QUESTION 33
You have configured CoS on a Junos device. A packet is classified as best effort by a behavior aggregate (BA) classifier, and as expedited forwarding by a multifield (MF) classifier.
Which statement is true in this scenario?

The packet will be placed in a queue associated with the BA classifier.

The packet will be placed into the queue which is least congested.

The packet will be placed into the queue that has the most bandwidth assigned to it.

The packet will be placed in a queue associated with the MF classifier.

>> “If you configure both a behavior aggregate (BA) classifier and a multifield classifier, BA classification is performed first; then multifield classification is performed. If they conflict, any BA classification result is overridden by the multifield classifier.”

Source, R1, R2, R5, R2, R3, R6 Receiver

Source, R1, R2, R3, R6, Receiver

Source, R1, R2, R5, R6, Receiver

QUESTION 37
Which protocol is used for port-level access control and authentication?

MD5

IPsec

802.1x

AES

QUESTION 38
Packets enter a Juniper device and are classified as best effort. During the processing of the packet, the classification of the packets is changed to expedited forwarding by a multi-field classifier. The device is using the default CoS policies Which statement is true in this scenario?

The packet is forwarded according to the new packet classification, and the DSCP bits are rewritten to the new class.

The packet is forwarded according to the new packet classification, and the DSCP bits do not change.

The packet is forwarded according to the original packet classification, and the DSCP bits do not change.

The packet is forwarded according to the original packet classification, and the DSCP bits are rewritten to the new class.

QUESTION 39
Referring to the exhibit, there are multiple ASM groups in the 224 0 0.0/4 range Which configuration change is needed to ensure R1 is always the RP for group 224.224.1.1?

Increase the priority on R1 to higher than R2

Configure R1 with a higher local RP address

Set the priority on R1 to zero

Ensure R1 has a more specific group range

QUESTION 40
You are authenticating user devices connected to your ex Series switch. You have 802.1X and MAC RADIUS configured for all ports. A user is complaining about the time it takes to connect their non- 802.1X device on ge-0/0/15 using MAC RADIUS authentication.

QUESTION 44
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.

Type 2 route, MAC with IP advertisement route-Type 2 routes are per-VLAN routes, so only PEs that are part of a VNI need these routes. EVPN allows an end host’s IP and MAC addresses to be advertised within the EVPN Network Layer reachability information (NLRI). This allows for control plane learning of ESI MAC addresses. Because there are many Type 2 routes, a separate route-target auto-derived per VNI helps to confine their propagation. This route type is supported by all EVPN switches and routers. Type 5 route, IP prefix Route-An IP prefix route provides encoding for inter-subnet forwarding. In the control plane, EVPN Type 5 routes are used to advertise IP prefixes for inter-subnet connectivity across data centers. To reach a tenant using connectivity provided by the EVPN Type 5 IP prefix route, data packets are sent as Layer 2 Ethernet frames encapsulated in the VXLAN header over the IP network across the data centers.

QUESTION 45
Which protocol allows a switch to pass configuration information to an IP phone?

VCCP
