(Choose two.)    The software is version 12.1, 4th revision.    The IOS is for the Cisco 2600 series hardware platform. 4. Refer to the exhibit. What is accomplished when both commands are configured on the router?    The commands disable the services such as echo, discard, and chargen on the router to prevent security vulnerabilities. 5. Which two conditions should the network administrator verify

http://p4s-ccna.blogspot.com http://testccna-4u.blogspot.com 1. Refer to the exhibit. An administrator documented the output of a CAM table from an Ethernet switch as shown. What action will the switch take when it receives the frame shown at the bottom of the exhibit? discard the frame forward the frame out port 2 forward the frame out port 3 forward the frame out all ports ***forward the frame out all ports except port 3 add station 00-00-3D-1F-11-05 to port 2 in the forwarding table 2.Refer to the exhibit. What does the term DYNAMIC indicate in the output that is shown? This entry can only be removed from the MAC address table by a network administrator. When forwarding a frame to the device with address 0060.5c5b.cd23,the switch does not have to perform a lookup to determine Only the device with MAC address 0060.5c5b.cd23 will be allowed to connect to port Fa0/18 ***The switch learned this MAC address from the source address in a frame received on Fa0/18 3. A new switch is to be a

1. Which best describes the benefit of using Frame Relay as opposed to a leased line or ISDN service?   Customers only pay for the local loop and the bandwidth they purchase from the network provider. 2. Which statement about Frame Relay subinterfaces is correct?    Point-to-point subinterfaces act like leased lines and eliminate split-horizon routing issues. 3. What best describes the use of a data-link connection identifier (DLCI)?   locally significant address used to identify a virtual circuit 4.
