Which of the following Ethernet standards always uses the RJ-45 connector for wired network connections?

100BaseT is Fast Ethernet, which uses twisted pair cabling and RJ-45 connectors

. Which of the following wireless standards uses the 2.4 GHz range and specifies throughput up to 54 Mbps?

802.11g is used to provide higher rates of speed on the same frequency as 802.11b, thus making it backward compatible.

.The network technology that provides IP addresses to clients in a configurable time period is known as what?

DHCP is used to assign IP addresses to clients automatically when they boot, and those addresses are given for a specific period of time known as a lease

Which of the following Internet technologies is becoming very popular and allows for segmented traffic through a dedicated line to the home or business?

Digital Subscriber Line is the direct connection that provides high-speed internet connectivity.

Which of the following is a system that provides host name resolution to IP addresses so that user-friendly domain and computer names can be used for network and Internet communication

Domain Name System is used to resolve names to IP addresses.

Which of the following is not a difference between hubs and switches?

Even a switch will still send broadcasts out all ports instead of to individual hosts as they do not create separate broadcast domains.

.Which of the following application layer protocols provides access to web pages throughout the Internet

Hypertext Transfer Protocol (HTTP) is used to traverse the World Wide Web and access pages.

Which of the following cable types is characterized by having very little susceptibility to electro-magnetic interference (EMI)

In fact, Fiber has zero susceptibility to EMI because it is not copper wire and doesn't send electrical signals; it instead uses light-based signals

Ethernet cabling specifications come in categories. Which category is required for Gigabit Ethernet?

In order to implement Gigabit Ethernet you need at least Cat 5e cabling

You would like to assign private IP addresses to all clients on the LAN and share a single IP address to access the Internet from every machine. Which networking technology is required?

Network Address Translation is used to grant access through a single public IP while private IP addresses are used internally.

7. Which of the following network devices is commonly used for the connection to the Internet in corporate networks that works with network layer protocols and packet forwarding

Routers are used to connect different network segments and ensure that packets can be routed between them.

The TCP/IP protocol provides addressing and routing using 32-bit IP addresses assigned to host computers. Which of the following additional TCP/IP settings provides access to external networks

The default gateway is your way off your local network segment and is used to provide remote network access including the Internet

5.A network device of this type provides the ability to cache outgoing requests for web pages in a cache that is available to multiple client computers. What is it

The proxy server provides NAT functionality as well as access control and caching functions

Which of the following network topologies is the most popular in modern networks?

This allows a direct connection for all systems and does not suffer the same disadvantages as physical rings and bus networks.

Which of the following is not required in order to access a local area network?

You only need wireless network cards in order to access a wireless network, not any network in general.
