Free and Premium Juniper JN0-1103 Dumps Questions Answers

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.

EVPN-VXLAN is an overlay solution that extends Layer 2 network segments across a Layer 3 WAN. It enables seamless connectivity between remote sites or data centers while maintaining Layer 2 adjacency, making it ideal for distributed environments.

BGP multipath with multiple-as is required in an EBGP underlay to enable ECMP across multiple autonomous system paths. In an IBGP underlay, Route Reflectors help scale the control plane by reducing the need for a full mesh of BGP sessions among all fabric nodes.

For a 120-meter (400-foot) connection between switches, multimode fiber is the most reliable and cost-effective option. It supports higher bandwidth and longer distances than UTP (which is limited to 100 meters) and is more stable and secure than a wireless solution.

Secure Vector Routing (SVR) is specifically designed for SD-WAN environments with limited bandwidth, as it offers encrypted and policy-based routing with minimal overhead compared to protocols like IPsec or GRE. This makes it ideal for bandwidth-constrained branch sites.

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.

Mist Edge enables seamless mobility and roaming for real-time applications like VoIP by extending Mist’s cloud services to the on-premises edge. It reduces latency and enables fast, reliable handoffs between APs and buildings - resolving issues like dropped VoIP calls during roaming.

Reducing the oversubscription ratio means provisioning more uplink bandwidth relative to access bandwidth, which improves congestion handling and performance but also increases network cost due to the need for additional or higher-capacity links and equipment.

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.

Modularity in network design allows for easier scalability, troubleshooting, and future upgrades by segmenting the network into functional blocks. This approach simplifies management and enhances the network's ability to adapt to changing requirements.

Capacity planning requires a clear view of the current application behavior to assess real-time demands and predicting future traffic projections to ensure the network can scale efficiently and handle increased load over time.

The oversubscription ratio in an IP fabric is influenced by the number of spine nodes relative to the number of leaf nodes and their uplinks.

Removing spine nodes reduces available uplink bandwidth, increasing oversubscription.

Adding spine nodes increases available bandwidth between leafs and spines, decreasing the oversubscription ratio.

Planned outages (for maintenance or upgrades) and WAN failures (due to carrier or link issues) both directly impact network uptime by causing service disruptions, either scheduled or unexpected.

A Secure Web Gateway (SWG) provides proxy services to inspect and filter web traffic and includes firewall capabilities to enforce security policies, block threats, and control access to internet resources.

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.

To establish an accurate network baseline, it's essential to understand the expected application behavior and gather a comprehensive history of performance metrics over time. This helps identify deviations and troubleshoot issues effectively.

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.

These elements directly impact port density and scaling requirements in a campus switching design. Understanding the number of unmanned devices, fixed user workstations with IP phones, and standalone VoIP phones is critical for calculating the total number of access ports needed and ensuring the infrastructure can support current and future capacity demands.

IPsec with NAT Traversal (NAT-T) encapsulates IPsec packets within UDP headers, adding additional overhead compared to standard IPsec. This results in higher packet overhead, which can affect performance and MTU handling more than other VPN protocols.
