Question 1

Explanation

ACLs on the Cisco Wireless LAN Controller (WLC) are meant to restrict or permit wireless clients to services on its WLAN. With WLC we can verify the ACLs on the ACL web page and verify that your ACL changes were applied to the controller’s interface.

    Can’t Cisco APIC-EM verify ACL’s?

    I’m with MikeJS. Note: Then there’s also section 4.5, “Verify ACLs using the APIC-EM Path Trace ACL analysis tool.” That sounds straightforward enough if you can get your hands on the tool, but is not going to fail you by itself if it’s the only thing you don’t know.

    WLC’s have nothing to do with tracing ACL’s. WLC’s are used as centralized management systems for LWAPP/CAPWAP access points (as opposed to autonomously configured AP’s).

    From another site:”APIC-EM implements ACL Path Trace which is a special app developed to determine the impact of ACLs in the Network.” I’m with Fred ^

    9tut can you explain more about this question?It looks Cisco APIC-EM is the correct one

    I’m glad I’m not the only one wondering this. I’m going to try to find an answer to this question, bc this guy is not helpful.

    So I believe when it asks for platform that means the device specifically. APIC-EM is an application, not a platform. Wireless LAN Controllers have APIC-EM loaded on them and they use it to verify ACLs. That’s just my guess. I found a lot of people that argue that the answer is APIC-EM. This question is too confusing.

    The answer is correct. You can create, verify, test and apply ACL on WLAN Controllers interfaces.

    APIC-EM ACL Analysis

    One of the most important features of the APIC-EM controller is the ability to manage policies across the entire network. Policies operate at a higher level of abstraction. Traditional device configuration applies to one device at a time, whereas SDN policies apply to the entire network.

    APIC-EM ACL Analysis and Path Trace provide tools to allow the administrator to analyze and understand ACL policies and configurations. Creating new ACLs or editing existing ACLs across a network to implement a new security policy can be challenging. Administrators are hesitant of changing ACLs for fear of breaking them and causing new problems. ACL Analysis and Path Trace allows the administrator to easily visualize traffic flows and discover any conflicting, duplicate, or shadowed ACL entries.

    APIC-EM provides the following tools to troubleshoot ACL entries:
    ACL Analysis

    This tool examines ACLs on devices, searching for redundant, conflicting, or shadowed entries. ACL Analysis enables ACL inspection and interrogation across the entire network, exposing any problems and conflicts. An example screenshot of this tool is shown in Figure 1.

    ACL Path Trace

    This tool examines specific ACLs on the path between two end nodes, displaying any potential issues. An example screenshot of this tool is shown in Figure 2.

    For the objectives covered by the CCNA certification in your Networking Academy curriculum as well as the official study material, cisco refers to the APIC-EM platform as a tool / platform for verifying ACL.
    There is no mention of “Wireless Controller LAN”.

    The answer is C please correct your website. This isn’t the first error I notice.
