Default VSTP bridge priority values are configured.

NO.65 Referring to the exhibit, anycast RP is implemented to ensure multicast service availability. The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information.
In this scenario, what are two methods to receive the active source information on R2? (Choose two.)

Configure an RP set in PIM on R1, allowing R1 to forward PIM register messages to R2 and R3 in the set.

Configure an MSDP protocol between R2 and R3.

Configure an RP set in PIM on R2 and R3, allowing the RPs to forward PIM register messages to the other RPs in the set.

Configure an MSDP protocol between R1 and R2.

NO.66 You have an MX960 configured as a Fusion aggregation device (AD) and two QFX5100 switches as satellite devices (SD). You have configured local-switching for each SD. A packet with an unknown MAC address is received on one of the SD extended ports.
Which statement is correct in this scenario?

The packet is dropped and a reject message is sent out to the port where it was received.

The packet is silently discarded and a reject message is sent to the AD.

The packet is flooded out of all the ports on the SD except the one where it was received.

The packet is sent to the AD to be processed and forwarded.

NO.67 Which statement is correct about IS-IS?

IS-IS uses areas and an autonomous system.

Level 1/2 routers automatically inject a default route to the nearest Level 1 router.

Level 2 routers must share the same area address.

Level 1 routers route traffic between autonomous systems.

NO.68 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 D.

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

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

Router C will send a single VXLAN packet to one remote VTEP.

NO.69 Which address range is used for source-specific multicast?

239.0.0.0/8

233.0.0.0/8

232.0.0.0/8

224.2.0.0/16

NO.70 You are asked to troubleshoot voice quality issues on your newly implement VoIP network. You notice that the voice packets are being dropped. You have verified that the packets are correctly marked for expedited forwarding queue.
Referring to the exhibit, what must you configure to solve the problem?

You must configure a multifield classifier to put the VoIP traffic in the correct queue.

You must configure a rewrite rule to ensure that the traffic is scheduled properly in the device.

You must configure a scheduler to allocate bandwidth to the expedited forwarding queue.

You must configure a policer to ensure that the queue is not being starved.

NO.71 You enable the Multiple VLAN Registration Protocol (MVRP) to automate the creation and management of virtual LANs.
Which statement is correct in this scenario?

The forbidden mode does not register or declare VLANs.

When enabled, MVRP affects all interfaces.

Timers dictate when link state changes are propagated.

MVRP works with RSTP and VSTP.

NO.72 Which two port modes are associated with STP? (Choose two.)

alternate port

backup port

designated

root

NO.73 Your network is multihomed to two ISPs. The BGP sessions are established; however, the ISP peers are not receiving any routes.
Which two statements are correct about troubleshooting your configuration? (Choose two.)

Verify the import policies on your router.

Verify that the BGP routes are active in your routing table.

Verify the export policies on your router.

Verity that the multihop settings are configured on your router.

NO.74 Click the Exhibit button.

The host that the route is associated with is multihomed to two leaf nodes.

The route is a Type 1 EVPN route.

The route is a Type 2 EVPN route.

The host that the route is associated with is single-homed to one leaf node.

NO.77 Referring to the exhibit, you have placed the cos multifield classifier on all edge interfaces and configured the relevant CoS parameters.
In this scenario, which two statements are correct? (Choose two.)

SSH traffic using the default port will be placed in the af forwarding class and accepted.

SSH traffic using the default port will be placed in the best-effort forwarding class and accepted.

UDP traffic using the 16000 port will be placed in the voice forwarding class and accepted.

UDP traffic using the 16000 port will be placed in the best-effort forwarding class and accepted.

NO.78 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?
