Data Center, Professional (JNCIP-DC) JN0-681 Free Dumps

1. Which protocol is used between VCF member devices to create a loop-free topology?

2. You are deploying a VXLAN using EVPN signaling overlay network. PE1 and PE2 are multihomed to the connected CE device.

You notice that the traffic is not load-balancing as expected.

Referring to the exhibit, which two actions will solve this problem? (Choose two.)

3. Referring to the exhibit, R1 and R2 are QFX5100s and are acting as VXLAN Layer 2 Gateways for VLAN 100 using PIM-SM signaling.

What will cause R2 to send a (*.G) PIM Join towards the RP?

4. Your server administrator asks you to preserve the inner VLAN tags of the frames coming from a Layer 2 VXLAN Gateway of the EVPN-enabled segment.

Which two parameters must you add to the configuration to allow the VLAN tag to be passed? (Choose two.)

5. You are implementing a Virtual Chassis using QFX5100s and EX4300s in your data center.

In this scenario, which three hardware capabilities are affected? (Choose three.)

6. The exhibit shows an output from a QFX5100 Series switch serving as an MC-LAG peer.

Which two statements are true in this scenario? (Choose two.)

7. You have built a mixed-mode VCF consisting of two QFX5100-24Qs as spines, two QFX5100-48S as leaf nodes, and one EX4300 as a leaf node. The VCF is working for all devices, except the EX4300 40GbE fabric links will not join the VCF.

In this scenario, what must be corrected to solve the connectivity problem?

8. Which 3 benefits do VXLANs offer to VLANs? (Choose three.)

9. Which statement describes a Juniper Virtual Chassis Fabric?

10. You have configured a DHCP server for ZTP as shown in the exhibit.

Your network contains EX2200 and QFX5100 devices, however, only the EX2200s are receiving the baseline configuration file. You want to ensure that all of the switches in your network receive the baseline configuration file.

Which actions will satisfy this requirement?

11. Referring to the exhibit, R1 and R2 are QFX5100s and are acting as VXLAN Layer 2 Gateways for VLAN 100 using PIM-SM signaling. R2 currently has only the (*.G) state established for VNI 5100.

Which event will cause R2 to establish the (S,G) state for VNI 5100 using R1 as the multicast source?

12. You are building a DCI solution and need both a Layer 2 solution and a Later 3 solution for different workloads within your data centers.

What are two reasons why MPLS would be used a transport for this DCI solution? (Choose two.)

13. Referring to the VCF shown in the exhibit, what is the remote destination trunk weight for the SW-4, SW-1, SW-5 path?

14. You are asked to design a deployment plan for a large number of QFX Series switches using zero touch provisioning (ZTP). The ZTP deployment plan must ensure all switches are upgraded to the desired software version.

Which DHCP option are suboption combination would be used to accomplish this task?

15. A customer notices that all traffic is traveling over a single link within their partially meshed IP Fabric using IBGP. While troubleshooting, the customer notices that the configuration is missing a configuration parameter.

Which parameter would the customer use to solve this problem?

16. You are performing an in-service software upgrade (ISSU) on an QFX5100 Series device.

Which two statements are correct in this scenario? (Choose two.)

17. Which two statements are true regarding IP fabrics?

18. Referring to the exhibit, PE1 and PE2 are acting as MPLS Layer 3 VPN PEs to provide the DCI between DC1 and DC2, which are IP Fabrics. Leaf1 and Leaf2 are QFX5100 Series devices acting as VXLAN Layer 2 Gateways using EVPN signaling for the same VXLAN segment.

Which statement is correct about the Edge1 device in this scenario?

19. You are configuring VXLAN on a network of QFX5100s, and are using the set vlans vlan100 vxlan command: unreachable-vtep-aging-timer 600

What does this command do?

20. Referring to the exhibit, SW-3 and SW-4 have been configured for mixed-mode VCF and added to the VCF. After cabling the new devices into the VCF, you notice that SW-3 automatically joins the VCF, whereas SW-4 does not.

Why are SW-3 and SW-4 behaving this way? (Choose two.)

21. What are three benefits of EVPN that would improve the current E-line, E-LAN, and E-Tree delivery? (Choose three.)

22. Which statement is valid for EVPN multihoming CE1 to PE1 and PE2 as shown in the exhibit?

23. What is the endpoint of a VXLAN tunnel?

24. The MC-LAG group shown in the exhibit is providing high availability services for the directly connected servers.

Where does Juniper Networks recommend you provide the backup liveness detection?

25. A customer has a 3-stage Clos architecture with three spine devices as shown in the exhibit.

If a single spine device fails, what percentage of the remaining bandwidth will be available from leaf node to leaf node?

26. Which two options are network consideration for common VXLAN deployment? (Choose two.)

27. What are two methods used to scale an IBGP IP Fabric? (Choose two.)

28. What are two valid types of VXLAN signaling? (Choose two.)

29. You are building an EVPN Data Center Interconnect. You must support multiple VLANs in a single EVPN instance.

Which parameter provides this functionality?

30. You are deploying MC-LAG as shown in the exhibit.

Which statement is correct when using active/standby mode?
