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.
D.Secure NTP can be configured to use SHA-1 hashing，since NTP is very insecure.
E.A stratum 0 clock should be configured at the core of every network，so it can connect to an accuratetime source.

B. The customer side is supposed to be running PAgP, which is a Cisco standard.
C. PAgP is not an IEEE standard. VRRP should be used.
D. The configuration on switch1 needs to be modified to use LACP.

Refer to the exhibit. Router E learned about the PIM RP （designated as 7.7.7.7） from four different sources. Routers A and D advertised the 7.0.0.0 network via EIGRP. Routers B and C advertised the 7.0.0.0 network via OSPF. Considering that all four Ethernet interfaces on router E could potentially lead back to the PIM-RP， when router E receives the first multicast packet down the shared tree， which incoming interface will be used to successfully pass the RPF check？（）
A. E0
B. E1
C. E2
D. E3
E. None of these interfaces will be used to successfully pass the RPF check.
F. All of these interfaces would successfully pass the RPF check.

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.

You are the network administrator of an enterprise with a main site and multiple remote sites. Your networkcarries both VOIP and data traffic. You agree with your service provider to classify VOIP and data trafficaccording to the different service RFCs. How can your data and VOIP traffic be marked？（）
Which multicast address is reserved for cisco-rp-discovery？（）
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 two statements about SA caching are true？（）
