bandwidth vs. clock rate?

| ok. here's one from the infamous EE5.5
quote:
The Question Was:
Choose the correct command for setting the bandwidth metric of a frame relay connection.
Correct Answer:
- router(config-if)#clock rate 56000
You use the clock rate interface configuration command to configure the clock rate for the hardware connections on serial interfaces such as network interface modules (NIMs) and interface processors to an acceptable bit rate. Setting the clock rate is the same regardless of whether it is for frame relay or an alternative.
Example:
The following example sets the clock rate on the first serial interface to 64,000 bits per second:
interface serial 0
clock rate 64000
Page ReferenceL 32, CCNA Jump Start: Networking and Internetworking Basics (Network Press, Sybex, Inc.)
of the options presented i chose one that was something like: router(config)#bandwidth 56 even though i knew it had to be done on the interface or more like: router(config-if)#bandwidth 56
what i am getting to is, are the EE people wrong here? i mean, the question asks to configure the bandwidth, not the clock rate (where they would be right). and the clock rate is only when using the router as a DCE in a lab environment without a DSU (according to Lammle's CCNA study guide - pp. 202 - 203). right? so, if i want to configure my bandwidth metric (which will be used by my routing protocol, regardless of the type of connection), do i not use the following:
router(config)#int s0 --> bandwidth 56
please. tell me i am right on this one. even though there wasn't an answer for this option exactly, based on how the question was worded, would anyone else agree with me?
thanx.
addendum:
here are the actual options from the question:
router(config)#frame 56000
router(config)#frame relay bandwidth 56000
router(config-if)#clock rate 56000
router(config)#frame clock 56000
router(config)#clock rate 56
router(config)#clockrate 56
router(config)#clock rate 56 <-- yes, listed 2x
router(config)#bandwidth 56
router(config)#bandwidth 56000 <-- the one i chose but it needs to be in the Int. Conf.
router(config)#serial 0 clockrate 56 | |

| Clockrate is set on the DCE (frame switch) and BW is set on the DTE (your end).
Clockrate is in bits (64000)
Bandwidth is in KB (64) | |

| Despite you beeing "completly insane" you know this better than whoever made up that practice question.
