From the “Promoting the replica administrative node” documentation:
“Open the/conf/run.propertiesfile in a text editor. Locate thepa.operational.modeline and change the value fromCLUSTERED_CONSOLE_REPLICAtoCLUSTERED_CONSOLE. These properties are case-sensitive. Do not restart the replica node during the promotion process.”Ping Identity Documentation
Also from the documentation under “Next steps” / manual promotion / “Using the admin API …”When promoting the replica, there is also mention of setting the new host-port in the primary admin configuration so that engine nodes and configuration references now point to the promoted replica. One of the API properties iseditRunPropertyFile(to flip the mode), another iseditPrimaryHostPort, which causes the primary-admin host setting to be updated.Ping Identity Documentation
Using those facts:
Why C is correct:
Option C says:Changepa.operational.modetoCLUSTERED_CONSOLEon the replica admin node.This directly matches the documented manual promotion step: switchpa.operational.modefromCLUSTERED_CONSOLE_REPLICA→CLUSTERED_CONSOLE.Ping Identity Documentation+1
This is essential for promoting the replica to primary console.
Why E is correct:
Option E:Modifybootstrap.propertiesand set theengine.admin.configuration.hostvalue to point at the replica admin node.While the documentation doesn’t always name the exact propertyengine.admin.configuration.host, the “promote via admin API” includes updating the “primary host:port” in the configuration so that engine nodes’ configuration queries (or whatever is used by engines) point to the new primary. This maps to ensuring that engine nodes know that the promoted replica is now the administrative node. This requiring modifying the bootstrap or configuration that engine nodes use to find the administrative host is essential.Ping Identity Documentation
Why the other options are incorrect:
A.Changepa.operational.modetoCLUSTERED_CONSOLE_REPLICAon one of the engine nodes.No. Engine nodes should havepa.operational.mode = CLUSTERED_ENGINE, not console modes.CLUSTERED_CONSOLE_REPLICAis an admin/replica console mode, not applicable for engines.docs.ping.directory+2Ping Identity Documentation+2
B.Restart all nodes in the cluster.The documentation explicitly saysdo not restartthe replica node during the promotion process because restart can cause file corruption or failure to properly promote. Only certain restarts are neededafterconfiguration updates. So restarting all nodes is not a correct required action.Ping Identity Documentation
D.Restart the replica admin node.As above, for manual promotion, a restart of the replica admin node isnotrequired (and is even discouraged during the promotion process). The change inrun.propertiesis detected without restarting.Ping Identity Documentation
