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
#The test network experiences real-world network traffic.
#Network response can be tested in unplanned and unpredictable situations.
