C. Besides the regular LFA backup paths, this command also installs the remote LFA backup paths.
D. All backup routes ?not only the best backup route are installed in the OSPF RIB.
Answer: D
Explanation:
http://www.cisco.com/c/en/us/td/docs/ios- xml/ios/iproute_ospf/configuration/xe-3s/iro-lfa-frr-xe.pdf Candidate Repair-Path Lists When OSPF computes a repair path, it keeps in the local RIB only the best from among all the candidate paths, in order to conserve memory. You can use the fast-reroute keep-all-paths command to create a list of all the candidate repair paths that were considered. This information can be useful for troubleshooting but it can greatly increase memory consumption so it should be reserved for testing and debugging.
