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.)
Explanation:
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:

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?
Explanation:
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?
Explanation:
The ztp.Json file on the Apstra ZTP server contains the configuration parameters for each device that is onboarded using ZTP. One of the parameters is the State, which can be one of the following values:init,ready,in_progress,done,error, ordisabled. The State indicates the current status of the device in the ZTP process. For example, if the State isready, it means that the device is ready to be onboarded by the Apstra ZTP server. If the State isdone, it means that the device has completed the ZTP process and is managed by the Apstra server. The State can be manually set or changed in the ztp.Json file to control the behavior of the device during ZTP. For more information, seeApstra ZTP Configuration File.Reference:

Which two statements are correct regarding a pristine configuration in Juniper Apstra? (Choose two.)
When working with logical devices, you specify where each port group is connected.
In this scenario, which two Juniper Apstra Ul options are available to the operator? {Choose two.)
Explanation:
When working with logical devices, you specify where each port group is connected by selecting the port group layout and the port speed and role (s) for each port group.The Juniper Apstra UI offers two options to the operator for the port group role:unusedandgeneric1.
Unused: This option means that the port group is not configured or used by Apstra.This can be useful for ports that are faulty, reserved, or not part of the data center fabric1.
Generic: This option means that the port group is configured with a generic role that is not specific to any device type or function.This can be useful for ports that are used for testing, troubleshooting, or custom purposes1.Reference:

Exhibit.
Referring to the exhibit, how do you display the IPv6 subnets lot all of the listed VXLANs?
Explanation:
Referring to the exhibit, the image shows a user interface of the Juniper Apstra software application, which is used for network management and configuration. The image shows the Virtual Networks table under the Resources menu, which displays the details of the VLANs and VXLANs in the network. The table has 11 columns, but only 9 are visible in the image. The other two columns are IPv6 Connectivity and IPv6 Subnet, which are hidden by default. To display the IPv6 subnets for all of the listed VXLANs, the user needs to select Columns, then select IPv6 Subnet. This will show the IPv6 Subnet column in the table, which will display the IPv6 addresses assigned to the VXLANs from the IPv6 pools. For more information, seeVirtual Networks (Resources).Reference:

Which three statements describe intent-based analytics? (Choose three.)
Explanation:
Intent-based analytics (IBA) is a feature of Juniper Apstra that allows you to combine intent from the network design with current and historic data from devices to reason about the network at-large1. IBA has the following characteristics:
It is a real-time information processing pipeline. This means that IBA can ingest, process, and analyze large amounts of data from devices in real time, using agents and probes. Agents are software components that collect data from devices and send them to the Apstra server.Probes are user-defined queries that aggregate data across devices and generate advanced data that can be more easily reasoned about1.
It is used to establish network performance baselines. This means that IBA can use the advanced data to measure and monitor the network performance against the expected outcomes and service levels.IBA can also use the historic data to create baselines that represent the normal behavior and state of the network2.
It alerts the network operator when network performance moves away from the baseline. This means that IBA can detect and report any anomalies or deviations from the baseline or the intent in the network.IBA can also provide insights and recommendations for troubleshooting and resolving the issues2.
The following two statements are incorrect in this scenario:
It indicates when device operating versions require updating. This is not true, because IBA does not provide any information or guidance about the device operating versions or updates.IBA is focused on the network performance and compliance, not on the device maintenance or upgrade1.
It collects information from vendor websites. This is not true, because IBA does not collect any information from vendor websites or external sources.IBA only collects information from the devices in the network, using agents and probes1.

Which two statements ate correct about the graph query output shown in the exhibit? (Choose two.)
Explanation:
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:
