How many types of NX-OS images are used in Cisco Nexus devices?
You selected the correct answer because there are indeed three types of NX-OS images: the Kickstart Image, which manages hardware initialization, the System Image that contains the full operating system, and the EPLD Image for hardware upgrades.
What is the role of the Kickstart image in NX-OS?
The Kickstart image is vital because it initializes the hardware components and begins the system boot process, ensuring that the device is ready to load the full operating system and operate correctly.
Which command is used to check NX-OS images, device model, and uptime?
You selected “show version” because it effectively provides essential information about the NX-OS images, the device model, and the uptime of the system, which are crucial for managing Cisco Nexus devices efficiently. This command allows you to quickly assess the current operating environment and ensure everything is functioning as expected.
Which command is used to save the running configuration in NX-OS?
You selected “copy run start” because it effectively saves your current running configuration in NX-OS, ensuring that it will remain in place even after the device is rebooted.
How many Spanning Tree Protocol (STP) modes are supported in NX-OS?
NX-OS supports two STP modes: Rapid PVST+ (the default mode) and MST (Multiple Spanning Tree). This dual support allows for flexibility in managing network topologies and optimizing for different scenarios, ensuring reliable network performance
What is the default Spanning Tree Protocol (STP) mode in NX-OS?
You selected “RPVST+” because NX-OS defaults to Rapid PVST+ mode, which optimizes convergence times in networks.
What encapsulation method does NX-OS use for VLAN trunking?
You correctly chose “802.1q” because NX-OS exclusively utilizes this standard for VLAN trunking encapsulation, ensuring compatibility and interoperability in network environments.
What happens if you enter the “write erase” command in NX-OS?
Your selection, “It erases the startup-config but keeps the running-config,” is correct because the “write erase” command effectively removes the saved configuration from memory while maintaining the current active configuration until the device is rebooted.
Which command is used to reboot a Nexus device?
You chose “reload” because it is indeed the correct command to reboot a Nexus switch.
Where can you see the configuration of the management interface (mgmt0)?
You selected “show ip interface brief vrf management” as the correct command because it specifically retrieves the IP information of the mgmt0 interface, which resides in a VRF.
