E. The accuracy of the data to be analyzed is improved.
B. CPU and memory utilization are reduced.
C. The number of packets to be analyzed are reduced.
A network administrator is implementing a routing configuration change and enables routing debugs to track routing behavior during the change. The logging output on the terminal is interrupting the command typing process. Which two actions can the network administrator take to minimize the possibility of typing commands incorrectly? (Choose two.)
A. Configure the logging synchronous global configuration command.
B. Configure the logging synchronous command under the vty.
C. Increase the number of lines on the screen using the terminal length command.
D. Configure the logging delimiter feature.
E. Press the TAB key to reprint the command in a new line.
B. Configure the logging synchronous command under the vty.
E. Press the TAB key to reprint the command in a new line.
