For what two reasons has the router loaded its IOS image from the location that is shown?
(Choose two.)

A.
Router1 has specific boot system commands that instruct it to load IOS from a TFTP server.
Run boot system commands in order they appear in startup-config to locate the IOS
Flash (sequential)
No configuration file was found in NVRAM.

B.
Router1 is acting as a TFTP server for other routers.
[If boot system commands fail, use default fallback sequence to locate the IOS (Flash, TFTP,
ROM)?]
If no boot system commands in startup-config use the default fallback sequence in locating the
IOS:
TFTP server (netboot)
No configuration file was found in flash.

C.
Router1 cannot locate a valid IOS image in flash memory.
ROM (partial IOS) or keep retrying TFTP depending upon router model
5. If IOS is loaded, but there is no startup-config file, the router will use the default fallback
sequence for locating the IOS and then it will enter setup mode or the setup dialogue.
QUESTION 176
Refer to the exhibit.

What can be determined about the router from the console output?
No configuration file was found in the PCMCIA card.

D.
Router1 defaulted to ROMMON mode and loaded the IOS image from a TFTP server.
Configuration file is normal and will load in 15 seconds.

E.
Cisco routers will first attempt to load an image from TFTP for management purposes.

Explanation:
The loading sequence of CISCO IOS is as follows:
Booting up the router and locating the Cisco IOS
1. POST (power on self test)
2. Bootstrap code executed
3. Check Configuration Register value (NVRAM) which can be modified using the config-register
command
0 = ROM Monitor mode
1 = ROM IOS
2 – 15 = startup-config in NVRAM

4. Startup-config filE. Check for boot system commands (NVRAM)
If boot system commands in startup-config

When no startup configuration file is found in NVRAM, the System Configuration Dialog will appear
to ask if we want to enter the initial configuration dialog or not.
