CCNA Routing and Switching (legacy) — Question 87

A network administrator is configuring ACLs on a Cisco router, to allow IP access from the 192.168.146.0/24, 192.168.147.0/24, 192.168.148.0/2,. and
192.168.149.0/24 networks only. Which two ACLs, when combined, should be used?

Answer options

• A. access-list 10 permit ip 192.168.146.0 0.0.0.255
• B. access-list 10 permit ip 192.168.146.0 255 255.255.0
• C. access-list 10 permit ip 192.168.147.0 0.0.255 255
• D. access-list 10 permit ip 192.168.149.0 0.0.255.255.0
• E. access-list 10 permit ip 192.168.148.0 0.0.1.255
• F. access-list 10 permit ip 192.168.146.0 0.0.1.255

Correct answer: E, F

Explanation

The correct answer is E and F because they accurately permit access for the specified networks. Option E allows access for 192.168.148.0 with the correct wildcard mask, while option F incorrectly uses a wildcard mask that does not properly match the intended 192.168.146.0/24 network. Other options either permit incorrect ranges or use incorrect wildcard masks.
