16. 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 OSPF networks, to 10.50.1.0/30, 10.50.2.0/30
B. set distribute-state=yes
C. set distribute-default=always-type-1
D. Set Distribute-Connected=yes
E. Set OPSF networks to 10.0.0.0/8 only
F. Set Ethernet 2 and 3 to passive mode
G. Set OSPF networks to 0.0.0.0/0
H. 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
I. Set Ethernet 1, 2, and 3 to passive mode

A. 30%
B. 25%
C. 50%

21. 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. Delete all static routes because there is no way for it to work with OSPF
B. He should manually disable the static routes and enable them whenever OSPF fails
C. He should increase the administrative distance of the static route
D. He should use "netwatch" to trigger static routes whenever OSPF fails
22. In OSPF interface configuration what effect will a "passive=yes" option have on a specific interface ?

B. It will prevent all OSPF traffic through that interface
C. It will action a mirroring of all routing upgrades to that interface

23. If 'check-gateway' is enabled for an ECMP route and one of the gateways is unreachable, then:
A. The unreachable gateway is not going be used in Round Robin algorithm.
B. ECMP is going to send packets to all gateways even if one is unreachable.
C. The ECMP route becomes inactive.
24. 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
