# X* q+ H, `( q4 h* r( cB It coordinates user authentication between a network device and a TACACS+ or RADIUS server.
C It sends information about M1B variables in response to requests from the NMS.
' G/ T7 A* K: b$ j1 b) VD It requests information from remote network nodes about catastrophic system events.
( R( Q; _! X: ^* ?/ ^# Q2  What are two reasons for an engineer to configure a floating static route? (Choose two.)
0 I( N' r* L5 m2 K5 DA to route traffic differently based on the source IP of the packet
1 Q0 ^8 k5 J- p$ x3 ?% s! h# w, [B to enable fallback static routing when the dynamic routing protocol fails
C to automatically route traffic on a secondary path when the primary path goes down
0 b' L  D* ?. _& q  l6 g; R' @D to control the return path of traffic that is sent from the router
E to support load balancing via static routing
( V6 D+ F* w4 y! w3 The service password-encryption command is entered on a router. What is the effect of this
( |8 Z* g: S4 ~6 xconfiguration?
A restricts unauthorized users from viewing clear-text passwords in the running configuration

5 What is a difference between RADIUS and TACACS+?
: e1 E$ L- ]3 J: O: I7 {A. TACACS+ encrypts only password information and RADIUS encrypts the entire payload

7 \1 u( D* R, T- w0 |6 AC. RADIUS is most appropriate for dial authentication, but TACACS+ can be used for multiple
types of
" K8 N3 y7 K8 C5 E7 lauthentication
/ F8 A% R1 `! @% J& TD. TACACS+ separates authentication and authorization, and RADIUS merges them

6How does Cisco DNA Center gather data from the network?
; n7 J1 u3 b, s6 EA Devices establish an IPsec tunnel to exchange data with the controller.
B Devices use the call-home protocol to periodically send data to the controller.
C Network devices use different services like SNMP, syslog, and streaming telemetry to send
data to the controller.
