Juniper Enterprise Routing and Switching, Professional (JNCIP-ENT) Sample Questions (Q74-Q79):

NEW QUESTION # 74
Which address range is used for source-specific multicast?

A. 233.0.0.0/8
B. 232.0.0.0/8
C. 224.2.0.0/16
D. 239.0.0.0/8

Answer: B

Explanation:
PIM SSM introduces new terms for many of the concepts in PIM sparse mode. PIM SSM can technically be used in the entire 224/4 multicast address range, although PIM SSM operation is guaranteed only in the 232/8 range (232.0.0/24 is reserved). The new SSM terms are appropriate for Internet video applications and are summarized in Table 1.

NEW QUESTION # 75
You are troubleshooting an EVPN-VXLAN IP fabric and observe the loop shown in the exhibit.
Which two steps would you take to further troubleshoot this problem? (Choose two.)

A. Verify that the same ESI is configured on the link from the host and that it matches the source.
B. Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present.
C. Verify that the same ESI is configured on the two links from the source.
D. Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present.

Answer: B,D

Explanation:
Type 2 route, MAC with IP advertisement route-Type 2 routes are per-VLAN routes, so only PEs that are part of a VNI need these routes. EVPN allows an end host's IP and MAC addresses to be advertised within the EVPN Network Layer reachability information (NLRI). This allows for control plane learning of ESI MAC addresses. Because there are many Type 2 routes, a separate route- target auto-derived per VNI helps to confine their propagation. This route type is supported by all EVPN switches and routers.
Type 5 route, IP prefix Route-An IP prefix route provides encoding for inter-subnet forwarding.
In the control plane, EVPN Type 5 routes are used to advertise IP prefixes for inter-subnet connectivity across data centers. To reach a tenant using connectivity provided by the EVPN Type 5 IP prefix route, data packets are sent as Layer 2 Ethernet frames encapsulated in the VXLAN header over the IP network across the data centers.

NEW QUESTION # 76
Referring to the exhibit, which statement is correct?

A. The route is learned from three different neighbors.
B. The route is learned from a multipath BGP session.
C. The route is learned from only one neighbor.
D. The route is learned from a multihop BGP session.

Answer: C
