The ISDB applies rules to traffic from specific sources, based on application type. The ISDB requires application control to maintain signatures and perform load-balancing. The ISDB contains the IP addresses and port ranges of well-known destinations.
43. Which statement about using BGP routes in SD-WAN is true? Adding static routes must be enabled on all ADVPN interfaces. VPN topologies must be form using only BGP dynamic routing with SD-WAN Learned routes can be used as dynamic destinations in SD-WAN rules Dynamic routing protocols can be used only with non-encrypted traffic.
44. An administrator is troubleshooting VoIP quality issues that occur when calling external phone numbers The SD-WAN interface on the edge FortiGate is configured with the default settings, and is using two upstream links One link has random jitter and latency issues and is based on a wireless connection.
Which two actions must the administrator apply simultaneously on the edge FortiGate to improve VoIP quality using SD_WAN rules? (Choose two.) Select the corresponding SD-WAN balancing strategy in the SD-WAN rule. Choose the suitable interface based on the interface cost and weight. Use the performance SLA targets to detect latency and jitter instantly. Place the troublesome link at the top of the interface preference list.

Which statement about the ADVPN device role in handling traffic is true? Two spokes 100.64.3.1 and 10.1.2. 254 forward their queries to their hubs This is a hub that has received a query from a spoke and has forwarded it to another spoke This is a spoke that has received a query from a remote hub and has forwarded the response to its hub Two hubs. 10.1.1.254 and 10.1.2.254, are receiving and forwarding queries between each other.
47. Which statement is correct about the SD-WAN and ADVPN? ADVPN interface can be a member of SD-WAN interface. Dynamic VPN is not supported as an SD-Wan interface. Spoke support dynamic VPN as a static interface. Hub FortiGate is limited to use ADVPN as SD-WAN member interface.

FEC transmits additional packets as redundant data to the remote device. FEC reduces the stress on the remote device jitter buffer to reconstruct packet loss.
49. Which action FortiGate performs on traffic that is subject to a per-IP traffic shaper of 10 Mbps? FortiGate shares 10 Mbps of bandwidth equally among all source IP addresses.

FortiGate creates a single IPsec virtual interface that is shared by all clients. FortiGate maps the remote gateway 100.64.3.1 to tunnel index interface 1. FortiGate does not install IPsec static routes for remote protected networks in the routing table.
72. Which two statements describe how IPsec phase 1 aggressive mode is different from main mode when performing IKE negotiation? (Choose two) A peer ID is included in the first packet from the initiator, along with suggested security policies.

The use of Diffie Hellman keys is limited by the responder and needs initiator acceptance.
73. Which two benefits from using forward error correction (FEC) in IPsec VPNs are true? (Choose two.) FEC transmits the original payload in full to recover the error in transmission. FEC reduces the stress on the remote device buffer to reconstruct packet loss. FEC transmits additional packets as redundant data to the remote device. FEC improves reliability, which overcomes adverse WAN conditions such as noisy links.
