2021-07-23 == Course : MTCNA-EN Name E-mail 1. 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 5Port 1Port 2Any port will do as long as you configure it as a DHCP-client2. A static route can be used in which of the following situations?Only when the router has enough memory and a powerful CPU since static routes can have a big impact on those resourcesNone of those answers since ROS does not support static routingA small network of one or two routers that will never grow and that only has one possible way to reach "anything" elseTwo implement layer2 security when your Internet service provider cannot insure protection against viruses3. To protect your devices from traffic coming from the Internet, what basic firewall chain will you use?OutputForwardInputAny chain will do4. To create a "Custom Chain", you must have: (Choose the best answer)At least two "Matchers" and the “Jump” actionAt least one "Matcher" and one "Action"At least one "Matcher" and the “Jump” actionThe matcher "Protocol = icmp" and the “Jump” action5. To protect your router from traffic aimed at it, what basic firewall chain will you use?ForwardInputOutputAny chain will do6. When creating a "Simple Queue", which parameter must be specified?TargetMax-limitDestinationBurst-limit7. The firewall’s "Custom Chains" can be used to: (Select all that apply) Simplify rules management Accelerate packet processing through the firewall Encrypt configuration files Limit the use of physical resources (memory and CPU)8. You support an old network with 50 computers on an old hub. What impact would replacing the hub with a switch having "full duplex" ports have?Full duplex ports make data rates 4 times faster than on a hubAs each switch port is a collision domain, it eliminates collisions between computer data transfers and improves network performanceIt is now possible to deploy a firewallAs each switch port is a broadcast domain, computers no longer hear the other computers broadcasts, thus reducing the unnecessary burden on computers9. "PPP Secret" parameters override equivalent parameters "PPP Profiles". Is this true or false?TrueFalse10. The "Firewall" has two sections; what are they?"Matchers" and "Accept""Matchers" and "Actions""Protocols" and "Ports""Sources" and "Destinations"11. A "Bridge" interface is:A physical interface that must be purchased separately and installed in the routerA physical interface already in the router that has to be activated before useA software interface managed by the “switch chip"A software interface created via RouterOS menus12. A route in the routing table has the "DAC" flags. The "D" means:“Discontinuous”. An error in IP addressing was found and has to be corrected by the network admin“Dynamic”. It was added by the routing process and the administrator cannot remove it“Disabled”. The routing process will not use it until the administrator activates it“Discovered”. It will disappear after 5 minutes13. Name two parameters that the “Country Code” parameter regulates.Frequencies and maximum transmission power.Bands and antenna gain.Maximum transmission power and jitter in VoIP communications.Frequencies and acceptable channel overlap.14. Your colleague would like to access the office server while meeting his customers. He wants you to create a PPPoE server on your router. As for him, he’ll create a PPPoE client on his laptop and connect it to his mobile phone to gain access to the Internet. What do you tell him?To make this work, he’ll have to use IP v4 as PPPoE does not support IP v6 yetIn addition to enabling PPPoE, you must create a PPP account on your router. That's allNo problem to do itIt will not work because PPPoE is a layer 2 protocol. It must be on the same subnet as the router for it to work15. The three basic firewall chains are:Matchers, Actions, QueuesInput, output, forwardSrc-traffic, Dst-traffic, All-trafficInbound, outbound, through16. The wireless protocol can operate in the 2.4GHz frequency band as well as in the 5GHz frequency band is:802.11ac802.11g802.11a802.11n17. In order for a wireless client to be able to connect to an “AP”, it must support which rates?Supported-ratesBasic-ratesMax-ratesData-rates18. Static routing reacts very well and quickly to network failures. Is this true or false?FalseTrue19. 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 allYou 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 availableThe traffic always goes through the switch chip, making PCQ queues faster20. 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?TrueFalse21. Access to MikroTik routers can be done the following ways: (Select all valid responses) A web browser (Browser) WinBox Telnet / SSH Console Port22. A route in the routing table has the "DAC" flags. This means that:The route was added by the routing process after being discovered through RIPThe route was added by the routing process after being discovered through OSPFThe route was added by the routing process because a local interface has an IP address and is up and runningIt's a static route23. PPPoE works only over Ethernet links. Is this true or false?FalseTrue24. 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=192.168.5.50-192.168.5.99,192.168.5.150-192.168.5.199set 0 ranges=192.168.5.150-192.168.5.199add 0 ranges=192.168.5.50-192.168.5.99,192.168.5.150-192.168.5.199add 0 ranges=192.168.5.150-192.168.5.19925. What "Simple Queue" parameter is used to specify the maximum data rate allowed by "Target"?Limit-atBurst-limitTop-limitMax-limitAvez-vous des commentaires pour nous? Do you have comments for us?
