Juniper Cloud, Associate (JNCIA-Cloud) Sample Questions (Q33-Q38):

NEW QUESTION # 33
Click to the Exhibit button.

Referring to the exhibit, which OpenStack service provides the UI shown in the exhibit?

A. Heat
B. Neutron
C. Nova
D. Horizon

Answer: D

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.

NEW QUESTION # 34
What are the two characteristics of the Network Functions Virtualization (NFV) framework? (Choose two.)

A. It decouples the network control plane from the forwarding plane.
B. It implements virtualized network functions
C. It decouples the network software from the hardware.
D. It implements virtualized tunnel endpoints

Answer: B,C

Explanation:
Network Functions Virtualization (NFV) is a framework designed to virtualize network services traditionally run on proprietary hardware. NFV aims to reduce costs, improve scalability, and increase flexibility by decoupling network functions from dedicated hardware appliances. Let's analyze each statement:
A . It implements virtualized tunnel endpoints.
Incorrect: While NFV can support virtualized tunnel endpoints (e.g., VXLAN gateways), this is not a defining characteristic of the NFV framework. Tunneling protocols are typically associated with SDN or overlay networks rather than NFV itself.
B . It decouples the network software from the hardware.
Correct: One of the primary goals of NFV is to separate network functions (e.g., firewalls, load balancers, routers) from proprietary hardware. Instead, these functions are implemented as software running on standard servers or virtual machines.
C . It implements virtualized network functions.
Correct: NFV replaces traditional hardware-based network appliances with virtualized network functions (VNFs). Examples include virtual firewalls, virtual routers, and virtual load balancers. These VNFs run on commodity hardware and are managed through orchestration platforms.
D . It decouples the network control plane from the forwarding plane.
Incorrect: Decoupling the control plane from the forwarding plane is a characteristic of Software-Defined Networking (SDN), not NFV. While NFV and SDN are complementary technologies, they serve different purposes. NFV focuses on virtualizing network functions, while SDN focuses on programmable network control.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers NFV as part of its discussion on cloud architectures and virtualization. NFV is particularly relevant in modern cloud environments because it enables flexible and scalable deployment of network services without reliance on specialized hardware.
For example, Juniper Contrail integrates with NFV frameworks to deploy and manage VNFs, enabling service providers to deliver network services efficiently and cost-effectively.

NEW QUESTION # 35
You must provide tunneling in the overlay that supports multipath capabilities.
Which two protocols provide this function? (Choose two.)

A. VXLAN
B. MPLSoUDP
C. MPLSoGRE
D. VPN

Answer: A,B

Explanation:
In cloud networking, overlay networks are used to create virtualized networks that abstract the underlying physical infrastructure. To support multipath capabilities , certain protocols provide efficient tunneling mechanisms. Let's analyze each option:
A . MPLSoGRE
Incorrect: MPLS over GRE (MPLSoGRE) is a tunneling protocol that encapsulates MPLS packets within GRE tunnels. While it supports MPLS traffic, it does not inherently provide multipath capabilities.
B . VXLAN
Correct: VXLAN (Virtual Extensible LAN) is an overlay protocol that encapsulates Layer 2 Ethernet frames within UDP packets. It supports multipath capabilities by leveraging the Equal-Cost Multi-Path (ECMP) routing in the underlay network. VXLAN is widely used in cloud environments for extending Layer 2 networks across data centers.
C . VPN
Incorrect: Virtual Private Networks (VPNs) are used to securely connect remote networks or users over public networks. They do not inherently provide multipath capabilities or overlay tunneling for virtual networks.
D . MPLSoUDP
Correct: MPLS over UDP (MPLSoUDP) is a tunneling protocol that encapsulates MPLS packets within UDP packets. Like VXLAN, it supports multipath capabilities by utilizing ECMP in the underlay network. MPLSoUDP is often used in service provider environments for scalable and flexible network architectures.
Why These Protocols?
VXLAN: Provides Layer 2 extension and supports multipath forwarding, making it ideal for large-scale cloud deployments.
MPLSoUDP: Combines the benefits of MPLS with UDP encapsulation, enabling efficient multipath routing in overlay networks.
JNCIA Cloud Reference:
The JNCIA-Cloud certification covers overlay networking protocols like VXLAN and MPLSoUDP as part of its curriculum on cloud architectures. Understanding these protocols is essential for designing scalable and resilient virtual networks.
For example, Juniper Contrail uses VXLAN to extend virtual networks across distributed environments, ensuring seamless communication and high availability.
