2021-01-26 == Course : MTCNA-EN Name E-mail 1. PPPoE works only over Ethernet links. Is this true or false?TrueFalse2. When enabled in "Queues", which value indicates the maximum allowed data rate during "Bursting"?Max-limitBurst-limitLimit-burstBurst-max3. DHCP (Dynamic Host Configuration Protocol) permits you to:Discover other MikroTik routers on the networkAutomate the entire configuration process of a router once connected to the networkObtain (client) or assign (server) a MAC addressObtain (client) or assign (server) an IP address4. "IP pools" can be used by: (Select all that apply) DHCP Hotspot PPP Mangle Firewall Rules5. The "Firewall" has two sections; what are they?"Sources" and "Destinations""Matchers" and "Actions""Protocols" and "Ports""Matchers" and "Accept"6. What license level is required to operate a router as an access point?Any will do if you have the proper configurationLevel 3 minimalyLevel 5 minimalyAny except level 0 which is a demo licenseLevel 4 minimaly7. In order for a wireless client to be able to connect to an “AP”, it must support which rates?Basic-ratesData-ratesSupported-ratesMax-rates8. If you disable the firewall’s "Connection Tracking" feature, the following functions will also be disabled. Select all that apply. Connection-state P2P Simple Queues NAT9. It’s impossible to mix different types of interfaces under a bridge (such as Ethernet and Wireless). Is this true or false?FalseTrue10. A route in the routing table has the "DAC" flags. The "D" means:“Disabled”. The routing process will not use it until the administrator activates it“Discontinuous”. An error in IP addressing was found and has to be corrected by the network admin“Discovered”. It will disappear after 5 minutes“Dynamic”. It was added by the routing process and the administrator cannot remove it11. ARP is used to:Associate a TCP port to a MAC addressDetermine the IP address of the router to use when wanting to communicate with devices on other networksAssociate an IP address to a MAC addressLimit an application’s traffic12. Which of these tunneling protocols is considered safer?802.1XSSTPPPTPPPPoE13. The advantage of the PCQ “Queues” versus "Simple Queues" is: (Choose the best answer)The traffic always goes through the switch chip, making PCQ queues fasterYou can specify a firewall rule within PCQ parametersThere are more selection criteria, but the bandwidth is still shared by allThe allowed data rate is the same for each of the connections; it is not shared. So be careful not to allocate more bandwidth than available14. 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 1Port 515. Bridges work at which layer(s) of the OSI model?Layers 2 and 3Layers 3 and 4Layer 2 onlyLayer 3 only16. Access to a router without any IP configuration is possible using:WinBox LiteChromeImpossible. You must reinitialise the router using NetinstallMAC-WinBox17. "actions" in the firewall’s rules dictate:How remote management is madeThe criteria that determine the traffic that the rule will apply toHow the targeted traffic will be treatedThe time at which the rule applies18. 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.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 timeClients will all be limited to 200kbps, even if there is only one client on the networkThe 5 customers will share the bandwidth; in the worst of cases, each get 200kbpsCustomers will all get 1Mbps simultaneously. "Simple Queues" are not the best approach for this scenario19. An "AP" has 15 "Access Lists" entries. There are no "Access Lists" entries for customer "A". The interface’s "Default Authenticate" option is unchecked. What will happen to customer "A" when he’ll want to connect to the "AP"?He will never be able to connect to the wireless networkHe’ll be able to connect to the wireless network if the administrator accepts him by clicking on the "WDS Accept" buttonHe’ll get wireless connectivity if his data rates match those in "Basic-rates"He’ll be able to connect if his security settings match one that can be found "Security Profiles"20. When configuring a SSTP server, it is necessary to assign the service to a specific interface. Is this true or false?TrueFalse21. "PPP Secret" parameters override equivalent parameters "PPP Profiles". Is this true or false?FalseTrue22. A "Bridge" interface is:A software interface managed by the “switch chip"A software interface created via RouterOS menusA physical interface that must be purchased separately and installed in the routerA physical interface already in the router that has to be activated before use23. In the 802.11a/b/g/n protocols, the three channels that do not overlap are: (Pick all valid answers) 7 11 1 624. What unwanted side effect can you expect to see when you start “Snooper” on a live wireless network?All registered wireless clients will experience lost packets for the duration of the snooping.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.25. The firewall’s "Custom Chains" can be used to: (Select all that apply) Encrypt configuration files Simplify rules management Accelerate packet processing through the firewall Limit the use of physical resources (memory and CPU)Avez-vous des commentaires pour nous?
