Question 1

How many port channels can be assigned to a single port?

Answer : D

According to the Dell SONiC documentation, a single physical port can be a member of only one port channel at a time. This restriction ensures the consistency and integrity of link aggregation configurations.

Question 2

What is an iBGP neighbor relationship?

ATwo BGP neighbors have the same autonomous system numbers

BTwo BGP neighbors share L2VPN EVPN advertisements.

CTwo BGP neighbors share only native BGP networks.

DTwo BGP neighbors share only private networks.

Answer : A

An iBGP (Internal Border Gateway Protocol) neighbor relationship is established between two BGP routers within the same autonomous system (AS). This relationship allows for the exchange of routing information within the AS, ensuring that internal routes are propagated correctly.

Question 3

Refer to the exhibit.

Which three actions can a customer take to change interface Eth1/10 to operate in access mode for VLAN 40?

AConfigure the access mode for the switch port.

BDelete VLAN 40.

CShut down the relevant interface.

DRemove the current access VLAN configuration.

EEnter it into the relevant interface.

Answer : A, D, E

Configure the access mode for the switch port (A): This involves setting the switch port to operate in access mode.

Remove the current access VLAN configuration (D): Before changing the VLAN, the current configuration must be cleared.

Enter it into the relevant interface (E): Apply the new configuration to the specific interface, Eth1/10.

Steps:

interface Ethernet 1/10

no switchport access vlan <current VLAN> (Remove current VLAN)

switchport mode access

switchport access vlan 40

Question 4

An administrator issues The ztp enable and show ztp status commands. What two objectives are they trying to accomplish?

AAdministratively enable the ZTP process.

BRemove the ZTP function from the switch.

CDisable the ZTP process.

DCheck on the progress of the ZTP process.

Answer : A, D

The ztp enable command is used to administratively enable the Zero Touch Provisioning (ZTP) process on the switch. This process allows the switch to automatically download and apply configuration files upon boot-up without manual intervention. The show ztp status command is used to check on the progress and status of the ZTP process, providing information about whether the process is active, completed, or encountered any issues.

Question 5

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

ACreate a class-map and attach an ACL with the IP of the next-hop to it.

BCreate an ACL that selects IPs of voice servers

CAttach a policy to the egress interface

DCreate a policy-map and attach the configured class-map and set the next-hop IP

ECreate a class-map and attach that ACL.

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 6

Refer to the exhibit.

What is the purpose of the static route?

AProvide a route to the 12.0.0.0 network.

BProvide a route to the 192.168.45.0 network.

CVerify that the 12.0.0.0 network is active and reachable.

DVerify that devices in VLAN 45 are reachable.

Answer : A

The static route shown in the exhibit S* 12.0.0.0/16 via 192.168.45.254 Vlan45 is used to provide a route to the 12.0.0.0 network. This static route directs traffic destined for the 12.0.0.0/16 network through the gateway at 192.168.45.254, which is associated with VLAN 45. This configuration is typically used to ensure that traffic can reach a specific network via a defined path.

Question 7

SIMULATION

Use the simulator to perform the following configuration task.

1. Map a single-tagged CVLAN 100 to SVLAN 200 translation on PE

switch interface Eth1/1.

2. Map a double-tagged VLAN packet with an outer CVLAN 100 and an

inner dot1q 200 to SVLAN 300 translation on PE switch interface

Eth1/2.

The necessary VLANs and VLAN stacking have already been configured.

Asee the explanation for all step by step solution with all explanation

Answer : A

Here are the steps to configure the required VLAN translations on a Dell SONiC switch:

Map a Single-Tagged CVLAN 100 to SVLAN 200 on Interface Eth1/1:

sonic# configure terminal

sonic(config)# interface Ethernet1/1

sonic(config-if-Ethernet1/1)# switchport mode trunk

sonic(config-if-Ethernet1/1)# switchport vlan mapping 100 200

sonic(config-if-Ethernet1/1)# end

sonic# write memory

Map a Double-Tagged VLAN Packet with Outer CVLAN 100 and Inner dot1q 200 to SVLAN 300 on Interface Eth1/2:

sonic# configure terminal

sonic(config)# interface Ethernet1/2

sonic(config-if-Ethernet1/2)# switchport mode trunk

sonic(config-if-Ethernet1/2)# switchport vlan mapping 100 200 300

sonic(config-if-Ethernet1/2)# end

sonic# write memory

Comprehensive Detailed Step by Step Explanation with Reference:

Enter Configuration Mode:

Access the global configuration mode using the configure terminal command.

Configure Interface Eth1/1:

Enter interface configuration mode for Ethernet1/1 using the command interface Ethernet1/1.

Set the switchport mode to trunk with the command switchport mode trunk.

Configure the VLAN translation using the switchport vlan mapping 100 200 command, which maps CVLAN 100 to SVLAN 200.

Exit the interface configuration mode by typing end.

Save the configuration with write memory.

Configure Interface Eth1/2:

Enter interface configuration mode for Ethernet1/2 using the command interface Ethernet1/2.

Set the switchport mode to trunk with the command switchport mode trunk.

Configure the double-tagged VLAN translation using the switchport vlan mapping 100 200 300 command, which maps packets with outer CVLAN 100 and inner dot1q 200 to SVLAN 300.

Exit the interface configuration mode by typing end.

Save the configuration with write memory.
