Demo Questions
Question 1
Which of the following best describes the reason for CPU pinning?
- To ensure that a VM is assigned to high performance CPU cores.
- To ensure that a VM’s CPU cores area all allocated on the same NUMA node.
- To ensure that a VM is assigned to a compute node with adequate resources.
- To ensure that a VM is assigned a sufficient number of CPU cores.
Correct answer: A
Question 2
Which of the following describes the benefit of using huge pages?
- Huge pages improves the performance of mapping virtual memory addresses to physical memory addresses.
- Huge pages improves the performance of decreasing the number of memory accesses involved in a page table walk.
- Huge pages improves the performance of swapping by increasing the number of TLB cache hits.
- Huge pages improves the performance of swapping by optimizing the loading of pages to main memory.
Correct answer: C
Explanation:
Question 3
Which of the following describes the 2N model for VM redundancy?
- There is one active VM and one standby VM that takes over if the active VM fails.
- Thera are N active VMs and a pool of standby VMs that can take over if one or more active VMs fail.
- There are N active VMs, each one paired with a standby VM that takes over if its active VM fails.
- There are 2N active VMs deployed to support a service that needs N active VMs, with extra capacity in case one or more VMs fail.
Correct answer: C
Question 4
Which of the following statements about interface redundancy with OVS is FALSE?
- OVS provides redundancy through a Linux bonded interface on the hypervisor.
- Guest VMs have two virtual NICs connected to OVS through a Linux bridge.
- Ethernet frames are sent between the redundant interfaces to verify connectivity.
- OVS connects to two physical ports connected to distinct leaf switches.
Correct answer: C
Question 5
Which of the following OpenStack projects provides networking services to VMs?
- Neutron
- Nova
- Keystone
- Horizon
Correct answer: A
Question 6
Which of the following provides the virtual hardware environment for the guest OS on a Linux system?
- libvirt
- QEMU
- virsh
- ESXi
Correct answer: B
Question 7
Which of the following networks is NOT required by CMM?
- An OAM network for CMM management
- An internal network for inter-VM communication
- A data switch fabric for carrying 3G data plane traffic between IPDS and IPPS.
- An external network for communication with external entities.
Correct answer: D
Question 8
Which of the following statements regarding CMM internal IP management (IIPM) is FALSE?
- IIPM manages reachability between CMM VNF components.
- IIPM monitors connectivity over two vNIC ports when two internal networks are used.
- With IIPM, broadcast messages are sent periodically between VMs.
- IIPM uses BFD to provide a fast switchover in case of an internal reachability failure.
Correct answer: C
Question 9
Which of the following statements regarding the CMM virtual network function (VNF) architecture is FALSE?
- The CMM VNF consists of multiple virtual machines that run on top of a cloud infrastructure.
- The load balancer layer terminates external logical interfaces.
- The transaction layer processes 3G user plane.
- The CMM VNF follows a multi-tier architecture where each tier can scale independently.
Correct answer: A
Question 10
Which of the following statements regarding CMM log management is FALSE?
- VMs push logs to the Kafka pipeline.
- The event consumer in NECC retrieves the logs from Kafka.
- Various log files generated automatically in CMM.
- A log query can be created to retrieve logs from the database based on a time range.
Correct answer: B
