What international standard describes requirements for an information security management system (ISMS)?

What international standard describes requirements for an information security management system (ISMS)?

• GDPR
• ISO/IEC 27001
• ISO/IEC 27000
• ISO/IEC 27002  

EXPLANATION

"Standards aren’t the same as regulations and following a standard doesn’t guarantee that you’re within the relevant laws."

GDPR is a data privacy law/regulation created by the European Union (EU). It has an "extra-territorial effect" to protect data belonging to EU citizens and residents. This not only applies to EU-based organizations but also that in another region, which target or collect data related to people from European Economic Area (EEA).

ISO 27000 has an overview of ISMS and it contains terms and definitions.
ISO 27002 has guidelines and it's optional. However, there are useful tips related to the implementation of controls and requirements, which are provided in ISO 27001.

What is commonly used to convert DHCP broadcast messages to unicast messages and forward them to DHCP servers on a separate subnet?

What is commonly used to convert DHCP broadcast messages to unicast messages and forward them to DHCP servers on a separate subnet?

• DHCP Relay Agent
• DHCP Reservation
• DHCP Filter
• DHCP Forwarder         

EXPLANATION

Generally, DHCP messages are broadcasted. So, in order for the messages to be exchanged between a DHCP client (PC) and DHCP server, both the client and server have to reside on the same subnet. That is because routers do not forward any broadcast IP packet (i.e. one with a destination MAC address of FF:FF:FF:FF:FF:FF and a destination IP address of 255.255.255.255) to other interfaces. Thus, a broadcast DHCP packet sent by a DHCP client cannot be delivered to DHCP server(s) on different subnet(s) through a router.

To address this problem, the concept of a DHCP relay agent has long been adopted.  The core function of this DHCP relay agent is to convert broadcast DHCP packets into unicast messages and then forward them to DHCP servers

Which version of Windows introduced the Metro user interface, which can be used on desktops, laptops, mobile phones, and tablets?

Which version of Windows introduced the Metro user interface, which can be used on desktops, laptops, mobile phones, and tablets?

• Windows XP
• Windows 8
• Windows 7
• Windows Vista           

EXPLANATION

Metro is a new “design language” of Microsoft. A new concept aimed at changing the logic of construction and work of the operating system and applications, as well as the scheme of interaction between the user and the electronic device.

The basic principles of construction and appearance were largely borrowed from the information systems of transport nodes. The inscriptions and graphical elements in these systems are subject to quite specific requirements: very high readability and visual perceptibility of information, absence of unnecessary distractions, clean and clear view of all external elements.
