Refer to the exhibit. A network engineer is preparing to upgrade the IOS system image on a Cisco 2901 router. Based on the output shown, how much space is available for the new image?
The customer of a networking company requires VPN connectivity for workers who must travel frequently. To support the VPN server, the customer router must be upgraded to a new Cisco IOS software version with the Advanced IP Services feature set. What should the field engineer do before copying the new IOS to the router?
Set the router to load the new IOS image file directly from the TFTP server on the next reboot.
Delete the currently installed IOS by using the erase flash: command, and reload the router.
Issue the show running-configuration command to determine the features of the currently installed IOS image file.
Issue the show version and the show flash commands to ensure that the router has enough memory and file space to support the new IOS image.*
Match each OSPF LSA description with its type. (Not all options are used.)
Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.
Why are users in the OSPF network not able to access the Internet?
The default route is not redistributed correctly from router R1 by OSPF.
The interface that is connected to the ISP router is down.
The OSPF network statements are misconfigured on routers R2 and R3.
The OSPF timers that are configured on routers R1, R2, and R3 are not compatible.
The network statement is misconfigured on router R1.*
Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?

[+] has the latest features
[#] possibly is 12.4
[#] contains mostly bug fixes
Refer to the exhibit.
Which of the three Cisco IOS images shown will load into RAM?
The router selects the second Cisco IOS image because it is the smallest IOS image.
-> The router selects an image depending on the boot system command in the configuration. <-
The router selects the third Cisco IOS image because it contains the advipservicesk9 image.
The router selects the third Cisco IOS image because it is the most recent IOS image.
The router selects an image depending on the value of the configuration register.
In addition to IPBase, what are the three technology packs that are shipped within the universal Cisco IOS Software Release 15 image? (Choose three.)

Which two conditions should the network administrator verify before attempting to upgrade a Cisco IOS image using a TFTP server? (Choose two.)
Verify the name of the TFTP server using the show hosts command.
Verify that the TFTP server is running using the tftpdnld command.
Verify that the checksum for the image is valid using the show version command.
Verify connectivity between the router and TFTP server using the ping command.*
Verify that there is enough flash memory for the new Cisco IOS image using the show flash command.*
