Juniper JN0-1103 Dumps

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.

For reliable out-of-band management and recovery from misconfigurations, terminal servers should be connected through a separate network, such as a 4G LTE modem or a parallel network of independent routers. This ensures access remains available even if the production network is down.

VXLAN is a network virtualization technology that provides a Layer 2 overlay over a Layer 3 underlay. It enables the extension of Layer 2 segments across a Layer 3 infrastructure, facilitating scalable multi-tenant data center networks.

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.

Encrypted Traffic Insights is a Juniper ATP Cloud feature that detects threats within HTTPS trafficwithout decrypting it. It uses metadata, machine learning, and behavioral analysis to identify anomalies while maintaining privacy.

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.

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.

To support fast roaming and AP redundancy, it’s important to have radio frequency coverage overlap, allowing clients to switch APs seamlessly. Deploying APs on the same channel in a controlled manner (e.g., with fast roaming technologies like 802.11r/k/v) can also aid in minimizing transition latency.

In an ESI-LAG configuration, both VTEPs (leaf switches) advertise reachability to the same Ethernet Segment Identifier, ensuring redundancy and load balancing. To make this work correctly with LACP, thesystem ID must be identical on both leafs so that the downstream device sees them as a single LAG endpoint.

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.

The exhibit shows a leaf-spine architecture with two spine layers and one leaf layer, forming a 3-stage IP Clos topology. It also aligns with a 3-tier architecture (Core, Aggregation/Distribution, Access), commonly used in traditional and modern data center designs to improve scalability and performance.

SD-WAN enhances network security by using encryption for WAN traffic, ensuring data confidentiality over public or hybrid networks. It also supports zero-touch provisioning, which simplifies deployment by automating device configuration without manual intervention.

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.

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.

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.

The REST API on Junos devices supports standard HTTP methods such as GET (to retrieve data) and DELETE (to remove configuration elements). However, it is not enabled by default, and HTTPS is typically required for secure communication.

When designing a WLAN, determining the number and location of access points is essential to ensure adequate coverage, capacity, and performance, while minimizing interference and ensuring seamless connectivity.

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.
