Juniper Updated JN0-682 Exam Questions and Answers by harriett

A. If BGP multipath is not configured, traffic may not be load-balanced across multiple paths. B. Without proper load-balancing policies, traffic distribution might not be optimal. D. Insufficient bandwidth between spine and leaf can lead to congestion and affect load balancing.

A VXLAN Network Identifier (VNI) is crucial in VXLAN as it identifies a specific VXLAN segment, allowing for traffic segregation and logical network partitioning within the same physical infrastructure. VNIs also play a role in validating remote VTEPs (VXLAN Tunnel Endpoints) as part of the VXLAN encapsulation and decapsulation process.

For enabling visibility into EVPN-VXLAN network traffic through continuous monitoring:

• You must enable sFlow monitoring on each interface individually (Option C):sFlow is a sampling technology used for monitoring network traffic. In a Juniper environment, sFlow needs to be enabled on individual interfaces to start collecting traffic samples. This allows for granular control over which interfaces are monitored.
• You cannot enable sFlow monitoring on each interface individually (Option A):This statement is incorrect, contradicting the above explanation. sFlow can and should be enabled on specific interfaces as needed.

The option stating that the sFlow agent needs to be manually installed on QFX Series switches (Option D) is inaccurate, as the sFlow feature is typically integrated into the Junos OS running on QFX Series switches. The statement about the sFlow agent being installed by default on QFX Series switches (Option B) is partially true but does not directly address the question of enabling visibility into network traffic.
