Q16. In Juniper Apstra. which three modes are available for devices? (Choose three.)

Deploy

Active

Stopped

Drain

Ready

Juniper Apstra supports three deploy modes for devices: Deploy, Drain, and Ready. These modes determine the configuration and state of the devices in the data center fabric.
Deploy: This mode applies the full Apstra-rendered configuration to the device, according to the Apstra Reference Design. The device state becomes IS-ACTIVE and the device is ready to carry traffic in the fabric.
Drain: This mode adds a “drain” configuration to the device, which prevents any new traffic from entering the device. The device state becomes IS-READY and the device is prepared for maintenance or decommissioning.
Ready: This mode removes the Apstra-rendered configuration from the device, leaving only the basic configuration such as device hostname, interface descriptions, and port speed/breakout.
The device state becomes IS-READY and the device is not part of the fabric.

Q17. Which three statements describe intent-based analytics? (Choose three.)

It indicates when device operating versions require updating.

It is a real-time information processing pipeline.

It is used to establish network performance baselines.

It alerts the network operator when network performance moves away from the baseline.

It collects information from vendor websites.

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- large.
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 about.
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 network.
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 issues.

Q18. Which two actions are required during Juniper Apstra’s deploy phase? (Choose two.)

Assign device profiles to the blueprint.

Assign user roles to the blueprint.

Assign interlace maps to the blueprint.

Assign resources to the blueprint.

The deploy phase is the final step in the Juniper Apstra data center fabric design and deployment process. In this phase, you apply the Apstra-rendered configuration to the devices and verify the intent of the blueprint. Based on the web search results, we can infer the following actions are required during the deploy phase:
Assign device profiles to the blueprint. This action associates a specific vendor model to each logical device in the blueprint. 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. Assign resources to the blueprint. This action allocates the physical devices, IP addresses, VLANs, and ASNs to the logical devices, networks, and routing zones in the blueprint. Resources can be assigned manually or automatically by the Apstra system. Assigning resources ensures that the blueprint has all the necessary elements to generate the configuration and deploy the fabric5 . Assign user roles to the blueprint. This action is not required during the deploy phase. User roles are defined at the system level, not at the blueprint level. User roles determine the permissions and access levels of different users in the Apstra system. User roles can be system-defined or custom-defined .
Assign interface maps to the blueprint. This action is not required during the deploy phase.
Interface maps are defined at the design phase, not at the deploy phase. Interface maps are objects that map the logical interfaces of a logical device to the physical interfaces of a device profile. Interface maps enable the Apstra system to generate the correct interface configuration for each device in the fabric.

Q19. 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.)

Disable IPv4 connectivity when creating the virtual network within the same Routing Zone.

Enable Security Policy for virtual networks in the same Routing Zone.

Disable Route Target exports when creating the Routing Zones.

Use Connectivity Templates to block access within the same Routing Zone.

Put each network in different Routing Zones.

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 devices.
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 port.
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 them.

Q20. Multilenancy for applications is achieved by creating virtual networks (VNs) within which construct?

routing zone

routing table

connectivity template

security policy

Q21. Within Managed Devices in the Juniper Apstra Ul, you notice that several devices have the OOS- Quarantined status. The devices cannot be added to any blueprint. Which action would solve this problem?

Acknowledge the device.

Fix the hardware issues with the quarantined devices.

Install the agent, even though connectivity is established.

Upload a new pristine configuration.

When an agent installation is successful, devices are placed into the Out of Service Quarantined (OOS-QUARANTINED) state using the Juniper Apstra UI. This state means that the device is not yet managed by Apstra and has not been assigned to any blueprint. The device configuration at this point is called Pristine Config. To make the device ready for use in a blueprint, you need to acknowledge the device, which is a manual action that confirms the device identity and ownership. Acknowledging the device changes its status to Out of Service Ready (OOS- READY).

