1. 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.

2. Which of the following OpenStack projects provides networking services to VMs?

Neutron

Nova

Keystone

Horizon

3. Which of the following statements about SR-IOV is FALSE?

VMs using OVS and SR-IOV can be instantiated on the same compute node.

SR-IOV offers comparable performance to non-visualized hardware.

The VM must be attached to the PF to achieve highest performance.

Using SR-IOV restricts VM mobility.

4. 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 page swapping by increasing the number of TLB cache hits.

Huge pages improves the performance of page swapping by optimizing the loading of pages to main memory.

5. 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.

6. What is the main benefit of splitting the core network into separate user-plane and control-plane nodes?

Independent configuration of user-plane and control-plane nodes

Independent scaling of user-plane and control-plane nodes

User of a shared data repository for storing user states.

Creation of networks with isolated properties over a common infrastructure

7. Which of the following best describes the reason for CPU pinning?
