The boot system command is used to specify the IOS image that a device should load during the boot process. The IOS image can be located in various locations, including RAM, NVRAM, flash memory, HTTP server, TFTP server, or Telnet server. However, only two of these locations can be configured as a source for the IOS image in the boot system command.
The correct answers are C. flash memory and E. TFTP server.
Here's a detailed explanation of each option:
A. RAM: RAM stands for Random Access Memory, which is volatile memory that is used by the device for temporary storage while it is running. The IOS image cannot be stored in RAM permanently, as it will be lost when the device is powered off. Therefore, RAM cannot be configured as a source for the IOS image in the boot system command.
B. NVRAM: NVRAM stands for Non-Volatile Random Access Memory, which is a type of memory that retains its content even when the device is powered off. NVRAM is used to store the device configuration, but it cannot be used to store the IOS image. Therefore, NVRAM cannot be configured as a source for the IOS image in the boot system command.
C. flash memory: Flash memory is a type of non-volatile memory that can be used to store the IOS image permanently. Flash memory is commonly used as a source for the IOS image in the boot system command.
D. HTTP server: HTTP stands for Hypertext Transfer Protocol, which is a protocol used to transfer data over the internet. An HTTP server is a web server that can be used to host files, including IOS images. However, the IOS image cannot be loaded directly from an HTTP server using the boot system command. Instead, the IOS image must be copied from the HTTP server to a local storage location (such as flash memory) before it can be used as a source for the boot system command.
E. TFTP server: TFTP stands for Trivial File Transfer Protocol, which is a protocol used to transfer files over the network. A TFTP server can be used to host IOS images, and it can be configured as a source for the IOS image in the boot system command. The TFTP server must be accessible from the device, and the IOS image must be located in the root directory of the TFTP server.
F. Telnet server: Telnet is a protocol used to establish a remote connection to a device over the network. A Telnet server can be used to manage a device remotely, but it cannot be used as a source for the IOS image in the boot system command.
In summary, flash memory and TFTP server can be configured as a source for the IOS image in the boot system command.