Q22. You are creating a new template that will connect two rack based templates together. Which rack type should be used to accomplish this rask?

collapsed

rack based

isolated

pod based

Q23. In the case of IP Clos data center five-stage fabric design, what are two rotes of the super spines? (Choose two.)

Super spines are used to interconnect two different data center pods.

Super spines connect to all spine devices within the five-stage architecture.

Super spines are used to connect leaf nodes within a data center pod.

Super spines are always connected to an external data center gateway.

In the case of IP Clos data center five-stage fabric design, the super spines are the devices that provide the highest level of aggregation in the network. They have two main roles:
Super spines are used to interconnect two different data center pods. A pod is a cluster of leaf and spine devices that form a 3-stage Clos topology. A 5-stage Clos topology consists of multiple pods that are connected by the super spines. This allows for scaling the network to support more devices and bandwidth.
Super spines connect to all spine devices within the five-stage architecture. The spine devices are the devices that provide the second level of aggregation in the network. They connect to the leaf devices, which are the devices that provide access to the end hosts. The super spines connect to all the spine devices in the network, regardless of which pod they belong to. This provides any-to-any connectivity between the pods and enables optimal routing and load balancing.

Q24. Which two statements ate correct about the information shown in the exhibit? (Choose two.)

The system is fully managed by Juniper Apstra.

The device shown is a generic system.

Four physical interfaces exist in a LAG facing the leaf pair.

The physical ports are not part of the LAG.

A generic system is a device that is not managed by Juniper Apstra and does not have a specific role or type assigned to it. A generic system can be used to represent a server, a firewall, a load balancer, or any other device that is not part of the fabric. In the exhibit, the device shown is a generic system, as indicated by its role, system type, and management level. Therefore, the correct answer is B. The device shown is a generic system. A LAG is a link aggregation group that bundles multiple physical interfaces into a single logical interface. A LAG can provide increased bandwidth, redundancy, and load balancing for the network traffic. In the exhibit, the device shown has four physical interfaces that are part of a LAG, as indicated by their description and li_type. The LAG is facing the leaf pair, which are the two switches that connect to the device.

Q25. Which two statements are correct about repairing a Juniper Apstra cabling map before deploying your blueprint? (Choose two.)

You must manually change the cabling map to update spine-to-leaf fabric links.

Apstra can use LLDP data from the spine-to-lea! fabric devices to update the connections in the cabling map.

Apstra can use LLDP data from the leaf devices to update the leaf-to-generic connections in the cabling map.

You must manually change the cabling map to update leaf-to-generic links.

The cabling map is a graphical representation of the physical connections between the devices in the data center fabric. It shows the status of the cables, interfaces, and BGP sessions for each device. You can use the cabling map to verify and repair the cabling before deploying your blueprint. Based on the web search results, we can infer the following statements:
Apstra can use LLDP data from the spine-to-leaf fabric devices to update the connections in the cabling map. This is true because Apstra can collect LLDP data from the devices using the Generic Graph Collector processor and use it to update the cabling map automatically.
LLDP is a protocol that allows devices to exchange information about their identity, capabilities, and neighbors. Apstra can use LLDP data from the leaf devices to update the leaf-to-generic connections in the cabling map. This is true because Apstra can also collect LLDP data from the leaf devices and use it to update the connections to the generic devices, such as routers, firewalls, or servers. Generic devices are devices that are not managed by Apstra but are part of the data center fabric.
You must manually change the cabling map to update spine-to-leaf fabric links. This is false because Apstra can use LLDP data to update the spine-to-leaf fabric links automatically, as explained above. However, you can also manually change the cabling map to override the Apstra-generated cabling, if needed.
You must manually change the cabling map to update leaf-to-generic links. This is false because Apstra can use LLDP data to update the leaf-to-generic links automatically, as explained above.
However, you can also manually change the cabling map to override the Apstra-generated cabling, if needed.

