Question #: 9
Topic #: 1
An administrator has to implement high availability for various components of a Cloud Pak for Integration installation. Which two statements are true about the options available?
A.
DataPower gateway uses a Quorum mechanism where a global load balancer uses quorum algorithm to choose the active instance.
B.
Queue Manager (MQ) uses Replicated Data Queue Manager (RDQM).
C.
API management uses a quorum mechanism where components are deployed on a minimum of three failure domains.
D.
Platform Navigator uses an Active/Active deployment, where the primary handles all the traffic and in case of failure of the primary, the load balancer will then route the traffic to the secondary.
E.
AppConnect can use a mix of mechanisms - like failover for stateful workloads and active/active deployments for stateless workloads
High availability (HA) in IBM Cloud Pak for Integration (CP4I) v2021.2 is crucial to ensure continuous service availability and reliability. Different components use different HA mechanisms, and the correct options are B and C.
B. Queue Manager (MQ) uses Replicated Data Queue Manager (RDQM).
IBM MQ supports HA through Replicated Data Queue Manager (RDQM), which uses synchronous data replication across nodes.
This ensures failover to another node without data loss if the primary node goes down.
RDQM is an efficient HA solution for MQ in CP4I.
C. API management uses a quorum mechanism where components are deployed on a minimum of three failure domains.
API Connect in CP4I follows a quorum-based HA model, meaning that the deployment is designed to function across at least three failure domains (availability zones).
This ensures resilience and prevents split-brain scenarios in case of node failures.
Correct Answers Explanation:
A. DataPower gateway uses a Quorum mechanism where a global load balancer uses a quorum algorithm to choose the active instance. → Incorrect
DataPower typically operates in Active/Standby mode rather than a quorum-based model.
It can be deployed behind a global load balancer, but the quorum algorithm is not used to determine the active instance.
D. Platform Navigator uses an Active/Active deployment, where the primary handles all the traffic and in case of failure of the primary, the load balancer will then route the traffic to the secondary. → Incorrect
Platform Navigator does not follow a traditional Active/Active deployment.
It is typically deployed as a highly available microservice on OpenShift, distributing workloads across nodes.
E. AppConnect can use a mix of mechanisms - like failover for stateful workloads and active/active deployments for stateless workloads. → Incorrect
While AppConnect can be deployed in Active/Active mode, it does not necessarily mix failover and active/active mechanisms explicitly for HA purposes.
Incorrect Answers Explanation:
IBM MQ High Availability and RDQM
IBM API Connect High Availability
IBM DataPower Gateway HA Deployment
