Explanation
The best way to minimize the BGP configuration and management overhead on on-prem network devices is to summarize BGP routes before advertising them. Route summarization is a technique that reduces the number of routes in a routing table by aggregating multiple routes into a single route with a less specific prefix. This reduces the size of routing updates and the memory and CPU usage of routers. Prisma Access supports route summarization for service connections and remote network connections that use BGP routing1. You should not implement target service connection for traffic steering, as this is a feature that allows you to select a specific service connection for traffic from a remote network connection or a mobile user based on destination IP address or application. This does not affect the BGP configuration ormanagement on on-prem network devices2. You should not implement hot potato routing, as this is a routing technique that selects the closest exit point to the destination network based on the number of hops or the lowest IGP metric. This does not affect the BGP configuration or management on on-prem network devices3. You should not implement default routing, as this is a routing technique that uses a default route to forward packets to an unknown destination. This does not affect the BGP configuration or management on on-prem network devices, and it may not provide optimal routing for Prisma Access traffic4. References: 1:

Step 3. Upload or drag and drop the technical support file.
Step 4. Map the zone type and area of the architecture to each zone.
Step 5.Follow the steps to download the BPA report bundle.

Explanation
When the egress guaranteed bandwidth is exceeded, the firewall passes traffic on a best-effort basis.https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-admin/quality-of-service/qos-concepts/qos-bandwid

Explanation
The engineer can use the test vpn gateway CLI command to manually initiate a VPN tunnel from the CLI.
This command allows the engineer to specify the name of the VPN gateway and the IP address of the peer to initiate an IKE negotiation and establish a VPN tunnel. Option A is incorrect because test vpn flow is not a valid CLI command. Option B is incorrect because test vpn ike-sa is a CLI command that displays information about the IKE security associations, not initiates a VPN tunnel. Option C is incorrect because test vpn tunnel is a CLI command that displays information about the IPSec security associations, not initiates a VPN tunnel.
