Juniper JN0-480 Exam With Confidence Using Practice Dumps

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. References:

Device A serves as a spine in an IP fabric. An IP fabric is a network architecture that uses a spine-leaf topology to provide high performance, scalability, and reliability for data center networks. A spine-leaf topology consists of two layers of devices: spine devices and leaf devices. Spine devices are the core devices that interconnect all the leaf devices using equal-cost multipath (ECMP) routing. Leaf devices are the edge devices that connect to the servers, storage, or other network devices. In the exhibit, Device A is connected to four leaf devices using multiple links, which indicates that it is a spine device. The other options are incorrect because:

• A. leaf is wrong because a leaf device is an edge device that connects to the servers, storage, or other network devices. In the exhibit, Device A is not connected to any servers, storage, or other network devices, but only to four leaf devices, which indicates that it is not a leaf device.
• C. super spine is wrong because a super spine device is a higher-level device that interconnects multiple spine devices in a large-scale IP fabric. A super spine device is typically used when the number of leaf devices exceeds the port density of a single spine device. In the exhibit, Device A is not connected to any other spine devices, but only to four leaf devices, which indicates that it is not a super spine device.
• D. server is wrong because a server device is a compute or storage device that connects to a leaf device in an IP fabric. A server device is typically the end host that provides or consumes data in the network. In the exhibit, Device A is not connected to any leaf devices, but only to four leaf devices, which indicates that it is not a server device. References:

Referring to the exhibit, the image shows a user interface of the Juniper Apstra software application, which is used for network management and configuration. The image shows the Virtual Networks table under the Resources menu, which displays the details of the VLANs and VXLANs in the network. The table has 11 columns, but only 9 are visible in the image. The other two columns are IPv6 Connectivity and IPv6 Subnet, which are hidden by default. To display the IPv6 subnets for all of the listed VXLANs, the user needs to select Columns, then select IPv6 Subnet. This will show the IPv6 Subnet column in the table, which will display the IPv6 addresses assigned to the VXLANs from the IPv6 pools. For more information, see Virtual Networks (Resources). References:
