Q1. Which protocol is the recommended first-hop redundancy protocol for an existing infrastructure that contains multiple vendors and platforms?
A. HSRP
B. VRRP
C. IGRP
D. OSPF
Answer: B
Q2. Which three options are valid Cisco STP tools used to ensure best-practice access layer design for the enterprise campus? (Choose three.)
A. Port fast
B. UDLD
C. Root Guard
D. BPDU Guard
E. Flex Links
F. SPAN
G. Ether Channel
Answer: A,C,D
Explanation:
Access layer Limit VLANs to a single closet when possible to provide the most deterministic and highly available topology.
Use RPVST+ if STP is required. It provides the best convergence.
Set trunks to ON and ON with no-negotiate
Manually prune unused VLANs to avoid broadcast propagation.
Use VTP Transparent mode, because there is little need for a common VLAN database in hierarchical networks.
Disable trunking on host ports, because it is not necessary. Doing so provides more security and speeds up Port Fast.
Consider implementing routing in the access layer to provide fast convergence and Layer 3 load balancing.
Use Cisco STP Toolkit, which provides Port Fast, Loop Guard, Root Guard, and BPDU Guard.
Q3. Which three describe challenges that are faced when deploying an environment for teleworkers? (Choose three.)
A. supporting a mix of technically knowledgeable and nontechnical users
B. simplifying router installation and configuration
C. verifying available power at employee's house for necessary equipment
D. avoiding situations where employees might use nonstandard hardware or configurations
E. reducing daily commuting time to main office location
F. providing access to FTP servers located in main office location
G. implementing leased line connectivity between main office and employee's home location
Answer: A,B,D
Q4. An application uses broadcast traffic to send data to IPv4 hosts. How can the application communicate using IPv6?
A. Anycast
B. Unicast
C. Broadcast
D. Multicast
Answer: A
Q5. What significant advantage does EIGRP have over OSPF?
A. easy summarization
B. shorter convergence times
C. single area operation
D. low processor utilization
Answer: B
Q6. Which of the following three options represents the components of the Teleworker Solution? (Choose three.)
A. Cisco Unified IP Phone
B. Cisco 880 Series Router
C. Aironet Office Extend Access Point
D. Catalyst 3560 Series Switch
E. Cisco 2900 Series Router
F. MPLS Layer 3 VPN
G. Leased lines
Answer: A,B,E
Explanation:
A Cisco ASR is used to terminate Teleworker solutions, not a 2900 series router. Hybrid teleworker uses Aironet, Advanced teleworker uses 880, both use IP phones. google: "at_a_glance_c45-652500.pdf" for details
The Cisco Virtual Office Solution for the Enterprise Teleworker is implemented using the Cisco 800 series ISRs. Each ISR has integrated switch ports that then connect to the user’s broadband connection. The solution uses a permanent always-on IPsec VPN tunnel back to the corporate network. This architecture provides for centralized IT security management, corporate-pushed security policies, and integrated identity services. In addition, this solution supports the enterprise teleworker needs through advanced applications such as voice and video. For example, the enterprise teleworker can take advantage of toll bypass, voicemail, and advanced IP phone features not available in the PSTN.
Enterprise Teleworker Module
The enterprise teleworker module consists of a small office or a mobile user who needs to access services of the enterprise campus. As shown in Figure 2-14, mobile users connect from their homes, hotels, or other locations using dialup or Internet access lines. VPN clients are used to allow mobile users to securely access enterprise applications. The Cisco Virtual Office solution provides a solution for teleworkers that is centrally managed using small integrated service routers (ISR) in the VPN solution. IP phone capabilities are also provided in the Cisco Virtual Office solution, providing corporate voice services for mobile users.
Q7. Which two design approaches provide management of enterprise network devices? (Choose two.)
A. in-band
B. out-of-line
C. out-of-band
D. in-line
Answer: A,C
Q8. Which three terms describe the primary functions of the distribution layer of the campus network design hierarchy? (Choose three.)
A. provides end-user connectivity
B. provides high speed transport
C. provides QoS services
D. enforces security policies
E. provides WAN connections
F. connects access devices to the core backbone
Answer: C,D,F

Q9. Which two of the following are benefits of using a modular approach to network design? (Choose two.)
A. improves flexibility
B. facilitates implementation
C. lowers implementation costs
D. improves customer participation in the design process
Answer: A,B
Q10. Application servers require load balancing and security services. Where in the data center network should these services be provisioned?
A. core
B. aggregation
C. Layer 3 access
D. distribution
Answer: B
