1 A network engineer has decided to pilot test a portion of a new network design rather than rely on a prototype for proof-of-concept. What are two advantages of pilot testing a design concept?(Choose two.)
#The test network experiences real-world network traffic.
#Network response can be tested in unplanned and unpredictable situations.

2 While preparing a network test plan document, a network designer records all initial and modified device configurations. Which section of the document typically contains this information?
#Appendix

3 Refer to the exhibit. A network designer creates a test plan that includes the specification shown. In which section of the test plan would this specification be found?
#Anticipated Results and Success Criteria

4 What OSI model Layer 2 security measure can a network engineer implement when prototyping network security?
#port security at the access design layer

5 How do designers decide which network functions need to be included in the prototype test?
#They select the functions that align with the business goals.

6 Refer to the exhibit. During prototype testing of the Cisco network shown, connectivity must be verified. Assuming all connections are working and CDP is enabled on all devices and interfaces, on which device was the command issued?
#R1

7 Refer to the exhibit. During prototyping, Layer 2 functionality is being tested. Based on the output shown, which two pieces of information can be determined? (Choose two.)
#Interface Fa0/2 on Switch1 is the alternate port used to reach the root bridge.
#Based on the entries in the "Role" column, it can be concluded that RSTP has been implemented.

8 What Rapid Spanning Tree Protocol (RSTP) state is given to the forwarding port elected for every switched Ethernet LAN segment?
#designated

9 Refer to the exhibit. During prototype testing, verification of VLAN connectivity is being performed. Based on the information shown, what command produced the output?
#show interfaces trunk

10 Switch port Fa0/24 was previously configured as a trunk, but now it is to be used to connect a host to the network. How should the network administrator reconfigure switch port Fa0/24?
#Use the switchport mode access command from interface configuration mode.

11 Refer to the exhibit. The redundant paths are of equal bandwidth and EIGRP is the routing protocol in use. Which statement describes the data flow from Server to PC2?
#EIGRP load balances across the R3 to R1 and R3 to R2 links.

12 A network designer needs to determine if a proposed IP addressing scheme allows efficient route summarization and provides the appropriate amount of scalability to a design. What is useful for validating a proposed hierarchical IP addressing scheme?
#a network simulator

13 In the router command encapsulation dot1q 10, what does the number 10 represent?
#the number of the VLAN associated with the encapsulated subinterface

14 Refer to the exhibit. The users on the 192.168.10.192 network are not allowed Internet access.The network design calls for an extended ACL to be developed and tested. Where should the
ACL be placed for the least effect on other network traffic?
#inbound on Fa0/1 of R3

15 Refer to the exhibit. What two measures can be taken to address the areas of weakness circled in the network design? (Choose two.)
#Add a switch in the server block connecting the server farm to each core switch.
#Provide a redundant firewall router connecting to a second ISP, the core switches, and the DMZ.

16 Why is it important to record baseline measurements of a prototype network?
#Test results are compared to the baseline to see how the test conditions increase processor use or decrease available bandwidth.

17 Refer to the exhibit. A network administrator has been given the task of creating a design for a temporary classroom building that is to be set up outside an overcrowded school. In testing the prototype, it is found that the student PC cannot ping the teacher PC. All the switch interfaces are active and connected properly, as is interface Fa0/0 of the router. Given that only the commands shown have been added to the router configuration, what is the source of the problem?
#The IP settings on the student PC are incorrect.

18 Refer to the exhibit. Why are interfaces Fa0/11, Fa0/23, and Fa0/24 not shown in this switch output?
#Interfaces Fa0/11, Fa0/23, and Fa0/24 are trunks.

19 Refer to the exhibit. A network technician is performing an initial installation of a new switch in the east wing. The technician removes the switch from the box, makes the connections to the network, and adds the configuration shown. The technician notifies the network administrator that the switch has been installed. When the network administrator at the home office attempts to telnet to the switch from host 192.168.0.1, the connection fails. What action should the network
technician take?
#Add a default gateway to the switch configuration.

20 Refer to the exhibit. After all the interfaces have stabilized, what is the spanning-tree state of all the enabled interfaces of SW11?
#forwarding
