Q41. Which two statements about Cisco Performance Routing are true? (Choose two.) 

A. It analyzes application performance to make routing decisions. 

B. When determining the best path, it prefers the shortest path. 

C. It can help the administrator determine the need for bandwidth upgrades. 

D. It operates entirely in the data plane. 

E. It can use EIGRP feasible successors to determine an alternate path. 

F. It analyzes system hardware performance to make routing decisions. 

Answer: A,E 

Q42. Which option describes the purpose of the leak-map keyword in the command eigrp stub connected leak-map EigrpLeak? 

A. It allows the specified static routes to be advertised. 

B. It allows exceptions to the route summarization that is configured. 

C. It allows specified EIGRP-learned routes to be advertised. 

D. It restricts specified connected routes from being advertised. 



ExamplE. eigrp stub leak-map Command 

In the following example, the eigrp stub command is issued with the leak-map name keyword-argument pair to configure the device to reference a leak map that identifies routes to be advertised that would have been suppressed otherwisE. 

Device(config)# router eigrp 1 

Device(config-router)# network 

Device(config-router)# eigrp stub leak-map map1

Q43. The no ip unreachables command is configured on interfaces to protect the control plane of a router. 

Which mechanism is impacted by using this command? 

A. ICMP redirects 

B. path MTU discovery 

C. source routing 

D. ICMP router discovery protocol 


Q44. Which two statements about port ACLs are true? (Choose two.) 

A. Port ACLs are supported on physical interfaces and are configured on a Layer 2 interface on a switch. 

B. Port ACLs support both outbound and inbound traffic filtering. 

C. When it is applied to trunk ports, the port ACL filters only native VLAN traffic. 

D. When it is applied to a port with voice VLAN, the port ACL filters both voice and data VLAN traffic. 

Answer: A,D 


PACLs filter incoming traffic on Layer 2 interfaces, using Layer 3 information, Layer 4 header information, or non-IP Layer 2 information The port ACL (PACL) feature provides the ability to perform access control on specific Layer 2 ports. A Layer 2 port is a physical LAN or trunk port that belongs to a VLAN. Port ACLs perform access control on all traffic entering the specified Layer 2 port, including voice and data VLANs that may be configured on the port. Port ACLs are applied only on the ingress traffic.

Q45. Refer to the exhibit. 

If a console port is configured as shown, which response is displayed when you connect to the console port? 

A. a blinking cursor 

B. the message "Authorized users only" 

C. the username prompt 

D. three username name prompts followed by a timeout message 

E. the message "Connection refused" 


Q46. Refer to the exhibit. 

Which BGP feature allows R1 to instruct R2 which prefixes it is allowed to advertise to R1? 

A. route refresh 

B. Prefix-Based Outbound Route Filtering 

C. distribute lists 

D. prefix lists 


Q47. Refer to the exhibit. 

Which two statements about how the configuration processes Telnet traffic are true? (Choose two.) 

A. Telnet traffic from to is dropped. 

B. All Telnet traffic is dropped. 

C. Telnet traffic from to is permitted. 

D. Telnet traffic from to is permitted. 

E. Telnet traffic is permitted to all IP addresses. 

Answer: A,C 


The ACL applied to the COPP policy matches only telnet traffic from to, all other telnet traffic is not matched and therefore not used in the COPP policy, which means this traffic will be handled normally (accepted). For telnet traffic from to, the COPP policy has defined this traffic as an exceed, and dropped. 

Q48. A floating static route appears in the routing table of an interface even when the interface is unusable. 

Which action can you take to correct the problem? 

A. Remove the permanent option from the static route. 

B. Correct the administrative distance. 

C. Configure the floating static route to point to another route in the routing table. 

D. Correct the DHCP-provided route on the DHCP server. 



Drag and drop the RIP configuration command on the left to the function it performs on the right. 


Q50. Which two statements are true about unicast RPF? (Choose two.) 

A. Unicast RPF requires CEF to be enabled. 

B. Unicast RPF strict mode works better with multihomed networks. 

C. Unicast RPF strict mode supports symmetric paths. 

D. Unicast RPF strict mode supports asymmetric paths. 

E. CEF is optional with Unicast RPF, but when CEF is enabled it provides better performance. 

Answer: A,C 


Unicast RPF requires Cisco express forwarding (CEF) to function properly on the router. 

Strict Versus Loose Checking Mode 

The Unicast RPF in Strict Mode feature filters ingress IPv4 traffic in strict checking mode and forwards packets only if the following conditions are satisfied. 

. An IPv4 packet must be received at an interface with the best return path (route) to the packet source (a process called symmetric routing). There must be a route in the Forwarding Information Base (FIB) that matches the route to the receiving interface. Adding a route in the FIB can be done via static route, network statement, or dynamic routing. 

. IPv4 source addresses at the receiving interface must match the routing entry for the interface.
