A data center architect is designing a new leaf-spine fabric using Nokia SR Linux. To ensure rapid fault detection and sub-second convergence for the eBGP underlay, which protocol should be implemented to supplement BGP's native keepalive mechanism?
An administrator successfully commits a new configuration on an SR Linux device. Which component is primarily responsible for translating this new configuration from the YANG model format into protocol buffers (protobufs) to update the Immutability Database (IDB)?
A service provider is using SR Linux to offer Layer 3 VPN services. They need to provide routing table isolation for two different customers, Customer A and Customer B, on the same border leaf switch. Which SR Linux feature is designed specifically for this purpose?
During the initial deployment of a data center fabric, a network engineer wants to automate the process where a new SR Linux switch, upon first boot, can discover its management details, download a bootstrap configuration file, and retrieve its full operational image without manual intervention. What is this process called?
True or False: In a standard leaf-spine architecture, leaf switches are directly connected to other leaf switches to optimize east-west traffic flow.
A network operations team needs to configure an SR Linux router to send all log messages with a severity level of 'warning' or higher to a remote syslog server at 192.168.100.50. Which TWO configuration elements are essential to achieve this? (Select TWO).
An engineer is troubleshooting an issue where a newly configured subinterface on an SR Linux leaf switch is not passing traffic. The physical interface is up. The subinterface is configured with VLAN ID 100 and associated with a network instance. Which `show` command would be most effective to verify if the subinterface itself is operationally up and correctly configured?
**Case Study:** A large e-commerce company is building a new data center fabric with Nokia 7220 IXR routers running SR Linux. The design uses a 4-spine, 64-leaf topology with an eBGP-based IP fabric underlay. The primary goal is to ensure maximum path utilization for the heavy east-west traffic generated by their microservices architecture. All inter-switch links are 100Gbps. During testing, the network team observes that traffic flows between two specific virtual machines on different leaf switches consistently use only one of the four available paths through the spine layer, even under heavy load. The BGP routing tables on the source leaf switch correctly show four equal-cost paths to the destination leaf's loopback address. The team has confirmed there are no BGP policy configurations that would alter path selection. What is the most probable cause for this observed traffic imbalance?
When navigating the SR Linux CLI, an administrator is deep within the configuration context, such as `/configure network-instance default interface ethernet-1/1`. What is the most efficient command to return directly to the top-level operational mode root (`/`)?
In an SR Linux system, what is the purpose of configuring a `subinterface` within a `MAC-VRF` network instance?
