質問 # 18
What are three valid resource types supported within Juniper Apstra? (Choose three.)
正解：C、D、E
解説：
In Apstra 5.1, resources are values that must be allocated uniquely and consistently across a fabric so Apstra can render deterministic, conflict-free configurations. These values are managed through resource pools, which provide ranges (or sets) of assignable identifiers that Apstra can automatically allocate to blueprint elements during build and deployment.
Three valid resource pool types in Apstra are ASN pools, VNI pools, and integer pools. ASN pools supply Autonomous System Numbers used in IP fabric underlays (commonly eBGP in three-stage Clos), ensuring each device or role receives the correct AS assignment without manual tracking. VNI pools supply VXLAN Network Identifiers for overlay segmentation in EVPN-VXLAN fabrics. Apstra uses these to create scalable tenant segments where the VNI uniquely identifies the broadcast domain in the overlay, and Junos v24.4 devices (leaf VTEPs) are configured accordingly. Integer pools provide generic numeric values used mainly in Freeform-style designs or in situations where a template needs a consistent allocated integer (for example, a custom ID used by a configlet or another allocation-driven construct).
"Routing zone pools" and "interface pools" are not resource pool types in Apstra. Routing zones (VRFs) are blueprint design objects, and interfaces are physical/logical constructs, but neither is consumed as an allocatable "pool" resource type in the Apstra resource catalog model.
質問 # 19
What does VXLAN use to uniquely label and identify broadcast domains?
正解：C
解説：
In a VXLAN overlay, each Layer 2 broadcast domain (the logical equivalent of a VLAN/bridge domain) is identified by a 24-bit VXLAN Network Identifier (VNI) carried in the VXLAN header. This VNI is what allows the overlay to scale far beyond traditional VLAN space (12-bit VLAN IDs), enabling up to ~16 million distinct segments. In an EVPN-VXLAN data center fabric, Junos v24.4 leaf switches operate as VTEPs and map local bridge domains (often associated with VLANs on server-facing ports) to a VNI. When traffic is sent across the routed underlay, the leaf encapsulates Ethernet frames into VXLAN packets and inserts the VNI so the receiving VTEP can place the frame into the correct broadcast domain on decapsulation.
Apstra 5.1 abstracts this mapping through virtual networks and resource allocation: when you define a VXLAN-based virtual network, Apstra allocates a VNI from the appropriate pool and consistently programs the necessary constructs on all participating leaves. The key point is that VNI is the unique identifier in the VXLAN data plane used to label the broadcast domain across the IP fabric; VLAN IDs may exist locally at the edge for tagging, but the globally significant overlay identifier is the VNI.

質問 # 20
Which type of generic system should you select when adding a new server inside an existing rack type?
正解：C
解説：
In Apstra 5.1, servers that connect to leaf switches are represented as generic systems so Apstra can model links, apply connectivity templates, attach virtual networks, and validate intent. The selection of generic system type depends on whether the endpoint is considered part of the rack's internal topology or an external attachment. When you add a new server inside an existing rack type, that server is treated as a component of the rack topology (that is, it lives "within" the rack alongside leaf switches and any other rack-internal endpoints). Apstra documentation refers to such systems as internal generic systems.
Internal generic systems are not managed like switches (no full device management), but they are first-class topology objects: they occupy ports on leaf switches, can be tagged with roles, and can be associated with link definitions that drive correct interface intent (LAG vs single link, VLAN tagging, and virtual network association). This modeling is essential in EVPN-VXLAN fabrics because correct endpoint attachment on leaf ports determines VLAN/VNI mapping and the resulting Junos v24.4 configuration rendered by Apstra.
External generic systems, by contrast, represent devices outside the rack topology (often used for external routers, firewalls, or other non-rack-contained endpoints). Because the question explicitly places the server inside an existing rack type, the correct choice is Internal generic.

質問 # 21
In Juniper Apstra's role-based access control, what do tenant permissions determine?
正解：C
解説：
In Juniper Apstra's Role-Based Access Control (RBAC), tenant permissions determine which virtual networks a user can administer. This provides fine-grained control over what elements within a multi-tenant environment a user can view or modify. Each tenant is associated with specific virtual networks, and users with tenant permissions can only manage those assigned segments.
質問 # 22
Which Root Cause Identifier is currently supported in Juniper Apstra software?
正解：B
解説：
In Juniper Apstra 5.1, Root Cause Identification (RCI) is implemented with a currently supported model focused on connectivity. Practically, this means RCI is designed to take telemetry and state learned from the fabric (for example, interface operational status, LLDP neighbor information, and routing session status) and correlate those signals to determine the most likely underlying cause of a connectivity-impacting event. Within an EVPN-VXLAN IP fabric, many operational symptoms can appear similar at the service layer (endpoints cannot reach each other, routes disappear, overlays degrade), but RCI narrows the problem by correlating evidence across the underlay and control plane.
The "connectivity" RCI model targets common failure scenarios that directly break device-to-device reachability, such as a broken link, a miscabled link (wrong LLDP neighbors), or an operator-disabled interface. These conditions often cascade into higher-level symptoms, including BGP sessions dropping over affected links. With Junos v24.4-based leaf-spine fabrics, maintaining stable underlay connectivity is foundational for EVPN signaling and VXLAN forwarding; therefore, Apstra's connectivity-focused RCI helps operators rapidly isolate whether the primary fault lies in physical adjacency, cabling/neighbor correctness, or administrative shutdown-reducing mean time to repair by pointing to the most probable root cause rather than only listing alarms.
