Free Practice Questions for Juniper JN0-1103 Exam

The Juniper Connected Security strategy aims to integrate security across the entire network by extending protection to routers, switches, and every point of connection, ensuring that security is enforced holistically - not just at the perimeter.

For a cost-sensitive small data center, the EX4300 and EX4400 switches are suitable leaf node options. They offer sufficient port density and features like Virtual Chassis or EVPN-VXLAN (EX4400) at a lower cost compared to high-end QFX models.

Fault management helps detect and address potential issues before downtime occurs, while measuring network performance, errors, and security metrics enables administrators to make data-driven decisions for maintaining and optimizing the network.

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.

In SD-WAN,path selections are made at the local routing engine level on each SD-WAN router based on policies defined by the centralized controller. This allows for real-time, dynamic traffic steering without requiring per-packet decisions from the controller.

VXLAN and MPLS are commonly used to encapsulate frames and provide Layer 2 reachability across an IP fabric. VXLAN enables L2 overlays over L3 infrastructure, while MPLS can also be used in L2VPN services to extend L2 connectivity across IP/MPLS networks.

rsync and SFTP are commonly used, cost-free tools for creating and scheduling secure backups of configuration files or data. Both support automation via scripts, making them suitable for designing a reliable backup solution without incurring additional costs.

In an EBGP-based IP fabric, each router is in a separate AS, so route reflection is unnecessary - each peer communicates directly. Also, since EBGP peers can form adjacencies using directly connected interfaces, an IGP is not required for underlay routing, simplifying the control plane.

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.
