Question No. 1

SIMULATION

VLAN 40 is configured in Switch A with an anycast-address of 192.168.40.254/24. The ARP neighbor suppression is enabled. Use the simulator to create a VTEP named vtep1 and assign an IP address of

10.10.10.1. Map the VNI 400 to VLAN 40.

Show Answer Hide Answer
Correct Answer: A

Here are the steps to create the VTEP and map the VNI to the VLAN:

Enter Configuration Mode:

SwitchA# configure terminal

Create VTEP Interface:

SwitchA(config)# interface vtep1

SwitchA(config-if-vtep1)# ip address 10.10.10.1/24

SwitchA(config-if-vtep1)# exit

Map VNI 400 to VLAN 40:

SwitchA(config)# vlan 40

SwitchA(config-vlan)# vn-segment 400

SwitchA(config-vlan)# exit

Enable ARP Neighbor Suppression:

SwitchA(config)# interface Vlan40

SwitchA(config-if-Vlan40)# ip address 192.168.40.254/24

SwitchA(config-if-Vlan40)# vxlan arp-suppression

SwitchA(config-if-Vlan40)# exit

Save Configuration:

SwitchA# write memory

Enter Configuration Mode:

Begin by entering the global configuration mode to make changes to the switch configuration.

Create VTEP Interface:

Enter the interface configuration mode for the VTEP interface named vtep1 using interface vtep1.

Assign the IP address 10.10.10.1/24 to the VTEP interface using the ip address command.

Exit the interface configuration mode.

Map VNI 400 to VLAN 40:

Enter the VLAN configuration mode for VLAN 40 using vlan 40.

Map the VNI 400 to VLAN 40 using the vn-segment 400 command.

Exit the VLAN configuration mode.

Enable ARP Neighbor Suppression:

Enter the interface configuration mode for VLAN 40 using interface Vlan40.

Assign the anycast IP address 192.168.40.254/24 to the VLAN interface using the ip address command.

Enable ARP neighbor suppression using the vxlan arp-suppression command.

Exit the interface configuration mode.

Save Configuration:

Save the configuration to ensure the changes persist after a reboot using the write memory command.

These steps provide a comprehensive guide to configure a VTEP and map the VNI to VLAN 40 on Switch A, ensuring the specific requirements for IP addressing and ARP neighbor suppression are met.

Question No. 2

An administrator obtains the following CLI output:

How much time does the local system take to detect remote failures without receiving packets?

Show Answer Hide Answer
Correct Answer: B

The local timers in the BFD (Bidirectional Forwarding Detection) configuration show a detect multiplier of 4 and a receive interval of 300ms. The time taken to detect remote failures is calculated as detect multiplier receive interval = 4 300ms = 1200ms.

Question No. 3

Which three actions are required to route traffic sourced from voice servers to a dedicated Internet link''

Show Answer Hide Answer
Correct Answer: B, C, D

To route traffic from voice servers to a dedicated Internet link, the following steps are necessary:

Create an ACL that selects IPs of voice servers (B): This ACL will match the traffic coming from the specified IP addresses of the voice servers.

Create a policy-map and attach the configured class-map and set the next-hop IP (D): The policy-map will use the class-map to identify the voice server traffic and then set the next-hop IP for routing.

Attach a policy to the egress interface (C): The policy-map must be applied to the egress interface to ensure that the traffic is routed correctly.

Question No. 4

What are three characteristics of VLAN translation?

Show Answer Hide Answer
Correct Answer: A, B, E

VLAN translation is not supported on MC-LAG port channel interfaces (A): This is a restriction commonly seen in network configurations involving Multi-Chassis Link Aggregation (MC-LAG) where VLAN translation capabilities are not applied.

Trunk or access ports can be configured as members of any VLANs that are not used as an SVLAN (B): This ensures that the VLAN configuration on trunk or access ports is flexible and does not overlap with Service VLANs (SVLANs).

SVLAN configuration for both Q-in-Q VLAN tunneling and VLAN translation is possible on the same interface (E): This allows for complex VLAN tagging and translation configurations to be applied to the same interface, supporting advanced networking scenarios.

Question No. 5

What two methods can be used to upgrade or downgrade Enterprise SONiC?

Show Answer Hide Answer
Correct Answer: A, D

Enterprise SONiC can be upgraded or downgraded using:

Boot Loader (A): The boot loader can be used to select and load different versions of the SONiC firmware.

GRUB (D): GRUB (Grand Unified Bootloader) is another method used to manage and select different SONiC firmware versions during system boot-up.
