   Why is accurate time synchronization important for network devices such as switches and routers?

   • AIt reduces the amount of bandwidth consumed by routing updates
   • BIt ensures that log entries and security events can be correlated across devices
   • CIt allows devices to automatically negotiate IP addresses without DHCP
   • DIt increases the forwarding speed of packets through the switch fabric

   A network administrator has two Dell switches, SW1 and SW2, in a small office. There is no external NTP server available. The administrator wants to ensure both switches have the same time for log correlation. The administrator configures SW1 as an NTP server (using its local clock) and SW2 as a client of SW1. What is a potential issue with this setup?

   • ASW2 will not be able to sync to SW1 because SW1 is not a stratum-1 server.
   • BSW1's clock will drift over time, and SW2 will inherit that drift.
   • CSW1 and SW2 will not be able to communicate because they are on the same network.
   • DSW2 will not sync because SW1 is not configured as a peer.

   A Dell switch is synced to an NTP server. The administrator wants to verify the time offset between the switch and the server. Which command provides this information?

   • Ashow ntp associations
   • Bshow clock
   • Cshow ntp status
   • Dshow ntp config

   Which statement best describes the relationship between stratum level and time accuracy in NTP?

   • ALower stratum numbers indicate greater accuracy because they are closer to the reference clock
   • BAccuracy is determined solely by the number of peer devices, not stratum
   • CHigher stratum numbers indicate greater accuracy because they have more sources
   • DStratum level has no effect on accuracy; only the hardware clock quality matters
