   A branch has a single LAN interface, and the administrator needs to provide DHCP to devices on two different subnets. The switch does not support VLANs. What is the best way to achieve this?

   • AAssign static IP addresses to all devices on the second subnet
   • BCreate two VLAN interfaces on the LAN interface
   • CUse DHCP relay to forward requests to an external DHCP server that can serve both subnets
   • DConfigure a single DHCP scope with a large subnet that covers both subnets

   An administrator is onboarding a new branch site in Prisma SD-WAN. The site has two WAN links: a primary MPLS circuit and a backup broadband connection. The administrator has already created the site object and added the WAN interfaces. What is the next required step to ensure the branch can forward traffic?

   • AConfigure a routing protocol such as BGP on the WAN links
   • BDefine the WAN link types and set the bandwidth for each link
   • CCreate a security policy to allow traffic from LAN to WAN
   • DConfigure the LAN interface and assign an IP address

   After deploying a new branch site, users report intermittent connectivity to the data center. The administrator checks the Prisma SD-WAN monitoring dashboard and sees that the MPLS link is up but the path quality is poor. What should the administrator do next to troubleshoot?

   • ADisable the backup link to force all traffic over MPLS
   • BReboot the branch device to reset the WAN links
   • CReview the path quality metrics and check for packet loss or jitter on the MPLS link
   • DChange the security policy to allow more traffic

   A branch has a 10 Mbps WAN link. The administrator wants to guarantee 5 Mbps for video conferencing and 3 Mbps for VoIP, but the total guaranteed bandwidth exceeds the link capacity. What should the administrator do?

   • AReduce the guaranteed bandwidth for one of the classes to fit within the link capacity
   • BSet the guaranteed bandwidth to 5 Mbps for video and 3 Mbps for VoIP, and rely on the system to handle the overcommitment
   • CIncrease the link capacity by adding a second WAN link
   • DUse a path selection policy to send video conferencing over a different link
