Q1. You are the lead IP/MPLS network designer of a service provider called XYZ. You are leading a design discussion regarding IPv6 implementation in the XYZ MPLS network, using MPLS 6PE/6VPE techniques. Currently, XYZ provides IPv4 multicast services over an MPLS network by using MVPN, and would like to provide parallel IPv6 multicast services. Which three multicast solutions should be enabled? (Choose three.) 

A. native IPv6, only for multicast services 

B. MPLS 6PE/6VPE, because it provides IPv6 multicast support by default 

C. an overlay model using Layer 2 MPLS tunnels 

D. PIM-DM to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE 

E. MVPN for IPv6 multicast service

Q2. Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario? 

A. ISATAP 

B. 6to4 

C. DMVPN 

D. 6vPE 

E. 6PE

Q3. 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

Q4. You work as a network designer for a company that is replacing their Frame Relay WAN with an MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in their distribution routers, and they would like to advertise their access routers through the MPLS network. Their service provider, however, only supports 1000 prefixes per VRF. Which two design solutions can be applied to ensure that your access routers will be able to reach all devices in your network? (Choose two.) 

A. Use prefix lists on your distribution routers to control which routes are sent to the MPLS network. 

B. On your distribution routers, configure null routes and aggregate routes for the prefixes in your network. 

C. Configure your distribution routers to send a default route to the MPLS network. 

D. Summarize the routes on the MPLS WAN interfaces of your distribution routers.

Q5. Which two factors can significantly affect the OSPF network convergence time? (Choose two.) 

A. the tuning of OSPF LSA timers 

B. the number of OSPF routes 

C. the diameter of the OSPF network 

D. different processor capabilities of devices

Q6. An IBGP mesh design is being scoped, and in the discussions, one of the design engineers proposes the use of route reflectors. Which limitation is valid when using route reflectors in this design? 

A. The configuration complexity on the routers will be increased. 

B. Route reflectors will limit the total number of routes in the topology. 

C. Multipath information is difficult to propagate in a route reflector topology. 

D. Route reflectors will cause an opportunity to create routing loops.

Q7. Refer to the exhibit. 

Which two options are two characteristics of the single-tier headend architecture for DMVPN designs? (Choose two.) 

A. The mGRE and crypto functions are on the same router. 

B. Each DMVPN cloud has two different headend routers for high availability purposes. 

C. It is used in dual-cloud topologies for spoke-to-spoke connectivity. 

D. It only supports hub-and-spoke connectivity. 

E. Spokes cannot be used as RP in multicast deployments.

Q8. In an MPLS-VPN environment, what is the effect of configuring an identical set of route targets for a particular VRF, but then configuring nonidentical route distinguisher across multiple PE devices? 

A. The routes will be correctly handled by the control plane, but there will be instances where routes take up twice as much memory. 

B. The routes will propagate to the remote PE, but the PE will never install them in its forwarding table. 

C. The routes will be rejected by the remote PE because they have a different RD than its routes. 

D. The routes will not even be sent to any remote PE with a different RD.

Q9. Refer to the exhibit. 

Your company designed a network to allow server VLANs in a data center to span all access switches. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. In which three ways should the design of the STP domain be optimized for server and application performance? (Choose three.) 

A. Use loop guard on access ports. 

B. Use PortFast on access ports. 

C. Use root guard on access ports. 

D. Align Layer 2 and Layer 3 forwarding paths. 

E. Use BPDU Skew Detection on access ports. 

F. Explicitly determine root and backup root bridges.

Q10. You have been asked to design a wireless network solution that will implement context-aware services on an existing network that was initially deployed for data traffic only. Which two design principles would you follow to increase the location accuracy with the least possible impact on the current setup? (Choose two.) 

A. Use directional antennas to provide better cell separation. 

B. Add access points along the perimeter of the coverage area. 

C. Install additional APs in monitor mode where the cochannel interference would otherwise be affected. 

D. Increase the AP density to create an average interaccess point distance of less than 40 ft. 

E. Fine tune the access points radio configuration to have a higher average transmission power to achieve better coverage.
