C1000-168 Sample Questions

  1. Question 1

    Intermediate

    Planning · Describe the multi-tenancy support with Cloud Pak for Data

    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?

    Answer and explanation

    Correct answer: D

    Cloud Pak for Data supports multi-tenancy by allowing multiple instances of the platform to be installed on the same OpenShift cluster. Each instance resides in its own project (namespace), providing logical isolation of data and workloads while sharing the underlying cluster resources and common operators.

  2. Question 2

    Intermediate

    Planning · Describe the tasks needed for pre-reqs for installation

    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?

    Answer and explanation

    Correct answer: C

    Many Cloud Pak for Data services, including Watson Knowledge Catalog, require shared storage that supports the ReadWriteMany (RWX) access mode to allow multiple pods to read and write to the same volume simultaneously.

  3. Question 3

    Beginner

    Planning · Determine how many projects are needed to install Cloud Pak for Data

    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?

    Answer and explanation

    Correct answer: B

    In an Express installation (often used for non-production or simple setups), the operators and the Cloud Pak for Data instance can be installed in the same project/namespace. This simplifies management but reduces isolation.

  4. Question 4

    Intermediate

    Planning · Explain the difference between online and air-gapped installation

    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?

    Answer and explanation

    Correct answer: D

    In air-gapped environments, a bastion host (or a portable compute device) is required to pull images from the source registry (IBM Entitled Registry) and then mirror/push them to the private registry inside the restricted network.

  5. Question 5

    Advanced

    Planning · Explain the use of node/pod affinity

    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?

    Answer and explanation

    Correct answer: C

    Applying taints to specific nodes ensures that only pods with matching tolerations can be scheduled on them. This allows administrators to dedicate specific worker nodes for the Cloud Pak for Data control plane or specific services, isolating them from general workloads.

  6. Question 6

    Intermediate

    Planning · Describe the deployment architecture

    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?

    Answer and explanation

    Correct answer: D

    Block storage is generally recommended for databases and high-performance analytics workloads requiring high random I/O throughput, as opposed to file-based storage like NFS which may introduce latency.
