You are deploying a 3-stage Clos IP fabric in your data center.
In this scenario, which statement is correct?
In a 3-stage Clos IP fabric, also known as a spine-leaf architecture, the leaf nodes (servers and top-of-rack switches) connect only to the spine nodes (aggregation or core switches). There are no direct physical connections between leaf nodes themselves. This design ensures that all traffic between leaf nodes passes through the spine layer, facilitating efficient data transfer and easy scalability.
You are implementing an EVPN overlay in your IP fabric data center. The IP fabric was stable before configuring the overlay group and EVPN-related settings. After committing the configuration shown in the exhibit on your spine device, you are no longer exchanging any routes in your underlay fabric.
In this scenario, what will solve this problem?
The problem resides in the BGP family configuration. The EVPN NLRI family declaration should be applied under the overlay BGP group to correctly signal EVPN routes. Without this declaration, the BGP sessions will not properly exchange EVPN routes. Moving the EVPN NLRI family declaration to the overlay group will ensure that EVPN signaling is correctly configured, allowing the routes to be properly exchanged.
Which two Juniper Networks products provide protection against zero-day attacks? (Choose two.)
Juniper ATP Cloud provides advanced threat prevention against zero-day attacks by leveraging machine learning and threat intelligence to detect and mitigate threats. SRX Series devices offer next-generation firewall capabilities, including protection against zero-day attacks, by using advanced threat detection and response functions.
Referring to the exhibit, which statement is correct?
The exhibit shows two layers of switches, which consist of spine switches and top-of-rack (ToR) switches. This represents a collapsed fabric architecture, where normally a larger number of spine and leaf switches would be utilized in a full 3-stage or 5-stage Clos network fabric. The ToR switches connecting directly to both spine switches simplify the architecture. This configuration allows for some of the benefits of a full fabric but in a more compact, collapsed form, making it suitable for smaller-scale deployments.
You are asked to configure your IP fabric with OSPF as the underlay routing protocol.
Which two statements are correct about this implementation? (Choose two.)
In an OSPF implementation for an IP fabric, the host-connected interfaces of the leaf node should be included as passive interfaces to prevent OSPF from sending or receiving OSPF packets on these interfaces while still allowing the network to be advertised. This reduces unnecessary OSPF traffic on interfaces that connect to end devices. The spine-connected interfaces of the leaf node should be included in the OSPF configuration to allow OSPF routing between leaf and spine nodes, which is essential for the underlay network to function.
