You have been tasked with the creation and design of a network that must support a minimum of 5000 hosts. Which network accomplishes this goal?

10.3.0.0/19

Given a host IP address of 172.16.1.154 and a subnet mask of 255.255.254.0, what is the network ID for this host?

172.16.0.0

An IP address of 192.168.18.73/28 has what network ID?

192.168.18.64

By default, when using classful addressing, how many bits exist in the host portion of a Class A address?

24

A network with a CIDR notation of /26 would have what subnet mask?

255.255.255.192

How large is the 802.1Q tag that is added to an Ethernet frame when using VLANs?

4 bytes

What IEEE standard specifies how VLAN information appears in frames and how switches interpret that information?

802.1Q

When using IPv6, what would a /64 network likely be assigned to?

A smaller organization or business.

Which of the following suggestions can help prevent VLAN hopping attacks on a network?

Disable auto trunking and move native VLANs to unused VLANs.

When an 802.1Q tag is added to an Ethernet frame, where is it placed?

It is inserted between the source address and the Ethernet type field.

What does the VLAN Trunk Protocol (VTP) do?

It shares VLAN database information amongst switches that participate.

Subtracting an interesting octet value from 256 yields what number?

Magic number

With VTP, where is the VLAN database stored?

On the switch that is known as the stack master.

You are working on a Cisco switch and need to learn what VLANs exist on the switch. Which command will list the current VLANs recognized by the switch?

Show vlan

Which of the following statements regarding IPv6 subnetting is NOT accurate?

The largest IPv6 subnet capable of being created is a /64.

If the EUI-64 standard is used, what part of an IPv6 address is affected?

The last four blocks of the address.

In an IPv6 address, what do the first four blocks or 64 bits of the address represent?

The site prefix or global routing prefix.

In order to identify the transmissions that belong to each VLAN, a switch will add a tag to Ethernet frames that identifies the port through which they arrive at the switch.

True

When dealing with a Cisco switch, what is NOT one of the pre-established VLANs?

VLAN 1001

An interface that manages traffic from multiple VLANs is known by what term?

aggregation port

A native VLAN mismatch occurs when two access ports that are connected to each other are both tagging traffic with different VLAN IDs.

false

An unmanaged switch can still support the creation of VLANs, provided there is an interface for configuration.

false

On certain Cisco products, what command can be used to create and send helper messages that support several types of UDP traffic, including DHCP, TFTP, DNS, and TACACS+?

ip helper-address

What command will set the native VLAN on a Juniper switch port?

set native-vlan-id

A /24 CIDR block is equivalent to a 255.255.255.0 subnet mask.

true

By default, the native VLAN is the same as the default VLAN.

true

IPv6 addressing does not utilize classful addressing, therefore every IPv6 address is classless.

true

A subnet of 255.255.248.0 can be represented by what CIDR notation?

/21
