Juniper JNCIP-DC Exam Description:
Designed for experienced data center networking professionals with advanced knowledge of the Juniper Networks Junos software and data center devices, this written exam verifies the candidate’s understanding of data center technologies, related platform configuration, and troubleshooting skills.

QUESTION 1
You are designing a network for a small data center.
In this scenario, which underlay protocol allows for the simplest implementation?

A. OSPF
B. IBGP
C. EBGP
D. MPLS

Correct Answer: C

QUESTION 2
You are asked to manage the oversubscription ratio of your spine and leaf IP fabric. You determine that you
are at a 3:1 ratio of downstream to upstream traffic and must achieve a 1:1 ratio.
In this scenario, which two actions would you take to achieve this goal? (Choose two.)

A. Increase the number of server-facing ports that each leaf node uses to carry traffic.
B. Reduce the number of server-facing ports that each leaf node uses to carry traffic.
C. Increase the number of spine nodes in your design.
D. Reduce the number of leaf nodes in your design.

Correct Answer: B,C

QUESTION 3
You are designing a Layer 3 fabric underlay using EBGP. You will implement an EVPN-signaled VXLAN overlay on the Layer 3 fabric.
In this scenario, what must you do in the underlay to ensure that the VXLAN overlay will be able to function properly?

A. The underlay should advertise the host-connected interfaces on all leaf devices.
B. Each device in the underlay should advertise its loopback address.
C. The underlay should be configured with a separate VRF for each potential tenant.
D. The underlay should support the PIM protocol.

Correct Answer: B

QUESTION 4
You are configuring VXLAN, and you must ensure that all switches for the multicast groups advertise their existence and learn about other VTEPs.
In this scenario, which protocol will accomplish this task?

A. OSPF
B. BGP
C. EVPN
D. PIM

Correct Answer: C
