Q1. The direction of the flow of multicast traffic is based on which protocol? 



C. underlying IGP 



Q2. Which option is a primary requirement for the deployment of an IPv6-enabled network via the native method (dual-stack model) within the enterprise campus environment? 

A. hardware-based switching support for IPv6 forwarding on all campus switches 

B. restriction of IPv6-enabled devices to the core layer 

C. manual implementation of tunneling between IPv6-incompatible devices in an IPv4-over-IPv6 tunnel 

D. disabling of multicast in the distribution layer prior to implementation of IPv6 


Q3. Which algorithm does IS-IS use to determine the shortest path through a network? 

A. Bellman-Ford routing algorithm 

B. Johnson's.algorithm 

C. Dijkstra's algorithm 

D. Floyd-Warshall algorithm 


Q4. Which four Cisco proprietary Spanning Tree Protocol enhancements are supported with rapid per-VLAN Spanning-Tree plus? (Choose four.) 

A. PortFast 

B. UplinkFast 

C. loop guard 

D. root guard 

E. BPDU guard 

F. BackboneFast 

Answer: A,C,D,E 

Q5. When considering the design of the E-Commerce topology which of the following are true? 

A. One-armed SLB design with multiple security contexts removes the need for a separate firewall in the core layer 

B. Two-firewall-layer SLB design considers the aggregation and access layers to be trusted zones, requiring no security between the web, application, and database zones 

C. One-armed SLB design with two firewall layers ensures that non load-balanced traffic still traverses the ACE so that the health and performance of the servers is still being monitored 

D. In all cases there will be configuration requirements for direct access to any servers or for nonload-balanced sessions initiated by the servers 


Q6. A BGP network is having difficulty scaling with the full mesh peer requirement. What two iBGP alternates can scale BGP appropriately? (Choose two.) 

A. communities 

B. route reflectors 

C. confederations 

D. peer groups 

E. peer templates 

Answer: B,C 

Q7. Which three of these Metro service types map to E-Line (versus E-LAN) services that are defined by the Metro Ethernet Forum (MEF)? (Choose three.) 

A. Ethernet Private Line 

B. Ethernet Wire Service 

C. Ethernet Relay Service 

D. Ethernet Multipoint Service 

E. Ethernet Relay Multipoint Service 

Answer: A,B,C 

Q8. Which two protocol characteristics should be most considered when designing a single unified fabric for the Data Center? (Choose two.) 

A. FCIP or FCoE allow for easier integration by using the Fibre Channel Protocol (FCP) and Fibre Channel framing 

B. iSCSI uses a special EtherType and an additional header containing additional control information 

C. FCIP and iSCSI has higher overhead than FCoE owing to TCP/IP 

D. FCoE was initially developed to be used as a switch-to-switch protocol, while FCIP is primarily meant to be used as an access layer protocol to connect hosts and storage to a Fibre Channel SAN 

E. FCoE requires gateway functionality to integrate into an existing Fibre Channel network 

Answer: A,C 

Q9. EIGRP uses which algorithm to build a routing table? 

A. Dijkstra's algorithm 

B. Floyd-Warshall algorithm 

C. Diffusing Update Algorithm 

D. Johnson's algorithm 


Q10. CoS is applied for Layer 2 markings in an Ethernet environment. Which protocol must be configured on the Layer 2 switch port for CoS to work? 


B. IEEE 802.1W 

C. IEEE 802.1Q 

D. IEEE 802.1S
