Practice Free JN0-1103 Design - Associate (JNCIA-Design) Exam Questions Answers With Explanation

When placing access points on the same channel, the recommended signal strength threshold to minimize co-channel interference is ?65 dBm. This ensures adequate coverage while avoiding signal overlap that can degrade wireless performance.

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.

PTX Series routers are purpose-built for the core network, offering ultra-high throughput, scalability, and low-latency forwarding ideal for service provider and large-scale data center cores.

Juniper’s Session Smart Routing includes the Juniper Mist cloud, which provides cloud-managed orchestration and AI-driven insights, and the Session Smart Conductor, which centrally manages routing policies, security, and analytics across the SD-WAN fabric.

A greenfield deployment refers to a new deployment in an environment with no existing infrastructure, offering fewer restrictions and greater design flexibility compared to modifying or integrating into an existing network.

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.

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.

UTM (Unified Threat Management) includes content filtering capabilities, allowing you to block access to specific websites or categories. It is the most appropriate solution for implementing web filtering policies in a network security deployment.

To support SRX chassis cluster design, two special interface types are required:

fab (fabric) interfaces for data plane synchronization and control interfaces for control plane communication between the nodes in the cluster.

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.

A private WAN link offers low latency and inherent security without requiring encryption, making it ideal for transmitting sensitive data while conserving computing resources. It ensures dedicated, reliable connectivity between sites.

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 a 3-stage IP fabric, each leaf node must connect to every spine node to ensure full mesh connectivity at Layer 3 between leafs via the spine layer. This design supports ECMP and optimal traffic distribution across the fabric.

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.
