Explanation
The destination zone in the NAT rule is determined after the route lookup of the destination IP address in the original packet (that is, the pre-NAT destination IP address).
https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-networking-admin/nat/nat-configuration-examples/destina The NAT rule destination zone should be set to the zone where the traffic is destined before NAT. In this case, the traffic from the internet is destined to the pre-NAT IP address of the server, which is 153.6.12.10. This IP address belongs to the Outside zone, as shown in the routing and interfaces information. Therefore, the NAT rule destination zone should be set to Outside. The other options are not correct. None is not a valid option for the NAT rule destination zone. Inside and DMZ are the zones where the traffic is destined after NAT, which is
192.168.10.10. References: :

Explanation
According to the PCNSE Study Guide , SSL forward proxy is a feature that allows the firewall to decrypt and inspect SSL traffic going to external sites. The firewall acts as a proxy between the client and the server, generating a certificate on the fly for each site.
The best practices for configuring SSL forward proxy are
Use a forward trust certificate that is signed by a certificate authority (CA) that is trusted by the clients.
This certificate is used to sign certificates for sites that have valid certificates from trusted CAs. The clients will not see any certificate errors if they trust the forward trust certificate.
Use a forward untrust certificate that is not signed by a trusted CA. This certificate is used to sign certificates for sites that have invalid or untrusted certificates. The clients will see certificate errors if they do not trust the forward untrust certificate. This helps alert users of potential risks and prevent man-in-the-middle attacks.
Do not store the forward trust or untrust certificates on an HSM (hardware security module). The HSM does not support on-the-fly signing of certificates, which is required for SSL forward proxy.

Explanation
The addresses used in destination NAT rules always refer to the original IP address in the packet (that is, the pre-translated address). The destination zone in the NAT rule is determined after the route lookup of the destination IP address in the original packet (that is, the pre-NAT destination IP address). The addresses in the security policy also refer to the IP address in the original packet (that is, the pre-NAT address). However, the destination zone is the zone where the end host is physically connected. In other words, the destination zone in the security rule is determined after the route lookup of the post-NAT destination IP address.

Explanation
https://docs.paloaltonetworks.com/pan-os/10-2/pan-os-admin/policy/use-address-object-to-represent-ip-addresse An IP Wildcard Mask address object is useful for internal devices where the addressing structure assigns meaning to certain bits in the address, as illustrated in the diagram. An IP Wildcard Mask address object specifies which source or destination addresses are subject to a Security policy rule. A zero ( 0 ) bit in the mask indicates that the bit being compared must match the bit in the IP address that is covered by the zero. A one ( 1 ) bit in the mask (a wildcard bit) indicates that the bit being compared need not match the bit in the IP address1. For example, if you want to match all cash registers in the northeastern U.S., you can use an IP Wildcard Mask address object of 10.132.1.0/0.0.2.255, which will match any IP address from 10.132.1.0 to
10.132.3.255. References: 1:
