A server administrator tests an application migration from a 32-bit server to a 64-bit
server, but the application is still 32-bit. Where will Windows run the application?

WOW
In 64-bit Windows, the applications run within a special application
environment called WOW64 (Windows on Windows 64-bit). This
environment replicates the 32-bit environment expected by the application
and translates its requests into ones that can be processed by the 64-bit
CPU, memory, and file subsystems
User Account Control (UAC)

loads only basic drivers and services required to start the system.
This is a useful troubleshooting mode as it isolates reliability or
performance problems to add-in drivers or application services and rules
out having to fully reinstall Windows
Whaling
Give this one a try later!
Whaling is an attack directed specifically against upper levels of
management in the organization (CEOs and other "big catches"). Upper
management may also be more vulnerable to ordinary phishing attacks
because of their reluctance to learn basic security procedures.
ping Command

, cross-platform command-line diagnostic tool for testing IP packet
transmission.
The following steps outline the procedures for verifying a computer's
configuration & for testing router connections:
1. Ping the loopback address to verify TCP/IP is installed and loaded
correctly (ping 127.0.0.1)- the loopback address is a reversed IP address
used for testing purposes
2. Ping the IP address of your workstation to verify it was added correctly
and to check for possible duplicate IP addresses
3. Ping the IP address of the default gateway to verify it is up and running
and that you can communicate with a host on the local network
4. Ping the IP address of a remote host to verify you can communicate
through the router

Cloud-based SSO service allowing users to synchronize settings between
multiple Windows devices
Evil Twin Attack
Give this one a try later!
An evil twin attack is similar to phishing but instead of an email, the attacker
uses a rogue wireless access point to try to harvest credentials. An evil twin
might have a similar network name (SSID) to the legitimate one, or the
attacker might use some denial of service (DoS) technique to overcome the
legitimate AP.
The evil twin might be able to harvest authentication information from users
entering their credentials by mistake. For example, the evil twin might allow
devices to connect via open authentication and then redirect users' web
, browsers to a spoofed captive portal that prompts them for their network
password
Dynamic Disks

Key NTFS feature. The disk management feature allows space on multiple
physical disks to be combined into volumes
FAT32 (File Allocation Table)

32-bit file system used principally for system partitions and removable
media.
Does not support any of the reliability or security features of NTFS.
A server administrator wants to keep up with security patches and points their
machines to pull updates. What should the administrator point towards?

Repositories
Copies of distribution packages (including any updates) will be posted to a
software repository. Often the vendor will maintain different repositories. It
can then be used to install, uninstall, or update the software.
