change the type of antenna attached to the AP

move the wireless AP to a secure VLAN

move the wireless AP to a port on a Layer 3 switch

 

11. A production router is reloaded and finishes with a Router> prompt. What three facts can be determined? (Choose three.)

POST occurred normally.

The boot process was interrupted.

There is not enough RAM or flash on this router.

The configuration register may have a value of 0x2142.

A full version of the Cisco IOS was located and loaded.

The router did not locate the Cisco IOS in flash, so it defaulted to ROM.

 

12.

Refer to the exhibit. What two items can be determined from the output? (Choose two.)

R2 is a Cisco 2600 device.

R2 has 22 MB of RAM installed.

The version of the IOS is 12.3.

Over 8 MB of NVRAM is installed.

A new 36 MB IOS file can be installed on the device.

 

13.

Refer to the exhibit. If a reload command is issued on router FC-CPE-1, where does the router first search fo the Cisco IOS image?

NVRAM

flash

RAM

TFTP server

 

14.

Refer to the exhibit. A network administrator issues the command shown to gain knowledge about a poorly documented network. Which two pieces of information can the network administrator discover from the command output? (Choose two.)

One connected device has router capability.

The entire network contains a total of five Cisco devices with CDP enabled.

None of the directly connected network devices have been configured with an IP address.

Device EDGE_2811 is connected to port Fast Ethernet 0/0 on device C3750-24_MDF.

Five Cisco devices with CDP enabled are directly connected to device C3750-24_MDF.
