Suggested answer: D

Explanation:

A Multi-Site Orchestrator deployment requires two orchestrators to be deployed, one in each of the two main data center sites. The Multi-Site Orchestrator is a software component that enables the management and orchestration of multiple Cisco Application Centric Infrastructure (ACI) fabrics that are geographically distributed across different locations. The Multi-Site Orchestrator provides a single pane of glass for configuring, monitoring, and troubleshooting the ACI fabrics, as well as synchronizing policies and tenants across the sites. The Multi-Site Orchestrator also supports disaster recovery and high availability scenarios by allowing the replication of data and services between the sites. The Multi-Site Orchestrator deployment consists of two orchestrators that form a cluster and communicate with each other using a secure channel. Each orchestrator is connected to one or more ACI fabrics in the same site, and acts as a proxy for the other orchestrator to access the ACI fabrics in the remote site. The orchestrators use a leader-election algorithm to determine which one is the active orchestrator and which one is the standby orchestrator. The active orchestrator handles all the requests from the users and the applications, while the standby orchestrator monitors the health and status of the active orchestrator and takes over in case of a failure. The orchestrators also perform periodic data synchronization to ensure consistency and reliability.Reference:=
