Q:

Which of the following atoms has the largest radius?

A) Br B) K
C) Na D) Cl
 
Answer & Explanation Answer: B) K

Explanation:

For neutral atoms, the periodic trends in atomic size can be described like this

Atomic size decreases when going from left to right across a period,
Atomic size increases when going from top to bottom down a group.

 

Let's use these trends to try and figure out which atom would have the largest radius.

If you look at elements that are located in the same group, potassium will have a larger atomic radius when compared with sodium. Likewise, bromine will have a larger atomic radius when compared with chlorine.

Now focus on potassium and bromine. Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.

Q:

What does a VLAN do?

A) Breaks up broadcast domains in a layer 2 switch internetwork B) Provides multiple broadcast domains within a single collision domain
C) Provides multiple collision domains on one switch port D) Acts as the fastest port to all servers
 
Answer & Explanation Answer: A) Breaks up broadcast domains in a layer 2 switch internetwork

Explanation:

virtual LAN (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). LAN is the abbreviation for local area network and in this context, virtual refers to a physical object recreated and altered by additional logic.

VLANs work by applying tags to network packets and handling these tags in networking systems – creating the appearance and functionality of network traffic that is physically on a single network but acts as if it is split between separate networks. In this way, VLANs can keep network applications separate despite being connected to the same physical network, and without requiring multiple sets of cabling and networking devices to be deployed.
