IT 341 FINAL REVIEW QUESTIONS & VERIFIED
ANSWERS
What is one function of a Layer 2 switch? - Answers - aggregating Layer 3 routing
boundaries
What is a definition of a two-tier LAN network design? - Answers - distribution and core
layers collapsed into one tier, and the access layer on a separate tier
match the borderless switched network guideline to the principle.
allows intelligent traffic load sharing by using all network resources
allows seamless network expansion and integrated service enablement on an on-
demand basis
facilitates understanding the role of each device at every tier, simplifies deployment,
operation, management, and reduces fault domains at every tier
satisfies user expectations for keeping the network always on - Answers - flexibility
modularity
hierarchical
resiliency
What is a collapsed core in a network design? - Answers - a combination of the
functionality of the distribution and core layers
What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet
frames? (Choose two.) - Answers - ingress port
destination MAC address
match the forwarding characteristics to its type: - Answers - cut-through:
-may forward invalid frames
-appropriate for high performance computing applications
store-and-forward:
-error checking before forwarding
-forwarding process only begins after receiving the entire frame
,Which two features of the hierarchical design make it the better choice? - Answers - -
simpler deployment for additional switch equipment
-lower bandwidth requirements
Which two previously independent technologies should a network administrator attempt
to combine after choosing to upgrade to a converged network infrastructure? - Answers
- -VoIP phone traffic
-mobile cell phone traffic
A local law firm is redesigning the company network so that all 20 employees can be
connected to a LAN and to the Internet. The law firm would prefer a low cost and easy
solution for the project. What type of switch should be selected? - Answers - fixed
configuration
A ______________ network is one that uses the same infrastructure to carry voice,
data, and video signals. - Answers - converged
Refer to the exhibit. How many broadcast domains are displayed? - Answers - 8
Which network device can be used to eliminate collisions on an Ethernet network? -
Answers - switch
Which statement describes the microsegmentation feature of a LAN switch? - Answers -
Each port forms a collision domain.
What are two advantages of modular switches over fixed-configuration switches? -
Answers - increased scalability
need for fewer power outlets
How many collision domains are shown in the topology? - Answers - 2???
How is a frame sent from PCA forwarded to PCC if the MAC address table on switch
SW1 is empty? - Answers - SW1 floods the frame on all ports on SW1, excluding the
port through which the frame entered the switch.
match the functions to the corresponding layers - Answers - access layer:
-represents the network edge
-provides network access to the user
distribution layer:
-establishes Layer 3 routing boundaries
-implements network access policy
, core layer:
-provides high-speed backbone connectivity
-functions as an aggregator for all the campus blocks
Consider that the main power has just been restored. PC3 issues a broadcast IPv4
DHCP request. To which port will SW1 forward this request? - Answers - to Fa0/1,
Fa0/2, and Fa0/3 only
Which type of address does a switch use to build the MAC address table? - Answers -
source MAC address
What is the destination address in the header of a broadcast frame? - Answers - ???
What is a basic function of the Cisco Borderless Architecture distribution layer? -
Answers - providing access to end user devices???
What are two reasons a network administrator would segment a network with a Layer 2
switch? - Answers - to isolate traffic between segments
to enhance user bandwidth
The network administrator wants to configure Switch1 to allow SSH connections and
prohibit Telnet connections. How should the network administrator change the displayed
configuration to satisfy the requirement? - Answers - Modify the transport input
command.
Which statement describes the port speed LED on the Cisco Catalyst 2960 switch? -
Answers - If the LED is green, the port is operating at 100 Mb/s.
Match the link state to the interface and protocol status. - Answers - ???
Which action will bring an error-disabled switch port back to an operational state? -
Answers - Issue the shutdown and then no shutdown interface commands.???
identify the steps needed to configure a switch for SSH. - Answers - -generate RSA
keys
-use the transport input ssh command
-configure a domain name
-use the login local command
Open the PT Activity. Perform the tasks in the activity instructions and then answer the
question.
Which event will take place if there is a port security violation on switch S1 interface
Fa0/1? - Answers - Packets with unknown source addresses will be dropped.
