Juniper Data Center, Specialist (JNCIS-DC) 認定 JN0-481 試験問題 (Q66-Q71):

質問 # 66
You created a virtual network and allocated it to the incorrect routing zone.
In this scenario, what are two ways to assign the virtual network property? (Choose two.)

正解：B、D

解説：
Delete the virtual network and then re-create it by assigning the correct routing zone - This is a valid method, especially if editing is restricted or not allowed after initial creation.
Edit the virtual network and replace the incorrect routing zone with the correct routing zone - If the UI allows, this is the more direct approach to fix the assignment without deleting the virtual network.


質問 # 67
What does clicking the indicated icon shown in the exhibit accomplish?

正解：C

解説：
In Apstra 5.1, the Staged > Physical > Links workspace is where you build and validate the cabling (link) intent for the fabric before committing changes. During deployment and day-0/1 build, Apstra can leverage LLDP neighbor discovery from the connected devices to accelerate and validate the cabling map. The indicated toolbar icon in the Links view is used to fetch discovered LLDP data from the devices so Apstra can compare the discovered neighbor relationships with the intended topology and, depending on workflow, help populate or validate link endpoints.
This is particularly important in leaf-spine IP fabrics because correct physical connectivity underpins the entire underlay-interface states, point-to-point addressing, and BGP sessions. In an EVPN-VXLAN design running Junos v24.4, broken or mis-cabled links quickly manifest as missing underlay adjacencies and failed EVPN control-plane signaling. Pulling LLDP discovery into Apstra helps you identify mismatches early (wrong neighbor, wrong port, missing neighbor) and reduces manual cabling errors.
This action is not merely a UI refresh, it does not wipe the cable map, and it does not modify link speeds. Its operational purpose is to import discovered LLDP neighbor information into the blueprint's physical link view so Apstra can assist with accurate topology validation and deployment readiness.


質問 # 68
In Juniper Apstra terminology, to which network operating system concept does a routing zone refer?

正解：D

解説：
In Apstra 5.1, a routing zone is the primary construct used to represent an L3 domain for multitenant isolation. In traditional network operating system terms, that maps to a VRF (Virtual Routing and Forwarding instance). Each routing zone is placed "in its own VRF," which provides independent routing tables and isolates IP traffic so that different tenants can reuse overlapping IP subnets without conflict. This is central to modern EVPN-VXLAN data center design, where tenants typically require clean separation of routing and policy boundaries.
Within a routing zone, you can create one or more virtual networks (often mapped to VXLAN segments) that provide L2 extension across racks while still being contained by the tenant's VRF. If L3 gateway services are enabled for those virtual networks, their gateway interfaces (for example, IRB interfaces on Junos v24.4 leaf switches) are associated with the routing zone's VRF so that inter-subnet routing occurs within the tenant boundary.
This terminology distinction is important: an IRB is an interface construct used to provide L3 gateway functionality for a VLAN/VXLAN segment; a VLAN is a Layer 2 segmentation mechanism; and an access list is a policy enforcement tool. A routing zone, however, defines the tenant's L3 routing context, which is precisely what a VRF provides on Junos.

質問 # 69
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.)

正解：A、B

解説：
In Apstra 5.1, Security Policies express traffic-permit/deny intent between defined fabric endpoints, and Apstra compiles that intent into ACL enforcement on the appropriate switches (for example, on gateway interfaces for east-west segmentation and on border leaf interfaces for north-south controls). The objects you use to define that policy intent must correspond to fabric connectivity constructs that Apstra understands as endpoints in the blueprint's logical model.
Two such valid objects are Virtual Networks and Routing Zones. A virtual network represents a tenant segment (typically mapped into EVPN-VXLAN constructs such as VNI and associated IRB gateway when L3 is enabled). Policies between virtual networks are a common way to implement micro-segmentation or tier-based segmentation (web/app/db) within the same tenant boundary. A routing zone represents the L3 tenancy boundary (mapped to a VRF) and can be used to group and control connectivity at the tenant level, especially where policy needs to be expressed for aggregated tenant domains or for controls involving external connectivity.
"Domain name" and "application signature" are not endpoint objects for Apstra Security Policies in this context. They may exist in other security ecosystems, but Apstra's security intent model for ACL generation is based on topology and blueprint objects (routing zones, virtual networks, and endpoint definitions), which can then be rendered into Junos v24.4 firewall filter-style enforcement on the fabric devices.

質問 # 70
Referring to the exhibit, what happens when an operator clicks the Accept Changes button on the right side of the screen in Juniper Apstra?

正解：B

解説：
In Juniper Apstra, the Accept Changes button is used when the running configuration on a device has been manually modified outside of Apstra's intent-based automation. Clicking Accept Changes reconciles these differences by updating Apstra's "golden config" to include the CLI- entered changes, ensuring that Apstra's intended state matches the actual device configuration.
This way, Apstra will stop flagging the deviation as a mismatch.
