9. A MikroTik system administrator implemented OSPF Routing protocol in the network. But realized that he has a static route on the routers. What can be done to make the static route work as a failover whenever the dynamic routing protocol fails.

 A. He should use "netwatch" to t rigger static routes whenever OSPF fails B. He should manually disable the static routes and enable them whenever OSPF fails C. Delete all static routes because there is no way for it to work with OSPF D. He should increase the administrative distance of the static route

10.  Consider the following diagram. We want to communicate from a device on LAN1 to a device on LAN2. Assuming that all necessary configurations are already included on R2, which of the following configurations in R1 would enable this communication?  A. /ip route add dst-address=192.168.0.0/24 gateway=192.168.0.1 B. /ip route add dst-address=0.0.0.0/0 gateway=Ether1 C. /ip route add dst-address=192.168.1.0/24 gateway=192.168.99.2 D. /ip route add dst-address=192.168.1.0/24 src-address=192.168.0.0/24 gateway=192.168.99.2 E. /ip route add dst-address=0.0.0.0/0 gateway=192.168.99.2

11.  New area OSPF \"area1\" has been created. What could be used as a valid area id?  A. 0.0.0.1 B. 0.0.0.0 C. 1.2.3.4

12.  In OSPF, router can become the DR (Designated Router) only when the priority on it\\\'s interface is set to a value of zero false

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

14. A network administrator has 2 vlans  /interface vlan add name=vlan1 vlan-id=101 interface=ether1 add name=vlan2 vlan-id=102 interface=vlan1 any packet sent over "vlan2" interface  A. will not go through at all because vlan1 will drop it B. will have two vlan tags added to ethernet header - "101" and "102" C. Wrong configuration because it is not possible to have a vlan over another vlan D. will have one vlan tag added to ethernet header - "102" E. will have one vlan tag added to ethernet header - "101"

15.  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?  A. 5.6.6.6 B. 5.5.5.5 C. the required route is not in the routing table D. both - half of the traffic will be routed through one gateway, half through the other 

16.  There can be more than one PPPoE server in a single broadcast domain: true

17. 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?
