NO.15 Refer to the exhibits.

An administrator is attempting to advertise the network configured on port3. However, FGT-A is not receiving the prefix.
Which two actions can the administrator take to fix this problem? (Choose two.)

Modify the prefix using the network command from 172.16.0.0/16 to 172.16.54.0/24.

Manually add the BGP route on FGT-A.

Restart BGP using a soft reset to force both peers to exchange their complete BGP routing tables.

Use the set network-import-check disable command.

NO.16 Refer to the exhibit, which shows a partial output of the fssod daemon real-time debug command.

What two conclusions can you draw Itom the output? (Choose two.)

The workstation with IP 10.124.2.90 will be polled frequently using TCP port 445 to see if the user is still logged on.

The logon event can be seen on the collector agent installed on Windows.

FSSO is using DC agent mode to detect logon events.

FSSO is using agentless polling mode to detect logon events.

NO.17 Refer to the exhibit, which shows the output of the command get router info ospf neighbor.

To what extent does FortiGate operate when looking at its OSPF neighbors? (Choose two.)

The local FortiGate has at least one interface that participates in a broadcast network.

The local FortiGate has at least one interface that participates in a point-to-point network.

The local FortiGate is the DR.

Neighbor 0.0.0.18 is the designated router (DR).

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. Pagina 439 Network_Security_Support_Engineer_7.4_Study FULL/- This represents a point-to-point network

NO.18 Which exchanges are the first two exchanges in IKEv2 negotiation?

INIT_Req and Auth_Request

IKE SA_INIT and IKE_Auth

Key Exchange and Authentication

Init_Req and Wait_Init_Req

The first IKEv2 exchange is the SA_INIT, where algorithms, nonces, and Diffie Hellman values are negotiated. The second is the AUTH exchange, which carries peer authentication and completes the IKE SA setup.

NO.19 Refer to the exhibit, which displays the output of a real-time debug.

Which statement accurately describes this output?

Access to the requested website was allowed by web filter profile ftgd-allow.

The server hostname was extracted either from the common name (CN) in the server certificate or the server name indication (SNI) in the client request.

The URL requested was detected to belong to FortiGuard category ID 255.

The urlfilterdebug detected a category mismatch.

The hostname=”training.fortinet.com”field only appears when FortiGate learns the HTTPS hostname via SNI (in the TLS Client Hello) or by parsing the server certificate’s CN-it isn’t gleaned from any HTTP headers over an encrypted tunnel.

NO.20 Refer to the exhibit.
The exhibit shows the output from using the command diagnose debug application samld -1 to diagnose a SAML connection.

Based on this output, what can you conclude?

Active Directory is used for authentication.

The authentication request is for an SSL VPN connection.

The IdP IP address is 10.1.10.254.

The IdP IP address is 10.1.10.2.

NO.21 Which two statements about conserve mode are true? (Choose two.)

FortiGate exits conserve mode when the system memory goes below the configured green threshold.

FortiGate starts dropping all new sessions when the system memory reaches the configured red threshold.

FortiGate starts taking the configured action for new sessions requiring content inspection when the system memory reaches the configured red threshold.

FortiGate enters conserve mode when the system memory reaches the configured extreme threshold.

NO.22 Refer to the exhibit.

Assuming a default configuration, which three statements are true? (Choose three.)

Strict RPF is enabled by default.

User B: Fail. There is no route to 95.56.234.24 using wan2 in the routing table.

User A: Pass. The default static route through wan1 passes the RPF check regardless of the source IP address.

User B: Pass. FortiGate will use asymmetric routing using wan1 to reply to traffic for 95.56.234.24.

User C: Fail. There is no route to 10.0.4.63 using port1 in the touting table.

NO.23 Refer to the exhibits.

An administrator Is expecting to receive advertised route 8.8.8.8/32 from FGT-A. On FGT-B, they confirm that the route is being advertised and received, however, the route is not being injected into the routing table.
What is the most likely cause of this issue?

A batter route to the 8.8.8.8/32 network exists in the routing table.

FGT-B is configured with a prefix list denying the 8.8.8.8/32 network to be injected into the routing table.

The administrator has misconfigured redistribution of routes on FGT-A.

FGT-8 is configured with a distribution list denying the 8.8.8.8/32 network to be injected into the routing table.

NO.24 What are two reasons you might see iprope_in_check() check failed, drop when using the debug flow? (Choose two.)

Packet was dropped because of policy route misconfiguration.

Packet was dropped because of traffic shaping.

Trusted host list misconfiguration.

VIP or IP pool misconfiguration.

VIP or IP pool misconfiguration.
If a VIP or IP pool maps an address to the FortiGate itself, traffic destined for that address is treated as “local in,” and iprope_in_check()will drop it when the FortiGate thinks it owns the IP Trusted host list misconfiguration.
Management or local in traffic (HTTPS, SSH, ping, etc.) hitting a FortiGate interface is subject to the trusted host list on that interface. If the source IP isn’t permitted, iprope_in_check()will catch and drop it

NO.25 View the exhibit:

Given the output showing a real-time debug, which statement describes why the update is failing?

The update should be using port 53 or port 8888, instead of port 443.

The administrator should use the execute update-wf command instead.

FortiGate is unable to establish a TCP connection with FDS.

FortiGate is unable to resolve the required FQDN (service.fortiguard.net) for antivirus and IPS updates.

NO.26 Which statement about IKEv2 is true?

Both IKEv1and IKEv2 share the feature of asymmetric authentication.

IKEv1and IKEv2 have enough of the header format in common that both versions can run over the same UDP port.

IKEv1and IKEv2 use same TCP port but run on different UDP ports.

IKEv1and IKEv2 share the concept of phase1and phase2.

NO.27 Refer to the exhibit, which contains the partial configuration of an IPsec VPN configuration.

After reviewing the configuration, what can you conclude about the IPsec VPN Phase 1 setup?

The VPN is configured using IKEv2.

Dead Peer Detection is disabled.

The VPN is configured with DHCP over IPsec.

The tunnel is configured as a route-based VPN.

The use of a phase1-interface indicates this is a route based IPsec tunnel (it creates a virtual interface rather than using policy based selectors).

NO.28 Refer to the exhibit, which shows a session entry.

Which statement about this session is true?

Return traffic to the initiator is sent to 10.1.0.1.

Return traffic to the initiator is sent lo 10.200.1.254.

It is an ICMP session from 10.1.10.10 to 10.200.1.1.

It is an ICMP session from 10.1.10.1 to 10.200.5.1.
