Q1. What device virtualization technology allows for a single point of management and a centralized routing instance?
A. ACE
B. VSS
C. VDC
D. VM
Answer: B
Q2. During the design of a new campus network, the customer requests the ability to route overlapping IP addresses. What technology can be leveraged to meet this request?
A. VRF
B. VLANs
C. VSS
D. VPC
Answer: A
Q3. A network engineer is using the traditional switched hierarchical design. The client has asked to increase uplink utilization from the access layer to the distribution. How can the engineer attain this new requirement without adding new physical connections?
A. enable spanning-tree portfast
B. enable VSS at the distribution layer
C. increase the MTU size on the uplink interfaces
D. ensure the root bridge priority is equal on both distribution switches
Answer: B
Q4. Which four services does the architecture for Media Services contain? (Choose four.)
A. access services
B. transport services
C. storage services
D. forwarding services
E. session control services
F. security services
G. filtering services
H. remote access services
Answer: A,B,C,E
Explanation:
An architecture framework for media services supports different models of video models. As shown in Figure 14-13, the network provides service to video media in the Media Services Framework. Those services are access services, transport services, bridging services, storage servers, and session control services, which arc provided to endpoints.
Access services provide identity of end devices, mobility, and location services.
Transport services provide QoS for reliable packet delivery.
Bridging services provide transcoding, conferencing, and recording services of media streams.
Storage services provide capture and storage of media streams and content management and distribution.
Session control services provide session signaling and control and gateway services.
Q5. An organization needs a WAN Transport technology that meets these criteria:
. has a low initial cost
. provides low-to-medium BW
. has medium-to-high latency and jitter
Which technology should the organization use?
A. DSL
B. X.25
C. ISDN
D. wireless
E. analog modem
Answer: A
Q6. Where in the network hierarchy should network access control be performed?
A. backbone
B. core
C. access
D. distribution
Answer: C
Q7. Which RFC defines the IPv6 standard?
A. RFC 1918
B. RFC 2338
C. RFC 2460
D. RFC 2740
Answer: C
Q8. What is the acceptable amount of one-way network delay for voice and video applications?
A. 300 bytes
B. 1 sec C. 150 ms
D. 500 ms
Answer: C
Explanation:
Delay Components in VoIP Networks The ITU's G.I 14 recommendation specifics that the one-way delay between endpoints should not exceed 150 ms to be acceptable, commercial voice quality. In private networks, somewhat longer delays might be acceptable for economic reasons. The ITU G.114 recommendation specifics that 151-ms to 400-ms one-way delay might be acceptable provided that organizations are aware that the transmission time will affect the quality of user applications. One-way delays of above 400 ms are unacceptable for general network planning purposes.
Q9. DRAG DROP
Answer:
Q10. What is the primary consideration when choosing a routed network design over a traditional campus network design?
A. Layer 3 service support at the network edge
B. the routing protocol choice: open (OSPF) or proprietary (EIGRP)
C. the routing abilities of the host devices
D. the need to control the broadcast domains within the campus core
Answer: A
Explanation: Layer 3 ability at network edge should be available to leverage the benefits of routed network design. Link: http://www.cisco.com/en/US/docs/solutions/Enterprise/Campus/campover.html
Q11. A network engineer is using the Cisco enterprise architecture model. In what module do network management servers reside?
A. Enterprise Campus
B. Enterprise Edge
C. Remote Modules
D. SP Edge WAN/internet
Answer: A
Q12. Which first-hop redundancy protocol dynamically distributes client traffic between multiple routers?
A. HSRP
B. VRRP
C. GLBP
D. IGRP
Answer: C
Q13. Which one of these statements describes why, from a design perspective, a managed VPN approach for enterprise teleworkers is most effective?
A. A managed VPN solution uses a cost-effective, on-demand VPN tunnel back to the enterprise.
B. This solution supports all teleworkers who do not require voice or video.
C. This architecture provides centralized management where the enterprise can apply security policies and push configurations.
D. It provides complete flexibility for remote access through a wireless hotspot or a guest network at a hotel, in addition to a home office.
Answer: C
Q14. A company has dark fiber between headquarters and its data center. It is presently configured as a 10GbE connection. Network utilization shows high utilization on the connection. What technology can be implemented to increase capacity without acquiring another circuit?
A. MPLS
B. DWDM
C. VPLS
D. DMVPN
Answer: B
Q15. Which statement describes the methodology that supports the Cisco Enterprise Architecture models?
A. It divides the network into functional network modules.
B. It divides the network into role-based network modules.
C. It divides the network into regional network modules.
D. It divides the network into operational network modules.
Answer: A
Q16. During which phase of the PPDIOO model would you conduct interviews with supporting staff to develop and propose a viable solution?
A. Prepare
B. Plan
C. Design
D. Implement
E. Operate
F. Optimize
Answer: A
Explanation:
Prepare Phase The Prepare phase establishes organization and business requirements, develops a network strategy, and proposes a high-level conceptual architecture to support the strategy. Technologies that support the architecture are identified. This phase creates a business case to establish a financial justification for a network strategy.
