問題文
An operator writes the hashing that reads the source address alone on the way in and the destination address alone on the way out, and has to place each half of it in the right part of the configuration. Where does the length of the address that feeds the hash belong, and may the inbound choice and the outbound choice sit in one term?
選択肢
- The length and the choice between the source and the destination both belong inside the policy term, and one term takes both choices at once, so a single term covers each direction over the same route filter
- The length belongs to a forwarding option that holds for the whole device while the choice between the source and the destination is an action inside a policy, and one term takes both choices at once, so a single term covers each direction over the same route filter
- The length and the choice between the source and the destination both belong inside the policy term, and the one choice bars the other from that term, so a term of its own is written for each direction over the same route filter
- The length belongs to a forwarding option that holds for the whole device while the choice between the source and the destination is an action inside a policy, and the one choice bars the other from that term, so a term of its own is written for each direction over the same route filter
