Exam 300-710 topic 1 question 88 discussion

B. to represent protocols other than TCP, UDP, and ICMP This functionality allows port objects in Cisco FMC to include a wide range of additional protocols, providing flexibility in defining access control rules.

B to represent other protocols. In the FMC GUI, when you create a port object, the Protocol field allows: TCP, UDP, ICMP, IPv6-ICMP, OTHER. When you choose other, a drop down box becomes enabled, with 50+ additional protocols, none of which I recognized.

According to the documentation, the answer is correct. Ans.B "A port object can represent other protocols that do not use ports." And the other options are casually mentioned in the documentation as being wrong. A and D: # When using port objects, observe the following guidelines: -"You cannot add any protocol other than TCP or UDP for source port conditions in access control rules. Also, you cannot mix transport protocols when setting both source and destination port conditions in a rule." -"If you create a port object containing both TCP and UDP ports, then add it as a source port condition in a rule, you cannot add a destination port, and vice versa." # and answer C: #Port objects represent different protocols in slightly different ways: *and start with the introduction* https://www.cisco.com/c/en/us/td/docs/security/firepower/630/configuration/guide/fpmc-config-guide-v63/reusable_objects.html#ID-2243-00000364

Very vague question. B - doesn't fit at all cos TCP/UDP/ICMP already exist as default objects. So what does "other than" mean? Except? C - fits better.
