The questions for JN0-480 were last updated On May. 06, 2024

Question #1

What is the purpose of using a routing zone inside Juniper Apstra software?

Reveal Solution Hide Solution
Correct Answer: D

According to the Juniper documentation1, a routing zone is an L3 domain, the unit of tenancy in multi-tenant networks. You create routing zones for tenants to isolate their IP traffic from one another, thus enabling tenants to re-use IP subnets. In addition to being in its own VRF, each routing zone can be assigned its own DHCP relay server and external system connections. You can create one or more virtual networks within a routing zone, which means a tenant can stretch its L2 applications across multiple racks within its routing zone. For virtual networks with Layer 3 SVI, the SVI is associated with a Virtual Routing and Forwarding (VRF) instance for each routing zone isolating the virtual network SVI from other virtual network SVIs in other routing zones. Therefore, the correct answer is D. A routing zone is used to enable the communication between two VNIs within a VRF. A routing zone is not used for L4-L7 inspection, securing routing protocols, or requiring firewalls. Those are not the purposes of a routing zone in Juniper Apstra software.Reference:Routing Zones


Question #2

What is the purpose of a Juniper Apstra rack?

Reveal Solution Hide Solution
Correct Answer: B

A Juniper Apstra rack is a physical entity that contains one or more network devices, such as leaf nodes, access switches, or generic systems. A rack is used to organize and manage the network devices in the Apstra software application. A rack has the following characteristics:

It stores information on how leaf nodes connect to generic devices. This is because a rack can include generic systems, which are devices that are not managed by Juniper Apstra, but are connected to the network. A generic system can be a server, a firewall, a load balancer, or any other device that has a network interface.A rack stores the information on how the leaf nodes, which are the devices that provide access to the end hosts, connect to the generic devices, such as the port number, the link speed, the LAG mode, and the roles1.

It has a rack type, which defines the type and number of leaf devices, access switches, and/or generic systems that are used in the rack. A rack type is a resource that is created in the data center design phase, and it does not specify the vendor or the model of the devices.A rack type can be predefined or custom-made, and it can be used to create multiple racks with the same structure and configuration2.

It has a rack build, which assigns the specific vendor and model of the devices to the rack. A rack build is created in the staged phase, and it uses the rack type as a template.A rack build can also assign the resources, such as the IP addresses, the ASNs, and the VNIs, to the devices in the rack3.

It has a rack deployment, which applies the network configuration and services to the devices in the rack. A rack deployment is performed in the active phase, and it uses the rack build as a reference.A rack deployment can also monitor the network performance and compliance of the devices in the rack4.

The following three statements are incorrect in this scenario:

It stores information on how pods connect to super spines. This is not true, because a rack does not store any information on the pod or the super spine level of the network. A pod is a cluster of leaf and spine devices that form a 3-stage Clos topology, and a super spine is a device that connects multiple pods in a 5-stage Clos topology.A rack only stores information on the leaf and the access level of the network1.

It stores IP address and ASN pool information. This is not true, because a rack does not store any information on the IP address and ASN pools. IP address and ASN pools are resources that are created in the data center design phase, and they contain a range of IP addresses and ASNs that can be assigned to the devices and the virtual networks.A rack only uses the IP address and ASN pools to assign the resources to the devices in the rack build2.

It stores device port data rates and vendor information. This is not true, because a rack does not store any information on the device port data rates and vendor information. The device port data rates and vendor information are specified in the rack build, which assigns the specific vendor and model of the devices to the rack.A rack only uses the rack build to apply the network configuration and services to the devices in the rack deployment3.

Question #4

Which statement is correct about making changes to a predefined device profile in Juniper Apstra?

Reveal Solution Hide Solution
Correct Answer: A

According to the Juniper documentation1, a predefined device profile is a configuration template that is shipped with Apstra software and supports most qualified Juniper devices. A predefined device profile cannot be changed, since any changes would be discarded and overwritten when you upgrade the Apstra server version. If you want to customize a predefined device profile, you can clone and edit it instead. Therefore, the correct answer is A. The changes you make to a predefined device profile will be discarded and overwritten when upgrading the Apstra server version.Reference:Edit Device Profile | Apstra 4.2 | Juniper Networks


Question #5

Which two statements are correct regarding a pristine configuration in Juniper Apstra? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, C

A pristine configuration in Juniper Apstra is the configuration file that is used to onboard a device into the Apstra software application.A pristine configuration contains the minimum settings that are required for the device to communicate with the Apstra server, such as the hostname, management IP address, username, password, and SSH key1. A pristine configuration has the following characteristics:

It is the configuration file placed on the device when decommissioning the device. This is because when a device is decommissioned from the Apstra software application, it is reverted back to its pristine configuration, which removes all the network configuration and services that were applied by the Apstra software application.This allows the device to be reused or repurposed for another network2.

It is the configuration file on a device before acknowledgment in Apstra. This is because when a device is onboarded into the Apstra software application, it is initially in the discovery state, which means that the device is discovered by the Apstra server, but not yet acknowledged by the user. In the discovery state, the device has the pristine configuration, which can be viewed and edited by the user.Once the user acknowledges the device, the device moves to the deployed state, which means that the device is ready to receive the network configuration and services from the Apstra software application3.

The following two statements are incorrect in this scenario:

It is the device's currently active configuration. This is not true, because the pristine configuration is not the device's currently active configuration, unless the device is in the discovery state or the decommissioned state.In the deployed state, the device's currently active configuration is the network configuration and services that are applied by the Apstra software application, which are based on the blueprint and the intent3.

It is the device's previously active configuration. This is not true, because the pristine configuration is not the device's previously active configuration, unless the device is in the decommissioned state. In the discovery state, the pristine configuration is the device's initial configuration, which may or may not be the same as the device's previous configuration before being onboarded into the Apstra software application.In the deployed state, the device's previously active configuration is the network configuration and services that were applied by the Apstra software application before the last commit3.
