Class Alfa Bravo Charlie range of addresses
Alfa: 0 - 127
Bravo: 128 - 191
Charlie: 192 - 223
IPv6 addresses are made up of
eight hextets separated by colons
*Top-level: Second-level:
Top-level: .com .org .edu
Second-level: Microsoft.comWikipedia.org mit.edu
*The process of associating host names to IP addresses: Only ones that Windows support:
DNS WINS LLMNR (if first two fail) PNRP
The ______ command displays active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, IPv4 statistics (for the IP, ICMP, TCP, and UDP protocols), and IPv6 statistics (for the IPv6, ICMPv6, TCP over IPv6, and UDP over IPv6 protocols).
netstat
Used without parameters, netstat displays…
active TCP connections.
*Allows wireless clients to connect to each other without the use of a wireless access point (AP)
Ad hoc
Supports bandwidth up to 11 Mbps; uses the 2.5‐GHz
frequency; susceptible to interference with cordless
phones and microwaves operating in the same frequency;
WEP‐ and WPA‐supported.
802.11b
Supports bandwidth up to 54 Mbps; uses the 5‐GHz
frequency; less interference with common household
devices; higher frequency means shorter range compared
with 802.11b and also less apt to penetrate walls;
incompatible with 802.11b because they use different
frequencies; WEP‐ and WPA‐supported.
802.11a
*Supports bandwidth up to 54 Mbps; uses the 2.5‐GHz
frequency; backward compatible with 802.11b; 802.11g
was designed to use the best features of both 802.11b and
802.11a; WEP‐ and WPA‐supported.
802.11g
Security standard for 802.11 networks that use RADIUS
for authentication; provides key management; RADIUS
provides centralized authentication, authorization, and
accounting for remote connections.
802.1X
*It is a Microsoft implementation that uses ad hoc wireless networking that allows you to easily connect to another wireless device.
Wi‐Fi Direct
To use Wi‐Fi Direct with Windows 10, you would first create a
pairing between two devices, similarly to what you would do with Bluetooth
It is used when your computer is connected to its corporate domain and can authenticate to the domain controller through one of its connections.
A domain profile
It is used when your computer is connected to a private network location (home or small office network) and is located behind a firewall and/or a device that performs NAT. If you are using this profile with a wireless network, you should implement encryption (WPA v2).
A private profile
It is used when your computer is connected to a public network (for example, directly connected to the Internet). It is assigned to the computer when it is first connected to a new network; rules associated with this profile are the most restrictive.
A public profile
It is a new feature introduced with Windows 7 and
Windows Server 2008 R2. Provides seamless intranet connectivity to ________ client computers when they are connected to the Internet
Configuring DirectAccess
*_______ connections are automatically established and they provide always-on seamless connectivity
DirectAccess
Overcomes the limitations of VPNs by automatically establishing a bidirectional connection from client computers to the organization’s network using IPsec and Internet Protocol version 6 (IPv6)
DirectAccess Connection
FAT Maximum Partition Size, Maximum Size
2GB, 2GB
FAT32 Maximum Partition Size, Maximum Size
32GB, 4GB
NTFS Maximum Partition Size, Maximum Size
256TB, Limited by the size of the volume on which it resides
exFAT Maximum Partition Size, Maximum Size
128 PB, Limited by the size of the volume on which it resides
Allows for more partitions and larger volume sizes.
A GPT partition style
*A disk initialized as a GPT partition style may contain
up to 128 primary partitions. Each partition can be as large as 9.4 zettabytes (ZB). One zettabyte is equal to one billion terabytes.
Uses free space available on a single disk.
Simple volume
Extends a simple volume across multiple disks, up to a maximum of 32.
Spanned volume
Duplicates data from one disk to a second disk for redundancy and fault tolerance; if one disk fails, data can be accessed from the second disk. You cannot span a mirrored volume; a mirrored volume must reside on a single disk. Mirroring is also referred to as RAID‐1.
Mirrored volume
Stores data across two or more physical disks. Data on a striped volume is written evenly to each of the physical disks in the volume. You cannot mirror or span a striped volume. Striping is often referred to as RAID‐0.
Striped volume
Writes one copy of your data but doesn’t protect against drive failures; requires at least one drive.
Simple (no resiliency)
*Writes two copies of your data to protect against a single drive failure; requires at least two drives.
Two‐way mirror
