Juniper JN0-683 Exam Syllabus Topics:

Topic	Details
Topic 1	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.
Topic 2	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.
Topic 3	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.

Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q95-Q100):

NEW QUESTION # 95
Referring to the exhibit, which statement is true?

A. An ERB architecture is being used.
B. An OTT architecture is being used.
C. A CRB architecture is being used.
D. A PBB-EVPN architecture is being used.

Answer: A

Explanation:
The configuration provided in the exhibit indicates an EVPN-VXLAN setup with routing instances, VLANs, and associated VXLANs. Specifically, there are routing instances with IRB interfaces (Integrated Routing and Bridging) and associated VLANs, as well as VNI assignments, which are key elements in an Enhanced Routed Bridging (ERB) architecture. This architecture supports both Layer 2 and Layer 3 connectivity with VXLAN for bridging and routing.

NEW QUESTION # 96

The 192.168.0.0/24 route is being advertised into your IP fabric by the leaf device in AS 65512.
In this scenario, which two statements are correct? (Choose two.)

A. By default, each spine device will advertise this route to all other peer leaf devices.
B. By default, each spine device will not advertise this route to all other peer leaf devices.
C. By default, both spine devices will accept and install the route learned from the leaf device.
D. By default, both spine devices will reject the route learned from the leaf device.

Answer: B,C

Explanation:
The spines learn 192.168.0.0/24 from the leaf over an eBGP session, and Junos will accept and install received BGP routes by default. However, Junos does not advertise routes to BGP peers unless an export policy explicitly permits them, so the spines will not advertise that route onward to the other leaf peers by default.

NEW QUESTION # 97
You are preparing an sFlow monitoring system configuration.
In this scenario, what Information will be included in the datagram sent to the sFlow collector? (Choose two.)

A. the CRC from the sampled packet
B. the sending device's serial number
C. the source and destination VLAN for sampled packets
D. the interlace through which the packets entered the agent

Answer: C,D

Explanation:
* Understanding sFlow Monitoring:
* sFlow is a packet sampling technology used to monitor traffic in a network. It sends sampled packet data and interface counters to an sFlow collector, which analyzes the traffic patterns.
* Information Included in sFlow Datagram:
* Option A:The datagram sent to the sFlow collector includes information about the interface through which the packets entered the agent (the switch or router). This is crucial for understanding where in the network the traffic was captured.
* Option D:sFlow datagrams also include the source and destination VLAN for the sampled packets. This allows for detailed analysis of the traffic flow within different VLANs.
Conclusion:
* Option A:Correct-The ingress interface is included in the sFlow datagram.
* Option D:Correct-The source and destination VLANs are also included, providing context for the sampled traffic.

NEW QUESTION # 98
Click the Exhibit button.

The 192.168.0.0/24 route is being advertised into your IP fabric by the leaf devices in AS 65511 and AS 65512. Both spine devices receive the routes from each of the leaf devices.
In this scenario, which two statements are correct? (Choose two.)

A. By default, each spine device will only accept the first received next hop for this route from the leaf devices, while the other next hop will be rejected.
B. By default, each spine device will advertise only the active route entry to the other leaf devices.
C. By default, each spine device will advertise both route entries for this route to other leaf devices.
D. By default, each spine device will accept both next hops for the route received from the leaf devices, but only one next hop will become the active route.

Answer: A,B

Explanation:
The two advertisements for the same prefix arrive with different next hops, but the default BGP behavior in Junos is to select a single best path for installation; additional paths are not kept as usable next hops unless multipath is explicitly enabled, so the nonselected next hop is not used.
Also, Junos will not advertise routes to BGP peers unless an export policy explicitly permits them; when it does export, it advertises only the selected active route, not multiple equal candidates.

NEW QUESTION # 99
You are asked to interconnect two of your company's data centers across an IP backbone. Both data centers require Layer 2 and Layer 3 connectivity. In this scenario, which three actions would accomplish this task?
(Choose three.)

A. Ensure border leaf nodes in each data center can exchange EVPN routes.
B. Advertise Type 2 EVPN routes across the DCI.
C. Advertise Type 5 EVPN routes across the DCI.
D. Ensure there is a full mesh of VTEPs between all leaf nodes within data centers.
E. Ensure there is a full mesh of VTEPs between all spine nodes within both data centers.

Answer: A,B,C

Explanation:
* Layer 2 and Layer 3 Connectivity Requirements:
* To interconnect two data centers across an IP backbone with both Layer 2 (L2) and Layer 3 (L3) connectivity, EVPN-VXLAN (Ethernet VPN with Virtual Extensible LAN) is the ideal solution.
EVPN supports L2 VPNs while also enabling L3 connectivity across multiple locations.
* Necessary EVPN Route Types:
* Type 2 EVPN Routes:These routes are used to advertise MAC addresses for Layer 2 connectivity. They are essential for enabling seamless L2 communication across data centers.
* Type 5 EVPN Routes:These routes are necessary for advertising IP prefixes for Layer 3 connectivity between data centers. They enable the exchange of L3 information across the IP backbone, ensuring routed traffic can reach its destination.
* Border Leaf Nodes:
* Border Leaf Nodes:Ensuring that the border leaf nodes (the entry and exit points for traffic between data centers) can exchange EVPN routes is critical for the correct dissemination of both L2 and L3 information across the data centers.
Conclusion:
* Option A:Correct-Type 2 EVPN routes are required for Layer 2 MAC address learning and communication across the DCI (Data Center Interconnect).
* Option B:Correct-Border leaf nodes need to exchange EVPN routes to maintain connectivity between data centers.
* Option D:Correct-Type 5 EVPN routes are essential for Layer 3 connectivity across the DCI.
OptionsCandEare incorrect because they refer to establishing full mesh VTEPs (VXLAN Tunnel Endpoints) across all spine or leaf nodes, which is unnecessary for the scenario provided. The focus should be on border leaf nodes and appropriate route advertisements for L2 and L3 connectivity.
