Chapter 33 - Device Management Protocols Flashcards
What level of logging to the console is the default for a Cisco device?
a. Informational
b. Errors
c. Warnings
d. Debugging
D.
By default, all message levels are logged to the console on a Cisco device. To do so, IOS uses logging level 7 (debugging), which causes IOS to send severity level 7, and levels below 7, to the console. All the incorrect answers list levels below level 7.
What command limits the messages sent to a syslog server to levels 4 through 0?
a. logging trap 0-4
b. logging trap 0,1,2,3,4
c. logging trap 4
d. logging trap through 4
C.
The logging trap 4 command limits those messages sent to a syslog server (configured with the logging host ip-address command) to levels 4 and below, thus 0 through 4.
Which of the following is accurate about the NTP client function on a Cisco router?
a. The client synchronizes its time-of-day clock based on the NTP server.
b. It counts CPU cycles of the local router CPU to more accurately keep time.
c. The client synchronizes its serial line clock rate based on the NTP server.
d. The client must be connected to the same subnet as an NTP server.
A.
NTP uses protocol messages between clients and servers so that the clients can adjust their time-of-day clock to match the server. NTP is totally unrelated to serial line clocking. It also does not count CPU cycles, instead relying on messages from the NTP server. Also, the client defines the IP address of the server and does not have to be in the same subnet.
Router R2 uses NTP in client/server mode. Which of the following correctly describes the use of the NTP configuration commands on Router R2?
(Choose two answers.)
a. The ntp server command enables R2’s NTP server function.
b. The ntp server command makes R2 an NTP client and references a server.
c. The ntp master command enables R2’s NTP server function.
d. The ntp master command enables R2’s client function and references the server.
B and C.
A router acting in client/server mode acts as both a client, synchronizing its own time with another server, and in server mode, supplying time information to other NTP clients. The ntp server command enables the client function, pointing at some other server, while the ntp master command enables the NTP server function on that local router.
Imagine that a switch connects through an Ethernet cable to a router, and the router’s host name is Hannah. Which of the following commands could tell you information about the IOS version on Hannah without establishing a Telnet connection to Hannah?
(Choose two answers.)
a. show neighbors Hannah
b. show cdp
c. show cdp neighbors
d. show cdp neighbors Hannah
e. show cdp entry Hannah
f. show cdp neighbors detail
E and F.
CDP discovers information about neighbors. show cdp gives you several options that display more or less information, depending on the parameters used.
A switch is cabled to a router whose host name is Hannah. Which of the following LLDP commands could identify Hannah’s model of hardware?
(Choose two answers.)
a. show neighbors
b. show neighbors Hannah
c. show lldp
d. show lldp interface
e. show lldp neighbors
f. show lldp entry Hannah
E and F.
The show lldp neighbors command lists one line of output per neighbor. However, it does list the platform information of the neighbor, which typically includes the hardware model number. The show lldp entry Hannah command lists a group of messages about the neighboring router, including more detail about the hardware model and the IOS version.
