2020-10-24 == Course : MTCNA-EN Name E-mail 1. Name two parameters that the “Country Code” parameter regulates. Bands and antenna gain. Maximum transmission power and jitter in VoIP communications. Frequencies and maximum transmission power. Frequencies and acceptable channel overlap.2. Bridges work at which layer(s) of the OSI model? Layer 2 only Layer 3 only Layers 3 and 4 Layers 2 and 33. The "Firewall" has two sections; what are they? "Matchers" and "Accept" "Matchers" and "Actions" "Sources" and "Destinations" "Protocols" and "Ports"4. In "Simples Queues", what is the sampling rate of a client’s traffic to determine if he can “burst”? "Burst-limit" / "Max-limit" in seconds Half of "Burst-time" in seconds 1/16 of "Burst-time" in seconds Every 1/100th of a second, regardless of other parameters entered5. ARP is used to: Limit an application’s traffic Associate a TCP port to a MAC address Determine the IP address of the router to use when wanting to communicate with devices on other networks Associate an IP address to a MAC address6. What license level is required to operate a router as an access point? Level 4 minimaly Any will do if you have the proper configuration Level 5 minimaly Any except level 0 which is a demo license Level 3 minimaly7. The wireless protocol can operate in the 2.4GHz frequency band as well as in the 5GHz frequency band is: 802.11n 802.11ac 802.11a 802.11g8. You have deployed a router that will act as a wireless client (CPE). Although you have created “Access Lists” to indicate to which APs you wish to connect to, you have, on occasion, gotten connected to Aps you shouldn’t have. What should you do? Validate that the ROS version you are using supports 802.11. Uncheck Defaut Authentication at the interface level. Use “Connect Lists” for your CPE, not “Access Lists”. Check the SSID and security profile in your access lists.9. Static routing reacts very well and quickly to network failures. Is this true or false? True False10. Access to MikroTik routers can be done the following ways: (Select all valid responses) Telnet / SSH A web browser (Browser) Console Port WinBox11. What "Simple Queue" parameter is used to specify the maximum data rate allowed by "Target"? Burst-limit Limit-at Max-limit Top-limit12. Access to a router without any IP configuration is possible using: Impossible. You must reinitialise the router using Netinstall Chrome WinBox Lite MAC-WinBox13. When configuring a SSTP server, it is necessary to assign the service to a specific interface. Is this true or false? False True14. Select two ways you can upgrade ROS. While in the “System > Packages” window, click on "Check For Updates" Returning to MikroTik for a factory upgrade Manually downloading the required files from MikroTik's download page and copying them over to the router ROS cannot be upgraded on RouterBOARDs, only in X86 architectures15. To protect your devices from traffic coming from the Internet, what basic firewall chain will you use? Output Input Forward Any chain will do16. It’s impossible to mix different types of interfaces under a bridge (such as Ethernet and Wireless). Is this true or false? False True17. You have RB751 and RB951 routers that need upgrading. You have chosen to use Netinstall. In which port will you plug your computer before you start? Port 5 Port 2 Any port will do as long as you configure it as a DHCP-client Port 118. You have a network with ten routers. Router R10 is connected to the network through a single interface. Its IP address is 10.1.1.1/30 and the address of its neighbor is 10.1.1.2/30. What would be the command to enable proper routing on R10? /ip route add destination=all nexthop=10.1.1.2 /ip route add destination=default gateway=10.1.1.2 /ip route add gateway=10.1.1.2 /ip route add nexthop=10.1.1.219. You are using a "Simple Queue" to limit the use of bandwidth on a 1Mbps link. You have 5 clients on your network. Choose the statement that best summarizes what might happen. Customers will all get 1Mbps simultaneously. "Simple Queues" are not the best approach for this scenario The 5 customers will share the bandwidth; in the worst of cases, each gets 200kbps. But, with the bursting, they may go up to 300Kbps for short periods of time The 5 customers will share the bandwidth; in the worst of cases, each get 200kbps Clients will all be limited to 200kbps, even if there is only one client on the network20. When creating a "Simple Queue", which parameter must be specified? Burst-limit Destination Target Max-limit21. "PPP Secret" parameters override equivalent parameters "PPP Profiles". Is this true or false? True False22. There is an automated way of creating a DHCP server by answering a few questions. Is this true or false? False True23. A route in the routing table has the "DAC" flags. This means that: It's a static route The route was added by the routing process after being discovered through OSPF The route was added by the routing process because a local interface has an IP address and is up and running The route was added by the routing process after being discovered through RIP24. The advantage of the PCQ “Queues” versus "Simple Queues" is: (Choose the best answer) You can specify a firewall rule within PCQ parameters The allowed data rate is the same for each of the connections; it is not shared. So be careful not to allocate more bandwidth than available The traffic always goes through the switch chip, making PCQ queues faster There are more selection criteria, but the bandwidth is still shared by all25. An "IP Pool" is already configured to assign addresses between 192.168.5.50 and 192.168.5.99. To add a range of addresses between 192.168.5.150 and 192.168.5.199 in the same "IP Pool", the syntax is: set 0 ranges=192.168.5.50-192.168.5.99,192.168.5.150-192.168.5.199 add 0 ranges=192.168.5.150-192.168.5.199 add 0 ranges=192.168.5.50-192.168.5.99,192.168.5.150-192.168.5.199 set 0 ranges=192.168.5.150-192.168.5.199Avez-vous des commentaires pour nous?
