QUESTION


Bangkok is using ECMP to reach to the 192.168.5.0/24 network. The administrator must configure Bangkok in such a way that Telnet traffic from 192.168.3.0/24 and 192.168.4.0/24 networks uses the HongKong router as the preferred router.


Which set of configurations accomplishes this task?
A . access-list 101 permit tcp 192.168.3.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
route-map PBR1 permit 10
match ip address 101
set ip next-hop 172.18.1.2
interface Ethernet0/3
ip policy route-map PBR1


B . access-list 101 permit tcp 192.168.3.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
route-map PBR1 permit 10
match ip address 101
set ip next-hop 172.18.1.2
interface Ethernet0/1
ip policy route-map PBR1


C . access-list 101 permit tcp 192.168.3.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
!
route-map PBR1 permit 10
match ip address 101
set ip next-hop 172.18.1.2
!
interface Ethernet0/1
ip policy route-map PBR1


D . access-list 101 permit tcp 192.168.3.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23
access-list 101 permit tcp 192.168.4.0 0.0.0.255 192.168.5.0 0.0.0.255 eq 23

A. The P routers must be configured for MP-iBGP toward the PE routers
E.The P and PE routers must be configured with LDP or RSVP

Reference:

PE Router
Use MPLS with P routers
Distributes VPN routes using MP-iBGP session to othter PE routers

dicky_wong617:When configuring Control Plane Policing on a router to protect it from malicious traffic, an engineer observes
that the configured routing protocols start flapping on that device. Which action in the Control Plane Policy
prevents this problem in a production environment while achieving the security objective?
A . Set the conform-action and exceed-action to transmit initially to test the ACLs and transmit rate and apply
the Control Plane Policy in the output direction
B. Set the conform-action and exceed-action to transmit initially to test the ACLs and transmit rate and apply
the Control Plane Policy in the input direction
C. Set the conform-action to transmit and exceed-action to drop to test the ACLs and transmit rate and apply
the Control Plane Policy in the output direction
D. Set the conform-action to transmit and exceed-action to drop to test the ACLs and transmit rate and apply
the Control Plane Policy in the input direction

題庫正確答案系B定系D ,我認為系in the input direction ,系不明白drop to test同transmit initially to test ACL有甚麽分別,請給意見及解題,感謝感謝!!
