• Question 2:

  An OSPF router has learned a pain 10 an external network by Doth an E1 and an E2 advertisement Both routes have the same path cost Which path will the router prefer?

  A. The router will prefer the E1 path.
  B. The router will use Doth paths equally utilizing ECMP.
  C. The router will prefer the E2 path.
  D. Both routes will be suppressed until the path conflict has been resolved.
  A. The router will prefer the E1 path.

  ---

  explanation:

  Explanation/Reference:

  In OSPF, when a router learns about an external network through both E1 and E2 advertisements, and if both have the same path cost, the router will prefer the E1 path. This is because E1 routes consider both the external cost to reach the external network and the internal cost to reach the ASBR, providing a more comprehensive metric. E2 routes only consider the external cost and ignore the internal cost to the ASBR, which could potentially lead to suboptimal routing. Therefore, the router will choose the E1 path due to its more accurate representation of the total path cost.

• Question 3:

  Which option shows the correct Banawidth Control for 1024 kbpsdown and 2048 Kops up for the SSID?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

  ---

  explanation:

  Explanation/Reference:

  The correct Bandwidth Control settings for 1024 Kbps down and 2048 Kbps up for the SSID are shown in Option D. In Option D, the downstream is set at 1024 Kbps and the upstream at 2048 Kbps, both configured per user, which matches the requested configuration. This setup ensures that each user has a guaranteed bandwidth allocation of the specified rates when connected to the SSID, providing a controlled and predictable user experience.

• Question 4:

  A customer is planning to add loT devices that connect wirelessly to the existing 802.1X SSlD. The customer will use ClearPass to authenticate the IoT devices by MAC address but other devices will still need to authenticate by only 802 1X Exhibit.

  

  The customer provided the current configuration and reported their non-loT 802. IX devices are no longer able to connect. Which configuration change can be made to fix the issue?

  B. Modify opmode wpa3-aes-gcm-256 to opmode wpa2-aes
  C. Add i2-autn-fairtnrougn to the WLAN configuration
  D. Remove mac-authentication from the WLAN configuration
  E. Modify max-authentication failures to 0.
  C. Add i2-autn-fairtnrougn to the WLAN configuration

  ---

  explanation:

  Explanation/Reference:

  The existing configuration for the WLAN ssid-profile has enabled MAC authentication which, while suitable for IoT devices that may not support 802.1X, can interfere with the normal 802.1X authentication process for other devices. By removing the mac-authentication directive from the WLAN configuration, the non-IoT 802.1X devices should be able to connect without issues as the authentication process will not be disrupted by MAC authentication checks. This adjustment ensures that the WLAN ssid-profile is correctly aligned with the authentication requirements for both IoT and non-IoT devices within the network environment, conforming to the best practices for mixed-device WLAN configurations.

• Question 5:

  The wireless administrator for a college campus is gelling reports of connectivity issues when students are working outdoors. Reviewing the settings above, watch change is needed to align with best practices?

  A. Disable 802 11r.
  B. Disable 802 11k.
  C. increase 5Gnz TX power range Min/Max.
  D. increase 5 GHz wireless coverage tuning to Aggressive.
  C. increase 5Gnz TX power range Min/Max.

  ---

  explanation:

  Explanation/Reference:

  To address connectivity issues when students are working outdoors, increasing the transmission (TX) power range for the 5GHz radios can help improve signal strength and coverage. The setting shown indicates a conservative approach to power settings, which might not provide sufficient coverage for outdoor areas. By increasing the power range, you can extend the wireless signal reach, which aligns with best practices for outdoor wireless coverage.

• Question 6:

  A network administrator wants to configure an 802 1X supplicant for a wireless network that includes the following:

  1.

  AES encryption

  2.

  EAP-MSCHAPv2-based user and machine authentication

  3.

  validation of server certificate in Microsoft Windows 10

  The network administrator creates a WLAN profile and selects the change connection settings option Then the network administrator changes the security type to Microsoft Protected EAP (PEAP) and enables user and machine authentication

  under Additional Settings.

  What must the network administrator do next to accomplish the task?

