Which server.conf attribute should be added to the master node's server.conf file when decommissioning a site in an indexer cluster?

To retire a site, you must tell the master where to send any bucket-level requests that still reference the old site. In server.conf [clusterconfig] you add the attribute sitemappings = :, mapping the decommissioned site to an active one.

B. availablesites lists all active sites but does not redirect a removed site.

C. sitesearchfactor defines search-time bucket copies, unrelated to decommissioning.

D. sitereplicationfactor defines data-time bucket copies, unrelated to decommissioning.
