DHCP scope exhaustion occurs when the number of available IP addresses to be leased from a DHCP server have been used up. This could be caused by a large number of clients on the network, or a misconfigured DHCP scope. When this happens, clients will be assigned an IP address from the APIPA range (169.254.0.0 to
169.254.255.255). To resolve this issue, the DHCP scope needs to be expanded or adjusted to accommodate the number of clients on the network.

* A hybrid cloud is a cloud deployment model that combines two or more different types of clouds, such as public, private, or community clouds12. A hybrid cloud allows an organization to leverage the benefits of both types of clouds, such as scalability, cost-efficiency, security, and control34.
* In the scenario, the company uses a private cloud to host its data center at its corporate office, which ensures greater control over the security of sensitive data. A private cloud is a cloud deployment model
* that is exclusively used by a single organization and is usually hosted on-premises or by a third-party provider12. A private cloud offers the highest level of security, privacy, and customization, but also requires more resources and maintenance34.
* During times when there are increased workloads, some of the company's non-sensitive data is shifted to an external cloud provider, which is most likely a public cloud. A public cloud is a cloud deployment model that is shared by multiple organizations and is hosted and managed by a third-party provider12. A public cloud offers the lowest cost, highest scalability, and widest availability, but also has less security, privacy, and customization34.
* Therefore, the best answer is A. Hybrid, which describes a cloud deployment model that combines a private cloud and a public cloud.

Out-of-band access is a remote access method that provides a separate, independent channel for accessing network devices and systems. Out-of-band access uses a dedicated network connection or a separate communication channel, such as a dial-up or cellular connection, to provide access to network devices and systems. This allows an administrator to access the management network even if the primary network connection is unavailable or impaired. Out-of-band access is a good solution for providing a redundant link to the management network in an incident response scenario because it can be used to access the network even if the primary connection is unavailable or impaired.
