NCP-DB practice question 18 of 35

Which action must an administrator take in Era Networks before using Era to provision a MSSQL AG cluster?

Full set: 251 questions

Answer options

A: A network in each data center must be configured for Era.

B: A private network must be configured in Era for the heartbeat traffic. Correct answer

C: A that has a static pool managed by Era must be configured.

D: A network that has a DHCP pool must be configured in Era.

Correct Answer:

B. A private network must be configured in Era for the heartbeat traffic.

Explanation

SQL Server Always On Availability Group clusters require an isolated Windows-cluster network for heartbeat and inter-node traffic. Era therefore demands that you first register a Private network in the Networks page before you can run the MSSQL AG provisioning wizard; without that network the workflow is blocked.

Why Incorrect

A. Separate networks per datacenter are optional; Era only insists on one private heartbeat network.
C. Static-IP pools are recommended but not a prerequisite for starting the AG workflow.
D. DHCP is not supported for Windows cluster IPs in Era AG deployments; a dedicated private network is required.
