JN0-1103 Exam Dumps - Juniper Design Track Certification Questions and Answers

The exhibit shows a hierarchical structure with Leaf, Spine, and Super Spine layers. This architecture is characteristic of a 7-stage IP fabric, which is used in large-scale data centers to provide high scalability and bandwidth. It extends the 3-stage fabric by adding an additional spine layer (Super Spine) for interconnecting multiple spine layers.

Since only the core switches support EVPN-VXLAN, and the access switches do not, the appropriate design is a Campus Fabric core-distribution model. This design allows EVPN-VXLAN at the core while maintaining compatibility with non-fabric-capable access switches using traditional Layer 2 or Layer 3 connectivity.

A greenfield deployment starts from scratch, with no existing infrastructure, allowing for full design freedom. A brownfield deployment involves working within an existing network environment that typically requires integration or upgrades.

WAN aggregation is represented by the central router that connects multiple branch sites through a Carrier Ethernet service to the enterprise WAN, consolidating traffic.

Private WAN is shown through the use of Carrier Ethernet, which is a private service providing secure, dedicated connectivity between branches and the enterprise WAN.

The SRX5800 is a high-performance hardware firewall designed for large data centers and supports 10 GbE interfaces. The vSRX is a virtual firewall that also supports 10 GbE virtual interfaces, making it suitable for virtualized data center environments with high throughput needs.

SD-WAN routes traffic, including security-sensitive data, across MPLS, VPNs, and Internet circuits using encryption and policy-based routing to ensure secure and efficient transmission, even over public networks.

In a Clos data center fabric using IBGP as the underlay, BGP ADD-PATH must be enabled to allow multiple equal-cost paths to be advertised and installed on the leaf switches. This supports ECMP (Equal-Cost Multi-Path) routing, which is essential for optimal traffic distribution in the fabric.

cSRX and vSRX are the virtualized versions of the Juniper SRX Series firewalls designed for deployment in virtual environments. The cSRX is containerized, while the vSRX is a VM-based firewall, both supporting advanced security services in cloud or virtualized data centers.

Juniper Networks supports WAN Assurance through both cloud-only and hybrid cloud models with Session Smart Routing and Mist AI. This flexibility allows organizations to choose fully cloud-managed operations or a combination of cloud and on-premises control based on their requirements.
