NEW QUESTION # 30
Which signal modulation scheme provides the highest data rate level for 802.11ax devices?
Answer: B
Explanation:
In Juniper Networks Mist AI Wireless, understanding modulation schemes is essential for designing and operating high-performance Wi-Fi 6 (802.11ax) networks. Modulation directly affects how much data can be transmitted per symbol, and therefore determines the maximum achievable data rates under optimal RF conditions.
802.11ax introduces 1024-QAM (Quadrature Amplitude Modulation) as its highest supported modulation scheme. With 1024-QAM, each symbol encodes 10 bits of data, which represents a significant increase compared to earlier standards. For reference:
* 64-QAM (used in earlier standards) carries 6 bits per symbol
* 256-QAM (introduced in 802.11ac) carries 8 bits per symbol
* 1024-QAM increases this to 10 bits per symbol
This higher bit density allows Wi-Fi 6 devices to achieve higher peak throughput, especially in environments with excellent signal quality. However, 1024-QAM requires very high Signal-to-Noise Ratio (SNR) and low interference to function reliably. As a result, it is typically achieved only when clients are close to the access point and RF conditions are clean.
Mist AI Wireless continuously monitors client RSSI, SNR, retransmissions, and modulation rates through advanced telemetry. Using this data, Mist can determine whether clients are successfully operating at higher modulation levels like 1024-QAM or are falling back to lower schemes due to RF impairments. This insight directly feeds into SLEs and AI-driven recommendations for RF tuning, AP placement, and channel planning.
The incorrect options are explained as follows:
* 64-QAM and 256-QAM are valid modulation schemes but do not provide the highest data rates in
802.11ax.
* 4096-QAM is not supported by the 802.11ax standard and is therefore invalid.
Thus, 1024-QAM is the modulation scheme that provides the highest data rate level for 802.11ax devices.
NEW QUESTION # 31
Your company received a newer model Juniper Access Point (AP) that will replace an older one.
You want to guarantee that the configuration of the older Juniper AP is transferred to the new one.
Which action will accomplish this task?
Answer: B
Explanation:
The Replace AP function is designed specifically for swapping an existing Juniper AP with a new unassigned AP while preserving the previous AP's configuration. This ensures the replacement AP inherits the old AP's assigned settings without requiring manual file transfer.
NEW QUESTION # 32
You are asked to forward event messages from Mist to an external log collector.
In this scenario, which feature would enable this capability?
Answer: D
NEW QUESTION # 33
All the access points (APs) on the site will obtain an IP address for the Management VLAN.
You notice an additional IP address for each configured VLAN on the AP.
Which statement is correct in this scenario?
Answer: C
NEW QUESTION # 34
Click the Exhibit button.
Referring to the exhibit, which two statements are true? (Choose two.)
Answer: A,C
Explanation:
The exhibit likely shows a configuration where Client Isolation (also known as Station Isolation or PSP isolation) and Broadcast Filtering (specifically ARP filtering) are enabled.
A is correct because client isolation prevents wireless devices on the same Access Point (AP) from communicating directly with each other at Layer 2. This is a common security measure in guest networks or public hotspots to prevent peer-to-peer attacks.
B is correct because modern enterprise WLAN controllers and APs often block wired-side broadcast traffic (like ARP) from being transmitted over the air to conserve wireless bandwidth and prevent "broadcast storms" on the radio frequency (RF) medium. Instead of flooding, the AP/controller often uses ARP proxying to respond on behalf of known hosts.
