NSE7_FSN_AR-7.6 Exam Dumps - Fortinet NSE 7 - Secure Networking 7.6 Architect

The command on this slide shows a summary of the statuses of all the OSPF neighbors. For each neighbor, it displays the adjacency state and if it is a DR, a BDR, or neither (DROther) Pagina 362 Enterprise_Firewall_7.2_Study. - Point-to-point networks contain only two peers, one at each end of a point-to-point link - Broadcast networks (multi-access) support more than two attached routers. They also support sending messages to multiple recipients (broadcasting). Pagina 365 Enterprise_Firewall_7.2_Study. In any multi-access network there is one DR and one BDR.

The exhibit identifies the root VDOM as the management VDOM, indicated by the green check mark. The Enterprise Firewall 7.6 Administrator Study Guide explains that the management VDOM handles FortiGuard database downloads, license validation, and FortiGuard rating connectivity on behalf of the entire FortiGate system. It states that FortiGuard updates obtained through the management VDOM “will affect all VDOMs.”

Consequently, the root VDOM must reach either a public Fortinet Distribution Network server or a FortiManager configured as a FortiGuard Distribution Server in an isolated environment. The guide specifically identifies connectivity to “a FortiManager serving as a FortiGuard Distribution Server (FDS) in a closed network” as the alternative to public FortiGuard access. Loss of both paths prevents Core1 and Core2 from using current FortiGuard web-filtering information. Therefore, options A and B are correct.

Core1 and Core2 do not need to become management VDOMs; FortiGate uses one designated management VDOM for these system-level services. A VDOM link is used to route user traffic between VDOMs and is not required for distributing FortiGuard services, eliminating option D.

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 C, D, and E.

The study guide lists the exact OSPF adjacency requirements:

“Interfaces of peers are the same type and in the same OSPF area”

“Each peer has a unique router ID”

“OSPF authentication, if enabled, is successful”

These map directly to:

C. OSPF interface network types match

D. Authentication settings match

E. OSPF router IDs are unique

The same study-guide slide also states other requirements such as:

peers’ primary IPs must be in the same subnet with the same mask

hello and dead intervals must match

OSPF MTUs must match

Why the other options are wrong:

A is wrong because link cost matching is not listed as an adjacency requirement. OSPF cost affects path selection, not whether adjacency can form.

B is wrong because interface priority does not need to be unique. Priority is used for DR/BDR election, where the highest priority wins, and ties are broken by router ID.

So the verified answers are: C, D, E.
