QUESTION 6
You are deploying a spine-and-leaf IP Fabric in your data center using EBGP. In this scenario, which three statements are true? (Choose three.)
A. Each device should you use a different autonomous system number.
B. Each leaf must peer to each spine.
C. Each device should also run an IGP to advertise loopback interfaces.
D. EBGP does not require a next-hop self-policy.
E. Each leaf must peer to every other leaf.

QUESTION 7
VMs on Server-1 and Server-2 are on the same Layer 2 domain within a VCF and are sending traffic to each other.
Referring to the exhibit, which three criteria are used when load-balancing traffic? (Choose three.)
A. EtherType
B. source MAC
C. incoming port ID
D. Layer 4 source port
E. destination IP
Answer: ABC
Explanation:
http://nextheader.net/2016/10/28/virtual-chassis-fabric-part-ii-control-and-forwarding-plane/
Layer 2 load-balancing hashing does not involve Layer 3 or Layer 4 header information. I.E.: Layer 2: source MAC, destination MAC, Ethertype, Vlan ID, Incoming Port ID, source member ID.
QUESTION 8
You are deploying MC-LAG as shown in the exhibit.
Which statement is correct when using active/standby mode?
A. A spanning tree protocol should be used to avoid Layer 2 loops between Server A and both switches.
B. VCCP is used to exchange MAC addresses between MC-LAG peers.
C. All traffic from Server A to Host 1 will traverse the link between Server A and ex2.
D. Only ICCP control traffic is allowed through the ICL-PL connection.
Answer: D

QUESTION 9
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?
A. R2 will send a (*.G) PIM Join when its VLAN 100 configuration is committed.
B. R2 will send a (*.G) PIM Join when it first learns the MAC address of a locally attached host.
C. R2 will send a (*.G) PIM Join when it receives broadcast, multicast, or unknown unicast traffic from Host B.
D. R2 will send a (*.G) PIM Join when it receives broadcast, multicast, or unknown unicast traffic from Host A.
Answer: A
Explanation:
https://www.juniper.net/documentation/en_US/junos/topics/concept/multicast-pim-sparse-characteristics.html
It’s A because if you consider that Host B may send zero traffic whatsoever, how can Host A find Host B’s MAC address? It would have to ARP for it. So, because Host B may lie dormant until Host A initiates communications, it is completely necessary for R2 to (*,G) PIM Join the VXLAN group for VLAN 100. C is impossible before the (*,G), B and D are shades of the same chicken-and-egg scenario that makes A the only viable answer.
QUESTION 10
You are using IBGP to deploy an IP fabric. There are four spine devices, two of which are configured as route reflectors. You notice that the other two spines are not receiving all the possible paths to each leaf, and traffic cannot be load-balanced to the leaf devices. Which two actions will resolve this problem? (Choose two.)
A. Configure the add-path parameter on the leaf devices.
B. Configure the multihop parameter on the route reflectors.
C. Configure the multipath parameter on the route reflectors.
D. Configure the add-path parameter on the route reflectors.
Answer: AD
