Q161. Refer to the exhibit. 

Which statement is true? 

A. The Cisco PfR state is UP; however, the external interface Et0/1 of border router 10.1.1.1 has exceeded the maximum available bandwidth threshold. 

B. The Cisco PfR state is UP; however, an issue is preventing the border router from establishing a TCP session to the master controller. 

C. The Cisco PfR state is UP and is able to monitor traffic flows; however, MD5 authentication has not been successful between the master controller and the border routers. 

D. The Cisco PfR State is UP; however, the receive capacity was not configured for inbound traffic. 

E. The Cisco PfR state is UP, and the link utilization out-of-policy threshold is set to 90 percent for traffic exiting the external links. 

Answer:

Explanation: 

All three interfaces show as UP, and the capacity is set to 500 kbps, with the max threshold set to 450 kbps (90% of 500kbps). 


Q162. Refer to the exhibit. 

Which statement about the configuration is true? 

A. This configuration is incorrect because the dialer interface number must be the same as the dialer pool number. 

B. This configuration is missing an IP address on the dialer interface. 

C. This configuration is incorrect because the MTU must match the ppp-max-payload that is defined. 

D. This configuration represents a complete PPPoE client configuration on an Ethernet connection. 

Answer:


Q163. Refer to the exhibit. 

What happens to packets when traffic in the icmp-class class exceeds the policed amount? 

A. Packets are discarded and a message is logged. 

B. Packets are discarded and a trap is sent to any servers that are configured to receive traps. 

C. Packets are discarded silently. 

D. Packets are discarded and an inform is sent to any servers that are configured to receive informs. 

Answer:

Explanation: 

service-policy {input| output policy-map-name Example: 

Router(config-cp)# service-policy input control-plane-policy 

Attaches a QoS service policy to the control plane. Note the following points: 

. input --Applies the specified service policy to packets received on the control plane. 

. output --Applies the specified service policy to packets transmitted from the control plane and enables the router to silently discard packets. 

. policy-map-name --Name of a service policy map (created using the policy-mapcommand) to be attached. The name can be a maximum of 40 alphanumeric characters. 

In this case, the service policy is set to output, which drops the traffic silently per above.

Q164. DRAG DROP 

Drag and drop each BGP attribute on the left to the matching description on the right. 

Answer: 


Q165. Which three features does GETVPN support to improve deployment and scalability? (Choose three.) 

A. configuration of multiple key servers to work cooperatively 

B. allowing traffic to be discarded until a group member registers successfully 

C. local exceptions in the traffic classification ACL 

D. GDOI protocol configuration between group members and the key server 

E. redundant IPsec tunnels between group members and the key server 

F. redundant multicast replication streaming through the use of a bypass tunnel 

Answer: A,B,C 


Q166. Which standard feature can be exploited by an attacker to perform network reconnaissance? 

A. IP-directed broadcast 

B. maintenance operations protocol 

C. ICMP redirects 

D. source quench 

Answer:


Q167. Refer to the exhibit. 

Which two statements about the output are true? (Choose two.) 

A. 802.1D spanning tree is being used. 

B. Setting the priority of this switch to 0 for VLAN 1 would cause it to become the new root. 

C. The hello, max-age, and forward delay timers are not set to their default values. 

D. Spanning-tree PortFast is enabled on GigabitEthernet1/1. 

Answer: A,B 

Explanation: 

802.1D is the standard for Spanning tree, which is being used here. For priority, The priority order starts from 0 (yes, 0 is valid) and then increases in 4096. 0, 4096, 8192, 12288, …. Etc. 

The lower the number is, the higher is the priority. Here we see that the current root has a priority of 8192, so configuring this with a priority of 0 will make it the new root. 


Q168. Which three characteristics are shared by subinterfaces and associated EVNs? (Choose three.) 

A. IP address 

B. routing table 

C. forwarding table 

D. access control lists 

E. NetFlow configuration 

Answer: A,B,C 


Q169. Which two statements about the function of the stub feature in EIGRP are true? (Choose two.) 

A. It stops the stub router from sending queries to peers. 

B. It stops the hub router from sending queries to the stub router. 

C. It stops the stub router from propagating dynamically learned EIGRP prefixes to the hub routers. 

D. It stops the hub router from propagating dynamically learned EIGRP prefixes to the stub routers. 

Answer: B,C 

Explanation: 

When using the EIGRP Stub Routing feature, you need to configure the distribution and remote routers to use EIGRP, and to configure only the remote router as a stub. Only specified routes are propagated from the remote (stub) router. The router responds to queries for summaries, connected routes, redistributed static routes, external routes, and internal routes with the message "inaccessible." A router that is configured as a stub will send a special peer information packet to all neighboring routers to report its status as a stub router. Without the stub feature, even after the routes that are sent from the distribution router to the remote router have been filtered or summarized, a problem might occur. If a route is lost somewhere in the corporate network, EIGRP could send a query to the distribution router, which in turn will send a query to the remote router even if routes are being summarized. If there is a problem communicating over the WAN link between the distribution router and the remote router, an EIGRP stuck in active (SIA) condition could occur and cause instability elsewhere in the network. The EIGRP Stub Routing feature allows a network administrator to prevent queries from being sent to the remote router.

Q170. Which two mechanisms provide Cisco IOS XE Software with control plane and data plane separation? (Choose two.) 

A. Forwarding and Feature Manager 

B. Forwarding Engine Driver 

C. Forwarding Performance Management 

D. Forwarding Information Base 

Answer: A,B 

Explanation: 

Control Plane and Data Plane Separation 

IOS XE introduces an opportunity to enable teams to now build drivers for new Data Plane ASICs outside the IOS instance and have them program to a set of standard APIs which in turn enforces Control Plane and Data Plane processing separation. IOS XE accomplishes Control Plane / Data Plane separation through the introduction of the Forwarding and Feature Manager (FFM) and its standard interface to the Forwarding Engine Driver (FED). FFM provides a set of APIs to Control Plane processes. In turn, the FFM programs the Data Plane via the FED and maintains forwarding state for the system. The FED is the instantiation of the hardware driver for the Data Plane and is provided by the platform.
