Click to the Exhibit button.
Referring to the exhibit, which OpenStack service provides the UI shown in the exhibit?
- A . Nova
- B . Neutron
- C . Horizon
- D . Heat
Correct Answer: C
C
Explanation:
The UI shown in the exhibit is the OpenStack Horizon dashboard. Horizon is the web-based user interface (UI) for OpenStack, providing administrators and users with a graphical interface to interact with the cloud environment. Through Horizon, users can manage resources like instances, networks, and storage, which is evident in the displayed metrics (Instances, VCPUs, RAM) for the project.

Which two statements are correct about Network Functions Virtualization (NFV)? (Choose two.)
- A . the NFV framework explains how VNFs fits into the whole solution.
- B . The NFV Infrastructure (NFVI) is a component of NFV.
- C . The NFV Infrastructure (NFVI) is not a component of NFV.
- D . The NFV framework is defined by the W3C.
Correct Answer: A, B
A, B
Explanation:
Network Functions Virtualization (NFV) is a framework designed to virtualize network services traditionally run on proprietary hardware. It decouples network functions from dedicated hardware appliances and implements them as software running on standard servers or virtual machines.
