Q8: Core Devices and Concepts Flashcards
Where does a Cisco device store its iOS locally?
A. RAM
B.DRAM
C. FLASH
D. NVRAM
C) Flash
Explanation: The iOS image for a Cisco device can be stored in various places including on the device or even on a tftp server. If the iOS is stored locally on the device, then it will be in the flash file system.
Where is the startup- config located on a Cisco router?
A. RAM
B. DRAM
C. FLASH
D. NVRAM
D) NVRAM
Explanation: When you save the running=config on a Cisco iOS device, a copy of the running configuration get saved in a special memory location called NVRAM, or, Non-Volatile RAM. NVRAM is onboard memory that retains its integrity even if the device gets powered off. Anything in RAM will be lost during a reboot, but NVRAM is preserved.
The iOS for a Cisco router is loaded into ——- when the router is booted.
A. RAM
B. DRAM
C. FLASH
D. NVRAM
A) RAM
Explanation: In order to load and run an iOS image, a Cisco device must load the iOs image from flash into RAM. The iOS file is then run in RAM. if the device reboots, then the contents of RAM will be lost and a new copy of the iOS will be loaded into RAM upon bootup.
When would you need a USB adapter for a console cable?
A. When trying to access the console port remotely
B. When the Laptop or PC doesn’t have an RS-232 serial port
C. When accessing the device via the AUX port rather than the CON port
D. When you are using a non-Cisco console cable
E. When console cable is crossed over instead of rolled over
B) When a Laptop or PC doesn’t have an RS-232 serial port
Explanation: Older console cables will have an rs-232 (DB-9) serial connector on the PC end and an RJ-45 connector on the device console port end. Any laptop made in recent years will not have an RS-232 port. Instead, the console cable would have to connect via the PC’s USB port- which could require an adapter and most likely software drivers
Which of the following Cisco devices does not have a console port built into the chassis?
A. 4300 series Router
B. 5500 series ASA
C. 7900 series IP phone
D. 3560 Layer 3 switch
C) 7900 series IP phone
Explanation: Most iOS devices have a physical console port through which you can access the device for configuration. Cisco IP phone do not have a console port through which to configure them. Instead, they have a physical display and key-based input functions by which the phone can be configured.
