Question #41
An administrator issues The ztp enable and show ztp status commands.
What two objectives are they trying to accomplish?
- A . Administratively enable the ZTP process.
- B . Remove the ZTP function from the switch.
- C . Disable the ZTP process.
- D . Check on the progress of the ZTP process.
Correct Answer: A D
A D
Explanation:
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.

The route distinguisher was autogenerated.
Which VLAN is mapped to VNI410?
- A . VLAN 410
- B . VLAN41
- C . VLAN 10
- D . VLAN 26
Correct Answer: C
C
Explanation:
The route distinguisher (RD) in the exhibit is 10.0.2.26:41. The RD typically reflects the VNI and VLAN mapping configuration. Given that the VNI is 410 and the RD ends with :41, it implies that VLAN 10 is mapped to VNI 410.

Question #47
An administrator obtains the following CLI output:
How much time does the local system take to detect remote failures without receiving packets?
- A . 600 milliseconds
- B . 900milliseconds
- C . 1200 milliseconds
- D . 800 milliseconds
Correct Answer: B
B
Explanation:
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.

What is the primary VRRP router for VRRP group 10?
- A . Router-1
- B . Router-2
- C . Router-3
Correct Answer: B
B
Explanation:
Based on the exhibit, Router-2 has the highest priority (90) in VRRP group 10. In VRRP, the router with the highest priority becomes the primary (master) router. Therefore, Router-2 is the primary VRRP router for VRRP group 10.

Question #49
What interface must be selected when configuring the management port from within the MF-CLI environment?
- A . mgmt 1/1/1
- B . ma 0/1
- C . Management 0
- D . eth0
Correct Answer: D
D
Explanation:
Dell SONiC Management Interface Configuration:
In Dell SONiC, the management port configuration is a crucial aspect that allows administrators to access and manage the network device.
The management interface typically provides out-of-band management access to the device, ensuring that even if the data network is down, the management network can still be accessed.
Common Interface Naming Conventions:
mgmt 1/1/1: This naming convention is not typically used in Dell SONiC environments for management interfaces.
ma 0/1: This could be a potential naming convention but is not standard for Dell SONiC.
Management 0: This is a logical name but does not align with the standard interface naming conventions used in Dell SONiC.
eth0: This is the standard naming convention used for the primary management interface in most Linux-based systems, including Dell SONiC.
Verification with Dell SONiC Documentation:
Dell SONiC documentation specifies that the management interface is usually named eth0.
When accessing the management interface within the MF-CLI (Management Framework Command Line Interface) environment, eth0 is the correct interface to configure.
Practical Configuration Example:
When configuring the management port, the command might look something like:
config interface ip add eth0 <management_ip_address>/<subnet_mask>
This command specifies the management interface eth0 and assigns it an IP address for network management purposes.
