NEW QUESTION 61
Consider the scenario where the server name indication (SNI) does not match either the common name (CN) or any of the subject alternative names (SAN) in the server certificate.
Which action will FortiGate take when using the default settings for SSL certificate inspection?

FortiGate uses the SNI from the user’s web browser.

FortiGate closes the connection because this represents an invalid SSL/TLS configuration.

FortiGate uses the first entry listed in the SAN field in the server certificate.

FortiGate uses the ZN information from the Subject field in the server certificate.

NEW QUESTION 62
Refer to the exhibit, which shows the output of a BGP debug command.

Why has the local router at 172.16.23.58 been unable to establish adjacency with its only neighbor?

The local router has not received a keepalivemessage from the neighbor.

There is no active route to the BGP neighbor.

The local router has not received a SYN/ACKpacket from the neighbor.

The local router has not received an OPENmessage from the neighbor.

In BGP’s Connect state the router has sent the initial TCP SYN but hasn’t received the SYN/ACK from its peer, so the TCP handshake never completes and adjacency can’t form.

NEW QUESTION 63
During which phase of IKEv2 does the Diffie-Helman key exchange take place?

IKE_Req_INIT

Create_CHILD_SA

IKE_Auth

IKE_SA_INIT

NEW QUESTION 64
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.

NEW QUESTION 65
Which three common FortiGate-to-collector-agent connectivity issues can you identify using the FSSO real-time debug? (Choose three.)

Log is full on the collector agent.

Inability to reach IP address of the collector agent.

Refused connection. Potential mismatch of TCP port.

Mismatched pre-shared password.

Incompatible collector agent software version.

When you enable FSSO real time debug you’ll see explicit socket errors if the FortiGate can’t reach the collector’s IP (e.g. timeout or “no route to host”), which tells you the agent isn’t reachable. If the TCP port is wrong or the listener isn’t running, you’ll see “Connection refused” in the debug output, pinpointing a port mismatch. And if the configured pre shared secret doesn’t match, the logs show an authentication failure or “invalid key” message, clearly indicating a password mismatch. These three conditions – unreachable IP, refused connection, and bad PSK – are all directly diagnosable via the real time debug.

NEW QUESTION 66
Exhibit.

Refer to the exhibit, which shows a partial output of diagnose hardware aysinfo memory.
Which two statements about the output are true? (Choose two.)

There are 98908 kB o! memory that will never be used.

The user space has 708880 kB of physical memory that is not used by the system.

The I/O cache, which has 641364 kB of memory allocated to it.

The value indicated next to the inactive heading represents the currently unused cache page.

NEW QUESTION 67
Which authentication option can you not configure under config user radius on FortiOS?

mschap

pap

mschap2

eap

NEW QUESTION 68
Which exchanges are the first two exchanges in IKEv2 negotiation?

INIT_Req and Auth_Request

Key Exchange and Authentication

IKE SA_INIT and IKE_Auth

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.

NEW QUESTION 69
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.

BGP’s network statement only advertises prefixes that exactly match routes in the RIB by default.
Since port3 is 172.16.54.0/24, changing the prefix to 172.16.54.0/24 ensures it’s in the routing table and will be advertised.
You can disable the network import check global (or per prefix) setting so FortiGate will advertise the 172.16.0.0/16 prefix even though no matching route exists in the RIB.

NEW QUESTION 70
Refer to the exhibit, which shows the output of the get router info bgp summary command.

Which statement regarding adjacencies between the local router and its neighbors is correct?

The local router and neighbor 100.64.2.254are unable to establish adjacency because their BGP table versions are different.

The local router and neighbor 100.64.2.254are unable to establish adjacency because the TCP session could not be established.

The local router and neighbor 100.64.2.254are unable to establish adjacency because AS 100 is already used by neighbor 100.64.1.254.

The local router and neighbor 100.64.1.254established adjacency because their BGP table versions are identical.

The “never” in the Up/Down column for 100.64.2.254 indicates the BGP TCP connection was never brought up, so no adjacency was formed.

