CCNA 4 Chapter 7 V4.0
Labels: CCNA 4 Chapter 7 V4.0 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 networktraffic. Users within the enterprise are not affected by the test. Network response can be tested in unplanned and unpredictable situations. Unlikely failure conditions can be conveniently tested. Network response can be tested in a highly controlled simulated environment.

2 While preparing a network test plan document, a network designer records all initial and modified device configurations. Whichsection of the document typically contains this information? Appendix Test Procedures Test Description Actual Results and Conclusions Anticipated Results and Success Criteria

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? Test Description Test Procedures Design and TopologyDiagram

4 What OSI model Layer 2 security measure can a network engineer implement when prototyping network security? a firewall at the network edge port security at the access design layer port security at the distribution design layerIP access control lists 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. They select the functions that occur at the network core. They select the functions that do not exist in the existing network. They select the functions from a list of generic networkoperations.

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 S1 R3 S2 R5

S3

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.) Switch1 is the root bridge. Interface Fa0/2 on Switch1 has no role in the operation of spanning tree. 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 beenimplemented. Interface Fa0/1 on Switch1 is the forwarding port selected for the entire spanning-tree topology.

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

9 Refer to the exhibit. During prototype testing, verification of VLAN connectivity is being performed. Based on the informationshown, what command produced the output? show spanning-tree show interfaces trunk show cdp neighbors show interfaces

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 reconfigureswitch port Fa0/24? Use the switchport mode access command from interface configuration mode. Enter the switchport nonegotiate command from interface configuration mode. Administratively shut down and re-enable the interface to return it to the default. Enter the no switchport mode trunk command in interface configuration mode. Use the switchport access vlan vlan number command from interface...
