【正文】 問題 1 得 0 分，滿分 10 分 Which of the following OSPF mands, when used together, will put the work (Select all valid responses) 所選答案： A. Router(configrouter) work area 0 正確答案： A. Router(configrouter) work area 0 D. Router(config) router ospf 1 反饋： The work mand specifies the IP address () followed by the wildcard mask (not the sub mask), and the area that is to be associated with the OSPF address range (in this case, area 0). The wildcard mask indicates in binary how much of the IP address much be matched with 0s indicating that the bits must match and 1 indicating that they may vary. Thus or indicates that any bit in the last octet can vary while all bits in the first 3 octets must match the work address (in other words,) 問題 2 得 0 分，滿分 10 分 On the topic of the OSPF hello protocol。 which of the statements below are true? (Select two answer choices) 所選答案： A. The OSPF Hello protocol provides dynamic neighbor discovery 正確答案： A. The OSPF Hello protocol provides dynamic neighbor discovery C. The OSPF Hello protocol maintains neighbor relationships 反饋： OSPF contains a protocol (the Hello protocol) that is used to establish and maintain relationships between neighboring nodes. These relationships are called adjacencies. Adjacencies are the basis for the exchange of routing data in OSPF. 問題 3 得 0 分，滿分 10 分 Which of the following technologies can be used in distance vector routing protocols to prevent routing loops? (Select all valid answer choices) 所選答案： A. Shortest path first tree 正確答案： C. Holddown timers D. Split horizon 反饋： Distance vector routing protocols use the rule of split horizons and hold down timers to prevent routing loops after a topology change. *Splithorizon the routing protocol advertises routes out an interface only if they were not learned from updates ententering that interface. * Holddown timer After finding out that a router to a sub has failed, a router waits acertain period of time before believing any other routing information
