 54.  A.  The command 

logging buffered 1 will configure the logs stored in RAM, which 

is buffered to a severity of 1. This command will include severity levels 1 and 0. The 

command 

logging 1 is incorrect. The command logging buffered 2 will set the 

logging level to critical events. The command 

logging 2 is incorrect.

 55.  C.  The command 

show history will show the last commands typed, which are kept 

in the buffer. The history normally includes the last 10 commands. The command 

show 

commands is incorrect. The command show log is incorrect as it will display the logs. The 

command 

show buffer is incorrect.

 56.  B.  Line protocol up/down messages are logged to the notifications (5) severity level. This 

can be determined by looking up the 5 that appears after the affected component of line 

protocol in the syslog severity chart. For example, 

%LINEPROTO-5-UPDOWN specifies the 

severity level of 5 for the line protocol. All of the other options are incorrect.

 57.  C.  The command 

show processes will display the utilization of the CPU. The first line 

of the output is broken down by 5 second utilization, 1 minute utilization, and 5 minute 

utilization. The command 

show cpu is incorrect. The command show cpu-stats is 

incorrect. The command 

show environment cpu is incorrect.

 58.  A.  The command 

logging buffered will direct buffering of log messages to RAM. 

This command can be undone by using the 

no directive in front of logging buffered. 

The command must be entered in global configuration mode. The command 

logging 

internal is incorrect. The command logging ram is incorrect. The command logging 

console is incorrect.

 59.  B.  By default, all syslog messages are sent to the console of the router or switch. It is 

recommended to configure a syslog server, because once the router or switch is powered 

off, the information is lost. Syslog messages are never broadcast, but they can be directed 

to a syslog server. Syslog messages can only be sent to the connected TTY if the command 

terminal monitor is entered. Syslog messages cannot be sent to NVRAM.

 60.  D.  The default syslog facility level is debugging (7). All debugging messages are logged to 

the internal buffer by default. Notification (5) is not the default level for syslog logging. 

Informational (6) is not the default level for syslog logging. Warning (4) is not the default 

level for syslog logging.

 61.  A.  The command 

show dhcp lease will help you verify the IP address configured on 

the router, the DHCP server that served the lease, and the lease time in seconds. The 

command 

show ip dhcp lease is incorrect. The command show ip lease is incorrect. 

The command 

show ip interface is incorrect.

 62.  C.  The DHCP Offer packet is a broadcast packet from the DHCP server to the DHCP 

client. The layer 3 packet and layer 2 frame are both broadcasts. The layer 3 destination to 

the DHCP client is not a unicast. The layer 2 destination of the Offer packet is a broadcast 

and therefore not the destination MAC address of the client. Link-local addressing is not 

used for DHCP.
