質問 25
You have an Ezmejal Container Platform solution that manages an internally created Kubernetes cluster. The cluster uses AD for Its authentication settings, and users can successfully log into the platform with their domain credentials.
You have created a Tenant on the cluster which has the "AI/ML project" setting enabled on it. You have also created a Notebook cluster within that project. However, users receive an error when they try to log into the Notebook endpoint (Jupyter Hub) with their domain credentials.
What should you check?
- A. That the users have a manually created external account that assigns them to the Cluster Admin role in the cluster
- B. That the Notebook cluster has a "cluster" connection to the AD server hostname
- C. That the Notebook cluster has a "secret" connection with this value: "hpecp-ext-auth-secret"
- D. That the users have a manually created external account that assigns them to the Admin status in the AI/ML Project
正解: A
質問 26
A company IT department has strict requirements around data protection and wants you to explain how to use the Max Target and Mm Target options for an HPE Ezmeral Data Fabric volume.
What should you explain?
The Max Target sets the desired RAID level for data In the primary volume. The Mm Target sets the desired RAID level for data In associated mirror and snapshot volumes.
- A. The Max Target sets the desired number of replicas for data; the Min Target sets a replica number at which the fabric still tries to reach the Max Target, but less aggressively.
- B. The Max Target sets the desired number of replicas for "hot" (frequently used) data; the Min Target sets the desired number of replicas for "warm" (less frequently used) data.
- C. The Max Target and Min Target work together to set the erasure coding level for data in the volume. C.
The Max Target is the total number of blocks and the Min Target is the total minus redundant blocks.
正解: B
質問 27
You have used Ezmeral Container Platform to create a Kubernetes cluster, which has 3 conductor (master) nodes tor HA and 12 workers. Which correctly describes how the platform manages this cluster?
- A. The controller elects one conductor as the primary conductor and places the other conductors in standby mode.
- B. The controller can manage the cluster, but using HA for the conductors limits a few features such as Data Taps and the Web Terminal.
- C. The controller places the conductor nodes in standby mode and takes over as the active conductor for the Kubernetes cluster.
- D. The controller sends API requests through the gateway, which load balances them across the conductor nodes.
