Sophos ET80 - Routing and SD-WAN on Sophos Firewall WITH 100% CORRECT ANSWERS

What are the three types of configurable routes on a Sophos Firewall? Static, SD-WAN and Dynamic What is a static route? Traffic sent to a specific gateway based on destination only What is an SD-WAN route? They can route traffic depending on source, service, application and user. This can also route to a specific gateway, or backup gateway depending on health monitoring. You can also select a gateway on quality metrics or load balancing. What is a dynamic route? Routes learned by communicating with other routing devices on the network Where would you go to configure a static route? Configure, routing then Static routes Where would you go to configure a gateway? Configure, Routing then Gateways Where would you go to configure a SD-WAN route? Configure, Routing then SD-WAN What can be used to define what routes traffic is routed through using SD-WAN? The interface traffic arrives on, the source and destination networks, the service, DSCP marking, user and application objects What is a DSCP Value? Its an 8-but value of the IP header to classify data packets and manage network traffic What happens if Primary and Backup gateways are used in an SD-WAN route? Traffic will be routed via a certain gateway depending on the health status of the primary gateway, if this is healthy it will be preferred, however if this is down it will use the backup Routes are processed in order of precedence, true or false? True What is the default order of route precedence? 1. Health Check Routes 2. Static Routes 3. SD-WN Routes 4. IPsec VPN Routes 5. Default Routes Where can the order of route precedence be modified? Command line What command is used to show the route precedence? System route_precedence show What command is used to set the route precedence? System route_precedence set What is the WAN link manager used for? Configuring the WAN connections for multiple WAN gateways What happens if a WAN gateway is set to Backup? It will become active when the failover threshold is met, such as an active or specific gateway fails What happens if there are multiple active gateways? Traffic will be load balanced between them What can the WAN link manager be configured? Configure, Network then WAN link manager What happens when a backup WAN gateway actives? It will be configured to either inherit the weight of the failed active gateway, or just the weight configured in the backup gateway What does a SD-WAN profile control? Routing across multiple gateways based on the performance of the link, optimising network performance. Alternatively, you can load balance connections and route traffic based on SLA What performance criteria can the SLA of an SD-WAN profiles be set to? Latency, Jitter or Packet loss What protocol can you use to run a health check of an SD-WAN profile? Ping or TCP
