A. untrusted VLAN
B. user VLAN
C. management VLAN
D. authentication VLAN
Answer: A
Q2. A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A customer wants to connect one site with one box redundant to theResilient Ethernet Protocol ring at two different service provider locations. How can this be done without producing any Layer 2 loops within the network design?
A. Spanning tree at the service provider side only must be enabled.
B. Spanning tree at the customer side only must be enabled.
C. Flex Links at the service provider side only must be enabled.
D. Flex Links at the customer side only must be enabled.
E. EtherChannel at the service provider side and the customer side must be enabled.
F. Spanning tree at the service provider side and the customer side must be enabled.
G. Flex Links at the service provider side and the customer side must be enabled.
Answer: D
Q3. Your company is designing a service provider network management solution in which customers are billed for 95th percentile network utilization. The service provider requires that an IETF standard be utilized to collect the data. Which method should be used to collect the data?
A. IPFIX
B. NETFLOW
C. RMON
D. IPFLOW
E. NBAR
Answer: A
Q4. Refer to the exhibit.
Which single design aspect should be configured on the ABRs to reduce the impact of WAN upgrades for spoke routers on the core of the network?
A. route summarization
B. stub area
C. route filtering
D. not-so-stubby area
Answer: A
Q5. You are evaluating convergence characteristics of various interior gateway protocols for a new network design. Which technology allows link-state routing protocols to calculate paths to destination prefixes that are functionally similar to feasible successors in Enhanced Interior Gateway Routing Protocol?
A. Incremental Shortest Path First
B. Cisco Multiprotocol Label Switching Traffic Engineering Fast Reroute
C. Loop-Free Alternate Fast Reroute
D. partial route calculation
E. Fast-Flooding
Answer: C
Q6. 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
Answer: A
Q7. 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
Answer: B
Q8. In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers. How would you redesign the network to improve stability?
A. Add a layer of regional Layer 3 aggregation devices, but leave the ABR function on the data center aggregation routers.
B. Add a layer of regional Layer 2 aggregation devices, but leave the ABR function on the data center aggregation routers.
C. Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device.
D. Add a layer of regional Layer 2 aggregation devices and move the ABR function to the regional aggregation device.
Answer: C
Q9. You are hired to design a solution that will improve network availability for users on a campus network with routed access. If the budget limits you to three components, which three components would you recommend in your design proposal? (Choose three.)
A. redundant power supplies in the access routers
B. standby route processors for SSO in the core routers
C. standby route processors for SSO in the distribution routers
D. standby route processors for SSO in the access routers
E. replace copper links between devices with fiber links
Answer: ADE
Q10. You are designing a wireless LAN with the following components:
High-density indoor access point deployment
2.4-GHz and 5-GHz radios
802.11a, 802.11g, and 802.11n mode wireless LAN clients
Site survey results show negligible foreign WiFi and non-WiFi interference. What is the best method to decrease duty cycle (radio frequency utilization) and increase overall wireless LAN client performance for this design?
A. Disable all data rates below 12 Mb/s on all access points.
B. Decrease radio transmit power on all access points that report a high duty cycle.
C. Increase radio transmit power on all access points that report a high duty cycle.
D. Disable all data rates above 12 Mb/s on all access points.
E. Increase radio transmit power on all access points.
Answer: A
Q11. 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
Answer: B
Q12. Refer to the exhibit.
This Layer 2 ring has 10 VLANs with 1000 MAC addresses in each VLAN. Which protocol or mechanism provides the shortest traffic outage if the link marked with "X" fails?
A. PVRST
B. REP
C. MST
D. G.8031
E. BFD
Answer: B
Q13. You are a network designer and are responsible for ensuring that the network you design is secure. How do you plan to prevent infected devices on your network from sourcing random DDoS attacks using forged source addresses?
A. ACL-based forwarding
B. ACL filtering by destination
C. Unicast RPF loose mode
D. Unicast RPF strict mode
Answer: D
Q14. Refer to the exhibit.
The design is being proposed for use within the network. The CE devices are OSPF graceful restart-capable, and the core devices are OSPF graceful restart-aware.
