What type of device connects multiple computers to the network, but
becomes less efficient as network traffic increases?
❍ A. Switch
❍ B. Hub
❍ C. Repeater
❍ D. Router

The Answer: B. Hub
A hub operates as a multi-port repeater, where incoming traffic is
repeated to every other port in the hub. If more than one device attempts
to communicate at the same time, these conflicting signals are called a
collision. Each time a collision occurs, the sending devices have to stop
transmitting, wait a random amount of time, and try sending the traffic
again. If many devices are sending large amounts of data, the overall
network efficiency will decrease as the number of collisions increase.

A network administrator would like to enable DHCP on a laptop, but
they would like the same IP address to be assigned to the laptop each
time it starts. Which of the following would provide this functionality?
❍ A. Create an IP reservation on the DHCP server
❍ B. Administratively configure the laptop’s MAC address
❍ C. Use APIPA addressing
❍ D. Assign the laptop to a static IP VLAN

The Answer: A. Create an IP reservation on the DHCP server
A DHCP (Dynamic Host Configuration Protocol) server will
automatically assign IP (Internet Protocol) addresses to devices on the
network from an available pool. This means that the IP address for a
device may change over time based on the addresses currently available
in the pool. To force the same IP address assignment each time, the
network administrator can create an IP reservation in the DHCP server
to associate a specific IP address to the MAC (Media Access Control)
address of the laptop.

❍ B. Install an additional hard drive
❍ C. Create a Windows Recovery Environment boot drive
❍ D. Upgrade the system RAM
❍ E. Install Windows guest VMs

The Answers: D. Upgrade the system RAM, and
E. Install Windows guest VMs
The easiest way to use multiple operating systems on a single machine
is to run them as virtual machines. Although 750 GB (Gigabytes) is
plenty of storage space for multiple virtual machines, the 4 GB of RAM
(Random Access Memory) on the host computer is too small to support
multiple Windows operating systems at the same time. Once the memory
upgrade is complete, it’s a relatively easy process to install the guest virtual
machines on the existing hard drive
