A.NTP updates are sent in the timezone they are collected in，and the syslog server will adjust based on the input time.
B.NTP authentication verifies the source，not the recipient.
C.NTP authentication requires that the recipient has multiple strata clocks to ensure accuracy.

Based on the exhibit presented. What will be the objective of this route map when applied to traffic passing through a router？（）
Which three options are valid ways to filter routes from a BGP peer？（）
Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correctBGP session endpoint addresses and the correct BGP session hop-count limit EBGP multihop. What is agood first test to see if BGP will work across the firewall？（）
Spanning Tree Protocol IEEE 802.1 s defines the ability to deploy which of these？（）
Which two EIGRP options will limit a query domain？（）
Which message type is constructed and sent from an MSDP router to its MSDP peers when it receives a PIM register message knowing that the MSDP router is also configured as an RP for the PIM domain？（）
What is the correct command to set the router ID for an OSPFv3 process？（）
An expanding company is deploying leased lines between its main site and two remote sites. Thebandwidth of the leased lines is 128kb/s each，terminated on different serial interfaces on the main router.These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs，and has therefore reserved sufficient bandwidth in a low latency queue oneach interface for the VOIP traffic. Users now complain about bad voice quality although no drops areobserved in the low latency queue. What action will likely fix this problem？（）
Which multicast address is reserved for cisco-rp-discovery？（）
Which three message types are valid PIMv2 message types？（）
