Exam MCIA - Level 1 topic 1 question 9 discussion

C is the correct answer

It is C

it is C

C. Database polling continues Only HTTP requests sent to the remaining node continue to be accepted

if the primary is down then the command is automatically shifted to the serving node, so all request and polling is served by the remaining nodes and the ANS is C

When the primary node fails, the other one is automatically selected as new primary node. DB requests keeps polling because of they are resource-based connectors, so each one access the connection pool independently. In clusters, Listeners must be load balanced by an external solution. Once each HTTP Listener receives requests directly, so there’s no load balancer in this Architecture. It means that only the remaining node continues to receive HTTP requests.

C is the answer

Should be C. Because other node will continue db polling and http request. Only failed node will stop db polling and http requester.

Should be C. Cannot be D because increased latency means it will succeed in some time. However when the node comes up, it might have different IP which will mean requests sent to original ip might fail.

C. Database polling continues Only HTTP requests sent to the remaining node continue to be accepted

I agree C is correct

C is correct answer
