A. Highly-controlled and simulated environment
B. Requires real-world network traffic
C. Not as easily controlled as a prototype network
D. High visibility and risk
E. Flexibility and manageability

2. When building a prototype to test a network design why is it important to create a test plan before beginning the process?
A. To ensure that the goals of the test are clear and measurable
B. To record a baseline of network activity on the production network
C. To provide a step-by-step guide for implementation of the network design
D. To ensure that network resources are adequate to support additional traffic generated by the test

3. Match the testing tool or command with its corresponding purpose

Testing Tool
A. Arp commands
B. Debug commands
C. Ping commands
D. Software logging
E. Show commands
F. Telnet commands
G. Traceroute commands

Purpose
1. Provides current state of route tables
2. Provides real time analysis
3. Verifies Layer 3 connectivity
4. Confirms reachability
5. Supports trend analysis
6. Allows terminal sessions on remote devices
7. Shows Layer 2 to Layer 3 connectivity

4. What is a common way of load balancing traffic over redundant links?
A. EtherCnannel
B. STP
C. Enequal cost routed links
D. Separate ISP connections

5. A network administrator is testing the redundant links between switches. What state will the redundant link search after the active link is disconnected?
A. Blocking
B. Forwarding
C. Listening
D. Learning
E. Disabled

6. A network designer wishes to add another server to the current network. What risk does the designer avoid by implementing two servers?
A. Limited scalability
B. Large failure domain
C. Possible bottlenecks
D. Single point of failure

7. A new company will have several buildings and use the network for voice, video and data. Two proposals have been made:
1. Use a flat switched network design to connect all the buildings and a single router for Internet access.
2. Use a hierarchical infrastructure with switches at the Access Layer and routers for data transport between buildings and Internet access. 
Which statement about the company designs is correct?
A. Proposal 1 meets all design goals.
B. Proposal 2 meets all design goals
C. Proposal 2 is only adequate for data traffic
D. Proposal 1 works well for video, but not VoIP.

8. Which Cisco switching protocol provides resiliency when a network experiences connectivity problems and ensures near 100% uptime?
A. VTP
B. RSTP
C. BPDU
D. EIGRP

9. A web content hosting company has been granted a new contract to host an online ordering service for a large retail chain. The content hosting company asks a networking consulting firm to examine the current network infrastructure to prepare for the launch of the online ordering service. The examination reveals that the content hosting company has two T1 lines connected to two separate ISPs. The server farm provides each customer with separate web server. Each server is running Linux with Apache on one 30-gigabyte hard disk.
What are the two greatest potential risks in the current network infrastructure of the content hosting company? (Choose two.)
A. Single point of failure of the web server
B. Large failure domain if the web server fails
C. Potential bottlenecks on the Internet connection
D. Single point of failure if their IPS fails to provide the connection
E. Limited scalability of web servers due to their hard disk capacity

10. Refer to the exhibit. Port Fa0/0 on router R1 is connected to port Fa0/1 on switch S1. After the commands shown are entered on both devices, The Network administrator determines that the devices on VLAN2 are unable to ping the devices on VLAN5
What is the likely problem?

Exhibit
R1(config)#interface fa0/0.1
R1(config-subif)#encapsulation dotlQ 2
R1(config-subif)#ip address 10.1.1.1 255.255.255.0
R1(config-subif)#exit
R1(config)#interface fa0/0.2
R1(config-subif)#encapsulation dotlQ5
R1(config-subif)#ip address 10.1.2.1 255.255.255.0
R1(config-subif)#end

S1(config)#interface fa0/1
S1(ocnfig-if)#switchport access vlan 2
S1(config-if)#switchport access vlan 5
S1(config-if)#no shutdown

A. S1 is not configured for trunking.
B. R1 does not have the VLANs entered in the VLAN database.
C. Spanning Tree Protocol is blocking port Fa0/0 on R1.
D. The VLANs do not match the subinterface numbers.
