Question

Examine the ArubaOS-CX switch configuration:

switch (config) #access-list ip external
switch (config-acl-ip) #permit ip any 10.0.253.0/255.0.255.0 count
switch (config-acl-ip) #permit ip any 10.0.254.0/255.0.255.0 log 
switch (config-acl-ip) #exit 
switch (config) #interface 1/1/1 
switch (config-if) #apply access-list ip external in 
switch (config-if) #exit

Which statement correctly describes what is allowed for traffic entering interface 1/1/1?

A. IP traffic from 10.11.253.1 is allowed to access 10.10.254.10
B. IP traffic from 10.11.253.1 is allowed to access 10.1.252.0/24
C. Traffic from 10.0.253.0/24 will increment the counters when accessing 10.0.254.0/24
D. IP traffic from 10.10.254.1 is allowed to access 192.168.254.0/24

Answer

C. Traffic from 10.0.253.0/24 will increment the counters when accessing 10.0.254.0/24

Explanation

The access control list (ACL) named “external” is applied to interface 1/1/1 in the inbound direction. This ACL contains two permit statements:

  1. The first permit statement allows IP traffic from any source to the destination network 10.0.253.0/255.0.255.0 (effectively 10.0.253.0/24) and enables counting for this traffic.
  2. The second permit statement allows IP traffic from any source to the destination network 10.0.254.0/255.0.255.0 (effectively 10.0.254.0/24) and enables logging for this traffic.

Option A is incorrect because the ACL does not specify allowing traffic from 10.11.253.1 to 10.10.254.10 specifically. The ACL allows traffic from any source to the 10.0.253.0/24 and 10.0.254.0/24 networks.

Option B is incorrect for the same reason as option A. The ACL does not allow traffic specifically from 10.11.253.1 to 10.1.252.0/24.

Option C is correct because the first permit statement in the ACL allows traffic from any source (including 10.0.253.0/24) to the 10.0.253.0/24 network and enables counting for this traffic. When a host from the 10.0.253.0/24 network sends traffic to the 10.0.254.0/24 network, the counter will be incremented.

Option D is incorrect because the ACL does not specify allowing traffic from 10.10.254.1 to 192.168.254.0/24. The ACL only allows traffic to the 10.0.253.0/24 and 10.0.254.0/24 networks.
