NEW QUESTION # 29
What are two system-defined user roles that are available in Juniper Apstra? (Choose two.)
- A. root
- B. viewer
- C. user
- D. authorized
Answer: B,C
Explanation:
Juniper Apstra provides four system-defined user roles that are available in the Apstra GUI environment. They are: administrator, device_ztp, viewer, and user1. 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:

NEW QUESTION # 30
Which Root Cause Identifier is currently supported in Juniper Apstra software?
- A. BGP
- B. Connectivity
- C. ESI imbalance
- D. Virtual network
Answer: B
Explanation:
In Juniper Apstra 5.1, Root Cause Identification (RCI) is implemented with a currently supported model focused on connectivity. Practically, this means RCI is designed to take telemetry and state learned from the fabric (for example, interface operational status, LLDP neighbor information, and routing session status) and correlate those signals to determine the most likely underlying cause of a connectivity-impacting event. Within an EVPN-VXLAN IP fabric, many operational symptoms can appear similar at the service layer (endpoints cannot reach each other, routes disappear, overlays degrade), but RCI narrows the problem by correlating evidence across the underlay and control plane.
The "connectivity" RCI model targets common failure scenarios that directly break device-to-device reachability, such as a broken link, a miscabled link (wrong LLDP neighbors), or an operator-disabled interface. These conditions often cascade into higher-level symptoms, including BGP sessions dropping over affected links. With Junos v24.4-based leaf-spine fabrics, maintaining stable underlay connectivity is foundational for EVPN signaling and VXLAN forwarding; therefore, Apstra's connectivity-focused RCI helps operators rapidly isolate whether the primary fault lies in physical adjacency, cabling/neighbor correctness, or administrative shutdown-reducing mean time to repair by pointing to the most probable root cause rather than only listing alarms.
NEW QUESTION # 31
Which two statements are correct about Juniper Apstra reference designs? (Choose two.)
- A. The Freeform reference design requires knowledge of device CLI.
- B. The data center reference design requires knowledge of device CLI.
- C. The Freeform reference design supports only Junos devices.
- D. The data center reference design supports only Junos devices.
Answer: A,C
Explanation:
Apstra 5.1 provides multiple reference designs that define how intent is modeled and how configuration is produced. In the Freeform reference design, the network designer is responsible for creating and validating the device configurations using constructs such as device contexts, property sets, and config templates. Because configuration is authored rather than generated from a fixed data-center abstraction set, Freeform inherently requires practical knowledge of the device's configuration model and operational behavior-on Juniper platforms, that means being comfortable with Junos-style configuration and show/verification workflows. This makes statement A correct.
Freeform in Apstra 5.1 is also limited to Juniper devices (Junos and Junos Evolved families). In other words, Freeform blueprints do not provide multi-vendor device onboarding and deployment in that reference design at this software level. That makes statement D correct as written in the question's choices.
By contrast, the data center reference design in Apstra 5.1 is not limited to Junos-only device families; Apstra qualifies multiple NOS families for data center operation via device profiles and packages, and it renders intent accordingly. Therefore statement B is not correct. Finally, while CLI knowledge is always useful for troubleshooting, the data center reference design does not fundamentally require an operator to hand-author device CLI to deploy a standards-based EVPN-VXLAN fabric; that's one of the core benefits of the intent-based data center reference design.

NEW QUESTION # 32
You are building a blueprint using Juniper Apstra and must change the cable map to match the physical environment.
Where in the blueprint UI is this task accomplished?
- A. Staged --> Connectivity Templates
- B. Active --> Connectivity Templates
- C. Active --> Physical --> Links
- D. Staged --> Physical --> Links
Answer: D
Explanation:
To modify the cable map in Juniper Apstra so it matches the actual physical environment, you must do it in the Staged → Physical → Links section of the blueprint UI. Changes made in the staged view allow adjustments before committing them to the active fabric.
NEW QUESTION # 33
You have a configuration deviation in the Juniper Apstra dashboard.
What does this anomaly indicate in this scenario?
- A. A device cannot support a configuration command sent by the system.
- B. A device is ready to be configured by the system.
- C. A device's configuration has been changed using a method outside of Apstra.
- D. A device's configuration has been updated by the server.
Answer: C
Explanation:
A configuration deviation anomaly in the Juniper Apstra dashboard indicates that the running configuration on a device does not match the intended configuration (golden config) maintained by Apstra. This typically occurs when someone makes changes directly on the device using CLI or another management tool, bypassing Apstra's intent-based control.