Q26. You connect two single-homed servers using Juniper Apstra as shown in the exhibit. You are using the ERB design blueprint with two virtual networks in a common routing zone. In this scenario, which two types of VXLAN tunnels will be automatically created by the EVPN control plane? (Choose two.)

EVPN signaled route Type-6 VXLAN tunnels

EVPN signaled route Type-3 VXLAN tunnels

EVPN signaled route Type-8 VXLAN tunnels

EVPN signaled route Type-2 VXLAN tunnels

EVPN route Type-3 is used to advertise the IP address of the VTEP and the VNIs that it supports.
This allows the VTEPs to discover each other and form VXLAN tunnels for the VNIs that they have in common. EVPN route Type-2 is used to advertise the MAC and IP addresses of the hosts connected to the VTEPs. This allows the VTEPs to learn the MAC-to-IP bindings and the MAC-to- VTEP mappings for the hosts in the same VNI. Therefore, these two types of VXLAN tunnels will be automatically created by the EVPN control plane when using Juniper Apstra with the ERB design blueprint and two virtual networks in a common routing zone.

Q27. You connect two single-homed servers using Juniper Apstra as shown in the exhibit. You are using the ERB design blueprint with two virtual networks in a common routing zone. In this scenario, which two types of VXLAN tunnels will be automatically created by the EVPN control plane? (Choose two.)

EVPN signaled route Type-8 VXLAN tunnels

EVPN signaled route Type-3 VXLAN tunnels

EVPN signaled route Type-6 VXLAN tunnels

EVPN signaled route Type-2 VXLAN tunnels

Q28. What does EVPN use lo identity which remote leaf device advertised the EVPN route?

a route distinguisher value

a community tag

a route target value

a VRF target value

EVPN uses a route distinguisher (RD) value to identify which remote leaf device advertised the EVPN route. An RD is a 64-bit value that is prepended to the EVPN NLRI to create a unique VPNv4 or VPNv6 prefix. The RD value is usually derived from the IP address of the PE that originates the EVPN route. By comparing the RD values of different EVPN routes, a PE can determine which remote PE advertised the route and which VRF the route belongs to.

Q29. Referring to the exhibit, how many rack types are used in the staged blueprint?

six

three

seven

two

Referring to the exhibit, the image shows the Racks table under the Staged menu in the Juniper Apstra UI. The Racks table displays the details of the racks that are used in the blueprint, such as the name, rack type, and date. The rack type is a resource that defines the type and number of leaf devices, access switches, and/or generic systems that are used in rack builds. The image shows seven racks in the table, but only two rack types: BorderLeaf and ServerRack.

Q30. 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?

templates

device profiles

agent profiles

interface map

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.

Q31. You are building an IP fabric and have decided to use Junos devices to create an EBGP underlay. You must ensure that traffic is load balanced throughout your fabric.
You must also ensure that regardless of the path used through the fabric that all traffic is handled consistently and load balanced predictably.
According to Juniper Networks, what are three best practices that you should employ to help you achieve the desired behavior? (Choose three.)

Each leaf device must use the same link speed for all uplinks to the spine devices.

All spine devices should be the same model including linecards and port density.

Each leaf device should be a different model including linecards and port density.

All leaf devices should be the same model including linecards and port density.

Leaf devices should use a variety of link speeds for each uplink to the spine devices.

Q32. Using the Juniper Apstra multitenancy capabilities, which approach will allow a tenant to interconnect two different routing zones?

Interconnection is the default behavior.

Use interconnection through the fabric spine nodes.

Interconnection cannot be enabled.

Use interconnection through an external gateway.

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. For virtual networks with Layer 3 SVI, the SVI is associated with a Virtual Routing and Forwarding (VRF) instance for each routing zone isolating the virtual network SVI from other virtual network SVIs in other routing zones. If you’re using multiple routing zones, external system connections must be from leaf switches in the fabric. Routing between routing zones must be accomplished with external systems.
