NEW QUESTION # 68
What is the purpose of an interface map in Juniper Apstra?
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 # 69
You have a virtual network that needs controlled access to other virtual networks in the same routing zone. Using the Juniper Apstra Ul. which feature would be used to accomplish this task?
Answer: B
Explanation:
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.

NEW QUESTION # 70
Using Juniper Apstra. which component is defined in a template?
Answer: A
Explanation:
A template is a configuration template that defines a network's policy intent and structure. A template can be either rack-based or pod-based, depending on the type and number of racks and pods in the network design. A template includes the following details:
Policies: These are the parameters that apply to the entire network, such as the overlay control protocol, the ASN allocation scheme, and the underlay type.
Structure: This is the physical layout of the network, such as the type and number of racks, pods, spines, and leaves. The structure also defines the leaf-to-spine interconnection, which is the number and type of links between the leaf and spine devices. The leaf-to-spine interconnection can be either single or dual, depending on the redundancy and bandwidth requirements.
Therefore, the correct answer is A. the leaf-to-spine interconnection. This is a component that is defined in a template, as it determines the physical connectivity of the network. The speed of the links, the number of spine devices, and the definition of IP pools are not components that are defined in a template, as they are either derived from the device profiles, the resource pools, or the blueprint settings.
NEW QUESTION # 71
What are three valid resource types supported within Juniper Apstra? (Choose three.)
Answer: A,C,E
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 # 72
You are creating a new security policy using Juniper Apstra.
Referring to the exhibit, which application point should you select to allow or deny traffic to or from a particular VRF?
Answer: D
Explanation:
In Apstra 5.1, multitenancy is modeled using routing zones, which map directly to the network operating system concept of a VRF. A VRF is an isolated Layer 3 routing instance with its own routing table and forwarding context, and Apstra's routing zone is the intent-based abstraction used to define and manage that isolation consistently across the fabric. Therefore, if your goal is to allow or deny traffic to or from a particular VRF, you must select Routing Zone as the security policy application point.
This choice enables you to express policy at the tenant boundary (VRF boundary) rather than at a single segment boundary. In EVPN-VXLAN data center fabrics, a tenant VRF commonly contains multiple virtual networks (VXLAN segments) and their associated IRB gateways on the leaf switches. Applying policy at the routing-zone level allows Apstra to compile intent and deploy enforcement consistently where traffic enters or exits that VRF context-typically as ACL constructs rendered as Junos firewall filters on the appropriate interfaces (for example, IRB interfaces for east-west controls or border interfaces for north-south controls).
By contrast, selecting Virtual Network targets a single segment (not the whole VRF), and Internal/External Endpoint targets specific endpoints or endpoint groups rather than the VRF-wide policy boundary. Hence, Routing Zone is the correct application point when policy scope is the VRF.
