Correct Answer: A

When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is 100 meters or 328 feet.

Correct Answer: B

HTTPS, which stands for Hypertext Transfer Protocol Secure, makes it more difficult for hackers, the NSA, and others to track users. The protocol makes sure the data isn't being transmitted in plain-text format, which is much easier to eavesdrop on.

Correct Answer: B

The Lightweight Directory Access Protocol (LDAP) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network.

Correct Answer: A

Telnet, by default, does not encrypt any data sent over the connection (including passwords), and so it is often practical to eavesdrop on the communications and use the password later for malicious purposes; anybody who has access to a router, switch, hub or gateway located on the network between the two hosts where Telnet is being used can intercept the packets passing by and obtain login, password and whatever else is typed with a packet analyzer.

Correct Answer: D

127.0.0.1 is the IPv4 loopback address.

Correct Answer: B

Incorrect:

The private address space specified in RFC 1918 is defined by the following three address blocks:

not A: 192.168.0.0/16

The 192.168.0.0/16 private network can be interpreted either as a block of 256 class C network IDs or as a 16-bit assignable address space (16 host bits) that can be used for any subnetting scheme within the private organization. The

192.168.0.0/16 private network allows the following range of valid IP addresses: 192.168.0.1 to 192.168.255.254.

Not C:

10.0.0.0/8

The 10.0.0.0/8 private network is a class A network ID that allows the following range of valid IP addresses: 10.0.0.1 to 10.255.255.254. The 10.0.0.0/8 private network has 24 host bits that can be used for any subnetting scheme within the

private organization.

Not D:

172.16.0.0/12

The 172.16.0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any subnetting scheme within the private organization. The

172.16.0.0/12 private network allows the following range of valid IP addresses: 172.16.0.1 to 172.31.255.254.

Correct Answer: AD

Hubs repeat everything they receive and can be used to extend the network.

Switches control the flow of network traffic based on the address information in each packet. A switch learns which devices are connected to its ports (by monitoring the packets it receives), and then forwards on packets to the appropriate port

only. This allows simultaneous communication across the switch, improving bandwidth.
