   A multinational corporation uses Routing Assurance to monitor a critical inter-site link. The link is a 500 Mbps dedicated circuit. Over the past week, the following observations were made: (1) Latency is consistently 40 ms, which is 10 ms higher than the baseline of 30 ms. (2) Jitter is 5 ms, within normal limits. (3) Packet loss is 0.1%, which is normal. (4) The Path Health score has dropped from 95 to 70. (5) Users report that file transfers between the sites are slower than usual. The network team has verified that the circuit provider has not reported any issues. Which of the following is the most likely root cause of the performance degradation?

   • AThe packet loss of 0.1% is causing the file transfer slowdown
   • BThe jitter of 5 ms is causing the file transfer slowdown
   • CThe circuit provider is throttling the bandwidth
   • DThe increased latency is due to a routing change that sends traffic over a longer path

   A university with multiple campuses uses Routing Assurance to monitor inter-campus links. The system has been collecting data for three months. Recently, a link that normally has 5 ms latency began showing 20 ms latency every weekday from 9:00 AM to 5:00 PM. The Mist AI engine has not generated an alert. What is the most likely reason for the lack of alert?

   • AThe latency increase is below the static threshold of 25 ms
   • BThe link is not configured for Routing Assurance monitoring
   • CThe Mist AI engine has learned this as a normal pattern and has adjusted the baseline accordingly
   • DThe alert notification email server is misconfigured

   A managed service provider (MSP) monitors multiple customer networks using Juniper Mist. They want to enable Routing Assurance for a new customer's WAN links. The customer has Juniper SRX series firewalls at each site. What is the first step the MSP must take to enable Routing Assurance for this customer?

   • ACreate a new Mist organization for the customer
   • BSet up a VPN tunnel between the customer sites and the Mist cloud
   • CConfigure the SRX devices to send SNMP traps to the Mist cloud
   • DEnsure the SRX devices are adopted and managed by the Mist cloud

   A hospital network uses Routing Assurance to monitor the link between its main campus and a remote clinic. The link normally has 2 ms latency and 0.1% loss. During a routine backup window (2:00 AM to 3:00 AM), latency rises to 50 ms and loss to 2%, but no alert is generated. The network team wants to be notified when the link degrades outside of normal business hours. What should they configure to achieve this?

   • AA static threshold alert set to trigger when latency exceeds 30 ms at any time
   • BA notification rule that sends an email only when the path health score drops below 50
   • CAn alert that triggers only when jitter exceeds 10 ms
   • DA custom baseline that excludes the backup window, with alerts triggered when metrics deviate from that baseline
