Answer: A
Q2. 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.
Answer: B
Q3. A switched network is being designed to support a manufacturing factory. Due to cost constraints, fiber-based connectivity is not an option. Which design allows for a stable network when there is a risk of interference from the manufacturing hardware in use on the factory floor?
A. Design the network to include UDLD to detect unidirectional links and take them out of service.
B. Design the network to include EtherChannel bundles to prevent a single-link failure from taking down a switch interconnection point.
C. Design the network to include loop guard to prevent a loop in the switched network when a link has too much interference.
D. Design the network to include BackboneFast on all devices to accelerate failure convergence times.
Answer: A
Q4. A company plans to use BFD between its routers to detect a connectivity problem inside the switched network. An IPS is transparently installed between the switches. Which packets should the IPS forward for BFD to work under all circumstances?
A. IP packets with broadcast IP source addresses
B. IP packets with identical source and destination IP addresses
C. fragmented packets with the do-not-fragment bit set
D. IP packets with the multicast IP source address
E. IP packets with the multicast IP destination address
F. IP packets with the destination IP address 0.0.0.0
Answer: B
Q5. You are designing a multisite VPN solution for a customer and you are concerned with the additional overhead of point-to-point tunnels and the associated overlay routing with DMVPN. How does a GDOI-based VPN eliminate the additional tunnel and routing overhead found in DMVPN?
A. The GDOI-based VPN requires overlaying a secondary routing infrastructure through the tunnels.
B. In a GDOI-based VPN, all group members share a common security association.
C. The GDOI-based VPN requires the provisioning of a complex connectivity mesh.
D. The GDOI-based VPN leverages the routing protocol to find its peer for tunnel setup.
Answer: B
Q6. You have been tasked to create a Layer 2 network design that uses vPC to provide resiliency and avoid loops. vPC removes Layer 2 loops while providing redundancy through which mechanism?
A. dual-active detection
B. address synchronization
C. strict forwarding rules
D. Bridge Assurance
Answer: C
Q7. A Mobile Service Provider would like to design and deploy an Ethernet service which has similar physical link failover/failback characteristics on the active/backup links as the APS/MSP SONET properties. Which Layer 2 services should be considered to address this design feature?
A. Port-Channel
B. MLPPP
C. Flex Link
D. Ethernet Pseudowires
Answer: C
Q8. Refer to the exhibit.
You are designing a spanning-tree network for a small campus. Which two of these options would result in a trouble-free spanning-tree network design? (Choose two.)
A. Convert all ports to trunk ports, prune off the VLANs that you do not require, and minimize the number of blocking ports.
B. Introduce Layer 3 VLANs (SVIs) and prune off the VLANs that you do not require.
C. Convert all the ports to trunk and enable BackboneFast.
D. Convert all the ports to trunk and enable UplinkFast between all the links.
Answer: AB
Q9. You are designing an 802.11 wireless network to include a controller as a central configuration point and access points across several remote sites. Which two aspects will manage the flow of the traffic to meet these design considerations? (Choose two.)
A. WLAN local switching with VLAN mapping requires that VLAN ID that is mapped on the AP to match a dynamic interface that is configured on the wireless LAN controller.
B. Layer 3 roaming is not supported for locally switched WLANs.
C. The 802.1x authentication for a client associated to an AP on a locally switched WLAN is always handled at the wireless LAN controller side.
D. The access point can receive multicast traffic in the form of multicast packets from the WLC.
E. WLAN access lists can be applied only to centrally switched WLANs.
Answer: BE
Q10. AS100 and AS200 each have two peering points in different parts of their network. AS100 would like to use one of the links and keep the other link as backup. What should be changed for the design inside AS100 for prefixes received from AS200?
A. MED
B. weight
C. AS-PATH
D. local preference
Answer: D
