NCP Cluster Deployment and Configuration 2 — Questions and Answers
Question 1: Which Nutanix component is responsible for managing the distributed storage fabric across all nodes in a cluster?
- Acropolis
- Cassandra
- Stargate (Correct answer)
- Zookeeper
Correct answer: Stargate
Stargate is the Nutanix data I/O manager that handles all data operations and manages the distributed storage fabric.
Question 2: During Foundation-based cluster deployment, what is the correct order of operations?
- Image nodes → Create cluster → Configure network (Correct answer)
- Create cluster → Image nodes → Configure network
- Configure network → Create cluster → Image nodes
- Image nodes → Configure network → Create cluster
Correct answer: Image nodes → Create cluster → Configure network
Foundation first images all nodes with the specified AOS/hypervisor, then creates the cluster, followed by network configuration.
Question 3: What is the minimum number of nodes required to maintain data availability if one node fails in a Nutanix cluster configured with RF2?
- 1
- 2
- 3 (Correct answer)
- 4
Correct answer: 3
RF2 requires at least 3 nodes so that after one node failure, 2 surviving nodes can still satisfy the replication factor of 2.
Question 4: An administrator wants to enable Erasure Coding on a Nutanix cluster. What is the minimum number of nodes required?
- 2
- 3
- 4 (Correct answer)
- 6
Correct answer: 4
Erasure Coding (EC-X) requires a minimum of 4 nodes to distribute parity data effectively across the cluster.
Question 5: Which Nutanix CLI command is used to check the current cluster redundancy state after a node failure?
- ncli cluster get-domain-fault-tolerance-status
- ncli cluster info
- ncc health_checks run_all
- ncli cluster get-redundancy-state (Correct answer)
Correct answer: ncli cluster get-redundancy-state
The command 'ncli cluster get-redundancy-state' displays the current redundancy state and whether the cluster can tolerate additional failures.
Question 6: When configuring a Nutanix cluster for the first time via Prism Element, which default administrator credential is used?
- admin / Nutanix/4u (Correct answer)
- admin / admin
- nutanix / nutanix/4u
- root / nutanix/4u
Correct answer: admin / Nutanix/4u
The default Prism Element administrator credentials are username 'admin' and password 'Nutanix/4u', which must be changed on first login.
Question 7: A cluster is being expanded by adding new nodes. Which process automatically incorporates new nodes into the existing distributed storage fabric?
- Manual Curator scan
- Node discovery via Foundation
- Auto node addition via Prism workflow (Correct answer)
- Storage pool expansion via CLI
Correct answer: Auto node addition via Prism workflow
Prism's node expansion workflow automatically handles adding new nodes, including data rebalancing and integration into the storage fabric.