NEW QUESTION 71
Refer to the exhibit.

An IPsec VPN tunnel is dropping, as shown by the debug output.
Analyzing the debug output, what could be causing the tunnel to go down?

Phase 2 drops but Phase 1 is up.

Dead Peer Detection is not receiving its acknowledge packet.

The tunnel drops during rekey negotiation.

The tunnel drops after the timer expires.

NEW QUESTION 72
Exhibit.

Refer to the exhibit, which shows the output of get system ha status.
NGFW-1 and NGFW-2 have been up for a week.
Which two statements about the output are true? (Choose two.)

If a configuration change is made to the primary FortiGate at this time, the secondary will initiate a synchronization reset.

If port 7 becomes disconnected on the secondary, both FortiGate devices will elect itself as primary.

If FGVM…649 is rebooted. FGVM…650 will become the primary and retain that role, even after FGVM…649 rejoins the cluster.

If no action is taken, the primary FortiGate will leave the cluster because of the current sync status.

NEW QUESTION 73
Refer to the exhibit, which shows the output o! the BGP database.

Which two statements are correct? (Choose two.)

The advertised prefix of 10.20.30.0’24 was configured using the network command.

The first four prefixes are being advertised using a legacy route advertisement.

The advertised prefix of 10.20.30.0’24 is being advertised through the redistribution of another routing protocol.

The output shows all prefixes advertised by all neighbors as well as the local router.

NEW QUESTION 74
Refer to the exhibit, which shows partial outputs from two routing debug commands.

Which change must an administrator make on FortiGate to route web traffic from internal users to the internet, using ECMP?

Set snat-route-change to enable.

Set the priority of the static default route using port2 to 1.

Set preserve-session-route to enable.

Set the priority of the static default route using port1 to 10.

NEW QUESTION 75
Refer to the exhibit, which shows the modified output of the routing kernel.

Which statement is true?

The egress interface associated with static route 8.8.8.8/32 is administratively up.

The default static route through 10.200.1.254 is not in the forwarding information base.

The default static route through port2 is in the forwarding information base.

The BGP route to 10.0.4.0/24 is not in the forwarding information base.

NEW QUESTION 76
Refer to the exhibit, which shows one way communication of the downstream FortiGate with the upstream FortiGate within a Security Fabric.

What three actions must you take to ensure successful communication? (Choose three.)

You must authorize the downstream FortiGate on the root FortiGate.

FortiGate must not be in NAT mode.

Ensure TCP port 8013 is not blocked along the way.

You must enable Security Fabric/Fortitelemetry on the receiving interface of the upstream FortiGate.

Ensure the port for Neighbor Discovery has been changed.

Authorize the downstream FortiGate on the root FortiGate.
Only registered/authorized devices can join the Security Fabric.
Ensure TCP port 8013 is not blocked along the path.
Port 8013 carries the Fabric control/telemetry session, so it must be open end to end.
Enable Security Fabric/FortiTelemetry on the upstream FortiGate’s receiving interface.
Telemetry must be activated on the interface that accepts the downstream FortiGate’s connection.

NEW QUESTION 77
Refer to the exhibit, which shows the output of the command get router info bgp neighbors 100.64.2.254 advertised-routes.

What can you conclude from the output?

The BGP state of the two BGP participants is OpenConfirm.

The router ID of the neighbor is 100.64.2.254.

The BGP neighbor is advertising the 10.20.30.40/24 network to the local router.

The local router is advertising the 10.20.30.40/24 network to its BGP neighbor.

NEW QUESTION 78
Refer to the exhibit, which shows the output of a policy route table entry.

Which type of policy route does the output show?

An ISDB route

A regular policy route

A regular policy route, which is associated with an active static route in the FIB

An SD-WAN rule

From the reference to the “internet service(1): Fortinet-FortiGuard(…)” object in the output, it is clear that this policy route entry is using an Internet Service Database (ISDB) object rather than a conventional address object.

NEW QUESTION 79
Refer to the exhibit, which shows a partial output of a real-time LDAP debug.

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