1. In OSPF, how does a router ensure that LSAs advertised to a neighboring router are received?

LSA flooding guarantees that all routers will receive them successfully.

LSAs are sent over a TCP connection.

LSAs are acknowledged by the neighboring router.

LSAs are advertised with an acknowledgement bit.

2. You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.

In this scenario, which area is needed to accomplish this task?

stub area

non-to-stubby area

3. You are troubleshooting connectivity between an EVPN spine switch configured as a route reflector and a leaf node with an IP address of 10.30.100.6.

The BGP neighbor can advertise EVPN related routes.

The BGP neighbor cannot advertise L3 VPN related routes.

5. 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.)

Verify that the same ESI is configured on the link from the host and that it matches the source.

Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present.

Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present.

Verify that the same ESI is configured on the two links from the source.

6. A modified deficit round-robin scheduler is defined by which three variables? (Choose three.)

priority

WRED

transmit rate

Layer 3 fields

buffer size

7. Referring to the exhibit, which statement is correct when a failure exists on the link between host2 and switch5 on this EVPN-VXLAN fabric?

The switch5 device will send a Type 2 route to all peers.

The switch5 device will send a Type 4 route to all peers.

The switch5 device will send a Type 1 route to all peers.

The switch5 device will send a Type 3 route to all peers.

8. You must ensure that all routes in the 10.0.0/8 address range are not advertised outside of your AS.

Which well-known BGP community should be assigned to these addresses to accomplish this task?

no-export

no-peer

internet

no-advertise

9. Which two statements are correct about the deployment of EVPN-VXLAN on QFX Series devices? (Choose two.)

Type 1 route advertisements always have the single-active flag set to 1.

Junos OS supports underlay replication for BUM traffic forwarding.

Junos OS supports ingress replication for BUM traffic forwarding.

Type 1 route advertisements always have the single-active flag set to 0.

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

The DS-2 switch will be root bridge for MSTI 2.

The DS-1 switch will be root bridge for MSTI 1.

The DS-1 switch will be root bridge for MSTI 2.

The DS-2 switch will be root bridge for MSTI 1.

11. You are asked to establish interface level authentication for users connecting to your network. You must ensure that only corporate devices, identified by MAC addresses, are allowed to connect and authenticate. Authentication must be handled by a centralized server to increase scalability.

Which authentication method would satisfy this requirement?

MAC RADIUS

captive portal

802.1X with single-secure supplicant mode

802.1X with multiple supplicant mode

12. Which three MSTP parameters must match on all switches in the same MST region? (Choose three.)

forwarding delay

bridge priority

revision number

MSTI-to-VLAN mapping

configuration name

13. Which two multicast listener registration protocols are supported in the Junos operating system? (Choose two.)

MLD

DVMRP

IGMP

PIM

14. You are deploying an 802.1X solution and must determine what would happen if clients are unable to re-authenticate to the RADIUS server.

In this scenario, which configuration would provide access to the network if the supplicant is already authenticated?

move

permit

deny

sustain

15. A user is attempting to watch a high-definition video being streamed from the media server over the network. However, the user complains that the experienced video quality is poor. While logged on to router B, a Juniper Networks device, you notice that video packets are being dropped.

In this scenario, what would solve this problem?

Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.

Adjust the expedited-forwarding BA classifier to router B's ge-0/0/0 interface to support a higher transmit rate.

Adjust the scheduler-map to support a higher transmit rate.

Adjust the expedited-forwarding BA classifier on router B's ge-0/0/1 interface to support a higher transmit rate.

16. You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically negotiate the power requirements for the new connection with the EX Series switches.

In this scenario, which protocol should be used to enable this behavior?

CDP

MP-BGP

LLDP-MED

LLDP

17. Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.

Which action would solve this problem?

Configure the links between the access switches and the distribution switch as a trunk port.

Disable the BPDU block function on the access switches.

Disable the BPDU block function on the distribution switch.

Configure a GRE tunnel to encapsulate the L2PT traffic across the WA

18. You are asked to configure 802.1X on your access ports to allow only a single device to authenticate.

In this scenario, which configuration would you use?

single supplicant mode

multiple supplicant mode

single-secure supplicant mode

MAC authentication mode

19. A BGP network has been designed to provide resiliency and redundancy to a multihomed customer network.

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

Both the next hops will be used to forward traffic to R2.

A routing policy will be required to forward traffic to both next hops.

The TTL value of 1 is set to limit the scope of the EBGP session.

The ttl statement must be configured to accommodate peering to a loopback address of a directly connected peer.

20. Referring to the exhibit, ServerA sends a single IP packet destined to 10.0.0.127.

Which two statements correctly describe the behavior of the resulting outbound VXLAN packets that contain the original packet destined to 10.0.0.127? (Choose two.)

Router E will replicate and send a copy of the received VXLAN packet to router

Router C will send a VXLAN packet destined only to router D and router

Router D will not replicate and send a copy of the received VXLAN packet to router

Router C will send a single VXLAN packet to one remote VTE
