Layer 4 of the TCP/IP model is the transport layer, which is responsible for providing reliable and efficient data transmission between hosts. The transport layer can use different protocols, such as TCP or UDP, depending on the requirements of the application. The transport layer also performs functions such as segmentation, acknowledgement, flow control, and error recovery. 1

The transport layer of the TCP/IP model corresponds to three layers of the OSI model: the transport layer, the session layer, and the presentation layer. The session layer of the OSI model manages the establishment, maintenance, and termination of sessions between applications. The session layer also provides services such as synchronization, dialogue control, and security. The presentation layer of the OSI model handles the representation, encoding, and formatting of data for the application layer. The presentation layer also performs functions such as compression, encryption, and translation. 23

802.11ax, also known as Wi-Fi 6, is an internet of things (IoT) connectivity technology that operates on the 2.4GHz and 5GHz bands, as well as all bands between 1 and 6GHz when they become available for 802.11 use, at ranges up to 11 Gbit/s. 802.11ax is designed to improve the performance, efficiency, and capacity of wireless networks, especially in high-density environments such as smart homes, smart cities, and industrial IoT. 802.11ax uses various techniques such as orthogonal frequency division multiple access (OFDMA), multi-user multiple input multiple output (MU-MIMO), target wake time (TWT), and 1024 quadrature amplitude modulation (QAM) to achieve higher data rates, lower latency, longer battery life, and reduced interference for IoT devices.

Security Operations (SecOps) is the process of coordinating and aligning security teams and IT teams to improve the security posture of an organization. SecOps involves implementing and maintaining security controls, technologies, policies, and procedures to protect the organization from cyber threats and incidents. When dealing with a known attack, SecOps must take the following action: document, monitor, and track the incident. This action is important because it helps SecOps to:

* Record the details of the attack, such as the source, target, impact, timeline, and response actions.

* Monitor the status and progress of the incident response and recovery efforts, as well as the ongoing threat activity and indicators of compromise.

* Track the performance and effectiveness of the security controls and technologies, as well as the lessons learned and improvement opportunities. Reference:

Answer : A

NAT stands for Network Address Translation, which is a process that allows devices on a private network to communicate with devices on a public network, such as the Internet. NAT translates the private IP addresses of the devices on the private network to public IP addresses that can be routed on the public network. This way, multiple devices on the private network can share a single public IP address and access the Internet. NAT also provides security benefits, as it hides the internal network structure and IP addresses from the outside world.

Answer : A

According to the NIST definition of cloud computing, Infrastructure as a Service (IaaS) is a cloud service model that provides ''the capability to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications''1.The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls)1.In other words, IaaS gives the user access to cloud-hosted physical and virtual servers, storage, and networking, as stated in the question.Reference:1: SP 800-145, The NIST Definition of Cloud Computing | CSRC2

Answer : C

If an endpoint does not know how to reach its destination, it will send data to the specified default gateway. A default gateway is a device that routes traffic from a local network to other networks or the internet. The endpoint will use the default gateway's IP address as the next hop for packets that are destined for unknown or remote networks. The default gateway will then forward the packets to the appropriate destination or another gateway, based on its routing table.Reference:
