Juniper JN0-683 시험요강:

주제소개
주제 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.
주제 2
  • Layer 3 Fabrics: This section measures the knowledge of professionals managing IP-based networks in data centers. It covers IP fabric architecture and routing, ensuring candidates understand how the network is structured for scalability and how traffic is routed efficiently.
주제 3
  • Data Center Deployment and Management: This section assesses the expertise of data center networking professionals like architects and engineers, focusing on key deployment concepts. Topics include Zero-touch provisioning (ZTP), which automates device setup in data centers without manual input.

질문 # 82
Exhibit.

Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.
Referring to the exhibit, which two configuration changes are required to solve the problem? (Choose two.)

정답：A,D

설명：
* Review of the Exhibit:
* The exhibit shows the switch configuration for Leaf-1 and Leaf-2. The configurations include route distinguishers, VRF targets, and service IDs, all of which are crucial for ensuring proper operation in an EVPN-VXLAN environment.
* Service-ID Consistency:
* The service ID must be consistent across all participating leaf devices in the same EVPN instance to ensure that they are part of the same VXLAN overlay network.
* VRF Target Consistency:
* The vrf-target parameter must also be consistent across devices to ensure that VRFs (Virtual Routing and Forwarding instances) are correctly imported and exported between leaf nodes.
Conclusion:
* Option B:Correct-Setting the same service-id on Leaf-2 ensures that it is part of the same VXLAN overlay as Leaf-1.
* Option D:Correct-The vrf-target on Leaf-2 should match Leaf-1 to ensure consistent routing policies and proper route exchange.


질문 # 83
You have a sample configuration for connecting two sites through EVPN-VXLAN by exchanging IP prefix routes.
Referring to the exhibit, which two statements regarding the configuration are true? (Choose two.)

정답：B,D

설명：
The configuration provided in the exhibit shows an EVPN-VXLAN setup where IP prefix routes are exchanged between two sites. The advertise direct-nexthop option and the VNI (Virtual Network Identifier) settings are crucial in this context.
Option A: The advertise direct-nexthop option ensures that the next-hop route is resolved using only the information carried in the EVPN Type 5 route. Type 5 routes are used for IP prefix advertisement in EVPN, which is key to enabling Layer 3 interconnectivity between different VXLAN segments.
VNI Consistency:
Option C: For the same customer across different devices, the VNI must be consistent. This consistency ensures that all devices can correctly map traffic to the appropriate VXLAN segment, maintaining seamless Layer 2 and Layer 3 connectivity.


질문 # 84
Click the Exhibit button. You have implemented an EVPN-VXLAN data center. Device server1 must be able to communicate with device server2.
Referring to the exhibit, which two statements are correct? (Choose two.)

정답：C,D

설명：
When routing is done in the spines (CRB model) a IREB must be configured at the spines.


질문 # 85
In your EVPN-VXAN environment, you want to prevent a multihomed server from receiving multiple copies ofBUM traffic in active/active scenarios. Which EVPN route type would satisfy this requirement?

정답：A

설명：
* Understanding the Scenario:
* In an EVPN-VXLAN environment, when using multi-homing in active/active scenarios, there's a risk that a multihomed server might receive duplicate copies of Broadcast, Unknown unicast, and Multicast (BUM) traffic. This is because multiple VTEPs might forward the same BUM traffic to the server.
* EVPN Route Types:
* Type 4 Route (Ethernet Segment Route):This route type is used to advertise the Ethernet Segment (ES) to which the device is connected. It is specifically used in multi-homing scenarios to signal the ES and its associated Ethernet Tag to all the remote VTEPs. The Type 4 route includes information that helps prevent BUM traffic duplication in active/active multi-homing by using a split-horizon mechanism, which ensures that traffic sent to a multihomed device does not get looped back.
* Explanation:
* The Type 4 route is crucial for ensuring that in a multi-homed setup, particularly in an active
/active configuration, BUM traffic does not result in duplication at the server. The route helps coordinate which VTEP is responsible for forwarding the BUM traffic to the server, thereby preventing duplicate traffic.
Data Center References:
* Type 4 routes are essential for managing multi-homing in EVPN to avoid the issues of BUM traffic duplication, which could otherwise lead to inefficiencies and potential network issues.


질문 # 86
Which two statements are correct about an ERB architecture? (Choose two.)

정답：B,C

설명：
In an edge-routed bridging architecture, Layer 3 gateway functions are implemented on the leaf devices, so inter-VLAN routing occurs at the edge. The VXLAN tunnel endpoints are also located on the leaf devices, which encapsulate and decapsulate traffic as it enters and exits the overlay.
