Choose the statement that best summarizes what might happen.Clients will all be limited to 200kbps, even if there is only one client on the networkCustomers will all get 1Mbps simultaneously. "Simple Queues" are not the best approach for this scenarioThe 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 timeThe 5 customers will share the bandwidth; in the worst of cases, each get 200kbps2. Static routing reacts very well and quickly to network failures. Is this true or false?TrueFalse3. Access to a router without any IP configuration is possible using:ChromeImpossible. You must reinitialise the router using NetinstallMAC-WinBoxWinBox Lite4. As far as packet throughput is concerned, using a bridge interface is as quick and efficient as using the switch chip. Is this true or false?FalseTrue5. "actions" in the firewall’s rules dictate:The criteria that determine the traffic that the rule will apply toHow remote management is madeHow the targeted traffic will be treatedThe time at which the rule applies6. In order for a wireless client to be able to connect to an “AP”, it must support which rates?Supported-ratesMax-ratesBasic-ratesData-rates7. ARP is used to:Determine the IP address of the router to use when wanting to communicate with devices on other networksAssociate a TCP port to a MAC addressAssociate an IP address to a MAC addressLimit an application’s traffic8. Access to MikroTik routers can be done the following ways: (Select all valid responses) Telnet / SSH WinBox A web browser (Browser) Console Port9. What "Simple Queue" parameter is used to specify the maximum data rate allowed by "Target"?Max-limitTop-limitLimit-atBurst-limit10. If you disable the firewall’s "Connection Tracking" feature, the following functions will also be disabled. Select all that apply. Simple Queues NAT Connection-state P2P11. The wireless protocol can operate in the 2.4GHz frequency band as well as in the 5GHz frequency band is:802.11a802.11ac802.11g802.11n12. To protect your devices from traffic coming from the Internet, what basic firewall chain will you use?OutputAny chain will doInputForward13. 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 2Any port will do as long as you configure it as a DHCP-clientPort 5Port 114. 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=192.168.5.50-192.168.5.99,192.168.5.150-192.168.5.199add 0 ranges=192.168.5.50-192.168.5.99,192.168.5.150-192.168.5.199set 0 ranges=192.168.5.150-192.168.5.199add 0 ranges=192.168.5.150-192.168.5.19915. Which of these tunneling protocols is considered safer?802.1XPPPoEPPTPSSTP16. "IP pools" can be used by: (Select all that apply) DHCP Mangle Firewall Rules PPP Hotspot17. The three basic firewall chains are:Input, output, forwardInbound, outbound, throughSrc-traffic, Dst-traffic, All-trafficMatchers, Actions, Queues18. The advantage of the PCQ “Queues” versus "Simple Queues" is: (Choose the best answer)There are more selection criteria, but the bandwidth is still shared by allThe traffic always goes through the switch chip, making PCQ queues fasterYou can specify a firewall rule within PCQ parametersThe allowed data rate is the same for each of the connections; it is not shared. So be careful not to allocate more bandwidth than available19. It’s impossible to mix different types of interfaces under a bridge (such as Ethernet and Wireless). Is this true or false?TrueFalse20. In the 802.11a/b/g/n protocols, the three channels that do not overlap are: (Pick all valid answers) 11 7 6 121. Name two parameters that the “Country Code” parameter regulates.Frequencies and acceptable channel overlap.Frequencies and maximum transmission power.Bands and antenna gain.Maximum transmission power and jitter in VoIP communications.22. 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?Use “Connect Lists” for your CPE, not “Access Lists”.Validate that the ROS version you are using supports 802.11.Uncheck Defaut Authentication at the interface level.Check the SSID and security profile in your access lists.23. When enabled in "Queues", which value indicates the maximum allowed data rate during "Bursting"?Burst-limitMax-limitBurst-maxLimit-burst24. There is an automated way of creating a DHCP server by answering a few questions. Is this true or false?TrueFalse25. What unwanted side effect can you expect to see when you start “Snooper” on a live wireless network?Nothing bad has ever been reported when snooping a wireless network.All registered wireless clients will lose connectivity for the duration of the snooping.All registered wireless clients will operate at half speed for the duration of the snooping.All registered wireless clients will experience lost packets for the duration of the snooping.Avez-vous des commentaires pour nous?
