Question 1

What is the purpose of the secure tab on a switch?&#10;A)The switchport will use port discovery to assign a MAC address to the port.&#10;B)The switchport will automatically disable itself if a device with a different MAC address connects to the port.&#10;C)The switchport will use a different MAC address than the one connected to the port and will automatically enable itself.&#10;D)This enables the switch to select which networking devices have a selectable IP address.

Accepted Answer

The purpose of the secure tab on a switch is to enable port security. When this feature is enabled on a switchport, it will automatically disable the port if a device with a different MAC address connects to the port. This prevents unauthorized devices from accessing the network.

Question 2

The logical address is another name for a MAC address.True or False?

Accepted Answer

The logical address is an IP address, while the MAC address is a physical address.

Question 3

A multicast is characterized by which of the following&#10;A)It uses Class D addressing.&#10;B)It uses class C addressing.&#10;C)It is used when messages are sent to a specific group of networking devices.&#10;D)None of these answers are correct.

Accepted Answer

Multicast is a type of network communication in which a single message is sent to a group of destination devices. It uses Class D addressing and is used when messages are sent to a specific group of networking devices.

Question 4

A broadcast can cause a network slow-down.True or False?

Accepted Answer

A broadcast is a transmission of data that is sent to every device on a network, which can cause congestion and slow down the network.

Question 5

What is the length of time an IP address is assigned to a switchport called?&#10;A)Delay time&#10;B)Enable time&#10;C)Aging time&#10;D)Access time

Accepted Answer

The length of time an IP address is assigned to a switchport is called aging time. This is the period of time for which the switch will keep the mapping between the IP address and the switchport in its CAM table before discarding it.

Question 6

Which of the following terms is used to describe that a MAC address has been manually assigned?&#10;A)Dynamic assignment&#10;B)ARP assignment&#10;C)DHCP assignment&#10;D)Static assignment

Accepted Answer

Static assignment is the term used when a MAC address is manually assigned.

Question 7

The network address is another name for a layer 4 address.True or False?

Accepted Answer

The network address is a name for a layer 3 address, not layer 4. Layer 4 addresses refer to port numbers.

Question 8

Which of the following devices interconnects two LANs running the same type of networking protocol?&#10;A)Protocol bridge&#10;B)Transparent switch&#10;C)Transparent bridge&#10;D)Protocol hub

Accepted Answer

A transparent bridge is used to interconnect two LANs running the same type of networking protocol. It operates at the data link layer (layer 2) of the OSI model and uses MAC addresses to forward packets between LANs. Options A and D are incorrect as they refer to a protocol bridge and protocol hub which are not used for interconnecting LANs running the same networking protocol. Option B, a transparent switch, may also interconnect two LANs running the same type of networking protocol but it is a higher-end device compared to a transparent bridge and is typically used in larger networks with higher levels of traffic.

Question 9

The list of MAC addresses and port locations for hosts connected to the bridge ports is called an association table.True or False?

Accepted Answer

The list of MAC addresses and port locations for hosts connected to the bridge ports is called a MAC address table or CAM table (Content Addressable Memory), not an association table.

Question 10

The AUI port is used to connect which of the following&#10;A)100Mbps Ethernet&#10;B)10Mbps Ethernet&#10;C)1000Mbps Ethernet&#10;D)All of these answers are correct.&#10;E)None of these answers are correct.

Accepted Answer

The AUI (Attachment Unit Interface) port is an older interface primarily used for connecting to 10Mbps Ethernet networks. It cannot be used for connecting to 100Mbps or 1000Mbps Ethernet networks. Therefore, option B is the correct choice.

Question 11

Which of the following terms is used to describe that the MAC address is assigned when a host is connected?&#10;A)ARP assignment&#10;B)DHCP assignments&#10;C)Dynamic assignment&#10;D)Static assignment

Accepted Answer

The answer of Which of the following terms is used...

Question 12

A temporary storage of MAC addresses recently contacted is called which of the following&#10;A)ARP cache&#10;B)ARP file&#10;C)RARP cache&#10;D)ARP table

Accepted Answer

The answer of A temporary storage of MAC addresses recently...

Question 13

An association indicates that the destination address is for a networking device connected to one of the hub ports.True or False?

Accepted Answer

The answer of An association indicates that the destination address...
