Most Recent Juniper JN0-480 Exam Questions & Answers

A security policy is the feature that would be used to accomplish the task of controlling access to other virtual networks in the same routing zone using the Juniper Apstra UI. A security policy allows you to define rules that specify which traffic is allowed or denied between different virtual networks, IP endpoints, or routing zones. A security policy can be applied to one or more virtual networks in the same routing zone, and it can use various criteria to match the traffic, such as source and destination IP addresses, protocols, ports, or tags. A security policy can also support DHCP relay, which enables the forwarding of DHCP requests from one virtual network to another. The other options are incorrect because:

A) interface policy is wrong because an interface policy is a feature that allows you to configure the interface parameters for the devices in a blueprint, such as interface names, speeds, types, or descriptions. An interface policy does not affect the access control between different virtual networks in the same routing zone.

B) anti-affinity policy is wrong because an anti-affinity policy is a feature that allows you to prevent certain devices or logical devices from being placed in the same rack or leaf pair in a blueprint. An anti-affinity policy is used to enhance the availability and redundancy of the network, not to control the access between different virtual networks in the same routing zone.

C) routing policy is wrong because a routing policy is a feature that allows you to configure the routing parameters for the devices in a blueprint, such as routing protocols, autonomous system numbers, route filters, or route maps. A routing policy does not affect the access control between different virtual networks in the same routing zone, unless the routing policy is used to filter or modify the routes exchanged between different routing zones.Reference:

To implement remote user authentication for the role-based access control of your Apstra server, you can use one of the following methods: TACACS+, LDAP, or RADIUS. These are the protocols that Juniper Apstra supports to authenticate and authorize users based on roles assigned to individual users within an enterprise. You can configure the Apstra server to use one or more of these protocols as the authentication sources and specify the order of preference. You can also configure the Apstra server to use local user accounts as a fallback option if the remote authentication fails. The other options are incorrect because:

D) SAML is wrong because SAML (Security Assertion Markup Language) is not a supported protocol for remote user authentication for the role-based access control of your Apstra server. SAML is an XML-based standard for exchanging authentication and authorization data between different parties, such as identity providers and service providers. SAML is commonly used for web-based single sign-on (SSO) scenarios, but it is not compatible with the Apstra server.

E) Auth0 is wrong because Auth0 is not a protocol, but a service that provides authentication and authorization solutions for web and mobile applications. Auth0 is a platform that supports various protocols and standards, such as OAuth, OpenID Connect, SAML, and JWT. Auth0 is not a supported service for remote user authentication for the role-based access control of your Apstra server.Reference:

A cabling anomaly is an issue that occurs when the physical connections between the devices in the data center fabric do not match the expected connections based on the Apstra Reference Design. A cabling anomaly can cause problems such as incorrect routing, suboptimal traffic flow, or device isolation. To remediate the issue, you can use one or both of the following methods:

Manually edit the cabling map.This allows you to override the Apstra-generated cabling and specify the correct connections between the devices.You can use the Apstra UI or the Apstra CLI to edit the cabling map and apply the changes to the fabric12.

Have Apstra autoremediate the cabling map using LLDP.This allows Apstra to collect LLDP data from the devices and use it to update the cabling map automatically. LLDP is a protocol that allows devices to exchange information about their identity, capabilities, and neighbors.Apstra can use the LLDP data to detect and correct any cabling errors in the fabric34.Reference:

According to the Juniper documentation1, a configlet is a configuration template that augments Apstra's reference design with non-native device configuration. They consist of one or more generators. Each generator specifies a NOS type (config style), when to render the configuration, and CLI commands (and file name as applicable). Some applications for configlets include the following:

Syslog

SNMP access policy

TACACS / RADIUS

Management ACLs

Control plane policing

NTP

Username / password

Therefore, the correct answer is C and D. syslog configuration and NTP configuration. These are examples of non-native device configuration that can be added using a configlet. Static route configuration and policy configuration are not applicable in this scenario, because they are part of the reference design configuration that should not be replaced or modified by a configlet.Reference:Configlets (Datacenter Design),Configlet Examples (Design)

The deploy phase is the final step in the Juniper Apstra data center fabric design and deployment process. In this phase, you apply the Apstra-rendered configuration to the devices and verify the intent of the blueprint.Based on the web search results, we can infer the following actions are required during the deploy phase12:

Assign device profiles to the blueprint.This action associates a specific vendor model to each logical device in the blueprint. Device profiles contain extensive hardware model details, such as form factor, ASIC, CPU, RAM, ECMP limit, and supported features. Device profiles also define how configuration is generated, how telemetry commands are rendered, and how configuration is deployed on a device.Device profiles enable the Apstra system to render and deploy the configuration according to the Apstra Reference Design34.

Assign resources to the blueprint.This action allocates the physical devices, IP addresses, VLANs, and ASNs to the logical devices, networks, and routing zones in the blueprint. Resources can be assigned manually or automatically by the Apstra system.Assigning resources ensures that the blueprint has all the necessary elements to generate the configuration and deploy the fabric5.

Assign user roles to the blueprint.This action is not required during the deploy phase. User roles are defined at the system level, not at the blueprint level. User roles determine the permissions and access levels of different users in the Apstra system. User roles can be system-defined or custom-defined .

Assign interface maps to the blueprint.This action is not required during the deploy phase. Interface maps are defined at the design phase, not at the deploy phase. Interface maps are objects that map the logical interfaces of a logical device to the physical interfaces of a device profile. Interface maps enable the Apstra system to generate the correct interface configuration for each device in the fabric .Reference:
