Juniper JN0-683 認定試験の出題範囲：

トピック出題範囲
トピック 1
  • Data Center Multitenancy and Security: This section tests knowledge of single-tenant and multitenant data center setups. Candidates such as Data Center Professionals are evaluated on ensuring tenant traffic isolation at both Layer 2 and Layer 3 levels in shared infrastructure environments.
トピック 2
  • VXLAN: This part requires knowledge of VXLAN, particularly how the control plane manages communication between devices, while the data plane handles traffic flow. Demonstrate knowledge of how to configure, Monitor, or Troubleshoot VXLAN.
トピック 3
  • Data Center Interconnect: For Data Center Engineers, this part focuses on interconnecting data centers, covering Layer 2 and Layer 3 stretching, stitching fabrics together, and using EVPN-signaled VXLAN for seamless communication between data centers.
トピック 4
  • EVPN-VXLAN Signaling: This section assesses an understanding of Ethernet VPN (EVPN) concepts, including route types, multicast handling, and Multiprotocol BGP (MBGP). It also covers EVPN architectures like CRB and ERB, MAC learning, and symmetric routing.

Juniper Data Center, Professional (JNCIP-DC) 認定 JN0-683 試験問題 (Q66-Q71):

質問 # 66
You are asked for TX and RX traffic statistics for each interface to which an application server is attached. The statistics need to be reported every five seconds. Using the Junos default settings, which telemetry method would accomplish this request?

正解：B

解説：
Native Sensors: Junos provides "Native Sensors" as part of its telemetry capabilities, which can be used to gather interface statistics like TX (transmit) and RX (receive) traffic. With the default configuration, native sensors can be configured to report traffic statistics at a specified interval, such as every five seconds, making this the correct method to fulfill the requirement for periodic traffic reporting.


質問 # 67
Which parameter is used to associate a received route with a local VPN route table?

正解：B

解説：
route-target community: The route-target community is used to associate a received route with a local VPN route table in an EVPN or MPLS VPN environment. It acts as an import and export policy for routes, ensuring that only the relevant routes are imported into a particular VRF (Virtual Routing and Forwarding instance) based on the matching route-target.


質問 # 68
Which three statements are correct about symmetric IRB routing with EVPN Type 2 routes? (Choose three.)

正解：C、D、E

解説：
* Symmetric IRB Routing with EVPN Type 2 Routes:
* Symmetric Routing: In symmetric IRB (Integrated Routing and Bridging), routing occurs in both directions at the ingress and egress leaf nodes using the same routing logic. This is contrasted with asymmetric routing, where different routing logic is used depending on the direction of the traffic.
* Required Components:
* Option A:An L3 IRB interface is necessary for each VLAN that participates in routing, as it handles the Layer 3 processing for the VLAN.
* Option B:MAC-VRF is required for symmetric routing to maintain a mapping of MAC addresses to the appropriate VRF, ensuring correct forwarding within the EVPN.
* Option D:A transit VNI (Virtual Network Identifier) is required for each VRF to encapsulate the Layer 3 traffic as it traverses the network, allowing the IP traffic to be appropriately forwarded.
Conclusion:
* Option A:Correct-Each local VLAN needs an IRB interface for L3 processing.
* Option B:Correct-MAC-VRF is necessary for handling MAC address resolution in symmetric routing.
* Option D:Correct-Transit VNIs are required for routing VRF-specific traffic across the network.
OptionsCandEare incorrect because:
* C:Symmetric routing can work with various VLAN models, including single or multiple VLANs within an EVPN instance.
* E:Symmetric routing is generally more efficient than asymmetric routing as it uses consistent routing logic in both directions.


質問 # 69
You want to convert an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway for VNI 100. You have already configured an IRB interface. In this scenario, which command would you use to accomplish this task?

正解：D

解説：
* Scenario Overview:
* Converting an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway involves transitioning the router's functionality from simply bridging traffic within a VXLAN segment to routing traffic between different segments.
* Key Configuration Requirement:
* IRB (Integrated Routing and Bridging) Interface:An IRB interface allows for both Layer 2 switching and Layer 3 routing. To enable routing for a specific VNI (VXLAN Network Identifier), the IRB interface must be associated with the routing function in the corresponding bridge domain.
* Correct Command:
* C. set bridge-domains VLAN-100 routing-interface irb.100:This command correctly binds the IRB interface to the bridge domain, enabling Layer 3 routing functionality within the VXLAN for VNI 100. This effectively transitions the device from operating solely as a Layer 2 gateway to a Layer 3 gateway.
Data Center References:
* This configuration step is essential when converting a Layer 2 VXLAN gateway to a Layer 3 gateway, enabling the MX Series router to route between VXLAN segments.


質問 # 70
You are using filter-based forwarding with a VXLAN overlay. What are two benefits in this scenario? (Choose two.)

正解：B、D

解説：
Filter-based forwarding allows selective steering of specific traffic flows into different routing instances or service chains, enabling targeted inspection and policy enforcement for only the required flows. By redirecting only matched traffic instead of all traffic, it optimizes resource usage and avoids unnecessary processing, leading to more efficient utilization of network resources.
