Q12. 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.

collapsed

circuit switched

rack-based

pod-based

Q21. An operator is working on a capacity-planning exercise. The operator needs to examine the pre-built time-series information regarding link utilization. In the Juniper Apstra UI, which top-level tab would the operator have to access to find this information?

Active

Staged

Dashboard

Q22. Which statement is correct about the Juniper Apstra Rendered configuration?

It is built at commit time and stored in a MySQL database.

It is stored in a NoSQL database and incrementally updated.

It is dynamically tendered at commit time.

It is rendered from the graph database and stored locally.

Q23. What are three valid resource types supported within Juniper Apstra? (Choose three.)

Integer pools

Routing zone pools

Interface pools

VNI pools

ASN pools

Q24. The 10.100.0.0/16 route is being advertised into your BGP IP fabric. ECMP load balancing has been properly enabled on all devices.
In this scenario, how many routes will the leaf device in AS 65000 receive for the 10.100.0.0/16 prefix?

Q25. Which statement is correct about making changes to a predefined device profile in Juniper Apstra?

The changes you make to a predefined device profile will be discarded and overwritten when upgrading the Apstra server version.

The processor load on the Apstra server will be negatively impacted when changes are made to a predefined device profile.

Changing the predefined device profile will also affect deployed devices that use the same profile.

You must reboot the Apstra server after changes are made to a predefined device profile before they will become active.

Q26. Which two statements are correct about probes? (Choose two.)

Default probes can be cloned, modified, and saved.

Only the variable parameters tor default probes can be edited and saved.

All default probes are enabled for all blueprints.

Default probes are enabled, based on the intent for a blueprint.

Q27. 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.

Q28. You are using Juniper Apstra to create security policies that create ACLs on the fabric devices. What are two valid objects that would be used within Apstra in this scenario? (Choose two.)

Virtual network

Domain name

Routing zone

Application signature

Q29. What does VXLAN use to uniquely label and identify broadcast domains?

VLAN ID

Agent Circuit Identifier (ACI)

Virtual Network Identifier (VNI)

End System Identifier (ESI)

Q30. 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.)

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.

EVPN signaled route Type-3 VXLAN tunnels

EVPN signaled route Type-8 VXLAN tunnels
