To assign specific traffic to a route - traffic must be identified by a routing mark. Each packet can only have one routing mark. True. False.

Which type of ip route is the highest priority for routing decision?. OSPF Route. BGP Route. Static Route. Connected Route.

A routing table has following entries: 0 dst-address=10.0.0.0/24 gateway=10.1.5.126 1 dst-address=10.1.5.0/24 gateway=10.1.1.1 2 dst-address=10.1.0.0/24 gateway=25.1.1.1 3 dst-address=10.1.5.0/24 gateway=10.1.1.2 Which gateway will be used for a packet with destination address 10.1.5.126?. 10.1.5.126. 10.1.1.1. 25.1.1.1. 10.1.1.2.

The check-gateway option is enabled for one route. Select all statements that are true: Check gateway option can be configured for Ping, ARP and RARP (Reverse ARP). Gateway is checked every 10 seconds and after a single failure, the gateway is considered unreachable. Gateway is checked every 10 seconds and after 2 failures, the gateway is considered unreachable. In case of failure of the gateway, routes pointing to that gateway will become inactive.

/ip route configuration on router: /ip route add gateway=192.168.0.1 /ip route add dst-address=192.168.1.0/24 gateway=192.168.0.2 /ip route add dst-address=192.168.2.0/24 gateway=192.168.0.3 /ip route add dst-address=192.168.3.0/26 gateway=192.168.0.4 Router needs to send packets to 192.168.3.240.

Route via gateway 1.1.1.1. Route via gateway 2.2.2.2. Route via gateway 3.3.3.3.

What is policy routing for and what criteria can be used to decide appropriate route?. Policy routing can be used to force specific traffic to go different way through network and beside source and destination address any traffic can be marked in firewall can be distinguish traffic. Policy routing can be used to bypass routing table and only active tunnel interfaces can be used to direct traffic alternatively. Policy routing can be used to force specific traffic to go different way through network, but only source and destination address can be used to distinguish traffic. Policy routing can be used to bypass routing table and is possible only if BGP is enabled.

Which routing table is used to apply recursive routing at MikroTik RouterOS?. It is only possible on the x86 platform. It is not possible. It is only possible in the main routing table. It is possible in all the routig tables installed in a router.

Define a routing loop (choose the most precise description). Situation where the packet is routed through the same sequence of routers until the TTL expires. Situation where the packet is routed through the same router twice. Situation where the packet does not reach its destination. Situation where the TTL of the packet expires.

A MikroTik router has the following configuration: /ip address add address=1.1.1.2/30 interface=ether1 add address=2.2.2.2/30 interface=ether2 add address=192.168.10.1/24 interface=ether3 /ip firewall mangle add action=mark-connection chain=prerouting dst-port=80 new-connection-mark=web_c passthrough=yes protocol=tcp add action=mark-routing chain=prerouting connection-mark=web_c new-routing-mark=web passthrough=no /ip firewall nat add action=masquerade chain=srcnat out-interface=ether3 /ip route add gateway=1.1.1.1 add gateway=2.2.2.2 routing-mark=web What can be said about the Web Access (port 80) by a customer connected at ether3 interface with IP 192.168.10.2/24, gateway 192.168.10.1?. The customer is unable to access the web. The customer will access the web using the gateway 1.1.1.1. The customer will access the web by ECMP, by using both gateways 1.1.1.1 and 2.2.2.2. The customer will access the web using the gateway 2.2.2.2.
