The session output reveals a session with proto=1 (ICMP) and the origin and reply directions show address and NAT translations. Specifically, the hook=post dir=org act=snat shows that source NAT is performed for outgoing packets, where the source 10.1.10.10:40602 is translated to 10.200.5.1:8 (likely ICMP id 8, not a TCP/UDP port). The reply direction, hook=pre dir=reply act=dnat, indicates destination NAT for incoming packets: packets incoming for 10.200.5.1:60430 are destination-NATed to 10.1.10.10:40602. The gateway (gwy) is listed as 10.200.1.254/10.1.0.1, which for outgoing traffic means that return traffic is directed to the gateway (10.200.1.254), per the NAT policy. This is confirmed by the FortiOS Session Table Guide, which explains that the returned ICMP reply will be routed out to this NAT gateway. The session statistics and logical flow (SNAT out, matching DNAT in) reinforce that reply traffic to the initiator traverses via
10.200.1.254.

The study guide states:
"The kernel memory slabs are collections of objects with a common purpose. The kernel uses them to store information in memory." It also gives the exact calculation rule:
"Total slab size = available objects x object size"
From the exhibit:
* tcp_session 3 5 1500 ...
So:
* available objects = 5
* object size = 1500
Therefore:
Total slab size = 5 × 1500 = 7500 kB
That makes D correct, and it is associated with the kernel , not user space.
Why the other options are wrong:
* A is wrong because sctp_session 0 0 1600 ... gives 0 × 1600 = 0 , but slabs are associated with the kernel , not user space.
* B is wrong because ip_session 1 3 1200 ... gives 3 × 1200 = 3600 , but again slabs are kernel memory, not user space.
* C is wrong because ip6_session 0 0 1300 ... gives 0 × 1300 = 0 , not 1300.

The correct answers are A, D, and E . This is a feasible path RPF check scenario. In FortiGate's default RPF behavior, FortiGate checks whether the routing table contains a valid return route to the source IP address through the same interface on which the packet arrived . The study guide's RPF feasible path example states that FortiGate "checks the routing table for a route that matches the source address and incoming interface of the first original packet." It then gives the exact result: User A passes because "there is a default route through wan1," so packets received on wan1 pass the RPF check regardless of source address.
User B fails because FortiGate does not have a route to 95.56.234.24 through wan2 . User C fails because FortiGate does not have a route to 10.0.4.63 through port1 . Therefore, option B is wrong because FortiGate is not allowing asymmetric return routing here. Option C is wrong because the default route points out wan1 , not port1 , so it cannot validate User C's packet arriving on port1.
