Q1. A company plans to establish a new network using Cisco Catalyst switches for its multicast applications. What is the disadvantage when two multicast applications are using the multicast IP addresses 234.17.4.5 and 234.145.4.5 inside the same network? 

A. Multicast packets from both applications are flooded to all Layer 2 ports in a segment where a multicast receiver is located. 

B. Multicast packets from both applications are flooded to ports where one multicast receiver from one application is located. 

C. Only one multicast stream is received at the port where the receivers from both applications are located. 

D. Both multicast senders will always receive the multicast packets from the other multicast application. 

E. The routers doing PIM-SM cannot distinguish between the two multicast applications.

Q2. Refer to the exhibit. 

An enterprise is migrating its single-area OSPF network from a Frame Relay WAN service to an MPLS L3VPN service. Frame Relay will remain in only a few sites that require increased resiliency via two different WAN connections. 

Which feature could be used in the ?MPLS VPN service provider network to support the design requirement by ensuring that during normal operation, intersite traffic will only use the MPLS VPN service and not the old Frame Relay service? 

A. virtual links 

B. sham links 

C. multiple stub areas 

D. super backbone

Q3. A company wants to connect two data center sites using a hub-and-spoke design with 2000 remote sites. One design consideration is the requirement to transfer MPLS packets over the public Internet. In addition, one router at each site should be used, and the MPLS packets must be encapsulated inside IP packets because the public Internet cannot transfer native MPLS packets. Which feature can be used to simplify the network design? 

A. GET VPN can be used to encrypt the MPLS packets with IPsec. 

B. DMVPN can be used to build up GRE tunnels dynamically with MPLS encapsulation inside. 

C. L2TPv3 can be used to encapsulate the MPLS packets. 

D. Site-to-site IPsec without GRE can be used to encapsulate the MPLS packets. 

E. PPPoE can be used to encapsulate the MPLS packets.

Q4. You have designed a network to support two offices connected by a T1. Your router serial interfaces will be configured with encapsulation PPP. What will happen to your EIGRP neighbors if there is an LCP failure once your network is implemented? 

A. Your neighbors will drop after the EIGRP timers expire. 

B. Your neighbors will stay up because the link has not gone down. 

C. Your neighbors will drop immediately. 

D. Your neighbors will drop and EIGRP will begin the query process.

Q5. When creating a design plan for IPv6 integration, you decide to use stateless encapsulation of IPv6 packets into IPv4 tunnels between subscriber CPEs and a border relay. Which deployment technique allows for this functionality? 

A. 6rd 

B. Dual-Stack Lite 

C. 4rd 

D. DSTM

Q6. What is a key design aspect to be considered when designing an IP network that will be carrying real-time VoIP traffic? 

A. Minimizing total bidirectional end-to-end delay to 0-150 ms 

B. Minimizing total unidirectional end-to-end delay to 150-500 ms 

C. Minimizing total bidirectional end-to-end delay to 0-50 ms 

D. Minimizing total unidirectional end-to-end delay to 0-150 ms

Q7. When developing an MVPN design, which performance and scalability consideration must be taken into account? 

A. CE end-to-end PIM adjacency establishment 

B. multicast data sent to all PE routers on the default MDT 

C. RP placement in the multicast VRF 

D. RP placement in the customer network

Q8. A service provider creates a network design that runs MPLS in its WAN backbone using OSPF as the IGP routing protocol. What would be two effects of additionally implementing MPLS-TE? (Choose two.) 

A. MPLS-TE is required to reroute traffic within less than 1 second in case of a link failure inside the backbone. 

B. MPLS-TE is required to route different MPLS QoS service classes through different paths. 

C. MPLS-TE and OSPF cannot be used together inside one MPLS network. 

D. MPLS-TE cannot use OSPF for the traffic path calculation. 

E. MPLS-TE is required to create backup paths independently from the IGP.

Q9. You have been hired by Acme Corporation to evaluate their existing network and determine if the current network design is secure enough to prevent man-in-the-middle attacks. When evaluating the network, which switch security option should you investigate to ensure that authorized ARP responses take place according to known IP-to-MAC address mapping? 

A. ARP rate limiting 

B. DHCP snooping 

C. Dynamic ARP Inspections 

D. IP Source Guard

Q10. You are using iSCSI to transfer files between a 10 Gigabit Ethernet storage system and a 1 Gigabit Ethernet server. The performance is only approximately 700 Mb/s and output drops are occurring on the server switch port. Which action will improve performance in a cost-effective manner? 

A. Use a WRED random drop policy. 

B. Increase the queue to at least 1 GB. 

C. Enable the TCP Nagle algorithm on the receiver. 

D. Change the protocol to CIFS.
