Question 1

Exhibit.

Both DC and DC2 ate using EVPN-VXLAN technology deployed using an ERB architecture. A server on the Red VLAN must communicate with a server on the Green VLAN. The Blue VLAN in DC and DC2 needs to be the same VLAN. Which statement is correct in this scenario?

Options :

A :

The eight spine devices must be configured as border spine devices; a full mush interconnect must exist between all eight spine devices and the Blue VLAN must be stitched together

B :

An interconnect is required between the four SRX Series devices; the Blue VLAN must be stretched and a transit VNI must be added for the Red and Green VLANs.

C :

An interconnect is required between four leaf devices in the services blocks; the Red VLAN and the Green VLAN must be stitched and the Blue VLAN must be stretched.

D :

A lean super spine device must be added to DC and DC2; all VLANs must be stretched to the lean super spine device and the lean super spine devices must stitch all the VLANs together

Answer: B

Question 2

Exhibit.

A VXLAN tunnel has been created between leaf1and Ieaf2 in your data center. Referring to the exhibit, which statement is correct?

Options :

A : Traffic sent from server1to server2 will be dropped on Ieaf2.

B :

Traffic sent from server1to server2 will be tagged with VLAN ID 100 on Ieaf2 and forwarded to server2.

C :

Traffic sent from server1to server2 will be tagged with VLAN ID 200 on Ieaf2 and forwarded to server2.

D : Traffic sent from server1to server2 will be dropped on leaf1.

Answer: C

Question 3

You are asked to identify microburst traffic occurring in the network leading lo packet drops in your data center switches Which two tools would be used in this scenario? (Choose two.)

Options :

A : port mirroring

B : Traceoptions

C : port buffer monitoring

D : syslog

Answer: A,C

Question 4

You are selling up an EVPN-VXLAN architecture (or your new data center. thisinitial deployment will be less than 50 switches: however, it could scale up to 250 switches over time supporting 1024 VLANs. You are still deciding whether to use symmetric or asymmetric routing. In this scenario, which two statements are correct? (Choose two.)

Options :

A : Symmetric routing needs an extra VLAN with an IRB interface for each L3 VRF instance.

B : Asymmetric routing is easier lo monitor because of the transit VNI.

C : Symmetric routing supports higher scaling numbers.

D : Asymmetric routing routes traffic on the egress switch.

Answer: C,D

Question 5

Exhibit.

Host A is connected to vlan 100 on lead. Host B is connected to vlan 200 on leaf1. Host A and Host B ate unable to communicate. You have reviewed the touting and your hosts have the correct default route (.1) Referring to the exhibit, which two commands will solve the problem? (Choose two.)

Options :

A : delete vlans vn200 13-interface irb.200

B : set interfaces irb unit 100 family inet address 192-168.100.1

C : set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10

D : set vlans vn10013-interface irb.100

Answer: C,D
