Juniper JN0-683 Exam With Confidence Using Practice Dumps

Zero Touch Provisioning (ZTP):

Juniper Networks' ZTP (Zero Touch Provisioning) process automates the deployment of new devices by allowing them to fetch and execute scripts for configuration and setup as they are powered on and connected to the network.

Supported Scripting Languages:

The Junos OS supports several scripting languages that can be used during the ZTP process:

Shellscripts are often used for general automation tasks.

Pythonis a widely supported language in Junos, offering powerful scripting capabilities for automating network tasks.

SLAX(Service Logic Execution Environment) is a scripting language specific to Junos, designed to automate configuration tasks and simplify network operations.

Conclusion:

Option D:Correct—Junos ZTP supports Shell, Python, and SLAX, making it the correct choice among the provided options.

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.

Telemetry Methods in Junos:

Telemetry is used to collect and report data from network devices. For high-frequency statistics reporting, such as every five seconds, you need a telemetry method that supports this level of granularity and real-time monitoring.

Junos Native Sensors:

Option C:Native Sensors in Junos provide detailed, high-frequency telemetry data, including TX and RX traffic statistics for interfaces. They are designed to offer real-time monitoring with customizable sampling intervals, making them ideal for the five-second reporting requirement.

Conclusion:

Option C:Correct—Native Sensors in Junos are capable of providing the required high-frequency telemetry data every five seconds.
