A small college uses VLAN 10 for the classroom network and VLAN 20 for the office network. What is needed to enable communication between these two VLANs while using legacy inter-VLAN routing?
A router with at least two LAN interfaces should be used.
A high school uses VLAN15 for the laboratory network and VLAN30 for the faculty network. What is required to enable communication between these two VLANs while using the router-on-a-stick approach?
A switch with a port that is configured as a trunk is needed when connecting to the router
Which two statements are true regarding switch port security? (Choose two.)
Dynamically learned secure MAC addresses are lost when the switch reboots. If fewer than the maximum number of MAC addresses for a port are configured statically, dynamically learned addresses are added to CAM until the maximum number is reached.

Enter the switchport access vlan 3 command in interface configuration mode.

on the half-duplex end of the connection
Which network device can serve as a boundary to divide a Layer 2 broadcast domain?
router
A network administrator issues the show vlan brief command while troubleshooting a user support ticket.
the VLAN assignment and membership for all switch ports
What does the term "port density" represent for an Ethernet switch?
the number of available ports
When configuring a router as part of a router-on-a-stick inter-VLAN routing topology, where should the IP address be assigned?
to the subinterface
Which two previously independent technologies should a network administrator attempt to combine after choosing to upgrade to a converged network infrastructure? (Choose two.)
user data traffic VoIP phone traffic
In which situation would a technician use the show interfaces switch command?
when packets are being dropped from a particular directly attached host
Match the functions to the corresponding layers. (Not all options are used.)
ACCESS LAYER: 1) Represents the network edge 2) Provides network access for user DISTRIBUTION LAYER: 1) Implements network access policy 2) establishes layer 3 boundaries CORE LAYER: 1) Provides high speed connectivity 2) Aggregator for all campus blocks
Math the borderless switched network guideline description to the principle. (Not all options are used.)
CONVERGENCE: FLEXIBILITY: HIERARCHICAL: MODULARITY:
What type of network uses one common infrastructure to carry voice, data, and video signals?
Converged
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?
Fixed Configuration
Which action will bring an error-disabled switch port back to an operational state?
Issue the shutdown and then no shutdown interface commands
A Cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port Fa0/5. What is the effect of issuing a switchport trunk allowed vlan 30 command on Fa0/5?
It allows only VLAN 30 on Fa0/5.
Where are dynamically learned MAC addresses stored when sticky learning is enabled with the switchport port-security mac-address sticky command?
RAM
A network administrator configures the port security feature on a switch. The security policy specifies that each access port should allow up to two MAC addresses. When the maximum number of MAC addresses is reached, a frame with the unknown source MAC address is dropped and a notification is sent to the syslog server. Which security violation mode should be configured for each access port?
Restrict
A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?
Segment the LAN into smaller LANs and route between them.
Which network device can be used to eliminate collisions on an Ethernet network?
Switch
Which statement describes a result after multiple Cisco LAN switches are interconnected?
The broadcast domain expands to all switches.
Which solution would help a college alleviate network congestion due to collisions?
a high port density switch
What is a basic function of the Cisco Borderless Architecture distribution layer?
aggregating Layer 3 routing boundaries
What is one function of a Layer 2 switch?
determines which interface is used to forward a frame based on the destination MAC address
What is a definition of a two-tier LAN network design?
distribution and core layers collapsed into one tier, and the access layer on a separate tier
What is a disadvantage of using router-on-a-stick inter-VLAN routing?
does not scale well beyond 50 VLANs
What is the effect of using the switchport port-security command?
enables port security on an interface
What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.)
to enhance user bandwidth to isolate traffic between segments
What is a function of the switch boot loader?
to provide an environment to operate in when the switch operating system cannot be found
When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?
Native VLAN ID
A production switch is reloaded and finishes with a Switch> prompt. What two facts can be determined? (Choose two.)
POST occurred normally. A full version of the Cisco IOS was located and loaded.
Which two statements are true about using full-duplex Fast Ethernet? (Choose two.)
Performance is improved with bidirectional data flow. Full-duplex Fast Ethernet offers 100 percent efficiency in both directions.
Port Fa0/11 on a switch is assigned to VLAN 30. If the command no switchport access vlan 30 is entered on the Fa0/11 interface, what will happen?
Port Fa0/11 will be returned to VLAN 1.
What is one difference between using Telnet or SSH to connect to a network device for management purposes?
Telnet sends a username and password in plain text, whereas SSH encrypts the username and password.
What happens to a port that is associated with VLAN 10 when the administrator deletes VLAN 10 from the switch?
The port becomes inactive.
What is a characteristic of legacy inter-VLAN routing?
The router requires one Ethernet link for each VLAN.

Which two characteristics match extended range VLANs? (Choose two.)

a combination of the functionality of the distribution and core layers

cut-through: appropriate for high performance computing applications may forward invalid frames forwarding process can begin after receiving the destination address store-and-forward: error checking before forwarding only forwards valid frames forwarding process only begins after receiving the entire frame
