• Question 1131:

  What NTP Stratum level is a server that is connected directly to an authoritative time source?

  A. Stratum 0
  B. Stratum 1
  C. Stratum 14
  D. Stratum 15
  B. Stratum 1

  ---

  Explanation

  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). NTP uses the concept of a stratum to describe how many NTP hops away a machine is from an authoritative time source. A stratum 1 time server typically has an authoritative time source (such as a radio or atomic clock, or a Global Positioning System (GPS) time source) directly attached, a stratum 2 time server receives its time via NTP from a stratum 1 time server, and so on.

  Explanation

  When OSPF is running on a given loopback interface, it sees the network type of "LOOPBACK" and it knows that it can not establish an adjacency through that loopback interface with another router so it advertises that loopback as a host route or the only IP address on that logical interface. As Martin explained so nicely you can tell OSPF that it is not a loopback and it is a point-to-point network type, and OSPF says "OK I am going to advertise the interface with its correct mask". In MPLS environment where OSPF is the IGP in the core, and you have configured the loopback interface of the PE router with a /24 mask, you can have some problems, because there is a discrepancy, the loopback's mask is 24 but OSPF is advertising a mask of /32. There are few solutions to fix this problem, one solution is to reconfigure the mask to be /32, another solution is to configure the loopback interface with "ip ospf network point-to-point".
