Complete Question:
1. A wireless technology standard for exchanging data over short distances
2. A particular brand of mobile phone/PDA
3. A network that operates over a limited distance, usually for one or a few users
1. Bluetooth
2. PAN
3. Blackberry
Answer:
1. Bluetooth 2. Blackberry . 3. PAN
Explanation:
1. Bluetooth is a wireless technology standard, used in order to exchange data between mobile devices, like smartphones, tablets, headsets, wearables, over short distances in a one-to-one fashion (which means that it is not possible to build a network based in Bluetooth).
2. Blackberry is a brand of mobile phones/PDAs, very popular a decade ago, because it was the first one to allow mobile users to access e-mails and messages from anywhere, at any time.
3. PAN (Personal Area Network) is an ad-hoc network that it is only available for data exchange at a very short distance, within the reach of a person, i.e. a few meters as a maximum.
It is thought to allow someone to interact with his nearest environment (laptop, tablet, PDA) and it can be wireless (like Bluetooth) or wired (via USB cables).

Answer:
C. Aggregation switch.
Explanation:
Aggregation switch is a type of switch used to combine multiple network connections into a single link.
In Computer Networking, Aggregation switches are primarily designed to be used for connecting the Top-of-Rack (ToR) switches to a core switch or router, as the case may be.
Generally, the core switch is typically placed at the top of the data center network architecture topology.
An aggregation switch is usually designed to be large in size and has a lot of interfaces or ports for the connection of multiple networks into a single logical link.
<em>Additionally, the connections are mainly done in parallel in order to prevent total downtime or redundancy in a network, as well as to enhance the throughput than what is obtainable in a single network. </em>
