What are three phases of the Juniper Apstra data center life cycle? (Choose three.)
Correct Answer: B,D,E
Juniper Apstra describes data center fabric management as a full lifecycle that spans three core phases: Design (Day 0), Deployment (Day 1), and Operations (Day 2). These phases map directly to how Apstra applies intent-based networking to a data center fabric. In the Design phase, you model the intended architecture-templates (3-stage or 5-stage), rack types, logical devices, interface maps, resource pools, and high-level constructs such as routing zones and virtual networks. The objective is to capture intent in a vendor-agnostic way while ensuring consistency and validation before anything is pushed. In the Deployment phase, Apstra turns the modeled intent into device-level implementation. This includes onboarding systems, assigning device profiles, allocating resources, rendering configurations, and pushing the resulting configuration to switches so the IP fabric becomes operational. This is where Junos v24.4 leaf/spine nodes receive underlay and overlay configuration generated from the blueprint. In the Operational phase, Apstra continuously validates the running network against intent using telemetry and analytics (IBA), detects deviations and anomalies, supports maintenance workflows (such as drain), and provides troubleshooting tools (queries, time-series utilization, and configuration compliance). "Configuration" and "installation" are activities that occur within the lifecycle, but the lifecycle phases themselves are Design, Deployment, and Operations.
Question 57
Which element of an intent-based analytics (IBA) probe is used to specify the database objects to which the probe will apply?
Correct Answer: B
In Juniper Apstra's Intent-Based Analytics (IBA), a graph query defines the database objects and relationships that the probe will evaluate. This query specifies the exact scope of data (such as nodes, links, or metrics) to which the probe applies, enabling precise monitoring and validation against the intended state.
Question 58
At which point in the design process does the operator choose IPv4 or IPv6 for a spine-and-leaf link underlay type?
Correct Answer: B
In Juniper Apstra, the choice of IPv4 or IPv6 for the spine-and-leaf underlay is made during blueprint creation. At this stage, the operator defines the fundamental design parameters of the fabric, including the underlay addressing type, which then determines how IP pools are allocated to inter-device links.
Question 59
Which Juniper Apstra object defines the overall fabric design, including spine count, rack types, and their connectivity, before a blueprint is created?
Correct Answer: C
A Template in Juniper Apstra defines the overall logical design of the fabric, combining Rack Types with information such as the number of spine devices and the fabric topology (for example, a 3-stage or 5-stage Clos). Once a Template is defined, it can be used to instantiate a Blueprint, which becomes the active, deployable representation of the design.
Question 60
The 10.100.0.0/16 route is being advertised into your BGP IP fabric. ECMP load balancing has been properly enabled on all devices. In this scenario, how many routes will the leaf device in AS 65000 receive for the 10.100.0.0/16 prefix?
Correct Answer: A
The leaf device in AS 65000 will receive three routes for the 10.100.0.0/16 prefix, one from each spine device in AS 65001, AS 65002, and AS 65003. Since ECMP load balancing is enabled, the leaf device will install all three routes in its routing table and distribute the traffic among them.
