1. 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 use
"netwatch" to trigger static routes whenever OSPF fails
C. He should manually disable
the static routes and enable them whenever OSPF fails
D. He should increase the
administrative distance of the static route
Penjelasan : untuk membuat
failover atau jalur cadangan seperti kasus diatas bisa dengan memberikan angka
distance yang lebih besar pada static routingnya karena router akan
memprioritaskan angka distance yang lebih kecil
2. /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?
A. 192.168.0.2
B. 192.168.0.3
C. 192.168.0.4
D. 192.168.0.1
3. RouterOS device has acquired an IP address from an ISP
using DHCP client. The same
router is used for assigning IP
addresses to local users using DHCP server, masquerade rule is
configured properly. Packets
that are coming from the ISP have TTL=1. Select correct
statement:
A. Router does not have access
to the Internet, but clients have
B. Neither router nor clients
have access to the Internet
C. All clients and router have
access to the Internet
D. Router has access to the
Internet, but clients do not
Penjelasan : sesuai namanya
TTL (TIME TO LIVE ) merupakan header yang menunjukan berapa lama paket itu bisa
bertahan, untuk setiap kali
mampir di sebuah roter nilainya akan berkurang satu, jadi apabila habis
ia tidak bisa terkirim ke tujuan selanjutnya, jadi klo TTL nya 1 ia tidak bisa
diteruskan lagi :D
4. You have a router with the following IP addresses:
ether1: 10.40.1.1/24

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

melakukan routing pada semua ip agar mereka bisa saling terhubung an bertukar
data
5. What is the administrative distance of OSPF routes?
A. 120
B. 110
C. 20
D. 10
Penjelasan :
– Connected routes : 0

– MME : 130
– iBGP: 200
6. Consider two geographically separate sites. At each
site, there is a RouterOS device.
Ether1 is connected to the LAN
and Ether2 is connected to the Internet.
An EoIP tunnel is created
between the two routers. And on both routers a Bridge interface
with the EoIP tunnel and Ether1
as ports.
10 users are connected at site
A and 30 users at site B. All users are configured to use a
DHCP server to obtain IP
address configuration.
What is the minimum number of
DHCP servers needed, (select correct configuration):
A. 1 DHCP Server: 1 server
on site B's router, on the Bridge interface.
B. 2 DHCP Servers: 1 server on
each router, on the LAN interface.
C. 1 DHCP Server: 1 server on
site A's router, on Ether2.
D. 2 DHCP Servers: 1 server on
each router, on the EoIP interface.
E. 2 DHCP Servers: 2 servers on
site B's router, one on the LAN interface and one on
the EoIP interface.
Penjelasan : diberikan DHCP
disana dengan tujuan client dari kedua router dapat menerima ip dari satu
sumber yang sama
7. When adding a static route, you must always ensure
that you add both the gateway and the
interface.
False
Penjelasan : untuk static
router kita cukup menambahkan salah satu saja interface atau ip gateway nya
8. When using routing option 'check-gateway=ping' after
how many timeouts is gateway
considered unreachable:
A. 1
B. 3
C. 4
D. 2
Penjelasan :
9. EOIP tunnels can not be bridged because they are not
true layer 2 tunnels.
False
Penjelasan : bisa kok
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?

gateway=Ether1
E. /ip route add dstaddress=
192.168.1.0/24
gateway=192.168.99.2
penjelasan : dari soal
diatas ada tiga jawaban
Jawaban yang A memakai default route, jawaban D sama cuman dia memeakai
interface utuk gatewaynya dan yang E ia memakai ip yang tepat untuk mengisi
dst.address, dan gatewaynya
11. /ip route can have DS flags simultaneously.
true
12. When using routing option 'check-gateway=ping' what is
the ICMP echo request interval
(in seconds)?
A. 60s
B. 20s
C. 30s
D.10s
Penjelasan :
13. In OSPF interface configuration what effect will a
“passive=yes” option have on a
specific interface ?
A. It will prevent all traffic
through that interface
B. It will prevent all OSPF
traffic through that interface
C. It will prevent routes
learned through the interface from being listed in the routing
table.
D. It will action a mirroring
of all routing upgrades to that interface
Penjelasan : passive
interface akan membatasi penerimaan dan pengiriman data pada interface tersebut
14. If one of two gateways is unreachable in an ECMP route
with check gateway set, 50% of
packets will be lost .
False
Penjelasan : apabila salah
satu interface tidak berfungsi maka interface satunya akan menjadi link
backupnya (failover)
15. There is no way to establish OSPF adjacency when the
link doesn't support multicast
traffic
False
Penjelasan : masih ada jalan
lain apabila link tidak support multicast seperti broadcast dan unicast
16. To assign specific traffic to a route – traffic must
be identified by a routing mark. Each
packet can only have one
routing mark.
true
penjelasan : routing mark
tidak bisa 2 hanya 1 saja
17. In case it is not administratively defined, how is
OSPF Router ID determined?
A. Random number.
B. Random IP addresses from any
interface included in OSPF.
C. The highest IP address of
any interface on the router.
D. The lowest IP address of any
interface included in OSPF.
E. Random IP address from any
interface on the router.
F. The lowest IP address of any
interface on the router.
G. The highest IP address of
any interface included in OSPF.
Penjelasan : untuk percobaan
coba kita masukan ip 0.0.0.0 pada id nya maka akan muncul ip yang terbesar,
biasanya diisi dengan ip loopback
18. It is possible to create a configuration where VLAN
and PPTP interfaces are bridged
together.
False
Penjelasan: jika pptp
dilakukan masih bisa di ppptp tapi klo di vlan gk bisa karena sudah di bridge
19. Which routing table is used to apply recursive routing
at MikroTik RouterOS
A. It is not possible
B. It is possible in all the
routing tables installed in a router
C. It is only possible in
the main routing table
D. It is only possible on the
x86 platform
20. Which static-route rule will have priority for
destination 192.168.0.18?
A.
dst-address=192.168.0.0/24 gateway=192.168.3.1 distance=1
B. dst-address=192.168.0.0/26
gateway=192.168.1.1 distance=3
C.
dst-address=192.168.0.0/28 gateway=192.168.4.1 distance=5
D. dst-address=192.168.0.0/26
gateway=192.168.2.1 distance=2
E. dst-address=192.168.0.0/28
gateway=192.168.3.1 distance=1
Penjelasan : yang di
prioritaskan adalah yang memiliki distance paling kecil, tapi tetap perlu
diperhatikan ip dan netmask nya
21. 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
Penjelasan : tidak bisa
karena broadcast domain yang berbeda
22. OSPF area ID does not need to be unique within the AS.
False
Penjelasan : area id dlam
sebuah mesti unik dan tidak ada yang boleh sama satu dengan yang lainnya

expecting what kind of address for an
answer?
A. 802.11g
B. MAC Address
C. IP address

Penjelasan : arpbertugas
untuk mencatat mac address
24. The correct order for PPPOE discovery stage is
A. Initialization, Offer,
Request and Session confirmation
B. Request, Offer,
Initialization and Session confirmation
C. Request, Initialization,
Session confirmation and Offer
D. Initialization, Session
confirmation, Request and Offer
Penjelasan :
- initialization = mencari
dimana pppoe server
- offer = pppoe menjawab
proses sebelumnya dengan memberikan identitasnya
- request = konfirmasi dari
sisi client , sekarang ia sudah bisa menghubungi mac address si server
- session confirmation =
server memberikan id kepada client
