Q1. Packets from a router with policy-based routing configured are failing to reach the next hop. 

Which two additions can you make to the router configuration to enable the packets to flow correctly? (Choose two.) 

A. Enable ip proxy-arp on the exiting interface. 

B. Specify the next hop as an address. 

C. Specify the next hop as an interface. 

D. Add a match-any permit statement to the route map. 

Answer: A,B 

Explanation: 

Here is an example: 

Router(config)#route-map Engineers permit 20 

Router(config-route-map)#match ip address 2 

Router(config-route-map)#set interface Ethernet1 

Here, instead of specifying a next-hop, it specifies that any packets matching this rule will be forwarded directly out the interface Ethernet1. This means that either the destination device must be on this segment, or there must be a router configured with Proxy ARP that can forward the packet to the ultimate destination. 


Q2. Which three statements about EIGRP wide metrics are true? (Choose three.) 

A. The maximum metric is 65536. 

B. The default delay is 1,000,000 picoseconds. 

C. They allow up to 100 hops. 

D. They allow up to 256 hops. 

E. The default delay is 1,000,000 milliseconds. 

F. The maximum metric is 51200. 

Answer: A,B,C 


Q3. A TCP/IP host is able to transmit small amounts of data (typically less than 1500 bytes), but attempts to transmit larger amounts of data hang and then time out. What is the cause of this problem? 

A. A link is flapping between two intermediate devices. 

B. The processor of an intermediate router is averaging 90 percent utilization. 

C. A port on the switch that is connected to the TCP/IP host is duplicating traffic and sending it to a port that has a sniffer attached. 

D. There is a PMTUD failure in the network path. 

Answer:

Explanation: 

Sometimes, over some IP paths, a TCP/IP node can send small amounts of data (typically less than 1500 bytes) with no difficulty, but transmission attempts with larger amounts of data hang, then time out. Often this is observed as a unidirectional problem in that large data transfers succeed in one direction but fail in the other direction. This problem is likely caused by the TCP MSS value, PMTUD failure, different LAN media types, or defective links.

Q4. DRAG DROP 

Drag and drop the IPv6 multicast feature or protocol on the left to the correct address space on the right. 

Answer: 


Q5. Which two protocols does the Management Plane Protection feature support? (Choose two.) 

A. ARP 

B. HTTPS 

C. TFTP 

D. OSPF 

Answer: B,C 


Q6. Which three features are common to OSPF and IS-IS? (Choose three.) 

A. They both maintain a link-state database from which a Dijkstra-based SPF algorithm computes a shortest path tree. 

B. They both use DR and BDR in the broadcast network. 

C. They both use hello packets to form and maintain adjacencies. 

D. They both use NSSA and stub type areas to scale the network design. 

E. They both have areas to form a two-level hierarchical topology. 

Answer: A,C,E 


Q7. Which three fields are part of a TCN BPDU? (Choose three.) 

A. protocol ID 

B. version 

C. type 

D. max-age 

E. flags 

F. message age 

Answer: A,B,C 


Q8. Which command do you use to connect a dense-mode domain to a sparse-mode multicast domain? 

A. none, because there is no such command 

B. ip pim spt-threshold infinity 

C. ip pim register dense-mode 

D. ip pim dense-mode proxy-register 

Answer:

Explanation: 

For IP PIM multicast, Cisco recommends Sparse-Mode over Dense-Mode. In the midst of our network migration, we have a new network operating in Sparse-Mode with Anycast rendezvous point (RP) but our existing network is still operating in Dense-Mode. To bridge two different modes across both PIM domains, we should use the ip pim dense-mode proxy-register command on the interface leading toward the bordering dense mode region. This configuration will enable the border router to register traffic from the dense mode region (which has no concept of registration) with the RP in the sparse mode domain.
