The exhibit shows the border leaf receiving multiple routes via BGP from the external router, including 172.23.x/24 prefixes, and those routes appearing in the Finance VRF routing table. To stop these routes from being installed in the Finance table, you must change what the border leaf imports from that eBGP session. In Apstra, this control is implemented through a Routing Policy attached to the protocol session described by the connectivity template. By setting the Import Policy to accept default route only, Apstra renders Junos policy so that only 0.0.0.0/0 is imported into the VRF, while the 172.23.x/24 prefixes are rejected and therefore never installed in Finance.inet.0.

Option C is a common trap: the ''Expect Default IPv4 Route'' setting is an assurance expectation---it generates an expectation/anomaly if the default route is missing, but it does not change device configuration or filtering behavior. Export-policy changes (option D) would only affect what the border leaf advertises outbound to the external router, not what it learns inbound. Aggregation (option A) does not prevent installation of the specific learned /24s; it changes advertisement behavior rather than import filtering. The correct fix is to tighten the import policy on that external eBGP session.

In Juniper Apstra, a widget is a graphical element that displays data from an intent-based analytics (IBA) probe. A widget can be used to monitor different aspects of the network and raise alerts to any anomalies. A widget can be viewed by itself or added to an analytics dashboard.A dashboard is a collection of widgets that can be customized and organized according to the user's preference1.

The main dashboard in Juniper Apstra is the blueprint dashboard, which is the default view that shows the network information and configuration for the active blueprint. A blueprint is a logical representation of the network design and intent.The blueprint dashboard can display the system-generated dashboards, the user-generated dashboards, and the individual widgets that are relevant to the network2.

To make a widget appear on the main dashboard in Juniper Apstra, the user needs to set the Default toggle switch to On for the desired widget. This will add the widget to the blueprint dashboard, where it can be viewed along with other network information.The user can also remove the widget from the blueprint dashboard by setting the Default toggle switch to Off for the widget3. Therefore, the statement D is correct in this scenario.

The following three statements are incorrect in this scenario:

When creating the widget, select the Add to Blueprint Dashboard option. This is not true, because there is no such option when creating a widget in Juniper Apstra.The user can only select the widget type, the probe, and the display mode when creating a widget4.To add the widget to the blueprint dashboard, the user needs to set the Default toggle switch to On for the widget after creating it3.

On the blueprint dashboard, click on the Add Widget option. This is not true, because there is no such option on the blueprint dashboard in Juniper Apstra.The user can only view, edit, or delete the existing widgets and dashboards on the blueprint dashboard2.To add a widget to the blueprint dashboard, the user needs to set the Default toggle switch to On for the widget from the widgets table view3.

Widgets automatically appear on the blueprint dashboard. This is not true, because widgets do not automatically appear on the blueprint dashboard in Juniper Apstra.The user needs to manually add the widgets to the blueprint dashboard by setting the Default toggle switch to On for the widgets that they want to see on the blueprint dashboard3.The only exception is the widgets that are part of the system-generated dashboards, which are automatically created and added to the blueprint dashboard based on the state of the active blueprint2.

In EVPN multihoming, the Ethernet Segment Identifier (ESI) is the mandatory identifier used to represent a multihomed Ethernet segment---for example, a server or downstream switch that is dual-homed to two leaf devices using a single logical LAG/port-channel. By assigning the same ESI to the participating leaf-facing interfaces, the fabric recognizes those links as belonging to one Ethernet segment and can apply EVPN multihoming procedures consistently across the pair.

A key outcome of EVPN multihoming is loop prevention for multi-attached Layer 2 domains. EVPN uses the Ethernet segment concept (identified by the ESI) along with Designated Forwarder (DF) election to ensure that only the appropriate device forwards BUM (broadcast, unknown unicast, multicast) traffic toward the multihomed segment, avoiding duplicate forwarding and L2 loops. In addition, ESI-based multihoming supports resilient forwarding behavior during failures (for example, link or node loss) while maintaining correct advertisement and convergence in the EVPN control plane.

Therefore, among the provided options, the purpose that best matches how ESI is used operationally is to prevent loops within a LAG/multihomed connection, which is fundamental to EVPN-VXLAN data center designs on Junos v24.4 leaf devices and is also explicitly supported by Apstra when modeling ESI-based dual-homing.

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:

In Apstra 5.1, capacity planning based on pre-built time-series telemetry (such as link utilization trends) is part of Intent-Based Analytics (IBA). IBA is where Apstra ingests streaming telemetry from fabric devices, stores it as time-series data, and presents it through built-in analytics views (dashboards/widgets) and probes. Because the question specifically calls out ''pre-built time series information regarding link utilization,'' the correct UI location is the Analytics top-level tab within the blueprint.

The Active tab is primarily oriented to operational state and day-2 workflows (for example, viewing live state, queries, and device-level operational views). The Staged tab is where you modify intent (physical/virtual design, policies, catalog items) prior to committing and deploying. The Dashboard provides a high-level blueprint overview and navigation, but the drill-down and time-series analytics views that support trending and capacity analysis are accessed via Analytics.

In an EVPN-VXLAN fabric using Junos v24.4, link utilization time-series is particularly valuable because underlay congestion can degrade overlay performance (BGP convergence behavior, ECMP distribution effectiveness, and endpoint experience). Apstra's Analytics tab centralizes these metrics so operators can evaluate utilization baselines, identify sustained hot links, and support proactive actions (rebalancing, adding capacity, or adjusting design intent) without relying on ad-hoc per-device CLI polling.

Juniper Apstra provides four system-defined user roles that are available in the Apstra GUI environment.They are:administrator,device_ztp,viewer, anduser1. Based on the web search results, we can infer the following statements:

viewer: This role includes permissions to only view various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others.Users with this role cannot create, edit, or delete any element12.

user: This role includes permissions to view and edit various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others.Users with this role cannot create or delete any element12.

authorized: This is not a system-defined user role in Juniper Apstra.It is a term used to describe users who have been authenticated by an external system, such as LDAP, Active Directory, TACACS+, or RADIUS3.

root: This is not a system-defined user role in Juniper Apstra. It is a term used to describe the superuser account on a Linux system, which has full access to all commands and files. Creating a user in the Apstra GUI does not provide that user access to the Apstra platform via SSH.To access the Apstra platform via SSH, you must create a local Linux system user4.Reference:
