• Question 11:

  A BGP routing tablecontains multiple routes to the same destination prefix.

  Referring to the table below whichroutewould be marked with a ">" symbol?

  

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

  ---

  Explanation/Reference:

  In BGP, the route marked with a ">" symbol is the best route that is chosen based on BGP attributes in the following order: highest weight (Cisco-specific), highest local preference, originated by BGP running on the local router, shortest AS path, lowest origin type, lowest MED, eBGP over iBGP, closest IGP neighbor, and lowest BGP router ID. Based on the table provided, Option E would be marked with a ">" symbol as it has the highest local preference of 100 which is a decisive factor in the BGP best path selection process.

• Question 12:

  A network administrator attempts to improve multicast traffic flow and performs some packet captures for validation What can the network administrator conclude from the results?

  A. The data rate increased from 6 Mops to 300 Mops because Broadcast Multicast optimization (BCMCO) was configured.
  B. The capture taken after optimization does not show a packet length because Multicast Transmission Optimization was configured.
  C. The type flew remains consistent because Dynamic Multicast Optimization (DMO) was configured.
  D. The data rate increased from 6 Mbps to 300 Mops because Dynamic Multicast Optimization (DMO) was configured.
  D. The data rate increased from 6 Mbps to 300 Mops because Dynamic Multicast Optimization (DMO) was configured.

  ---

  Explanation/Reference:

  Dynamic Multicast Optimization (DMO) is a feature that enhances the delivery of multicast traffic by optimizing the data rate. The before and after optimization images show a significant increase in the data rate, which is a typical result of DMO being configured, as it allows multicast traffic to be transmitted at higher data rates by converting multicast streams into unicast streams for the clients that need them.

• Question 13:

  What directly affects the MCS used by wireless stations? (Select two.)

  A. SNR
  B. retry rate
  C. channel utilization
  D. number of connected clients
  E. frequency band
  A. SNR
  E. frequency band

  ---

  Explanation/Reference:

  The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal-to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.

• Question 14:

  A customer is evaluating device profiles on a CX 6300 switch. The test device has the following attribute:

  

  MAC address=81:cd:93:13:ab:31

  The test device needs to be assigned the "lot-prod'' role, in addition the "lot-default" role must be applied for any other device connected lo interface 1/1/1. This is a lab environment with no configuration of any external authentication server for

  the test.

  Given the configuration example, what is required to meet this testing requirement?

  A. Enter the command "pot-access device-profile mode block-until-profile-applied"" for interface 1/1/1.
  B. Enter the command "port-access fallback-role lot-default globally
  C. Enter the command "port-access onboarding-method precedence" to set device profiles with a lower precedence.
  D. Enter the command "port-access device-profile mode block-until-profile-applied" globally.
  A. Enter the command "pot-access device-profile mode block-until-profile-applied"" for interface 1/1/1.
  B. Enter the command "port-access fallback-role lot-default globally
  C. Enter the command "port-access onboarding-method precedence" to set device profiles with a lower precedence.

• Question 15:

  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/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.

• Question 16:

  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/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 17:

  A deployment using AP-635S is connectedto a stack of CX 6300s as shown.

  

  The output of the snow LACPinterfaces shews the following:

  

  What is causing this issue?

  A. e0 is connected to a smart rate interface, and e1 is connected to a non-smart rate interface.
  B. Spanning tree and loop protect are enabled on both AP uplink ports.
  C. Each AP interface is connected to a routed-only interlace on different networks
  D. The AP is configured with LACP active
  D. The AP is configured with LACP active

  ---

  Explanation/Reference:

  In an Aruba deployment, if an AP's interfaces show different LACP states, it often indicates a configuration mismatch. If one interface is up and the other is blocked as shown in the output,it's likely due to both interfaces on the AP being set to LACP active mode, which is a correct setting for establishing an LACP channel with Aruba switches like the CX 6300 series.

• Question 18:

  Exhibit.

  

  Which would explain this issue?

  A. HTTPS wildcard certificates are not supported
  B. HTTPS certificate is not required in ClearPass Guest.
  C. captiveportal-login aruba-training com needs to be entered m the Address field for the ClearPass Guest
  D. ".aruba-training com needs to be entered in the Address field for the ClearPass Guest
  D. ".aruba-training com needs to be entered in the Address field for the ClearPass Guest

  ---

  Explanation/Reference:

  The correct address for the ClearPass Guest should match the FQDN of the HTTPS certificate installed on the device, which is often the FQDN of the vendor's product. This ensures secureand proper redirection to the captive portal during the authentication process. The FQDN should be entered in the Address field for ClearPass Guest configuration.

• Question 19:

  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/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 20:

  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/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.
