question 16

Multiple Choice

The customer has an indexer cluster supporting a wide variety of search needs, including scheduled search, data model acceleration, and summary indexing. Here is an excerpt from the cluster mater's server.conf : Which strategy represents the minimum and least disruptive change necessary to protect the searchability of the indexer cluster in case of indexer failure?

• A) Enable maintenance mode on the CM to prevent excessive fix-up and bring the failed indexer back online.
• B) Leave replication_factor=2 , increase search_factor=2 and enable summary_replication . Leave replication_factor=2 , increase search_factor=2 and enable summary_replication .
• C) Convert the cluster to multi-site and modify the server.conf to be site_replication_factor=2 , site _search_factor=2 . Convert the cluster to multi-site and modify the to be site_replication_factor=2 , site _search_factor=2
• D) Increase replication_factor=3 , search_factor=2 to protect the data, and allow there to always be a searchable copy. Increase replication_factor=3 , to protect the data, and allow there to always be a searchable copy.
