質問 # 76
The servers attached to your Juniper Apstra managed data center fabric are running VMware.
You want to get the details about which VMs are attached to which leaf interface.
Referring to the exhibit, which statement is correct?
正解：A
解説：
In Juniper Apstra, to see details about which VMs are attached to which leaf interface, Apstra requires integration with the Virtual Infrastructure Manager (VIM), such as VMware vCenter for ESXi environments. Without defining and integrating a VIM, the VMs tab (as shown in the exhibit) will not display any data, even if servers are connected and running.
質問 # 77
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.

Exhibit.
Referring to the exhibit, how many broadcast domains will an Ethernet frame pass through when traversing the IP fabric from Server A to Server B?
正解：B
解説：
Referring to the exhibit, the image shows a simplified diagram of an IP fabric network connecting two servers, labeled as Server A and Server B. The IP fabric is a network architecture that uses a Clos topology to provide high bandwidth, low latency, and scalability for data center networks. The IP fabric consists of spine and leaf devices that use BGP as the routing protocol and VXLAN as the overlay technology1.
A broadcast domain is a logical portion of a network where any device can directly transmit broadcast frames to other devices at the data link layer (OSI Layer 2). A broadcast frame is a frame that has a destination MAC address of all ones (FF:FF:FF:FF:FF:FF), which means that it is intended for all devices in the same broadcast domain. A broadcast domain is usually bounded by a router, which does not forward broadcast frames to other networks2.
In the exhibit, there are two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The first broadcast domain is the one that contains Server A and the leaf device that it is connected to. The second broadcast domain is the one that contains Server B and the leaf device that it is connected to. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network. Therefore, the statement C is correct in this scenario.
The following three statements are incorrect in this scenario:
A . 1. This is not true, because there are not one, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.
B . 4. This is not true, because there are not four, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The spine devices and the leaf devices that are not connected to the servers are not part of the broadcast domains, because they use IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.
D . 3. This is not true, because there are not three, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.

質問 # 79
What is one indicator in the Apstra UI that implies that changes to a blueprint are ready to be committed?
正解：B
質問 # 80
Which two statements are correct about repairing a Juniper Apstra cabling map before deploying your blueprint? (Choose two.)
正解：A、C
解説：
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.
