Juniper Data Center, Professional Sample Questions:
Question 1
You created an IP Fabric based on IBGP. You noticed that ECMP load sharing is not working.
In this scenario, what is the problem?
A. Each member of the IP Fabric needs a different autonomous system number.
B. BGP route reflectors only reflect the best route.
C. ECMP load sharing is only supported on 40GbE and 100GbE interfaces.
D. A route input policy needs to be added on all non-route reflectors to allow ECMP.
Question 2
You are building a DCI solution and need both a Layer 2 solution and a Later 3 solution for different workloads within your data centers.
What are two reasons why MPLS would be used a transport for this DCI solution? (Choose two.)
A. The fast failover capabilities of MPLS nodes can be accomplished in a recovery time that is equivalent to 50 ms or better.
B. MPLS allows for any-to-any connectivity allowing for both Layer 2 and Layer 3 DCIs.
C. MPLS allows you to natively runnel your own Layer 2 traffic through the service provided
L3VPN.
D. MPLS allows you to interconnect multiple data centers over a public IP network.
Question 3
Referring to the exhibit, each leaf node is a QFX5100 acting as a VXLAN Layer 2 Gateway using EVPN signaling. Leaf 2 and Leaf 3 are both attached to the same EVPN Ethernet segment. Leaf 2 has been elected the designated forwarder for VLAN 200 on that Ethernet segment.
In this scenario, which two actions will Leaf 1 perform with the broadcast Ethernet frame received from Host A? (Choose two.)
A. Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to both Leaf 2 and Leaf 3.
B. Leaf 1 will change the VLAN tag of the Ethernet frame to 200 before encapsulating it in VXLAN.
C. Leaf 1 will strip the VLAN tag from the Ethernet frame before encapsulating it in VXLAN.
D. Leaf 1 will send a VXLAN encapsulated copy of the Ethernet frame to Leaf 2 only.
Question 4
You are performing an in-service software upgrade (ISSU) on an QFX5100 Series device.
Which two statements are correct in this scenario? (Choose two.)
A. The ksyncd process is used to synchronize the state of the master RE to the new backup RE.
B. The mgd process is used to validate system configuration requirements.
C. The vccpd process is used to synchronize the state of the master RE to the new backup RE.
D. The dcd process is used to validate system configuration requirements.
Question 5
Which protocol replicates forwarding information between MC-LAG peers?
A. ICCP
B. LLDP
C. VRRP
D. VCCP
