    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
