CCNA 2 V6.0 Chapter 4 (SYC)
Which statement describes a result after multiple Cisco LAN switches are interconnected?
The broadcast domain expands to all switches.
Which type of address does a switch use to build the MAC address table?
source MAC address
Which network device can be used to eliminate collisions on an Ethernet network?
switch
Represents the network edge Provides network access to the user
Access layer
Which two statements correctly describe the concepts of administrative distance and metric?
Administrative distance refers to the trustworthiness of a particular route Routes with the smallest metric to a destination indicate the best path
What is a basic function of the Cisco Borderless Architecture distribution layer?
Aggregating Layer 3 routing boundaries perform routing between different VLANs
Provides high-speed backbone connectivity Functions as an aggregator for all the campus blocks
Core layer
Implements network access policy Establishes Layer 3 routing boundaries
Distribution layer
A hierarchical design for switches
Helps network administrators when planning and deploying a network expansion, Performing fault isolation when a problem occurs. Providing resiliency when traffic levels are high
facilitates understanding the role of each device at every tier, simplifies deployment, operation, management, and reduces fault domains at every tier
Hierarchical
In order for packets to be sent to a remote destination, what three pieces of information must be configured on a host?
IP address subnet mask default gateway
What are two advantages of modular switches over fixed-configuration switches?
Increased scalability Need for fewer power outlets
What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames?
Ingress port Destination MAC address
What are two reasons a network administrator would segment a network with a Layer 2 switch?
To enhance user bandwidth To isolate traffic between segments
Which solution would help a college alleviate network congestion due to collisions?
a high port density switch (A high port density switch provides very fast connectivity for many devices.)
When a computer is pinging another computer for the first time, what type of message does it place on the network to determine the MAC address of the other device?
an ARP request
A _________ network is one that uses the same infrastructure to carry voice, data, and video signals.
converged
What is one function of a Layer 2 switch?
determines which interface is used to forward a frame based on the destination MAC address*
A good hierarchical design has:
redundancy so one switch does not cause all networks to be down.
