Which formulas can be used to calculate the magic number? Choose two.

• 256 – the interesting octet
• 2h – 2
• 2n
• 2h

How many bits of a Class A IP address are used for host information?

• 8 bits
• 32 bits
• 24 bits
• 16 bits

Which IEEE standard determines how VLANs work on a network?

• 802.11
• 802.1Q
• 802.3af
• 802.1x

Which port mode on a switch enables that port to manage traffic for multiple VLANs?

• Ethernet

• Trunk
• Access

What is the formula for determining the number of possible hosts on a network?

• 2h = Z
• 2n = Y

Which of the following is not a good reason to segment a network?

• To narrow down the location of problems on a network
• To increase the number of networking devices on a network
• To reduce the demand on bandwidth
• To limit access to broadcast domains

What do well-chosen subnets accomplish?

• Routing efficiency is decreased by ensuring IP address spaces are not mathematically related.
• IP address spaces overlap for easier management.
• Network documentation is easier to manage.
• Problems affect the entire network, making them more difficult to pin down.

Which hexadecimal block in an IPv6 address is used for the Subnet ID?

• The first one
• The fourth one
• The third one

• Eight
• Ten
• Nine
• None

While designing your network’s VLAN topology, your team has decided to use a centrally managed DHCP server rather than creating a separate DHCP server for each VLAN. What software will you need to make the central DHCP server accessible across VLANs?
