Upon deleting an IOS image file from flash, an execution of show flash shows the file still in flash, with a ‘D’ preceding it (as shown in the exhibit). What step must be taken in order to remove the file completely?

A subscriber complains that his DSL rates are slower than the service he
ordered. The customer ordered ADSL at 1 mpbs downstream and 256 kbps upstream, but the maximum bitrate observed during file downloads is 100 kbps downstream. Of the following four choices, which is clearly the most appropriate information needed to begin troubleshooting the problem?

A DSL line status report shows a high number of corrected and uncorrected errors. The line is configured at 4 milliseconds interleave delay and 4 FEC check-bytes. To reduce the number of uncorrected errors without a detailed analysis of whether the errors are continuous or “bursty”, which of the following should provide improved error correction?

Three of the following are common symptoms of a bridge tap (“half tap”) on
a DSL line. Which three are symptoms that result from placing a bride tap on a DSL line?

A DSLAM is using Reed-Solomon forward error correction on a DMT DSL line. The DSL service is using TCP/IP over ATM over DSL. A high number of upstream RS uncorrected errors are occurring on the DSL line, as reported by the DSLAM in the following status message:DSL Statistics:Init Events: 2Transmitted Superframes: near end: 93681573 far end: 0Received Superframes:
near end: 93516422 far end: 0Corrected Superframes: near end: 142631 far end: 31571Uncorrected Superframes: near end: 191 far end: 1LOS Events: near end: 0 far end: 0LOF/RFI Events: near end: 0 far end: 0ES Events: near end: 5 far end: 1What is the result of the uncorrected errors?

The TCP PUSH flag indicates:

Host 1 and Host 2 are on Ethernet LANs in different buildings. A serial line is installed between two Cisco routers using Cisco HDLC serial line encapsulation. Routers A and B are configured to route IP traffic. Host 1 sends a packet to Host 2. What is the destination MAC address of the packet on Host’s 1 Ethernet?

What is Forwarding Equivalence Class assignment NOT likelyto be based upon?
