HP Virtualization & Container Technology 2 — Questions and Answers
Question 1: Which HP ProLiant feature allows multiple virtual machines to share a single physical NIC while maintaining network isolation?
- HP Virtual Connect
- SR-IOV (Single Root I/O Virtualization) (Correct answer)
- VLAN tagging via HPE Smart Array
- HPE iLO NIC teaming
Correct answer: SR-IOV (Single Root I/O Virtualization)
SR-IOV allows a single physical NIC to present multiple virtual functions to VMs, enabling direct hardware access with isolation.
Question 2: In HPE Synergy, what component manages the logical server profiles used for VM host provisioning?
- HPE OneView Composer (Correct answer)
- HPE iLO Amplifier Pack
- HPE Service Pack for ProLiant
- HPE Insight Control
Correct answer: HPE OneView Composer
HPE OneView Composer in Synergy manages server profiles, templates, and logical infrastructure for composable compute.
Question 3: A Docker container exits immediately after launch despite a correct image. What is the most likely cause?
- The container image is too large
- The entrypoint process completes and no foreground process remains (Correct answer)
- Docker daemon is not running in privileged mode
- The host kernel version is incompatible
Correct answer: The entrypoint process completes and no foreground process remains
Containers run as long as their main process runs; if the entrypoint exits, the container stops immediately.
Question 4: Which HPE tool provides unified firmware and driver management across hypervisor hosts in a virtualized environment?
- HPE SUM (Smart Update Manager) (Correct answer)
- HPE Systems Insight Manager
- HPE iLO Federation
- HPE Virtual Connect Manager
Correct answer: HPE SUM (Smart Update Manager)
HPE Smart Update Manager (SUM) automates firmware and driver updates across physical and hypervisor hosts from a single interface.
Question 5: What is the purpose of a Kubernetes PersistentVolumeClaim (PVC)?
- To define resource limits for a Pod's CPU usage
- To allow a Pod to request durable storage independent of its lifecycle (Correct answer)
- To expose a service externally via a load balancer
- To schedule Pods onto specific nodes based on labels
Correct answer: To allow a Pod to request durable storage independent of its lifecycle
A PVC is a user's request for storage that binds to a PersistentVolume, surviving pod restarts and rescheduling.
Question 6: When configuring VM memory overcommitment on an HPE ProLiant host running VMware, which feature reclaims unused guest memory without pausing the VM?
- Memory ballooning (Correct answer)
- Large page mapping
- NUMA interleaving
- Transparent page sharing only
Correct answer: Memory ballooning
VMware's balloon driver inflates inside the guest to reclaim idle pages and return them to the hypervisor without VM suspension.
Question 7: Which container networking mode gives a container its own network namespace with a virtual ethernet pair connected to the host?
- host
- none
- bridge (Correct answer)
- macvlan
Correct answer: bridge
Bridge mode creates a private network namespace for the container connected via a veth pair to the docker0 bridge on the host.
