8. Which two types of tunnels are able to be created on all Junos devices? (Choose two.)

9. The ISP1.inet.0 route table has currently no routes in it.

What will happen when you commit the configuration shown on the exhibit?

10. You are asked to connect an IP phone and a user computer using the same interface on an EX Series switch. The traffic from the computer does not use a VLAN tag, whereas the traffic from the IP phone uses a VLAN tag.

Which feature enables the interface to receive both types of traffic?

11. Which two statements are correct about generated routes? (Choose two.)

12. What is the management IP address of the device shown in the exhibit?

13. Which two BGP attributes must be supported by all BGP implementations and must be included in every update? (Choose two.)

14. You have configured the four EX Series switches with RSTP, as shown in the exhibit. You discover that whenever a link between switches goes up or down, the switches take longer than expected for RSTP to converge, using the default settings.

In this scenario, which action would solve the delay in RSTP convergence?

15. You are asked to create a new firewall filter to evaluate Layer 3 traffic that is being sent between VLANs.

In this scenario, which two statements are correct? (Choose two.)

16. In RSTP, which three port roles are associated with the discarding state? (Choose three.)

17. Referring to the exhibit, why is this OSPF adjacency remaining in this state?

18. Which two statements about BGP facilitate the prevention of routing loops between two autonomous systems? (Choose two.)

19. What is the default MAC age-out timer on an EX Series switch?

20. You have two OSPF routers forming an adjacency. R1 has a priority of 32 and a router ID of 192.168.1.2. R2 has a priority of 64 and a router ID of 192.168.1.1. The routers were started at the same time and all other OSPF settings are the default settings.

Which statement is correct in this scenario?

21. You are concerned about spoofed MAC addresses on your LAN.

Which two Layer 2 security features should you enable to minimize this concern? (Choose two.)

22. A new network requires multiple topology support. You decide to use IS-IS in this situation.

Which three protocol topologies are supported in this scenario? (Choose three.)

23. What is a purpose of using a spanning tree protocol?

24. Which two statements are correct about tunnels? (Choose two.)

25. What is the maximum allowable MTU size for a default GRE tunnel without IPv4 traffic fragmentation?

26. You are attempting to Configure the initial two aggregated Ethernet interfaces on a router but there are no aggregated Ethernet interfaces available.

In this scenario, which configuration will enable these interfaces on this router?

A)

B)

C)

D)

27. You are using OSPF to advertise the subnets that are used by the Denver and Dallas offices. The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets.

Referring to the exhibit, which two statements are correct? (Choose two.)

28. Two routers share the same highest priority and start time.

In this situation, what is evaluated next when determining the

29. Which two statements correctly describe RSTP port roles? (Choose two.)

30. You want to verify pre x information being sent from 10.36.1.4.

Which two statements are correct about the output shown in the exhibit? (Choose two.)

31. What does the * indicate in the output shown in the exhibit?

32. Which statement is correct about IP-IP tunnels?

33. Your BGP neighbors, one in the USA and one in France, are not establishing a connection with each other.

Referring to the exhibit, which statement is correct?

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

35. Which three protocols support BFD? (Choose three.)

36. You need to Configure a LAG between your switches.

In this scenario, which two statements are correct? (Choose two.)

37. Which statement is correct about controlling the routes installed by a RIB group?

38. 1.Referring to the exhibit, which router will become the OSPF BDR if all routers are powered on at the same time?

39. You are configuring an IS-IS IGP network and do not see the IS-IS adjacencies established.

In this scenario, what are two reasons for this problem? (Choose two.)

40. You are a network operator troubleshooting BGP connectivity.

Which two statements are correct about the output shown in the exhibit? (Choose two.)
