A CoPP policy is applied for receiving SSH traffic from the WAN interface on a Cisco ISR4321 router.However, the SSH response from the router is abnormal and stuck during the high link utilization. Theproblem is identified as SSH traffic does not match in the ACL. Which action resolves the issue?

• Rate-limit SSH traffic to ensure dedicated bandwidth.
• Apply CoPP on the control plane interface.
• Increase the IP precedence value of SSH traffic to 6.
• Apply CoPP on the WAN interface inbound direction.

An engineer is creating a policy that overrides normal routing behavior.if the route to a destination of10.100.100.0/24 is withdrawn from the routingTable, the policy must direct traffic to a next hop of 10.1.1. if the route is present in the routing table, thennormal forwarding must occur. Whichconfiguration meets the requirements?

• access-list 100 permit ip any ! route-map POLICY permit 10 match ip address 100 set ip next-hop recursive 10.1.1.1
• access-list 100 permit ip any 10.100.100.0.0.0.255 ! Route-map POLICY permit 10 match ip address 100 set ip default next-hop 10.1.1.1
• access-list 100 permit ip any 10.100.100.0.0.0.255 ! route-map POLICY permit 10 match ip address 100 set ip next-hop 10.1.1.1 ! route map POLICY permit 20
• access-list 100 permit ip any 10.100.100.0.0.0.255 ! route map POLICY permit 10 match ip address 100 Set ip next-hop recursive 10.1.1.1 ! route-map POLICY permit 20

Which Layer 3 VPN attribute installs customer routes in the VRF?

• extended-community
• MPLS label
• RD
• RT

Which two protocols can cause TCP starvation? (Choose two)

• TFTP
• SNMP
• SMTP
• HTTPS
• FTP

Which two components are required for MPLS Layer 3 VPN configuration? (Choose two)

• Use pseudowire for Layer 2 routes
• Use MP-BGP for customer routes
• Use OSPF between PE and CE
• Use a unique RD per customer VRF
• Use LDP for customer routes

What are the two prerequisites to enable BFD on Cisco routers? (Choose two)

• A supported IP routing protocol must be configured on the participating routers.
• OSPF Demand Circuit must run BFD on all participating routers.
• ICMP must be allowed on all participating routers.
• UDP port 1985 must be allowed on all participating routers.
• Cisco Express Forwarding and IP Routing must be enabled on all participating routers.

i.Which two labet distribution methods are used by routers in MPLS? (Choose two )

• targeted hello message
• LDP discovery hello message
• LDP session protection message
• downstream unsolicited
• downstream on demand

How is a preshared key 'Test'' for all the remote VPN rooters configured In a DMVPN using GRE over IPsec set up?

• authentication pre-share Test address 0.0.0.0.0.0.0
• set pre-share Test address 0.0.0.0.0.0.0
• crypto Ipsec key Test address 0.0.0.0.0.0.0
• crypto isakmp key Test address 0.0.0.0.0.0.0

A customer is running an mGRE DMVPN tunnel over WAN infrastructure between hub and spoke sites. The existing configuration allows NHRP to add spoke routers automatically to the multicast NHRP mappings. The customer is migrated the network from IPv4 to the IPv6 addressing scheme for those spokes' routers that support IPv6 and can run DMVPN tunnel over the IPv6 network. Which configuration must be applied to support IPv4 and IPv6 DMVPN tunnel on spoke routers?

• Tunnel mode ipv6ip 6to4
• Tunnel mode ipv6ip isatap
• Tunnel mode ipv6ip auto-tunnel
• Tunnel mode ipv6ip 6rd

How is the LDP router ID used in an MPLS network?

• The MPLS LOP router ID must match the IGP router ID.
• If not configured, the operational physical interface is chosen as the router ID oven d a loopback is configured.
• The loopback with the highest IP address is selected as the router ID
• The force keyword changes the router ID to the speeded address without causing any impact.
