JN0-349 Exam Dumps Juniper Enterprise Routing and Switching Specialist JNCIS-ENT

Here are the details and objectives of the JNCIS-ENT JN0-349 exam:
1. Exam Overview: The JN0-349 exam tests intermediate knowledge of Juniper Networks enterprise routing and switching platforms. Successful candidates have the skills required for day-to-day configuration, monitoring and maintenance of Juniper EX and QFX Series switches together with MX Series routers. This exam qualifies for Juniper Networks Certified Specialist Enterprise (JNCIS-ENT) certification. 
2. Exam Topics: 
- Device Management: Configure system parameters, interfaces, SNMP, NTP, syslog, etc. Monitor device status, chassis alarms and network events. Manage software upgrades and configuration files.     
- Layer 2 Switching: Implement VLANs, trunk ports, link aggregation groups, spanning tree, etc.  Troubleshoot Layer 2 loops and optimize switched network environments.  
- Layer 3 Routing: Deploy OSPF, BGP, RIPv2, etc. Summarize routes and manipulate routing policy. Monitor protocol neighbors, routing table and exchange of routing information. Troubleshoot routing adjacencies and path selection issues. 
- MPLS Fundamentals: Explain MPLS concepts and deploy basic MPLS functionality. Build LSP tunnels, apply RPM probes and optimize MPLS network performance.  
- High Availability: Implement graceful Routing Engine switchover, nonstop bridging and inline networking on EX/QFX switches. Deploy chassis cluster and virtual chassis for redundancy.     
- Infrastructure Services: Provide DHCP, DNS, RADIUS, 802.1X, captive portal services, etc. Monitor service operations and troubleshoot issues.  
3. Exam Format: 65 questions, 105 minutes. Multiple choice (single answer and multiple answers). 
4. Exam Tips:  
- Strong experience with Juniper EX, QFX Series switches and MX routers required. Proficient knowledge of enterprise network architecture and protocols.   
- Expertise to configure and manage system parameters, interfaces, SNMP, syslog, software upgrades, etc. Monitor device status and events.
- Proficient with Layer 2 switching concepts such as VLANs, trunks, STP, link aggregation, etc. Troubleshoot Layer 2 issues. 
- Skilled in deploying and optimizing OSPF, BGP, MPLS, etc. in enterprise networks. Monitor routing neighbors, routing tables, MPLS LSPs, etc. Resolve routing problems. 
- Knowledgeable in implementing high availability through chassis cluster, virtual chassis, GR, and nonstop bridging on EX/QFX platforms. 
- Familiar with basic infrastructure services like DHCP, DNS, RADIUS, captive portal, etc. Configure, monitor and troubleshoot these services. 
- Questions will assess knowledge and skills for day-to-day operation, monitoring and maintenance of Juniper enterprise routing/switching platforms in medium-complexity environments. Courses, documentation and hands-on experience will aid preparation.   
 - JNCIS-ENT demonstrates competence with Juniper technologies commonly used in enterprise networks. It leads to careers such as network engineer, consultant or support professional.
In summary, the JN0-349 exam evaluates ability to configure and sustain Juniper enterprise routing and switching gear. JNCIS-ENT certification signifies skills to operate the MX, EX and QFX portfolios for everyday networking needs. It validates knowledge of enterprise architecture, device management, Layer 2/3 protocols, MPLS, high availability and infrastructure services. With experience, it demonstrates readiness to advance in Juniper enterprise platform engineering.
