下面是cisco网站关于tftp-server system filename list的解释：
Configuring the Trivial File Transfer Protocol (TFTP) Server
You can configure the network server to act as a limited Trivial File Transfer Protocol (TFTP) server from which other Cisco servers can boot their software. As a TFTP server host, the network server responds to TFTP read request messages by sending a copy of its ROM software to the requesting host. The TFTP read request message must use the file name that you specified in the network server configuration.

To specify TFTP server operation for a communications server, use the tftp-server system global configuration command. The full syntax follows.

tftp-server system filename list
no tftp-server system filename list
This command has two arguments: filename and list. The argument filename is the name you give the communications server ROM file, and the argument list is an IP access-list number.

The system sends a copy of the ROM software to any host which issues a TFTP read request with this file name. To learn how to specify an access list, see the "Configuring IP Access Lists" section in the chapter "Routing IP."

You can specify multiple file names by repeating the tftp-server system command. To remove a previously defined file name, use the no tftp-server system command and append the appropriate file name and an access-list number.

Images that run from ROM, including IGS images, cannot be loaded over the network. Therefore, it does not make sense to use TFTP to offer the ROMs on these images.

Example:
This command causes the router to send, via TFTP, a copy of the ROM software when it receives a TFTP read request for the file configfile. The requesting host is checked against access list 22.

tftp-server system configfile 22

21．You are configuring a new catalyst switch that you want to manage remotely from workstations on other network segment within your enterprise. Which of the following are required to allow remote management of the switch over IP? (Choose two.)
A. The Frame Relay encapsulation on the physical interface.
B. The local DLCI on each subinterface.
C. An IP address on the physical interface.
D. The subinterface type as point-to-point
Answer: C
管理的是个交换机，交换机的IP是为了管理，在子借口上不能设地址。

请问第二个选择是 A 对么？

D. If the "no console logging" command were configured, output would be sent to a telnet session.
E. All of the above.

2

21.A有问题，我不用encap frame也是可以的，只要设ip地址就行了，可以通过e0来访问交换机，更何况fr是用在s口上的，交换机根本就没s口（至少我没见过）。
1.E，AB肯定正确，书上有。CD不清楚。
2.C，sybex书上讲routing里面就有，自己找。
3.B隧道技术。
4.AB，基本的交换机知识了。
5.ABD
6.C


PS：如果对上面的争议题有问题，请回复在这边。不然请另发一帖子，问问题不要在这个帖子下问，这样显得很乱。

13.  Q.333＝Q308   更正的答案选C  让我们看看新的解释。
Which of the following is true concerning FrameRelay multipoint subinterfaces?
A. An IP address is required on the physical interface of the central router.
B. All routers are required to be fully meshed.
C. All routers must be in the same subnet to forward routing updates and broadcasts.
D. Multipoint is the default configuration for Frame Relay subinterfaces.
Answer: D
Explanation: Cisco serial interfaces are multipoint interfaces by default unless specified as a point-to-point
subinterface.
Incorrect Answers
A: An IP address is required for each subinterface. An IP address is not required for the physical interface.
B: Routers are not required to be fully meshed.
C: Routers do not have to be in the same subnet.
