Which planning consideration addresses whether the Instana backend remains usable when one of its supporting components fails?
Select an answer to reveal the explanation.
Short Explanation
You decide backend availability before install, because adding redundancy to a running backend is a migration, not a setting.
Full Explanation
The availability requirements of the backend services and datastores, decided before installation and reflected in how they are deployed, is the right planning consideration. How the backend services and their datastores are deployed determines what happens when one fails. That is an architectural decision taken during planning; changing it afterwards generally means rebuilding the deployment.
The naming convention chosen for monitored applications is incorrect because naming conventions aid readability but have no effect on resilience.
The number of Smart Alerts configured after the backend is running is incorrect because alerting configuration governs notification, not the availability of the platform doing the notifying.
The frequency with which agents are upgraded is incorrect because agent upgrade cadence affects the monitored estate rather than backend resilience.
For the exam, place availability alongside prerequisites and sizing as a decision made before installation.
