When using the ‘check gateway’ function when creating a route, which protocols can be used to ensure that the gateway address is reachable? (select all that apply). ICMP. ARP. UDP. MNDP.

When an ARP request is sent, what type of address does the host expect to receive in the response?. VLAN ID. MAC address. IP address. 802.11g.

What is the maximum number of VLANs supported on a single Ethernet interface in RouterOS?. 63. Unlimited. 511. 4095. 255.

When using the ‘check-gateway=ping’ routing option, what is the ICMP echo request interval (in seconds)?. 60s. 10s. 30s. 20s.

A network administrator observes two different routes to the same destination 10.0.0.0/8, both of which are active. What could cause this?. One route is ‘Static’ and another is OSPF with the same distance. One route is ‘Connected’ and another is ‘Static’. Use of ECMP with two static routes. The routes have different ‘routing-marks’ and belong to different tables.

To securely connect (Layer 2) two remote networks, the following methods can be used: SSTP with BCP or L2TP/IPsec with BCP. EoIP over SSTP or L2TP/IPsec. IPIP with IPsec secret. SSTP or L2TP/IPsec. EoIP with IPsec secret.

Routing marks can be assigned using the mangle firewall in the following chains: postrouting. input. prerouting. output. forward.

There are two gateways to the Internet on different routers with OSPF. One redistributes the default route as type 1 and the other as type 2 (same metric). Which one will be preferred?. RouterOS does not distinguish between types; it chooses based on the lowest cost. Traffic will be balanced between the two. Type 2 will be preferred. Type 1 will be preferred.

In broadcast networks, OSPF depends on the following to function correctly: Broadcast. UDP. TCP. Multicast. ICMP.

Select the correct statements about routing marks: can be assigned by IP firewall mangle chains prerouting and output. each packet can have more than one routing mark. a packet with a routing mark is ignored by main routing table if there is at least one route for the routing mark. check-gateway option is not compatible with routing-mark.

Routing protocols used within the same AS are referred to as Exterior Gateway Protocols. false. true.

On the following network diagram , when ROUTER wants to reach "HOST A" by itself, it should use ISP1 as gateway and when CLIENT wants to reach "HOST A", router should use ISP2 as a gateway. How would you configure routing marks to achieve this?. Chain Forward for a Routing Mark to route to ISP 2 & Chain Forward for a Routing Mark to route to ISP 1. Chain Input for a Routing Mark to route to ISP 2 & Chain Output for a Routing Mark to route to ISP 1. Chain output for a Routing Mark to route to ISP 2 & Chain Output for a Routing Mark to route to ISP 1. Chain Prerouting for a Routing Mark to route to ISP 2 & Chain Output for a Routing Mark to route to ISP 1.

. What is the minimum configuration necessary for establishing an IPIP tunnel?. Port configuration on both sides of the tunnel. Interface of the local and remote router on both sides of the tunnel. Tunnel ID of the local and remote router on both sides of the tunnel. Address of the remote router on both sides of the tunnel.

OSPF starts working on the router as soon as. the routing package is enabled on the router. at least one area is specified in the ospf area menu. at least one IP network is assigned in the ospf network menu. at least one interface is defined in the ospf interface menu.

Which of the following can connect a remote area in OSPF to the backbone area through a non-backbone area?. Backbone Area. Virtual Links. Area Border Router. Internal Router.

What is the protocol number used by the EoIP tunnel, to encapsulate Ethernet frames and send them to the remote side of the EoIP tunnel. 47. 1194. 500. 1723.

/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. Which gateway will be used?. 192.168.0.2. 192.168.0.1. 192.168.0.4. 192.168.0.3.

Select true statements about PPPoE server. You can use different ports to use more than one PPPoE server. PPPoE users can be bound to one specific PPPoE server. There can be more than one PPPoE server on one single interface. For multiple PPPoE servers you need to use different physical interfaces (ethernet or wireless).

There are two routes in the routing table: 0 dst-addr=10.1.1.0/24 gateway=5.5.5.5 1 dst-addr=10.1.1.4/30 gateway=5.6.6.6 Which gateway will be used to get to the IP address 10.1.1.6?. 5.5.5.5. 5.6.6.6. both - half of the traffic will be routed through one gateway, half through the other. the required route is not in the routing table.

Which ones of these are Point-to-Point addresses?. address=10.0.0.1/32 network=10.0.0.0. address=10.0.0.1/32 network=10.0.0.254. address=10.0.0.1/24 network=10.0.0.0. address=1.1.1.1/32 network=10.0.0.0.

Which route will be used to reach host 192.168.1.55? /ip route add disabled=no distance=1 dst-address=192.168.1.0/24 gateway=1.1.1.1 add disabled=no distance=1 dst-address=192.168.1.0/25 gateway=2.2.2.2 add disabled=no distance=1 dst-address=192.168.0.0/16 gateway=3.3.3.3. Route via gateway 3.3.3.3. Route via gateway 2.2.2.2. Route via gateway 1.1.1.1.

Open Shortest Path First is a. Distance vector routing protocol. Link state routing protocol. Hybrid routing protocol.

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, but only source and destination address can be used to 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 bypass routing table and is possible only if BGP is enabled. Policy routing can be used to force specific traffic to go different way through network and beside source and destination address any traffic that can be marked in firewall can be used to distinguish traffic.

Consider the following diagram. Assuming that all the necessary configuration has already been done on R2 (proxy-arp is disabled), to communicate from a device on LAN1 to a device on LAN2, which of the following configurations on R1 would enable this?. /ip route add dst-address=192.168.0.0/24 gateway=192.168.0.1. /ip route add dst-address=192.168.1.0/24 gateway=192.168.99.2. /ip route add dst-address=0.0.0.0/0 gateway=192.168.99.2. /ip route add dst-address=0.0.0.0/0 gateway=Ether1. /ip route add dst-address=192.168.1.0/24 src-address=192.168.0.0/24 gateway=192.168.99.2.

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=10.1.5.0/25 gateway=10.1.1.2 Which gateway will be used for a packet with destination address 10.1.5.126?. 25.1.1.1. 10.1.1.1. 10.1.1.2. 10.1.5.126.
