An ACME company employee complained about a recent poor-quality VoIP call while moving around their office environment HPE Aruba Networking Central reported a fair UCC score for this call while your VoIP engineer reported that their systems reported a MOS of 2, 3. The VoIP devices are operating over the 5GHz frequency band.
What are the possible contributing factors? (Select two.)

  1. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
  2. 802.tr is enabled in the WLAN Security settings.
  3. There was localized interference at the caller's location
  4. 802.1K is disabled in the WLAN Security settings
  5. The client roamed into an area that continuously operates Zigbee.

Answer(s): A,E

Explanation:

VoIP quality can be negatively impacted by insufficient cell overlap in AP deployment plans, which can cause poor handoffs between APs as a user moves around. This results in a degraded VoIP experience. Additionally, roaming into an area with continuous Zigbee operation can cause interference with the 5GHz frequency band, further contributing to poor VoIP call quality. The Zigbee communication protocol operates on the same frequency band as Wi-Fi and can introduce noise and interference, which leads to a reduced MOS score, as reported by the VoIP engineer.



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?

  1. Disable 802 11r.
  2. Disable 802 11k.
  3. increase 5Gnz TX power range Min/Max.
  4. increase 5 GHz wireless coverage tuning to Aggressive.

Answer(s): C

Explanation:

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.



Refer to the CLI output below:



What statement about the output above is correct?

  1. The port-access role was configured with gateway-role visitor
  2. The secondary tunnel endpoint IP is 10.10-10.151.
  3. The client authenticated using dot1x.
  4. The UBT zone was configured to use a user-defined VRF

Answer(s): B

Explanation:

The CLI output indicates a tunnel creation process, where "SW hw tun created" refers to the switch hardware tunnel being created. The line mentioning "BYP-10.10.10.101 -> SW hw tun created to 10.10.10.151 tunnel 15." implies that a tunnel was established to the secondary tunnel endpoint with the IP address 10.10.10.151. This is a common configuration for User-Based Tunneling (UBT) setups where traffic is tunneled to a specific endpoint.



Which statement is true given the following CLI output from a CX 6300?

  1. The underlay loopback addresses are in the 172 21 11 x range.
  2. There are two anycast addresses m me overlay fabric.
  3. Duplicate MAC addresses were detected in the overlay fabric
  4. There are three active client overlay VLANs in the overlay fabric

Answer(s): A

Explanation:

The CLI output displays EVPN routes and their corresponding next hops. The "Route Distinguisher" entries followed by IP addresses in the 172.21.11.x range indicate these are loopback addresses used by the underlay network. The underlay network provides the basic routing and forwarding plane for the overlay network that EVPN is part of. These loopback addresses are crucial for the proper functioning of the EVPN control plane.
