Which attribute eliminates LFAs that belong to protected paths in situations where links in a network are connected through a common fiber?
Which attribute eliminates LFAs that belong to protected paths in situations where links in a network are connected through a common fiber?
The attribute that eliminates LFAs (Loop-Free Alternates) which belong to protected paths when links in a network are connected through a common fiber is 'shared risk link group-disjoint'. SRLGs (Shared Risk Link Groups) are groups of links that share a common physical resource, such as a fiber. If one link in an SRLG fails, the other links in that group may also fail due to the shared risk. Therefore, eliminating LFAs that belong to any of the protected path SRLGs is crucial to ensure network resilience.
A seems to be right, https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_eigrp/configuration/xe-3s/asr1000/ire-xe-3s-asr1000/ire-ipfrr.html#:~:text=Shared%20Risk%20Link,group%20share%20risks.
A is correct - Shared Risk Link Group (SRLG)-disjoint—Eliminates LFAs that belong to any of the protected path SRLGs. SRLGs refer to situations where links in a network share a common fiber (or a common physical attribute). If one link fails, other links in the group may also fail. Therefore, links in a group share risks.
appeared in my exam, along with several DNA questions that really shouldn't be here!
Has this question appeared in anyone's exam?

I agree that A is true
should be A correct
A is the correct answer

it´s A
Seems A to be the correct one. Shared Risk Link Group-disjoint: Eliminates LFAs that belong to any of the protected path Shared Risk Link Groups (SRLGs). SRLGs refer to situations where links in a network share a common fiber (or a common physical attribute). If one link fails, other links in the group may also fail. Therefore, links in a group share risks. \https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9500/software/release/1configuration_guide/rtng/b_175_rtng_9500_cg/configuring_eigrp_loop_free_alternate_ip_fast_reroute.html
