Question 1


The command “ntp master [stratum]” is used to configure the device as an authoritative NTP server. You can specify a different stratum level from which NTP clients get their time synchronized. The range is from 1 to 15.

The stratum levels define the distance from the reference clock. A reference clock is a stratum 0 device that is assumed to be accurate and has little or no delay associated with it. Stratum 0 servers cannot be used on the network but they are directly connected to computers which then operate as stratum-1 servers. A stratum 1 time server acts as a primary network time standard.

A stratum 2 server is connected to the stratum 1 server; then a stratum 3 server is connected to the stratum 2 server and so on. A stratum 2 server gets its time via NTP packet requests from a stratum 1 server. A stratum 3 server gets its time via NTP packet requests from a stratum-2 server… A stratum server may also peer with other stratum servers at the same level to provide more stable and robust time for all devices in the peer group (for example a stratum 2 server can peer with other stratum 2 servers).

Question 2


The “ntp broadcast client” command is used under interface mode to allow the device to receive Network Time Protocol (NTP) broadcast packets on that interface

    All, I failed today with a 640. The ‘300-101: Implementing Cisco IP Routing’ exam is completely different then what is on this site. Not even close. There are maybe 10 questions that are the same… What happened???

    I had the same experience on the 4th.
    Seems like there is a new pool of questions.
    Lots of NTP and Netflow questions.

    Were the simulation the same as here?

    Although I have failed short of 5 marlks I have to say all the simulations are still based on these same topologies .There are more questions on infrastructure services and VPN technology that requires deeper understanding of the concepts to differentiate among the choices.

    Hey guys, I just wrote now in USA. I Passed 300-101 with 92%. This dumps http://www.testmayor.com/300-101-test.html is valid but a few answers are wrong. Although I don’t expect to pass with a full score, right? If your aim is just to pass the exam, only by memorizing the dumps is enough. But if you want to master skills, you really need to practice more.
