On PE routers, the CE EBGP neighbors are configured in the VRF context D . A separate BGP process must be used on the PE routers for CE routers so that they do not use the same BGP routing process as that used for the PE router's other provider neighbor

A . by tracking the status of objects along the path to the e-commerce module B . by detecting undesirable conditions along the path to the e-commerce module C . by using the MED to communicate the site preferences for traffic to multiple ISPs D . by communicating the available prefixes， routing policies， and preferences of each site to its ISP E . by moving the SLB to a position where selected traffic to and from the servers does not go through the SLB

A . The initial log file is named message.log.prev, and a new file named message.log is started.  B . Once the log file is full, the oldest log entries are dropped to make space for new entries.  C . When the log file becomes full, it is automatically copied to an external server and a new message.log file is started.  D . Once the log file becomes full, it stops logging new messages and the new log messages are lost.

A . Allows the mirror partitions to spread across a maximum number of disks. B . Allows the copy of a partition to be on the same physical volume as the mirrored partition. C . Prevents partitions allocated to one logical volume mirror from sharing a physical volume with partitions from another logical volume mirror. D . Forces copies of logical partitions to be housed on different physical volumes, while allowing a single physical volume to be shared by logical volume mirrors.

A . EIGRP can be used only as the PE-CE routing protocol if the PE and CE routers are in the same AS B . Other EIGRP AS routes are automatically advertised to the CE router and do not require a redistribution configuration command to be configured C .

If you're ever in a bookstore or department store, it's interesting to hear how the same salesperson talks to different people. There're other interesting places to listen to conversations too. I think, and one place that I've found is on bus trips. People often talk to each other as if no one else were there. I guess they think people can't hear their conversations. Recently I was on a bus, and I was listening to a conversation of two people behind me. I can't really say I was listening. I guess it would have been hard not to hear it. it was amusing to listen to the two people, though, because they were playing a kind of language, uh, word game about states and state capitals. One person would say the name of the state, and the other person would say the name of the capital. It sounds like a kind of simple game that doesn't involve much language, and you wouldn't think that it would involve very much conversation, but actually this wasn't the case because they were playing this game. They continued to compliment one another and talk about how much they knew about history and how many of the other things that they could or couldn't remember about those places from their trips or from their reading. It was really kind of fun to listen to them. (30) A．Criticizing others on bus. B．Amusing people in pubic. C．Enjoying talking to people. D．Listening to people's in public.
