independent witness component at a third site
- CDeploy the stretch duster sites to be within the distance of 300 miles apart
- DConfigure the cluster with the maximum data replication factor

Why each option
A customer requires a Cisco HyperFlex stretched cluster to ensure virtual server availability in case of a data center failure across multiple geographic locations.
While low latency is crucial, specifying a round-trip time (RTT) latency lower than 20 ms is a general performance requirement but does not directly address the action of deploying a stretched cluster, which has a primary distance constraint.
Placing an independent witness component at a third site is a crucial architectural component for HyperFlex stretched clusters to handle split-brain scenarios, but it is not the action taken to ensure virtual server availability between the primary sites.
Configuring the cluster with the maximum data replication factor (typically 3) increases data redundancy within the cluster but does not specifically address the requirements of a stretched cluster across geographically distinct data centers for site-level failure protection.
