# Z" N" U; B1 B- [1 Which function does an SNMP agent perform?
1 s. I/ X5 U" p0 H0 q; B9 N6 CA It manages routing between Layer 3 devices in a network,
$ f3 D  o; S7 c6 H1 MB 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.
D It requests information from remote network nodes about catastrophic system events.
2  What are two reasons for an engineer to configure a floating static route? (Choose two.)
0 H0 h) e+ r6 s. tA to route traffic differently based on the source IP of the packet
B to enable fallback static routing when the dynamic routing protocol fails
. `) n2 v* X! @" ZC to automatically route traffic on a secondary path when the primary path goes down
5 c$ c2 _% S# Y/ Q5 M* |! e, |' yD to control the return path of traffic that is sent from the router
E to support load balancing via static routing
3 The service password-encryption command is entered on a router. What is the effect of this
; i/ i8 J% I6 {* rconfiguration?
A restricts unauthorized users from viewing clear-text passwords in the running configuration
B encrypts the password exchange when a VPN tunnel is established
( A% c) ^7 w# K, w% ~; WC prevents network administrators from configuring clear-text passwords
; a6 \, J* k5 ]# N8 n5 N8 m- dD protects the VLAN database from unauthorized PC connections on the switch
' G2 j4 [% [" T: A' z+ P4
/ L) h& Y9 _* G& MRefer to the exhibit.The network administrator wants VLAN 67 traffic to be untagged between
Switch 1 and Switch 2,while all other VLANs are to remain tagged,which command accomplishes
this task ?
" q/ _5 c/ `. H. y6 }A switchport access vlan 67
B switchport trunk allowed vlan 67
: _: v: @& I9 R3 y& BC switchport private-vlan association host 67
D switchport trunk native vlan 67
5 What is a difference between RADIUS and TACACS+?
/ `0 ]  L4 j6 Q! cA. TACACS+ encrypts only password information and RADIUS encrypts the entire payload
3 j# E$ E; f+ z# R$ P  Q4 J! F8 yB. RADIUS logs all commands that are entered by the administrator, but TACACS+ logs only start,
stop, and interim commands
C. RADIUS is most appropriate for dial authentication, but TACACS+ can be used for multiple
types of
+ x5 ^2 p9 x* e1 Z3 y" \authentication
' `- u0 ?% l) g; j2 yD. TACACS+ separates authentication and authorization, and RADIUS merges them
# a( M) D9 `* ?0 R$ C; t1 N! uAnswer: D
. F8 P+ c+ z3 c4 v' z6How does Cisco DNA Center gather data from the network?
A Devices establish an IPsec tunnel to exchange data with the controller.
2 Z+ v% \$ h. `, q# O$ HB Devices use the call-home protocol to periodically send data to the controller.
. M' s3 ]9 R. f/ r0 ]- qC Network devices use different services like SNMP, syslog, and streaming telemetry to send
data to the controller.
1 v) T% \- K; G, ?, ~" LD The Cisco CLI Analyzer tool gathers data from each licensed network device .and streams it to
the controller.
