Q211. Which two statements are true about OTV? (Choose two.) 

A. It relies on flooding to propagate MAC address reachability information. 

B. It uses a full mesh of point-to-multipoint tunnels to prevent head-end replication of multicast traffic. 

C. It can work over any transport that can forward IP packets. 

D. It supports automatic detection of multihoming. 

Answer: C,D 

Explanation: 

The overlay nature of OTV allows it to work over any transport as long as this transport can forward IP packets. Any optimizations performed for IP in the transport will benefit the OTV encapsulated traffic. As part of the OTV control protocol, automatic detection of multihoming is included. This feature enables the multihoming of sites without requiring additional configuration or protocols

Q212. 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.

Q213. Which three options are results of the command no mpls ip propagate-ttl? (Choose three.) 

A. It prevents the TTL from being copied from the IP header to the MPLS header. 

B. It prevents the MPLS hops from being visible to a CE router when you perform a traceroute. 

C. A fixed TTL value of 255 is used for the first label of the IP packet. 

D. It prevents the TTL from being copied from the MPLS header back into the IP header. 

E. MPLS hops remain visible on a CE router when you perform a traceroute. 

F. A fixed TTL value of 1 is used for the first label of the IP packet. 

Answer: A,B,C 


Q214. Refer to the exhibit. 

Which prefixes will appear in the EIGRP topology table? 

A. 10.0.0.0/8, 172.16.1.0/24, 192.168.0.0/16 

B. 10.1.1.0/24, 10.1.2.0/24, 172.16.1.0/26, 192.168.1.0/26, 192.168.2.0/26 

C. 10.1.1.0/24, 10.1.2.0/24, 172.16.1.0/26, 172.16.2.0/26, 192.168.1.0/26, 192.168.2.0/26 

D. 10.1.1.1/24, 10.1.2.1/24, 172.16.1.1/26, 172, 192.168.1.1/26, 192.168.2.1/26 

Answer:


Q215. What is the function of the command ip pim autorp listener? 

A. It allows a border PIM sparse mode router to accept autorp information from another autonomous system. 

B. It allows the mapping agents to accept autorp information from the PIM rendezvous point. 

C. It allows the routers to flood the autorp information in a sparse-mode-only network. 

D. It allows a BSR to accept autorp information and translate it into BSR messages. 

Answer:

Explanation: 

To cause IP multicast traffic for the two Auto-RP groups 224.0.1.39 and 224.0.1.40 to be Protocol Independent Multicast (PIM) dense mode flooded across interfaces operating in PIM sparse mode, use the ip pim autorp listener command in global configuration mode. To disable this feature, use the no form of this command.

Q216. How does MSTP provide backward compatibility with RSTP? 

A. It uses the hop count variable as a TTL counter. 

B. It transmits all spanning-tree information in one BPDU. 

C. It supports up to 128 MSTI messages. 

D. It encodes the MSTP-specific region information before the legacy RSTP BPDU. 

Answer:


Q217. Which statement describes what it means if a router has an OSPF priority set to 0? 

A. A router with the OSPF priority set to 0 is one that can participate in the election of a DR. It has the highest priority. 

B. A router with the OSPF priority set to 0 is one that cannot participate in the election of a DR, but it can become a BDR 

C. A router with the OSPF priority set to 0 is one that cannot participate in the election of a DR. It can become neither a DR nor a BDR. 

D. A router with the OSPF priority set to 0 is one that cannot participate in the election of a BDR, but it can become a DR 

Answer:


Q218. Refer to the exhibit. 

What will be the extended community value of this route? 

A. RT:200:3000 RT:200:9999 

B. RT:200:9999 RT:200:3000 

C. RT:200:3000 

D. RT:200:9999 

Answer:

Explanation: 

Here the route map is being used to manually set the extended community RT to 200:9999 


Q219. What is the function of an implicit-null label? 

A. It notifies the upstream LSR to remove the top label in the label stack and forward the packet. 

B. It notifies the upstream LSR to add a VPN label to the label stack. 

C. It is used to statically assign a label to an IGP route. 

D. It is used to identify the router ID. 

Answer:


Q220. Refer to the exhibit. 

R1 is configured as shown. R1 is able to establish a neighbor adjacency only with R2. Which addition must you make to the R1 configuration to allow it to establish an adjacency with R3? 

A. interface gigabitethernet 0/1 

ip address 10.1.0.1 255.255.255.0 

ip ospf network point-to-point 

B. interface gigabitethernet 0/1 

ip address 10.1.0.1 255.255.255.0 

ip ospf 1 area 0 

C. router ospf 1 

network 10.1.0.0 0.0.0.255 area 1 

D. router ospf 1 

area 0 stub 

Answer:

Explanation: 

To enable interfaces and networks with OSPF, the networks need to be specified in the network statement. In the configuration shown, only 10.0.0.0/24 has been enabled, we are missing the network connecting to R3 (10.1.0.0/24).
