Question 1

A Solution Architect is designing a Cloud Pak for Data v4.6 deployment for a financial institution that requires strict data isolation between departments. The requirement specifies that Department A and Department B must share the same OpenShift cluster but their workloads and data must be logically separated. Which architectural approach best satisfies this requirement?

Accepted Answer

Deploy multiple instances of Cloud Pak for Data, each in its own project (namespace), managed by a single set of operators in the ibm-common-services project.

Answer

Deploy a single instance of Cloud Pak for Data and use Platform User Groups to separate access.

Answer

Deploy a single instance of Cloud Pak for Data and use Tethered Projects to isolate the departmental workloads.

Answer

Deploy Cloud Pak for Data on separate physical OpenShift clusters for each department.

Question 2

An administrator is preparing to install Cloud Pak for Data v4.6 on a Red Hat OpenShift cluster. The deployment will include the Watson Knowledge Catalog service. Which storage class requirement must be verified during the planning phase to ensure service compatibility?

Accepted Answer

The storage class must support ReadWriteMany (RWX) access mode.

Answer

The storage class must support ReadWriteOnce (RWO) only.

Answer

The storage class must be based on local instance storage.

Answer

The storage class must rely solely on NFS version 3.

Question 3

You are planning the namespace structure for a new Cloud Pak for Data installation. You intend to use the Express installation method where operators and the platform instance coexist in the same project. Which project structure is correct for this topology?

Accepted Answer

A single project that contains both the Cloud Pak for Data operators and the Cloud Pak for Data instance.

Answer

One project for the operators (ibm-common-services) and one project for the Cloud Pak for Data instance (cpd-instance).

Answer

Three projects: one for operators, one for the control plane, and one for services.

Answer

One project for the platform and external projects for every individual service.

Question 4

A government agency requires a Cloud Pak for Data installation in a secure environment with no internet connectivity. Which component is MANDATORY to facilitate the transfer of container images from the IBM Entitled Registry to the air-gapped cluster?

Accepted Answer

An intermediary bastion host with connectivity to both the internet and the restricted network, or a portable storage device.

Answer

A transparent HTTP proxy connected to the IBM public cloud.

Answer

A VPN tunnel established directly between the OpenShift Master nodes and the IBM Entitled Registry.

Answer

The cpd-cli tool installed directly on the OpenShift worker nodes.

Question 5

While planning the deployment architecture for a production Cloud Pak for Data cluster, you need to ensure that the platform's control plane components are separated from the user workloads to ensure stability. Which Kubernetes feature should be utilized in the planning phase?

Accepted Answer

Node taints and tolerations

Answer

Namespace quotas

Answer

Pod Disruption Budgets

Answer

Service Mesh policies

Question 6

You are designing the storage architecture for a high-performance analytics workload on Cloud Pak for Data. The workload involves massive random I/O operations. Which storage class type is recommended for this specific scenario?

Accepted Answer

Block storage (e.g., OCS/ODF block, Portworx)

Answer

NFS (Network File System)

Answer

S3 Object Storage

Answer

HostPath storage
