Static Routing
3. MikroTik router needs to forward IP-packet targeted to 11.12.4.5. Router routing table has 3 routes,
• 1. dst-address=11.12.4.0/24, distance=10, gateway=1.1.1.1
• 2. dst-address=11.12.4.0/28, distance=20, gateway=1.1.1.2.
• 3. dst-address=0.0.0.0/0, distance=1,
gateway=1.1.1.254. Which of the gateways will router select?
A. 2 B. 3 C. Nowhere. D. Host will get "destination
host unreachable". E. 1
5. Consider the following output from the command "/ip address print":

necessary configurations are already included on R2, which of the following configurations in R1 would enable this
communication?

dst-address=192.168.1.0/24 gateway=192.168.99.2 C. /ip route add
dst-address=192.168.0.0/24 gateway=192.168.0.1 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
24. There are four routes in the routing table. Host 10.10.10.10 becomes
unreachable.
• 1 dst-addr=0.0.0.0/0 gateway=11.11.11.11
• 2 dst-addr=20.20.20.0/24 gateway=10.10.10.10 check-gateway=ping
• 3 dst-addr=30.30.30.0/24 gateway=10.10.10.10
• 4 dst-addr=30.30.30.0/25 gateway=13.13.13.13 check-gateway=ping
27. When creating a route, it is possible to specify the gateway to a network even if the gateway is not directly connected by using
recursive next-hop resolving from an existing route.
(TRUE/FALSE)
28. Routing table has several routes with the same gateway. If 'check-gateway' is enabled for one of the routes, and the
gateway
becomes unreachable, then
A. only this one route would become inactive B. all routes with the same gateway would become inactive C.
the 'check-gateway' feature would not work at all, since the same gateway is used for more than one route
OSPF
1. Only OSPF routes distributed as "external" can be filtered with routing filters (TRUE/FALSE)
3. 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 trigger static routes whenever OSPF fails 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. Delete all static routes
because there is no way for it to work with OSPF
4. An OSPF area consists of 15 routers connected in 6 different broadcast networks. How many Designated routers there will be in
the
area? A. 6 B.
1 C. 0 D. 15
5. Which is the correct way to set a comment in a OSPF dynamic route: PROPERTY

MikroTik Certification Exam Sample Questions P
6. What is the minimum configuration a network administrator needs to do on a MikroTik router to enable OSPF?
A. Nothing; OSPF instance can run with no configuration B. Both
interface and network must be added to OSPF configuration C. Add an
interface to OSPF interface configuration
7. In OSPF settings, the NBMA Neighbor setting can be used to improve the stability of OSPF across wireless links.
(TRUE/FALSE)
8. It is possible to have OSPF and BGP configured on the same router? (YES/NO)
9. In this ospf network (see diagram), we want to re-distribute routes from R5 to the R3 router. Where do I have to create a virtual
link? A. There is no need for a virtual-link B.

?

It will action a mirroring of all routing upgrades to that interface C. It will prevent all OSPF
traffic through that interface D. It will prevent all traffic through that interface
VLAN
1. VLAN is an implementation of the 802.1Q VLAN protocol by the MikroTik RouterOS. It allows you to have multiple Virtual LANs on
a single ethernet or wireless interface, giving the ability to segregate LANs efficiently. How many different vlans are possible on

one C. 63 D.
4095

to
use "/ppp secret" accounts from Router B to authenticate PPPoE customers?
(YES/NO)
2. To route two private networks together over a public routed network (there are multiple hops between the gateway routers of the

if
there is a router between the customer and that PPPoE server.
(TRUE/FALSE)
9. Settings in /ppp secret user database override corresponding /ppp profile settings. (TRUE/FALSE)
