Which conclusion about the packet debug flow output is correct?

• A.The total number of daily sessions for 10.1.10.1 exceeded the maximum number of concurrent sessions configured in the traffic shaper, and the packet was dropped.
• B.The packet size exceeded the outgoing interface MT
• C.The number of concurrent sessions for 10.1.10.1 exceeded the maximum number of concurrent sessions configured in the traffic shaper, and the packet was dropped.
• D.The number of concurrent sessions for 10.1.10.1 exceeded the maximum number of concurrent sessions configured in the firewall policy, and the packet was dropped.

정답:
Explanation:
In a Per-IP shaper configuration, if an IP address exceeds the configured concurrent session limit, the message "Denied by quota check" appears. SD-WAN 7.0 Study Guide page 287

Question No : 7

Which two statements about SD-WAN central management are true? (Choose two.)

• A.The objects are saved in the ADOM common object database.
• B.It does not support meta fields.
• C.It uses templates to configure SD-WAN on managed devices.
• D.It supports normalized interfaces for SD-WAN member configuration.

답을 확인하기

정답:
Explanation:
Normalized interfaces are not supported for SD-WAN templates. You can create multiple SD-WAN zones and add interface members to the SD-WAN zones. You must bind the interface members by
name to physical interfaces or VPN interfaces. https://docs.fortinet.com/document/fortigate/7.0.0/sd-wan-new-features/794804/new-sd-wan-template-fmg

Question No : 8

Refer to the exhibit.



Based on the exhibit, which two actions does FortiGate perform on sessions after a firewall policy change? (Choose two.)

• A.FortiGate flushes all sessions.
• B.FortiGate terminates the old sessions.
• C.FortiGate does not change existing sessions.
• D.FortiGate evaluates new sessions.

답을 확인하기

정답:
Explanation:
FortiGate not to flag existing impacted session as dirty by setting firewall-session-dirty to check new.
The results is that FortiGate evaluates only new session against the new firewall policy.

Question No : 9

Refer to the exhibit.



An administrator is troubleshooting SD-WAN on FortiGate. A device behind branch1_fgt generates traffic to the 10.0.0.0/8 network. The administrator expects the traffic to match SD-WAN rule ID 1 and be routed over T_INET_0_0. However, the traffic is routed over T_INET_1_0.
Based on the output shown in the exhibit, which two reasons can cause the observed behavior? (Choose two.)

• A.The traffic matches a regular policy route configured with T_INET_1_0 as the outgoing device.
• B.T_INET_1_0 has a lower route priority value (higher priority) than T_INET_0_0.
• C.T_INET_0_0 does not have a valid route to the destination.
• D.T_INET_1_0 has a higher member configuration priority than T_INET_0_0.

Question No : 10

Which two statements are correct when traffic matches the implicit SD-WAN rule? (Choose two.)

• A.The sdwan_service_id flag in the session information is 0.
• B.All SD-WAN rules have the default setting enabled.
• C.Traffic does not match any of the entries in the policy route table.
• D.Traffic is load balanced using the algorithm set for the v4-ecmp-mode setting.

답을 확인하기

정답:
Explanation:
sdwan_service_id is 0 = match SD-WAN implicit rule, study guide 7.0 page 120, 7.2 page 149 SD-WAN rules internally are interpreted as a Policy route, so when the traffic doesn't match with any policy route, it will be flowing by implict policy.

• A.port1 is assigned a manual IP address.
• B.port1 is referenced in a firewall policy.
• C.port2 is referenced in a static route.
• D.port1 and port2 are not administratively down.

Which configuration change is required if the responder FortiGate uses a dynamic routing protocol to exchange routes over IPsec?

• A.type must be set to static.
• B.mode-cfg must be enabled.
• C.exchange-interface-ip must be enabled.
• D.add-route must be disabled.

답을 확인하기

정답:
Explanation:
for using "non ike" routes (for example BGP/static and so on) you must do disable the add-route that
inject automatically kernel route based on p2 selectors from the remote site from the SD-WAN_7.2_Study_Guide page 236

• B.The measured bandwidth is less than 100 KBps.
• C.The traffic shaper drops packets if the bandwidth exceeds 6250 KBps.