NEW QUESTION # 34
You are using Juniper Apstra to design a data center fabric. In this scenario, which object type associates a specific vendor model to a logical device?
- A. device profiles
- B. templates
- C. interface map
- D. agent profiles
Answer: A
Explanation:
Device profiles are objects that associate a specific vendor model to a logical device in Juniper Apstra. 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 Design.
NEW QUESTION # 35
When editing a device configuration to install some manual changes, which procedure should be followed?
- A. Edit the pristine configuration of the device.
- B. Delete the device from the Juniper Apstra system, change the configuration, then re-import the device.
- C. Edit the configuration on the device directly by the CLI; the changes will automatically be adjusted in the Juniper Apstra configuration
- D. Add a persistent change to a device configuration with a configlet.
Answer: D
Explanation:
A configlet is a small piece of configuration that can be applied to a device or a group of devices to make persistent changes that are not overwritten by Apstra. Configlets can be used to install manual changes that are not part of the Apstra rendered configuration, such as custom commands, scripts, or features. Configlets can be created, edited, and deleted from the Apstra GUI or CLI.
NEW QUESTION # 36
What are three port group roles that you are allowed to assign to a logical device? (Choose three.)
- A. empty
- B. generic
- C. root
- D. spine
- E. leaf
Answer: B,D,E
Explanation:
When assigning port group roles to a logical device in Juniper Apstra, the valid roles you can assign include:
Leaf - for ports that connect to servers or access layer devices.
Spine - for ports that connect to spine or core switches.
Generic - for ports that connect to systems not playing a fabric role (e.g., firewalls, external routers, or appliances).
NEW QUESTION # 37
You are asked to deploy a collapsed fabric architecture. Which two statements are correct about this deployment? (Choose two.)
- A. All EVPN-VXLAN overlay functions are provided by the leaf devices.
- B. Top-of-rack switches provide VXLAN support.
- C. Top-of-rack switches are full-mesh connected.
- D. Leaf devices are full-mesh connected.
Answer: A,D
Explanation:
In Apstra, a collapsed fabric (also described as "spineless") consolidates traditional fabric tiers so that the primary fabric devices perform combined roles. Instead of a dedicated spine tier providing transit between leafs, the fabric is formed by leaf devices connected directly to each other using mesh links. This means a collapsed fabric uses a full-mesh topology at the leaf level, replacing the usual leaf-to-spine connections found in a three-stage Clos. Therefore, the statement that leaf devices are full-mesh connected is correct.
Because the collapsed fabric devices serve the fabric roles, they also provide the EVPN-VXLAN overlay functions (VTEP behavior, EVPN control-plane participation, and VXLAN encapsulation/decapsulation) necessary for tenant segmentation and service delivery. Juniper's collapsed fabric validated designs further describe the collapsed fabric switches as serving all fabric roles (including border-leaf behaviors when external connectivity is required), reinforcing that overlay functions reside on these fabric leaf devices.
The remaining statements are not generally true for the collapsed fabric definition. Top-of-rack (access) switches-when present in certain collapsed designs-are not defined by default as full-mesh connected, and VXLAN support is not a requirement for those TOR/access switches unless the specific architecture explicitly uses them as VTEPs. The defining characteristics are the consolidated fabric roles and the leaf-level full-mesh.

NEW QUESTION # 38
Which two statements about VXLAN VNIs are correct? (Choose two.)
- A. VNIs are alphanumeric values.
- B. VNIs can have over 16 million unique values.
- C. VNIs identify a collision domain.
- D. VNIs identify a broadcast domain
Answer: B,D
Explanation:
VXLAN VNIs are virtual network identifiers that are used to identify and isolate Layer 2 segments in the overlay network. VXLAN VNIs have the following characteristics:
VNIs can have over 16 million unique values. This is because VXLAN VNIs are 24-bit fields that can range from 4096 to 16777214, according to the VXLAN standard. This allows VXLAN to support a large number of Layer 2 segments and tenants in the network. VNIs identify a broadcast domain. This is because VXLAN VNIs are used to group the end hosts that belong to the same Layer 2 segment and can communicate with each other using VXLAN tunnels. The VXLAN tunnels are established using the VTEP information that is distributed by EVPN. The VTEPs are VXLAN tunnel endpoints that perform the VXLAN encapsulation and decapsulation.
The VXLAN tunnels preserve the Layer 2 semantics and support the broadcast, unknown unicast, and multicast traffic within the same VNI.

