   A user in a warehouse reports that their handheld scanner intermittently loses connectivity while moving along a specific aisle. Client-level SLE shows 'Roaming' failures at that location. RF Insights shows no interference or coverage gaps. The packet capture for the client shows repeated 802.11 authentication requests to the same AP without a response. What is the MOST likely root cause and the next step to confirm it?

   • AThe AP is rebooting due to a power issue; check the AP's uptime and PoE status in the Mist UI
   • BThe client's 802.1X credentials are failing; check the RADIUS server logs for authentication rejections
   • CThe client is stuck in a fast-roaming loop; check the AP's PMKID cache settings and the client's 802.11r configuration
   • DThe aisle has a hidden coverage gap; run a new site survey to verify RF coverage

   What is a Service Level Expectation (SLE) metric in Juniper Mist?

   • AA contractual agreement between the customer and Juniper for network uptime
   • BA security policy that enforces encryption standards on the WLAN
   • CA configuration setting that defines the maximum number of clients per AP
   • DA measure of the quality of a specific wireless service, such as throughput or roaming

   A single user reports that their video conferencing calls are choppy, but speed tests show good throughput. Client-level SLE shows 'Throughput' is 95%, but 'Jitter' is consistently above the threshold. The packet capture shows the client is using 802.11n with a 20 MHz channel, while other clients on the same AP are using 802.11ac with 80 MHz channels. What is the MOST likely cause of the high jitter?

   • AThe client's 20 MHz channel is too narrow for video conferencing
   • BThe AP's QoS settings are prioritizing other traffic over the video conferencing traffic
   • CThe client's driver is outdated and not compatible with the AP's 802.11ac mode
   • DThe client's legacy 802.11n radio is causing the AP to use protection mechanisms, increasing latency variability
