JN0-664 Exam Dumps Service Provider Routing and Switching Professional JNCIP-SP

Here are the details and objectives of the JNCIP-SP JN0-664 exam:
1. Exam Overview: The JN0-664 exam tests advanced knowledge of Juniper Networks switch and router platforms. Successful candidates have the skills required for planning, implementing and operating Junos OS environments. This exam qualifies for Juniper Networks Certified Internet Professional - Service Provider (JNCIP-SP) certification. 
2. Exam Topics: 
- Junos Platform Architecture:  Compare MX, PTX and QFX architecture, redundancy, power and cooling options. Determine optimal platform based on requirements.
- Advanced Junos Configuration: Implement dynamic configuration templates. Use groups and apply factory-default groups. Configure metrics and metrics policies. Apply scheduling options. 
- VPN Implementation: Configure IPsec, GRE, L2TP and MPLS L3VPNs. Deploy VTI, SA, Hub/Spoke topologies. Implement BGP, OSPF, MP-iBGP and LDP in VPN environments.
- Advanced Routing: Design routing policy, policy-statements and policy-options. Implement routing instances. Leverage routing table aggregation and summarization. Deploy BGP, IS-IS and OSPF in SP environments. 
- Advanced MPLS: Build MPLS domains with LDP and RSVP-TE. Apply MPLS to SP networks and Layer 2 VPNs. Implement LDP, RSVP-TE tunneling, FRR, shortcuts and entropy label. 
- Class of Service: Apply forward and local preference, multi-protocol BGP and IS-IS extensions for TE and link bandwidth. Provision COS for MPLS LSPs, GRE tunnels and scheduler algorithms. 
- Advanced Troubleshooting: Troubleshoot routing engine and forwarding anomalies. Check MPLS LSP connectivity and FIB inconsistencies. Debug BGP, IS-IS, OSPF, LDP and RSVP-TE issues. Analyze core dumps and packet captures. Resolve complex problems.
3. Exam Format: 105 questions, 150 minutes.  Multiple choice (single answer and multiple answers). 
4. Exam Tips: 
- Significant knowledge of Junos platform architecture required for capacity planning and design. Hands-on experience with QFX, MX, PTX, etc.  
- Expertise to configure advanced Junos networking features like scheduling, groups, templates, etc. Requires in-depth understanding of Junos OS. 
- Proficient with implementing and operating MPLS, IPsec VPNs, BGP, IS-IS, OSPF,  CoS, etc. in SP environments. Knowledge of related protocols and standards is needed.
- Advance troubleshooting skills for resolving complex issues. Check statistics, logs, debugs, and packet captures to diagnose problems with routing engines, FIB, MPLS LSPs, BGP, IS-IS, OSPF, etc. 
- While documentation and courses help with preparation, questions require thinking through challenging SP scenarios. Significant hands-on experience with routing platforms is essential.  
- JNCIP-SP signifies a professional level of competence in planning, implementing and maintaining Juniper backbone networks. It leads to careers as a backbone engineer, technical consultant or professional services manager.
In summary, the JN0-664 exam evaluates advanced knowledge and skills for deploying and supporting Junos platforms in SP environments.  JNCIP-SP certification validates competence with routing protocols, MPLS, IPsec VPNs, class of service, troubleshooting, and related technologies at an expert level. With diligent preparation, it signifies the ability to advance infrastructure architecture and operations for service provider networks. The credential aims professionals seeking leadership roles in SP engineering.
