Interface Numbering/SSH/UserAccounts

Question 1

What keyword is used to represent every interface in a Nexus device?

Answer 1

You selected “Eth (Ethernet)” because in Nexus devices, the keyword “Ethernet” is used to represent all interface types, regardless of their speed.

Question 2

What is the starting number for interface numbering in Nexus devices?

Answer 2

You selected “1” because Nexus devices indeed start interface numbering from 1, such as Eth1/1 and Eth2/1.

Question 3

Which command is used to check interface capabilities and details of a single port?

Answer 3

You selected “show interface INT-NUMBER” because it specifically provides comprehensive details about a single interface, including its speed, status, and configuration.

Question 4

How many default VRFs exist in a Nexus device?

Answer 4

You selected “2” because there are indeed two default VRFs, which are “default” and “management,” in Nexus devices.

Question 5

What is the default status of the Telnet service on a Nexus device?

Answer 5

You selected “Disabled” because, in Nexus devices, the Telnet service is indeed disabled by default for security reasons. This ensures that you need to actively enable it using the command “feature telnet” to ensure secure access to your devices.

Question 6

What command is used to enable Telnet service on a Nexus device?

Answer 6

You selected “feature telnet” because it is the correct command to enable the Telnet service in Nexus devices, allowing you to access the device remotely through Telnet.

Question 7

Which service is enabled by default in Nexus devices?

Answer 7

You selected “SSH” because it is indeed enabled by default in Nexus devices, which allows for secure remote management.

Question 8

What is the default RSA key size generated in a Nexus device?

Answer 8

You selected “1024-bit” because Nexus devices default to generating a 1024-bit RSA key, which strikes a balance between security and performance.

Question 9

What must be done before changing the RSA key on a Nexus device?

Answer 9

You selected “Disable SSH” because before changing the RSA key on a Nexus device, it’s necessary to disable the SSH feature using the command “no feature ssh.” This step prevents errors when generating a new RSA key, ensuring a smooth configuration process

Question 10

How do you create a user account in Nexus?

Answer 10

You selected “username USERNAME password PASSWORD role ROLE-NAME” because it correctly follows the syntax required by NX-OS for creating a user account, highlighting your understanding of user management in this operating system.
