At ValidExamDumps, we consistently monitor updates to the Juniper JN0-682 exam questions by Juniper. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Juniper Data Center, Professional exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Juniper in their Juniper JN0-682 exam. These outdated questions lead to customers failing their Juniper Data Center, Professional exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Juniper JN0-682 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
You are configuring an EVPN overlay network. You want to ensure that leaf devices can respond
to ARP requests from locally connected hosts, when the leaf device knows the MAC of the intended destination.
In this scenario, what should you configure on the leaf devices to accomplish this task?
Configuring Proxy ARP on leaf devices in an EVPN overlay network enables them to respond to ARP requests on behalf of other hosts. When the leaf device knows the MAC of the intended destination, it can reply to ARP requests with its own MAC address, thus facilitating local resolution and avoiding unnecessary ARP traffic across the overlay.
You are asked to scale the available bandwidth within your Clos data center network to support more east-west traffic. In this scenario, what are two ways to accomplish this task? (Choose two.)
In a Clos data center network, scaling the available bandwidth to support more east-west traffic can be effectively achieved by either adding more leaf devices (A) or more spine devices (C). Adding leaf devices increases the total number of endpoints in the network, thereby providing additional paths and bandwidth for east-west traffic. Similarly, adding spine devices increases the interconnectivity within the network, offering more paths for traffic to flow through, which helps in handling higher volumes of east-west traffic. Both approaches work towards enhancing the overall capacity and efficiency of the network. Reference:

You are considering deploying a MAC-VRF type routing instance with a VLAN-bundle service
type. In this scenario, which two statements are correct? (Choose two.)
A MAC-VRF (MAC Virtual Routing and Forwarding) instance with a VLAN-bundle service type is used in EVPN-VXLAN architectures. It can be implemented in a bridged overlay architecture where Ethernet segments are bridged across the EVPN-VXLAN network. This setup supports multiple VLAN IDs per Ethernet VPN Instance (EVI), enabling the segregation and transport of traffic from different VLANs over the same EVPN-VXLAN infrastructure.

You have successfully deployed an IP fabric in your data center. However, your server team complains that they are not seeing an increase in performance as expected. After examining the routing and forwarding tables, you notice that only a single route is listed to each destination in the forwarding table, even though there are multiple routes shown in the routing table.
In this scenario, what should you do to solve the problem?
You must advertise reachability between two firewalls with unique IP subnets that terminate security services through your EVPN-VXLAN environment.
In this scenario, which EVPN route type should you enable to accomplish this task?