Answer: A
NEW QUESTION # 40
What are three phases of the Juniper Apstra data center life cycle? (Choose three.)
- A. configuration
- B. deployment
- C. installation
- D. design
- E. operational phase
Answer: B,D,E
Explanation:
Apstra organizes the data center life cycle into distinct phases that align with intent-based networking principles:
- Design: Define the architecture, templates, logical devices, racks, and connectivity.
- Deployment: Instantiate the design into a real fabric, assign systems, push configurations.
- Operational Phase: Monitor, manage, and analyze the running network using telemetry, analytics, and automation tools.
NEW QUESTION # 41
What is the purpose of an interface map in Juniper Apstra?
- A. An interface map specifies the number of ports and the port speeds of a logical device
- B. An interface map specifies a connection between the interfaces of two devices.
- C. An interface map associates a logical device with a device profile.
- D. An interface map specifies the connections between racks in a template.
Answer: B
Explanation:
An interface map is a configuration template that maps interfaces between logical devices and physical hardware devices (represented with device profiles) while adhering to vendor specifications. An interface map specifies a connection between the interfaces of two devices, such as a leaf and a spine, a leaf and a server, or a leaf and an external gateway. An interface map can also specify port transformations, such as breaking out a 40 GbE port into four 10 GbE ports, or disabling unused ports. An interface map can be used to achieve the intended network configuration rendering and to enable features such as LAG, ESI-LAG, or MLAG.
NEW QUESTION # 42
Referring to the exhibit, which statement is correct?
- A. The red-striped primitives indicate that they are incompatible with the connectivity template design.
- B. The red-striped primitives indicate that further configuration is required.
- C. The gray-solid primitives indicate that they ate incompatible with the connectivity template design.
- D. The gray-solid primitives indicate further configuration is requited.
Answer: B
Explanation:
A connectivity template is a set of configuration parameters that can be applied to a device or a group of devices in a blueprint. A blueprint is a logical representation of the network design and intent. A primitive is a basic unit of configuration that can be added to a connectivity template. A primitive can be a link, a peering, a policy, or a service. In the exhibit, the red-striped primitives indicate that further configuration is required for them to be compatible with the connectivity template design. The red stripes mean that the primitive is incomplete or invalid, and it needs to be edited or deleted. For example, the IP Link primitive needs to have the interface name and IP address specified for each end of the link.
NEW QUESTION # 43
What are three valid resource types supported within Juniper Apstra? (Choose three.)
- A. integer pools
- B. routing zone pools
- C. VNI pools
- D. ASN pools
- E. interface pools
Answer: A,C,D
Explanation:
Juniper Apstra supports various resource types for managing and assigning infrastructure values across blueprints. Three valid resource types are:
- Integer Pools - Used for assigning numeric values like VLAN IDs.
- VNI Pools - Used to assign unique VXLAN Network Identifiers to virtual networks.
- ASN Pools - Used to assign Autonomous System Numbers for BGP sessions.
Routing zone pools and interface pools are not valid resource types in Apstra. Routing zones and interfaces are configured differently within the blueprint structure.
NEW QUESTION # 44
You are assigning managed devices to a blueprint, for a fully functioning IP fabric.
In the Juniper Apstra UI, which mode should you choose for this task?
- A. Deploy
- B. Ready
- C. Not Set
- D. Drain
Answer: A
Explanation:
When assigning managed devices to a blueprint in Juniper Apstra for a fully functioning IP fabric, the correct mode is Deploy. This ensures that the devices are active participants in the fabric, receiving the intended configuration and forwarding traffic as designed.
NEW QUESTION # 45
In Juniper Apstra, which statement is correct?
- A. VMware anomaly detection requires a vCenter server configured under External Systems
- B. VMware anomaly detection is on by default.
- C. VMware anomaly detection requires a VMware hypervisor with exports enabled.
- D. VMware anomaly detection requires an Apstra server running on VMware.
Answer: A
Explanation:
VMware anomaly detection is a feature of Apstra that provides visibility and validation of the virtual network settings and the physical network settings in a VMware vSphere environment. To enable this feature, Apstra requires a connection to a vCenter server that manages the ESX/ESXi hosts and the VMs connected to the Apstra-managed leaf switches. The vCenter server must be configured under External Systems in the Apstra web interface, and the vCenter integration must be staged and committed in the blueprint. This allows Apstra to collect information about VMs, ESX/ESXi hosts, port groups, and VDS, and to flag any inconsistencies or mismatches that might affect VM connectivity.
