Exam : Cisco 350-021
Title : CCIE SP Cable Qualification Exam


1. A router is set to boot from flash, but cannot find boot commands in the configuration. Also, valid files do not exist in the default flash device. The router will:
A. Boot from ROM, since there are no valid sources
B. Try to boot from the network, using a default filename
C. Terminate the boot process with an error message
D. Try to boot from the network, then boot from ROM as a backup
Answer: D

2. If there are two different headends with two different frequencies available sharing the same plant, what frequency will the two groups of cable modems, which are brand new, and have never been on-line, lock on?
A. They will lock on the frequency configured on the linecard.
B. They will lock on the frequency configured on the upconverter.
C. They will lock on the first frequency they find.
D. They will lock on the lowest frequency.
E. They will lock on the last frequency remembered in ram.
Answer: C

3. Which are HFC cable television forward path networks aligned to provide? (multiple answer)
A. For asymmetrical gain since the downstream and upstream bandwidths are also asymmetrical
B. For unity gain with a fixed input level and varying output levels adjusted by the selection of a fixed value attenuator and equalizer at the output stage in each of the forward amplifiers in the network
C. For unity gain with a fixed output level and varying input levels adjusted by the selection of a fixed value attenuator & equalizer at the input stage of each of the forward amplifiers in the network
D. It is not necessary to align the forward path amplifiers since the CMTS will automatically compensate for forward path gain discrepancies.
E. For unity gain and are level compensated by automatic gain and slope control systems utilizing RF pilot reference carriers
Answer: CE

4. A network administrator is using debug commands to check the performance of a network. What steps can the administrator take to ensure that the "debug" will not require too much CPU, or at least that she will not have to reboot the router to disable debug? (multiple answer)
A. Make the debug command as specific as possible
B. Use the max-time parameter of the debug command
C. In configuration mode, enter scheduler interval 15
D. Configure a loopback to channel debug traffic
Answer: AC

5. HFC cable television return path networks are aligned to provide: (multiple answer)
A. Asymmetrical gain since the downstream and upstream bandwidths are also asymmetrical
B. Unity gain with a fixed input level and varying output levels adjusted by the selection of a fixed value attenuator and equalizer at the output stage in each of the return amplifiers in the network
C. Unity gain with a fixed output level and varying input levels adjusted by the selection of a fixed value attenuator and equalizer at the input stage of each of the return amplifiers in the network
D. Cable modems the ability to power range comfortably within their output power dynamic range
E. It is not necessary to align the return path amplifiers since the CMTS will automatically adjust the cable modem transmit power levels.
