  Certification example test
  1. Which computers would be able to communicate directly (without any routers involved)
  10.10.0.17/22 and 10.10.1.30/23
  192.168.17.15/29 and 192.168.17.20/28
  10.5.5.1/24 and 10.5.5.100/25
  192.168.0.5/26 and 192.168.0.100

  2. In MikroTik RouterOS, Layer-3 communication between 2 hosts can be achieved by using an address subnet of:
  /29
  /32
  /31
  /30

  3. MAC layer by OSI model is also known as
  Layer 2
  Layer 1
  Layer 3
  Layer 6
  Layer 7

  4. The basic unit of a physical network (OSI Layer 1) is the:
  Byte
  Frame
  Header
  Bit

  5. If ARP=reply-only is configured on an interface, what will this interface do
  Add new IP addresses in /ip arp list
  Accept all IP/MAC combinations listed in /ip arp as static entries
  Accept all IP addresses listed in /ip arp as static entries
  Accept all MAC-addresses listed in /ip arp as static entries
  Add new MAC addresses in /ip arp list

  6. Which of the following protocols / port s are used for SNMP. (Simple Network Managemnt Protocol)
  UDP 161
  UDP 162
  TCP 123
  TCP 161
  TCP 25
  TCP 162

  7. How many IP addresses can one find in the header of an IP packet?
  1
  2
  4
  3

  8. A PC with IP 192.168.1.2 can access internet, and static ARP has been set for that IP address on gateway. When the PC Ethernet card failed, the user change it with a new card and set the same IP for it.
  What else should be done?
  Old static ARP entry on gateway has to be updated for the new card
  Another IP has to be added for Internet access
  Nothing - it will work as before
  MAC-address of the new card has to be changed to MAC address of old card

  9. Which of the following is NOT a valid MAC Address?
  80:GF:AA:67:13:5D
  88:0C:00:99:5F:EF
  95:B5:DD:EE:78:8A
  13:16:86:53:89:43
  EA:BA:AA:EE:FF:CB

  10. Choose all valid hosts address range for subnet 15.242.55.62/27
  15.242.55.31-15.242.55.62
  15.242.55.33-15.242.55.63
  15.242.55.33-15.242.55.62
  15.242.55.32-15.242.55.63

  11. Select which of the following are 'Public IP addresses':
  172.28.73.21
  192.168.0.1
  172.168.254.2
  10.110.50.37
  11.63.72.21

  12. A network ready device is directly connected to a MikroTik RouterBOARD 750 with a correct U.T.P. RJ45 functioning cable. The device is configured with an IPv4 address of 192.168.100.70 using a subnet mask of 255.255.255.252. What will be a valid IPv4 address for the RouterBOARD 750 for a successful connection to the device?

  192.168.100.68/255.255.255.252
  192.168.100.69/255.255.255.252
  192.168.100.71/255.255.255.252
  192.168.100.70/255.255.255.252

  13. What is term for the hardware coded address found on an interface?
  MAC Address
  Interface Address
  IP Address
  FQDN Address

  14. What protocol does ping use?
  TCP
  ICMP
  UDP
  ARP

  15. Select valid MAC-address
  AEC8:21F1:AA44:54FF:1111:DDAE:0212:1201
  00:00:5E:80:EE:B0
  G2:60:CF:21:99:H0
  192.168.0.0/16

  16. Collisions are possible in full-duplex Ethernet networks

  17. The network address is
  The first address of the subnet
  The last address of the subnet
  The first usable address of the subnet

  18. You have a router with configuration
  - Public IP :202.168.125.45/24
  - Default gateway:202.168.125.1
  - DNS server: 248.115.148.136, 248.115.148.137
  - Local IP: 192.168.2.1/24

  Mark the correct configuration on client PC to access to the Internet
  IP:192.168.1.223/24 gateway:248.115.148.136
  IP:192.168.2.2/24 gateway:202.168.125.45
  IP:192.168.0.1/24 gateway:192.168.2.1
  IP:192.168.2.115/24 gateway: 192.168.2.1
  IP:192.168.2.253/24 gateway:202.168.0.1
