   A Splunk search head cluster has 3 members. The captain's host loses power and does not recover. The remaining 2 members elect a new captain. However, one of the 2 members has a corrupted configuration that prevents it from joining the cluster. What is the most likely outcome?

   • AThe healthy member becomes captain because it has the highest term and can operate alone.
   • BThe healthy member continues to serve searches but cannot make configuration changes.
   • CThe remaining healthy member cannot form a quorum alone, so the cluster cannot elect a captain and becomes unavailable.
   • DThe cluster automatically reduces its quorum to 1 because 2 members are down.

   A Splunk search head cluster has 3 members. The captain sends heartbeats every 1 second. A follower's election timeout is 5 seconds. The captain's host experiences a 7-second hang. What is the most likely sequence of events?

   • AThe follower waits for the captain to recover because the hang is only 7 seconds and the election timeout is 5 seconds.
   • BThe follower becomes a candidate but cannot win because the captain recovers before the election completes.
   • CThe follower times out after 5 seconds, becomes a candidate, and requests votes. The other follower grants its vote, and the candidate becomes the new captain.

   A search head cluster has 5 members. During a network partition, 2 members are isolated from the other 3. The 3-member side elects a new captain. Later, the partition heals and all 5 members can communicate again. What happens to the 2 isolated members?

   • AThey shut down immediately because they cannot maintain quorum and the cluster requires all members to be present.
   • BThey continue operating as a separate cluster with their own captain because they had a quorum of 2.
   • CThey become followers of the new captain, accept its heartbeat, and rejoin the cluster as followers.
   • DThey force a new election across all 5 members because their terms are higher than the new captain's term.

   A Splunk search head cluster has 7 members. The captain fails permanently. After the election timeout, 3 members become candidates simultaneously, each with a different term. What is the minimum number of votes a single candidate must receive to become the new captain?

   • A3 votes, because the candidate with the highest term only needs votes from the other two candidates.
   • B4 votes, because a majority of the 7-member cluster is required.
   • C5 votes, because with 3 candidates, the winner must have more votes than the other two combined.
   • D2 votes, because the candidate with the highest term wins by default and only needs one additional vote to confirm.
