JN0-649 Exam Dumps Juniper Enterprise Routing and Switching Professional JNCIP-ENT

Here are the details and objectives of the JNCIP-ENT JN0-649 exam:
1. Exam Overview: The JN0-649 exam tests expert knowledge of enterprise network architecture and Juniper Networks routing/switching platforms. Successful candidates have the advanced skills required to design, implement and troubleshoot complex enterprise networks built on MX Series routers, EX and QFX Series switches. This exam qualifies for Juniper Networks Certified Internet Professional Enterprise (JNCIP-ENT) certification. 
2. Exam Topics: 
- Advanced Switching: Architect multicasting, private VLANs, virtual switch chassis, data center interconnects, etc. using QFX/EX platforms. Troubleshoot complex Layer 2 environments.     
- IS-IS, OSPF and BGP: Design and deploy OSPF areas, OSPF v3, BGP communities, etc. Manipulate and optimize routing policy.  Troubleshoot intricate IS-IS, OSPF and BGP network issues.
- MPLS and SDN: Build MPLS-based LSP tunnels, segment routing and EVPN networks. Control networks with Junos Fusion and Junos Space Network Management Platform.   
- Data Center Design: Choose optimal platforms, architectures and protocols for data center environments based on requirements. Consider virtualization, overlay networks, cloud integration, etc.  
- High Availability: Design chassis cluster, virtual chassis, nonstop bridging, inline networking, etc. for maximum redundancy with optimal convergence times.  
- Network Monitoring: Establish proactive monitoring of network operations through syslogs, SNMP, sFlow, etc. React to potential issues using tools like traceoptions, CLI debugger, etc.    
- Automation and Scripting: Develop tools and scripts using PyEZ, Junos OS Evolved Scripting Toolkit and REST APIs to automate operational and configuration tasks.  
3. Exam Format: 105 questions, 150 minutes. Multiple choice (single answer and multiple answers). 
4. Exam Tips: 
- Expertise with MX Series routers, EX and QFX switches required. Significant experience designing, deploying and troubleshooting large-scale enterprise networks. 
- Specialized knowledge of advanced switching for data centers, virtual chassis, Layer 2 environments, etc. Skilled in manipulating and optimizing IS-IS, OSPF, BGP, MPLS, etc.
- Proficient in data center network design. Understands how to combine virtualization, cloud services, overlay/underlay networks, etc. 
- Focus on high availability, network convergence and redundancy throughout the enterprise infrastructure. 
- Develop monitoring, automation tools and scripts using REST APIs, PyEZ, ESScripting Toolkit to streamline network operations. 
- JNCIP-ENT is Juniper's highest enterprise network certification. It demonstrates expert competency with MX, QFX and EX portfolios for highly complex enterprise environments. Considerable work experience is essential for preparation. 
- Questions will assess advanced architecture, design and troubleshooting skills for service provider networks. The exam evaluates real-world expertise beyond product documentation or training courses. 
In summary, the JN0-649 exam tests advanced proficiency with enterprise network architecture and Juniper platforms. JNCIP-ENT certification signifies the ability to design, implement and troubleshoot intricately built networks for maximum redundancy, scalability and reliability. It leads to leadership roles such as principal network architect or infrastructure strategist. For top network engineers, it offers the pinnacle of achievement in Juniper enterprise routing and switching.
