A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile cased on best practices.
Why do they have an equal split of their 120 APs across the primary and secondary gateway clusters?

  1. The primary gateway cluster is a heterogeneous cluster with six nodes.
  2. The primary and secondary gateway clusters are up. and the cluster preemption is enabled
  3. The secondary gateway cluster is a homogeneous cluster with six nodes.
  4. The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled

Answer(s): D

Explanation:

When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.



Exhibit.



A customer is reporting mat connectivity is Tailing for some wireless client Devices.
What are your conclusions from the capture? (Select two.)

  1. The client does not have an ARP entry for me default gateway.
  2. The network is using WPA2-PSK key management.
  3. The network is using WPA3-SAE key management.
  4. The client is not receiving an IP address.
  5. The client does not support beamforming.

Answer(s): B,D

Explanation:

The capture shows messages related to WPA key management, indicating WPA2-PSK is being used. Also, the capture includes a DHCP request from the client but no corresponding DHCP ACK, suggesting the client is not receiving an IP address, which could explain the connectivity failure.



Which statements accurately describe OSPF Graceful Restart (when the restarting router is able to Keep its forwarding tables across the restart)? (Select two.)

  1. The GR helper role is supported on AOX-CX 6100 switches.
  2. VSF Failover and Graceful-Restart require a VSF secondary member in the VSF stack
  3. Bidirectional Forwarding Detection for OSPF and GR are mutually exclusive features.
  4. OSPF Routers listen for Grace-LSAs on each network segment where there is an OSFP adjacency.
  5. You must ensure your VSF stack has a secondary member when acting as a GR helper

Answer(s): A,D

Explanation:

Graceful Restart (GR) allows a router to continue forwarding packets while it restarts its OSPF process. The GR helper role on AOS-CX switches supports routers during this process. OSPF routers listen for Grace-LSAs to identify neighbors undergoing a graceful restart, maintaining adjacencies with those routers to allow uninterrupted forwarding.



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

  1. SNR
  2. retry rate
  3. channel utilization
  4. number of connected clients
  5. frequency band

Answer(s): A,E

Explanation:

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.
