Demo Questions

Question 1
Click the Exhibit button.
You are troubleshooting an IP fabric for your data center. You notice that your traffic is not being load balancing to your spine devices from leaf devices.
Referring to the configuration shown in the exhibit, what must be configured to solve this issue?
  1. The load-balance policy must have a from statement that matches on protocol bgp.
  2. The multipath multiple-as configuration must be configured for each peer in the BGP spine group.
  3. The load-balance policy must be applied as an export policy to your BGP spine group.
  4. The load-balance policy must be applied to the forwarding table under the routing-options hierarchy.

Question 2
Which two statements are true about IP fabrics using unnumbered BGP? (Choose two.)
  1. Unnumbered BGP peering automatically provisions IPv4 peering.
  2. Unnumbered BGP requires that family inet6 is configured on each interface.
  3. Unnumbered BGP peering automatically provisions IPv6 peering.
  4. Unnumbered BGP requires that family inet is configured on each interface.

Question 3
You are deploying a Clos IP fabric with an oversubscription ratio of 3:1.
In this scenario, which two statements are correct? (Choose two.)
  1. The oversubscription ratio decreases when you add spine devices.
  2. The oversubscription ratio increases when you remove spine devices.
  3. The oversubscription ratio remains the same when you add spine devices.
  4. The oversubscription ratio remains the same when you remove spine devices.

Question 4
You are asked to set up an IP fabric that supports AI or ML workloads. You have chosen to use lossless Ethernet.
In this scenario, which statement is correct about congestion management?
  1. The switch experiencing the congestion notifies the source device.
  2. Only the source and destination devices need ECN enabled.
  3. ECN marks packets based on WRED settings.
  4. ECN is negotiated only among the switches that make up the IP fabric for each queue.

Question 5
You are designing an IP fabric for a large data center, and you are concerned about growth scalability.
Which two actions would you take to address these concerns? (Choose two.)
  1. Use EX4300 Series devices as the spine devices.
  2. Design a three-stage Clos IP fabric.
  3. USE QFX5700 Series devices as the super spines.
  4. Design a five-stage Clos IP fabric.

Question 6
Click the Exhibit button.
You have implemented an EVPN-VXLAN data center. Device server1 must be able to communicate with device server2.
Referring to the exhibit, which two statements are correct? (Choose two.)
  1. Traffic from server1 to server2 will transit a VXLAN tunnel to spine1 or spine2, then a VXLAN tunnel from spine1 or spine2 to leaf2.
  2. Traffic from server1 to server2 will transit the VXLAN tunnel between leaf1 and leaf2.
  3. An IRB interface must be configured on leaf1 and leaf2.
  4. An IRB interface must be configured on spine1 and spine2.

Question 7
A local VTEP has two ECMP paths to a remote VTEP.
Which two statements are correct when load balancing is enabled in this scenario? (Choose two.)
  1. The inner packet fields are not used in the hash load balancing.
  2. The destination port in the UDP header is used to load balance VXLAN traffic.
  3. The source port in the UDP header is used to load balance VXLAN traffic.
  4. The inner packet fields are used in the hash for load balancing.
Correct answer: CD

Question 8
Click the Exhibit button.
Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.
Referring to the exhibit, which two configuration changes are required to solve the problem? (Choose two.)
  1. Configure the set switch-options vrf-target target:65000:1 parameter on Leaf-2.
  2. Configure the set switch-options service-id 1 parameter on Leaf-2.
  3. Configure the set switch-options vtep-source-interface irb.0 parameter on Leaf-1.
  4. Configure the set switch-options route-distinguisher 192.168.100.50:1 parameter on Leaf-1.

Question 9
Click the Exhibit button.
A VXLAN tunnel has been created between leaf1 and leaf2 in your data center.
Referring to the exhibit, which statement is correct?
  1. Traffic sent from server1 to server2 will be dropped on leaf2.
  2. Traffic sent from server1 to server2 will be dropped on leaf1.
  3. Traffic sent from server1 to server2 will be tagged with VLAN ID 200 on leaf2 and forwarded to server2.
  4. Traffic sent from server1 to server2 will be tagged with VLAN ID 100 on leaf2 and forwarded to server2.

Question 10
Click the Exhibit button.
Referring to the exhibit, why is the active source field blank for the entry that uses the 00:0c:29:e8:b7:39 MAC address?
  1. The host for this entry is locally connected to leaf1.
  2. The ARP lookup for this host has failed.
  3. The EVPN route for this host does not have a valid next hop.
  4. This entry is associated with a multicast EVPN route.
