NEW QUESTION 5
You are evaluating which method to use for learning MAC addresses in your VXLAN network. Which statement is true in this scenario?

• B. EVPN exchanges MAC addresses through control plane learning and is more reliable than multicast.
• C. EVPN exchanges MAC addresses through data plane learning and is more reliable than multicast.

Answer: B

NEW QUESTION 6
Exhibit.

Referring to the exhibit, you have a data center in which only the spine devices are using EVPN and VXLAN. The leaf nodes are multihomed in active-active mode to the spine nodes through ESI LAG interfaces. In this design, a link failure on the interface connecting the spine nodes would also cause all traffic from the spine to the leaf nodes to drop.
In this scenario, which command configured on which nodes would solve this problem?

• A. the disable protocols evpn no-core-isolation command on the spine nodes
• B. the set protocols evpn no-core-isolation command on the spine nodes
• C. the disable protocols evpn no-core-isolation command on the leaf nodes
• D. the set protocols evpn no-core-isolation command on the leaf nodes

Answer: A

NEW QUESTION 7
Exhibit.

A VXLAN has been created between devices leaf1 and Ieaf3. Referring to the exhibit, which statement is true?

• A. Traffic sent from host1 to host2 will be dropped on Ieaf3.
• B. Traffic sent from host1 to host2 will be tagged with VLAN ID 100 when exiting Ieaf3.
• C. Traffic sent from host1 to host2 will be tagged with VLAN ID 200 when exiting Ieaf3.
• D. Traffic sent from host1 to host2 will be dropped on leaf1.

Answer: B

NEW QUESTION 8
You are deploying a 3-stage Clos IP fabric in your data center. In this scenario, which statement is correct?

• A. Each server-facing interface on a leaf node is always three hops away from other server-facing interfaces.
• B. Each spine node must be physically connected to all other spine nodes.
• C. There is an eight-spine node limitation.
• D. No direct physical connections exist between leaf nodes.

Answer: A

NEW QUESTION 9
What is an advantage that EVPN has over VPLS when used for DC I?

• A. mass MAC withdrawal
• B. transparent BPDU transport
• C. active/standby multihoming
• D. reverse path forwarding

Answer: A

NEW QUESTION 10
Exhibit.

Referring to the exhibit, you must advertise the Io0.12 interface as a type-5 route. Which configuration parameter would be used to accomplish this task?

• C. Configure an export policy to advertise the interface route under protocols evpn.
• D. Configure vrf-table-label under the routing instance.

Answer: C

NEW QUESTION 11
Exhibit.

Referring to the exhibit, what happens when you initiate ZTP on a QFX5120 switch running Junos 21.3R1.9?

• A. ZTP skips both the Junos installation and the configuration.
• B. ZTP performs the Junos installation but skips the configuration.
• C. ZTP performs both the Junos installation and the configuration.
