NCP-BC practice question 18 of 25

A company is recovering a 3-tier application (Database, Middleware, Web). The administrator executes the Recovery Plan. The Web tier VMs start up but applications immediately crash because they cannot connect to the Database tier. Which setting in the Recovery Plan should the administrator have configured to prevent this execution failure?

Answer options
A: Optional inter-stage delays Correct answer
B: AppType and AppTier category assignments
C: Protection Policy mapping
D: Automatic Volume Group attachments
Correct Answer:
A. Optional inter-stage delays
Explanation

Recovery Plans execute stages sequentially; if the Web-tier stage starts before the Database tier is on-line, dependent services fail. Configuring an “Optional Inter-Stage Delay” forces Prism to pause for a specified number of seconds between stages, guaranteeing the Database VMs have finished booting and accepted connections before the Web tier powers on, preventing the observed crash.

Why Incorrect

B. Categories aid grouping but do not enforce boot-time sequencing delays.
C. Policy mapping determines which data set is recovered, not VM start timing.
D. Volume Group attachment affects shared disks, unrelated to cross-tier boot order.
