以下关于RIP,叙述正确的是( ) A: RIP称为“路由信息协议” B: RIP是距离向量协议,其路由项中包括目的地址、下一跳路由器地址和跳数(Hops) C: 为了实现路由信息的可靠传输,RIP采用TCP传输数据 D: RIP v2通过版本升级,解决了无穷计数问题(好消息传的快,坏消息传的慢) E: RIP是小型路由协议,不支持超过16个路由器的自治系统内的路由

DHCP报文有很多种类型，关于DHCP报文的封装的描述正确的（）。 A: DHCP报文中包含RelayAgentIPAddress字段，表示DHCPRelay的IP地址，如果到达DHCP服务器前经过了不止一个DHCPRelay，那么后续的DHCPRelay中继也会改变此字段 B: DHCP报文中Hops字段表示的是DHCP报文经过的DHCPRelay的数目，每经过一个DHCPRelay时，该字段加1 C: Options字段表示DHCP的选项字段，至少为512字节 D: DHCP通过Options字段包含了服务器分配给终端的配置信息，如网关IP地址，DNS服务器的IP地址，客户端可以使用IP地址的有效租期等信息

The method for making beer has changed over time. Hops （啤酒花）, for example, which give many a modern beer its bitter flavor, are a __26__ recent addition to the beverage. This was first mentioned in reference to brewing in the ninth century. Now, researchers have found a __27__ ingredient in residue （残留物）from 5000-year-old beer brewing equipment. While digging two pits at a site in the central plains of China, scientists discovered fragments from pots and vessels. The different shapes of the containers __28__ they were used to brew, filter，and store beer. They may be ancient "beer-making tools," and the earliest __29__ evidence of beer brewing in China, the researchers reported in the Proceedings of the National Academy of Sciences. To __30__ that theory, the team examined the yellowish, dried __31__ inside the vessels. The majority of the grains, about 80%, were from cereal crops like barley （大麦）, and about 10% were bits of roots, __32__ lily, which would have made the beer sweeter, the scientists say. Barley was an unexpected find; the crop was domesticated in Western Eurasia and didn’t become a __33__ food in central China until about 2,000 years ago, according to the researchers. Based on that timing, they indicate barley may have __34__ in the region not as food, but as __35__ material for beer brewing. A) arrived B) consuming C) direct D) exclusively E) including F) inform G) raw H) reached I) relatively J) remains K) resources L) staple M) suggest N) surprising O) test
