You want to keep virtual networks isolated from each other within the Juniper Apstra system.
In this scenario, what are three ways to accomplish this task? (Choose three.)
To keep virtual networks isolated from each other within the Juniper Apstra system, you can use one or more of the following methods:
Enable Security Policy for virtual networks in the same Routing Zone.This allows you to define rules that control the traffic flow between different virtual networks within the same routing zone. You can specify the source and destination virtual networks, the protocol, the port, and the action (allow or deny) for each rule.The security policy is applied on the ingress interface of the leaf devices1.
Use Connectivity Templates to block access within the same Routing Zone.This allows you to customize the connectivity between different racks within the same routing zone. You can create templates that define the link type, the routing protocol, and the access control list (ACL) for each rack pair.The ACL can be used to filter the traffic based on the source and destination IP addresses, the protocol, and the port2.
Put each network in different Routing Zones.This allows you to create logical boundaries between different virtual networks based on the route target (RT) values. A routing zone is a collection of virtual networks that share the same RT for importing and exporting routes.Virtual networks in different routing zones do not exchange routes with each other, unless you configure remote EVPN gateways to connect them3.Reference:

Exhibit.
Referring to the exhibit, how many broadcast domains will an Ethernet frame pass through when traversing the IP fabric from Server A to Server B?
Multilenancy for applications is achieved by creating virtual networks (VNs) within which construct?
According to the Juniper documentation1, a routing zone is an L3 domain, the unit of tenancy in multi-tenant networks. You create routing zones for tenants to isolate their IP traffic from one another, thus enabling tenants to re-use IP subnets. In addition to being in its own VRF, each routing zone can be assigned its own DHCP relay server and external system connections. You can create one or more virtual networks within a routing zone, which means a tenant can stretch its L2 applications across multiple racks within its routing zone. Therefore, the correct answer is D. routing zone. A routing zone is the construct within which you create virtual networks to achieve multitenancy for applications.Reference:Routing Zones
Which statement is true when onboarding a Juniper Networks device using a Juniper Apstra ZTP server?

Exhibit.
Which two statements ate correct about the graph query output shown in the exhibit? (Choose two.)
The graph query output shown in the exhibit is a JSON representation of an interface node and its properties in the Apstra graph database. Based on the output, we can infer the following statements:
The output shows a LAG connection.This is true because the interface node has a property calledlag_modewhich is set tolacp_active, indicating that the interface is part of a link aggregation group (LAG) that uses the Link Aggregation Control Protocol (LACP) to negotiate the link state and parameters12.
The switch in the output is a Juniper device.This is true because the interface node has a property calledif_namewhich is set toae2, indicating that the interface name follows the Juniper naming convention for aggregated Ethernet interfaces34.
The interface has an IP address assigned to it.This is false because the interface node has properties calledipv4_addrandipv6_addrwhich are both set tonull, indicating that the interface does not have any IPv4 or IPv6 address configured2.
The interface has tags assigned to it.This is false because the interface node has a property calledtagswhich is set tonull, indicating that the interface does not have any tags associated with it2.Reference:
