Exhibit.A university runs its own TV station in the city The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications in order to improve the bandwidth consumption. PlM sparse Mode and IGMP snooping features are enabled.When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way While troubleshooting the network administrator saves the packet captures shown in the exhibit and concludes that all users even those not joining the multicast group, receive the same multicast flow at slow speeds. Which features should the network administrator enable to fix the problem?
Answer(s): A
Dynamic Multicast Optimization (DMO) and Multicast Transmission Optimization are features that can help address issues with multicast traffic in wireless environments. DMO optimizes the way multicast traffic is transmitted over the air by converting multicast streams into unicast streams to the clients that need them. This reduces unnecessary traffic for clients that have not subscribed to the multicast group and can improve overall network performance. Multicast Transmission Optimization adjusts the transmission rate of multicast frames to ensure they are sent at optimal speeds, addressing the issue of multicast flow being received at slow speeds by all users.
Exhibit.Which statement is true?
Answer(s): C
The exhibit shows that the SSID supports 802.11ax clients, which is indicated by the presence of HT (High Throughput) information, VHT (Very High Throughput) capabilities, and HE (High-Efficiency) operation, which are all features associated with 802.11ax, also known as Wi-Fi 6.
A network administrator wants to configure an 802 1X supplicant for a wireless network that includes the following:1. AES encryption2. EAP-MSCHAPv2-based user and machine authentication3. 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?
Answer(s): D
When configuring an 802.1X supplicant for wireless network access with Microsoft Windows 10, enabling server certificate validation is a critical step to ensure the security of the authentication process. Server certificate validation helps prevent man-in-the-middle attacks by ensuring the RADIUS server presenting the certificate is the correct server that the client expects to communicate with.
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?
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.
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?
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.
