Which two statements characterize wirelessnetwork security? (Choose two.)A rogue access point represents a security risk for the localnetwork.Wireless networks offer the same security features as wirednetworks.Using encryption prevents unauthorized clients fromassociating with an access point.An attacker needs physical access to at least one networkdevice to launch an attack.With SSID broadcast disabled, an attacker must sniff theSSID before being able to connect.12.

What will a wireless client transmit to discover theavailable WLAN networks?beaconpasswordprobe requestassociation request15. In a WLAN network, why should wireless accesspoints be implemented with each access point using adifferent channel?to keep users segregated on separate subnetsto control the amount of bandwidth that is utilizedto keep signals from interfering with each otherto keep traffic secure16.
What purpose does authentication serve in aWLAN?converts clear text data before transmissionindicates which channel the data should flow ondetermines that the correct host is utilizing the networkallows the host to choose which channel to use17. What occurs when a rogue access point is added toa WLAN?Authorized access points can transmit excess traffic to rogueaccess points to help alleviate congestion.Unauthorized users can gain access to internal servers, thuscausing a security hole.All traffic that uses the same channel as the rogue accesspoint will be encrypted.All traffic that uses the same channel as the rogue accesspoint will be required to authenticate.18.
What procedure can prevent man-in-the-middleattacks?Force all devices on a WLAN to authenticate and monitor forany unknown devices.Enable access points to send an SSID to each devicewanting to use the network.Configure MAC filtering on all authorized access points.Disable SSID broadcasts.http://cisco-ccna-certifications.blogspot.com/2008/08/ccna-3module-7.html[10/29/2008 3:25:33 PM]CISCO CCNA Certifications: CCNA 3:Module 719.

Характеристики
Тип файла PDF
PDF-формат наиболее широко используется для просмотра любого типа файлов на любом устройстве. В него можно сохранить документ, таблицы, презентацию, текст, чертежи, вычисления, графики и всё остальное, что можно показать на экране любого устройства. Именно его лучше всего использовать для печати.
Например, если Вам нужно распечатать чертёж из автокада, Вы сохраните чертёж на флешку, но будет ли автокад в пункте печати? А если будет, то нужная версия с нужными библиотеками? Именно для этого и нужен формат PDF - в нём точно будет показано верно вне зависимости от того, в какой программе создали PDF-файл и есть ли нужная программа для его просмотра.
