Question 19 Selectable Answer

You are implementing perimeter security for your data center. You need to inspect all traffic Layer 7 and ensure the failure of a port or device will not result in an interruption to traffic flows.
In this scenario, which design would satisfy these requirements?

A. MX with MC LAG

Question 20 Selectable Answer

You host a multitenant data center that runs VMware. You must perform deep packet inspection
on all inter-tenant traffic that is flowing between the VMs within the same hypervisor. Your solution must provide the security services without needing to leave the physical device.
In this scenario, what should you do to solve this problem?

A. Use separate vswitches to isolate each-tenant's network and use and use a vSRX device to evaluate inter-tenant traffic.
B. Use VLANs to isolate each tenant's networks and use an SRX Series device to evaluate inter-tenant traffic.
C. Use a VLANs to isolate each tenant's network and use IP tables to evaluates inter-tenant traffic.
D. Use a vMX device to isolate each tenant's network and use firewall filters to evaluate inter-tenant traffic.

Question 21 Selectable Answer

You are configuring a DCI VPN solution between sites that require an L3VPN to work with your EVPN deployment. Your organization's policy restricts configuring RSVP and LDP on your WAN links. While configuring the solution, you notice that no routes exist in the inet table.
In this scenario, which parameter will solve this problem?

A. bgp family inet labeled-unicast per-group-label
B. bgp family inet labeled-unicast aggregate-label
C. bgp family inet labeled-unicast resolve-vpn
D. bgp family evpn signaling

Answer:

Question 22 Selectable Answer

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-VR
B. evpn 0 route table on L1 for a default route that will direct the traffic to L2.
C. Examine the INSPECT-VR
D. inet. 0 route table on L1 for a default route that will direct the traffic to L2.
E. Ensure that VRF-1 and INSPECT-VRF route targets on L1 and L2 match.
F. Ensure that the route target in the INSPECT-VRF of L1 matches the route target of the INSPECT- VRF of L2.

Question 23 Selectable Answer

A VXLAN adds 50 to 54 bytes of extra header information to an Ethernet frame.
In this scenario, how would you accommodate this increased?

A. Increase the MTU on the Physical interface connected to the VXLAN network.
B. Increase the MTU on the VTEP interface connected to the VXLAN network
C. Only use switches as VTEPs.
D. Decrease the number VXLANs used

Answer:

Question 24 Selectable Answer

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:

Question 25 Selectable Answer

What happens when a packet is encapsulated by a VXLAN before being placed in the overlay?

A. The TTL is decremented by two and placed in the VXLAN header.
B. The QoS marketing are placed in the VXLAN header.
C. The VLAN-ID is placed in the VXLAN header.
D. A VNI that maps to the VLAN-ID placed in the VXLAN header.

Answer:

Question 26 Selectable Answer

Which two statements describe a VXLAN network identifier (VNI)? (Choose Two)

A. A VNI identifies the inner MAC frame.
B. A VNI identifies a VXLAN segment I
C. A VNI allows only 512 VLANs.
D. A VNI validates the remote VTE
