Exhibit.

The exhibit shows VPN event logs on FortiGate. In the output shown in the exhibit, which statement is true?

A. There are no IPsec tunnel statistics log messages for ADVPN cuts.
B. The master tunnel T_INET_0 cannot accept the ADVPN shortcut.
C. The VPN tunnel T_MPLS_0 is a shortcut tunnel.
D. There is one shortcut tunnel built from master tunnel T_MPLS_0.

正解：D

解説：
Explanation
VPN event logs record the status of VPN tunnels, such as the establishment, termination, or failure of a tunnel.
The output includes the following information:
logid: the log ID number
type: the log type, either traffic or event
subtype: the log subtype, either vpn or ipsec
level: the log level, either error, warning, or notice
vd: the virtual domain name
logdesc: the log description
msg: the log message
action: the log action, such as tunnel-up, tunnel-down, or tunnel-stats
remip: the remote IP address
locip: the local IP address
remport: the remote port number
locport: the local port number
outintf: the outgoing interface name
cookies: the IKE SA cookies
user: the user name
group: the user group name
useralt: the alternative user name
xauthuser: the XAuth user name
authgroup: the XAuth user group name
assignip: the assigned IP address
vpntunnel: the VPN tunnel name
tunnellip: the tunnel loopback IP address
tunnelid: the tunnel ID number
tunneltype: the tunnel type, either ipsec or ssl
duration: the tunnel duration in seconds
sentbyte: the number of bytes sent
rcvdbyte: the number of bytes received
nextstat: the next statistics interval in seconds
advpnsc: the ADVPN shortcut flag, either 0 or 1
Based on the exhibit, the following statement is true:
There is one shortcut tunnel built from master tunnel T_MPLS_0. This means that the VPN tunnel
T_MPLS_0 is a master tunnel that can send ADVPN shortcut offers to other spokes, and the VPN tunnel
T_MPLS_0_0 is a shortcut tunnel that is built from the master tunnel T_MPLS_01. In the exhibit, the
log action for T_MPLS_0 is tunnel-up, and the log action for T_MPLS_0_0 is shortcut-up. The advpnsc
flag for T_MPLS_0 is 0, indicating that it is not a shortcut tunnel, while the advpnsc flag for
T_MPLS_0_0 is 1, indicating that it is a shortcut tunnel.

質問 # 31
In the default SD-WAN minimum configuration, which two statements are correct when traffic matches the

正解：A、B

質問 # 32
Exhibit.

The exhibit shows the output of the command diagnose sys sdwan health-check status collected on a FortiGate device. Which two statements are correct about the health check status on this FortiGate device? (Choose two.)

A. The interface T_INET_1 missed one SLA target.
B. The health-check VPN_PING orders the members according to the lowest jitter.
C. The interface T_INET_0 missed three SLA targets.
D. There is no SLA criteria configured for the health-check Level3_DNS.

正解：B、D

解説：
According to the FortiGate / FortiOS 6.4.2 Administration Guide, the health check status command displays the status of the health check probes for each SD-WAN member interface. The output includes the following information:
state: the current state of the interface, either alive or dead
packet-loss: the percentage of packets lost during the health check
latency: the average round-trip time in milliseconds
jitter: the variation in latency
mos: the mean opinion score, a measure of voice quality
bandwidth: the available bandwidth in kilobits per second for each direction (up, down, bi) sla map: a bitmap that indicates which SLA criteria are met or failed Based on the exhibit, the following statements are correct:
The health-check VPN_PING orders the members according to the lowest jitter. This means that the interface with the lowest jitter value is listed first, followed by the next lowest, and so on1. In the exhibit, the order is T_MPLS, T_INET_1, and T_INET_0.
There is no SLA criteria configured for the health-check Level3_DNS. This means that the health check does not use any SLA parameters to determine the state of the interface2. In the exhibit, the sla map value is 0x0 for both port1 and port2, indicating that no SLA criteria are applied.

質問 # 46
Refer to the exhibit.

Which statement explains the output shown in the exhibit?

A. FortiGate must re-evaluate the session due to routing change.
B. FortiGate will not re-evaluate the session following a firewall policy change.
C. FortiGate performed standard FIB routing on the session.
D. FortiGate used 192.2.0.1 as the gateway for the original direction of the traffic.
