Exam 200-301 topic 1 question 658 discussion

A is correct, standard is 1-99 or 1300-1999

It's A, but I argue that the syntax on the same line of permit & deny is somewhat confusing...

its in the NAME ip access-list standard 99 good ip access-list standard 199 wrong they got me :)

A is correct

Technically D is also correct because the ACLs are typed in named notation, any number works

key word is "from" a standard access list only focus on source and it ranges from 1 - 99

I am putting a review at the end of the exam to complain about the answer's format if they are laid out this way. it has become an exam to confuse you not to test your technical abilities.

Options ‘b’ and ‘c’ have W/C masks of 0.255.255.255 which are wrong for 192.168.0.0 /16. Options ‘a’ and ‘d’ start with the command “ip”, so they are named ACLs. The number (99 vs. 199) has no bearing on the veracity of the ACL as it is treated as a name. Technically, options ‘a’ and ‘d’ should both work just fine. Regardless, let’s keep it “nice” and use a standard ACL number (99). For this reason, I’d pick option ‘a’.

Standard ACLs: Standard ACLs are used to filter traffic based on the source IP address only. They are identified by numbers from 1 to 99 and 1300 to 1999. Extended ACLs: Extended ACLs allow filtering based on various criteria such as source and destination IP addresses, TCP/UDP ports, protocols, etc. They are identified by numbers from 100 to 199 and 2000 to 2699.

A. ip access-list standard 99 permit 10.100.100.0 0.0.0.255 deny 192.168.0.0 0.0.255.255 0.0.0.255 = /24 0.0.255.255 = /16

Answer is A

Because of the /16

It is not choice D because for Standard Access Control Lists, Access list number must be between 1–99 or 1300–1999. Choice D's access list number was not within this range. https://www.omnisecu.com/cisco-certified-network-associate-ccna/standard-access-control-lists.php#:~:text=Standard%20Access%20Control%20Lists%20(ACLs)%20are%20the%20oldest%20type%20of,access%2Dlists%22%20IOS%20command.