  A. Enable user authentication
  B. Change the security type to Microsoft: Smart Card or other certificate.
  C. Change default RC4 encryption for AES
  D. Enable server certificate validation
  A. Enable user authentication
  D. Enable server certificate validation

• Question 7:

  You are troubleshooting a WLAN deployment with APs and gateways set up with an 802.1X tunneled SSIO. End-users are complaining that they can't connect to die enterprise SSID. Which possible AP tunnel states could be the cause of the Issue? (Select two.)

  A. SM_STATE_RE KEYING
  B. SM_STATE_SURVIVED
  C. SM_STATE_CONNECTED
  D. SM_STATE_SURVIVING
  E. SM_STATE_CONNECTING
  A. SM_STATE_RE KEYING
  E. SM_STATE_CONNECTING

  ---

  explanation:

  Explanation/Reference:

  When troubleshooting a WLAN with 802.1X tunneled SSID issues, AP tunnel states indicate the status of the connection between the AP and the gateway/controller. The states 'SM_STATE_REKEYING' and 'SM_STATE_CONNECTING' could indicate transitional states where the connection has not been fully established, hence users might face issues connecting to the SSID. 'SM_STATE_REKEYING' implies that the AP is in the process of re-establishing encryption keys, while 'SM_STATE_CONNECTING' indicates that the AP is trying to establish a connection with the controller or gateway. These states could lead to temporary connectivity issues until the state transitions to 'SM_STATE_CONNECTED'.

• Question 8:

  A customer has recently deployed a wireless system using AP-535S to provide connectivity for their employees who are responsible tor uploading large video files for review. The customer wants to use features that provide throughput gains for large data uploads.

  Which feature can be enabled to meet the requirement and simultaneously allow spatially separated clients access to the channel?

  A. Ul-TXBF
  B. OFOMA
  C. DL MU-MIMO
  D. UL MU-MIMO
  D. UL MU-MIMO

  ---

  explanation:

  Explanation/Reference:

  UL MU-MIMO, or Uplink Multi-User Multiple Input Multiple Output, is a technology that allows multiple clients to transmit data to the access point simultaneously, increasing overall throughput and efficiency, especially for upload-heavy scenarios like video file uploads. This technology enables spatially separated clients to access the channel at the same time, which can improve performance for clients when uploading large files.

• Question 9:

  A customer has deployed anAOS 10 mobilitygateway cluster consisting of three controllers at a single site The WLAN is configured to tunnel wireless device traffic to the AOS 10 mobilitycluster.The clients areauthorized to use WPA2Personal.An end-userhas opened a ticket with the helpdesk stating they cannot connect their client device to the network.There are other devices currently associated with the SSID with no issues.

  

  Reviewing the output, what Is the issue?

  A. The RADIUS response from the authentication server is
  B. The client device has an invalid certificate
  C. The client device has an invalid pre-shared key.
  D. transition mode is not enabled
  C. The client device has an invalid pre-shared key.

  ---

  explanation:

  Explanation/Reference:

  The issue indicated by the output is an invalid pre-shared key (PSK). The logs show multiple failures during the WPA2 key exchange process, which points to a mismatch between the PSK configured on the client device and the PSK expected by the AOS 10 mobility gateway.

• Question 10:

  Exhibit.

  

  What is me expected behavior for ARP traffic sent from H1?

  A. A2 will drop the ARP traffic.
  B. A2 will send the ARP traffic out of ports 1/1/1-1/1/4.
  C. A2 willflood the ARP traffic out of all interfaces.
  D. A2 willsend the ARP traffic out of ports 1/1/1 and 1/1/3.
  C. A2 willflood the ARP traffic out of all interfaces.

  ---

  explanation:

  Explanation/Reference:

  In a VXLAN environment, unknown unicast traffic, such as ARP requests from H1, which does not have a specific destination MAC address learned by the switch A2, will be flooded out of all interfaces. This flooding behavior is necessary because A2 needs to ensure that the ARP requestreaches its intended destination, which might be on any of the interfaces. It's a part of the standard behavior of switches to handle ARP traffic when the destination hardware address is unknown.
