After selecting the device in the Dashboard tab, you would select Deploy Mode then Upgrade.

After selecting the device in the Staged tab, you would select Deploy Mode then Drain.

After selecting the device in the Staged tab, you would select Deploy Mode then Upgrade.

After selecting the device in the Active tab, you would select Deploy Mode then Drain.

QUESTION 33
Which statement correctly describes the relationship between Virtual Networks and Routing Zones in Juniper Apstra?

A Virtual Network must be assigned to a Routing Zone, which provides the Layer 3 context for that Virtual Network.

A Routing Zone must be assigned to a single Virtual Network only.

Virtual Networks and Routing Zones are unrelated and configured independently.

Routing Zones are only used for underlay connectivity and have no relationship to Virtual Networks.

QUESTION 34
You are considering the bridged overlay EVPN-VXLAN architecture.
In this scenario, how many VLANs would be enabled in the VLAN-based service type at the MAC-VRF EVPN instance level?

one VLAN

two VLANs

4000 VLANs

four VLANs

QUESTION 35
You have designed your fabric in Juniper Apstra prior to deploying the network devices. Which Apstra element in the Staged tab would be used to assist the team that is installing and cabling the devices?

Connectivity Templates

Virtual Networks table

Managed Devices list

Links table

QUESTION 36
What is the primary reason for creating an Apstra worker node?

to support more than one blueprint

to create a space for storing event logs

to run zero-touch provisioning (ZTP)

to offload off-box agents and IBA

QUESTION 37
What is the purpose of a Juniper Apstra rack?

It stores information on how pods connect to super spines.

It stores information on how leaf nodes connect to generic devices

It stores IP address and ASN pool information.

It stores device port data rates and vendor information.

QUESTION 38
Which two protocols can be used to advertise EVPN routes? (Choose two.)

IS-IS

MP-EBGP

MP-IBGP

OSPF

QUESTION 39
You are using Juniper Apstra to create logical devices and interface maps. You use them in three different rack types. You then modify the logical devices to support the required increased interface speeds and receive an error message when updating the logical devices.

Referring to the exhibit, which action is needed to remove the error?

Remove any templates that reference the logical device.

Remove any interface maps that reference the logical device.

Remove any racks that reference the logical device.

Remove any templates, racks, and interface maps that reference the logical device.

QUESTION 40
Which protocol is used to advertise EVPN routes?

OSPF

BGP

IS-IS

RIP

QUESTION 41
When creating a probe, an operator wants to make it easy to view that probe’s output. In this scenario, which element must be created to accomplish this task?

A dashboard widget

A predefined probe

A processor

A stage

QUESTION 42
You are using tags within Juniper Apstra for searching information in the blueprint about existing elements.
In this scenario, what is another construct that uses tags?

tenants

device context

configlets

services

QUESTION 43
You are creating a template using Juniper Apstr
a. In this scenario, what is a rack-based design compared to a pod-based design?

A rack-based design allows the operator to select a specified number of downlinked servers, whereas a pod-based design only allows the operator to select fixed “pods” of servers.

A rack-based design refers to a three-stage Clos, and a pod design refers to a five-stage Clos.

A rack-based design is suitable for physical servers, whereas a pod-based design is used for Kubernetes deployments.

A rack-based design connects local servers only, whereas a pod-based design can include virtual workloads in a public cloud.

QUESTION 45
In the Juniper Apstra Ul, which three resources are assigned under the Resources menu?
(Choose three.)

VTEP pools

ASN pools

VNI pools

logical device pools

IP address pools

In the Juniper Apstra UI, the Resources menu allows you to create and manage global and local resources that are used for various elements of the network design and configuration. The Resources menu includes the following three types of resources that can be assigned to the network devices and virtual networks:
ASN pools: These are pools of autonomous system numbers (ASNs) that are used for the underlay routing protocol (EBGP) between the leaf and spine devices. You can create ASN pools with either 2-byte or 4-byte ASNs, and assign them to the logical devices in the blueprint. VNI pools: These are pools of virtual network identifiers (VNIs) that are used for the overlay network (VXLAN) between the end hosts. You can create VNI pools with a range of VNIs, and assign them to the virtual networks in the blueprint.
IP address pools: These are pools of IPv4 or IPv6 addresses that are used for various purposes in the network, such as the loopback addresses for the devices, the IP prefixes for the virtual networks, the host IP addresses for the end hosts, and the gateway IP addresses for the IRB interfaces. You can create IP address pools with a range of IP addresses, and assign them to the logical devices and virtual networks in the blueprint.
The following two types of resources are not assigned under the Resources menu:
VTEP pools: These are not resources that can be created or assigned by the user. VTEPs are VXLAN tunnel endpoints that are automatically generated by the Apstra server based on the loopback IP addresses of the devices. VTEPs are used as the source and destination IP addresses for the VXLAN tunnels in the overlay network.
Logical device pools: These are not resources that can be created or assigned by the user.
Logical device pools are groups of logical devices that share the same role, interface map, and resource assignments in the blueprint. Logical device pools are used to simplify the network design and configuration by applying the same settings to multiple devices.

QUESTION 46
Referring to the exhibit, what is the minimum information you must add to create a new routing zone?
