• Question 101:

  Your manager asks you to secure ARP and DHCP traffic across your local Ethernet links In this scenario, which technology will accomplish this task?

  A. SSL

  B. MAC sec

  C. IPsec

  D. A firewall filter

  Correct Answer: B

• Question 102:

  You are attempting to configure filter-based forwarding in your data center. All traffic from Host1 that is going to Host2 should be inspected by the data center firewall. You have verified that the traffic is being forwarded from router leaf L1's VRF-1 to its INSPECT-VRF. However, the traffic is not reaching service L2.

  

  Referring to the exhibit, which two steps should you take to troubleshoot the problem? (choose two.)

  A. Examine the INSPECT-VRF.evpn 0 route table on L1 for a default route that will direct the traffic to L2.

  B. Examine the INSPECT-VRF.inet. 0 route table on L1 for a default route that will direct the traffic to L2.

  C. Ensure that VRF-1 and INSPECT-VRF route targets on L1 and L2 match.

  D. Ensure that the route target in the INSPECT-VRF of L1 matches the route target of the INSPECT- VRF of L2.

  Correct Answer: BD

• Question 103:

  You are configuring an EVPN overlay network. You want to ensure that leaf devices can respond to ARP requests from locally connected hosts, when the leaf device knows the MAC of the intended destination. In this scenario, what should you configure on the leaf devices to accomplish this task?

  A. Proxy ARP

  B. Static ARP entries

  C. Persistent MAC learning

  D. IGMP snooping

  Correct Answer: A

  C. RSTP

  D. MPLS

  Correct Answer: AB

• Question 105:

  An EVPN-signaled VXLAN overlay has been deployed in the network shown in the exhibit. An EVPN LAG has been configured to connect host1 to the network, and device leaf1 has been elected as the designated forwarder.

  

  In this scenario, which statement is true?

  A. The Ieaf3 device can utilize both leaf1 and Ieaf2 to forward unicast packets from host2 to host1.

  B. An ICCP control link must be configured between leaf1 and Ieaf2.

  C. The Ieaf3 device will only receive an advertisement to the LAG segment from leaf1.

  D. Broadcast packets sent from host2 will not be forwarded to Ieaf2.

  Correct Answer: C

• Question 106:

  You have a two spine and four leaf CRB topology and you must ensure that the hosts connected to the leaf devices have reachability to all IRB interface addresses, including the local spine IRB addresses, and the virtual gateway address. Which two configuration parameters must be used to accomplish this task? (Choose two.)

  A. Configure a spine-to-spine BGP peering as part of the overlay.

  B. Configure virtual-gateway-accept-data under the IRB interface.

  C. Configure a spine-to-spine EVPN peering as part of the routing instance.

  D. Configure proxy-macip-advertisement under the IRB interface.

  Correct Answer: BD

• Question 107:

  You are asked to design a deployment plan for a large number of QFX Series switches using ZTP. The ZTP deployment plan must ensure all switches are configured with their designated configuration file.

  Which DHCP option and subscription combination would be used to accomplish this task?

  A. DHCP option 43 a suboption of 00.

  B. DHCP option 66 a suboption of 01.

  C. DHCP option 66 a suboption of 00.

  D. DHCP option 43 a suboption of 01.

  Correct Answer: D

  Which EVPN router type prevents BUM traffic from looping back to a multihued host?

  A. Ethernet segment router

  B. IP prefix route

  C. Ether auto discovery route

  D. Inclusive multicast-Ethernet tag route

  Correct Answer: C

• Question 109:

  Which two statements are true Virtual Chassis? (Choose two.)

  A. By default, Junos switches are in non-mixed mode virtual chassis.

  B. The request virtual-chassis mode fabric reboot command will set the Virtual Chassis to fabric mode with similar devices

  C. By default, Junos switches are in a mixes mode Virtual Chassis

  D. The request virtual-chassis mode fabric reboot command will set the Virtual Chassis to mixed mode.

  Correct Answer: CD

• Question 110:

  B. Hosts in VLAN 10 can communicate with hosts in Data Center 2 using Layer 2.

  C. Hosts in VLAN 202 can communicate using Layer 3 between data centers.

  D. Hosts in VLAN 202 can communicate using Layer 2 between data centers.

  Correct Answer: AD
