Initialization, Session confirmation, Request and Offer 9. A network administrator checks the IP routing table (/ip route print) and notices that there are two different routes (different /ip route entries) to the destination network 10.0.0.0/8. Each one has exactly one gateway (which is different to the other) and both are active (flag A). What could cause this behaviour of 2 routing entries to the same network with both being active? (choose all possible answers) A. The administrator is using ECMP - (they have added 2 static routes to the network to load balance with ECMP) B. The routes have different 'routing-mark' parameters and belong to two different routing tables C. One of the routes is of type 'Static' and one is from OSPF, but they have the same distance D. One of the routes is of type 'Connected' and the other one is of type 'Static' 10. PPPoE server only works within one Ethernet broadcast domain that it is connected to. If there is a router between server and end-user host, it will not be able to create PPPoE tunnel to that PPPoE server. false
11. It is possible to filter ospf routes within a single ospf area true
12. You have a router with the following IP addresses: ether1: 10.40.1.1/24 ether2: 10.250.1.1/30 ether3: 10.251.1.1/30 wlan1: 10.50.1.1/30 wlan2: 10.50.2.1/30 You have a customer directly connected to ether2, and another customer directly connected to ether3. Your wireless radios are used for wireless connectivity to two different towers, and ether1 goes to another wireless access point for other subscribers. You need all of the subnets distributed across your OSPF Network You need to configure OSPF to talk on this router, what would be the best configuration. A. Set Ethernet 2 and 3 to passive mode B. Set Distribute-Connected=yes C. Set OSPF Networks to 10.40.1.0/24,
10.250.1.0/30, 10.251.1.0/30, 10.50.1.0/30, and 10.50.2.0/30 D. Set Ethernet 1, 2, and 3 to passive mode E. set distribute-default=always-type-1 F. Set OSPF networks to 0.0.0.0/0 G. Set OPSF networks to 10.0.0.0/8 only H. set distribute-state=yes I. Set OSPF Networks to 10.40.1.0/24, 10.250.1.0/30, 10.251.1.0/24, 10.50.1.0/30, and 10.50.2.0/30 J.

AS D. ABR 22. When adding a static route, you must always ensure that you add both the gateway and the interface.
false
23. Router A and B are both running as PPPoE servers on different broadcast domains of your network. It is possible to set Router A to use "/ppp secret" accounts from Router B to authenticate PPPoE customers. false
24. 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 A.
