 When a FlexConnect AP changes to standalone mode, it means that the AP has lost or failed to establish CAPWAP connectivity with its Wireless LAN Controller (WLC). In this scenario, all controller-dependent activities stop working except for the Dynamic Frequency Selection (DFS). DFS is a mechanism that allows wireless LANs to use 5 GHz frequencies that are shared with radar systems. It is a part of the radio regulations applied to WLANs, and it is designed to avoid causing interference to radar systems.

In OSPF (Open Shortest Path First) configuration, the ‘network’ command is used to specify which interfaces will participate in OSPF, and to define the area assignment for those interfaces. The correct syntax for the ‘network’ command includes the network address followed by a wildcard mask, and then the area ID.

In this case, GigabitEthernet 0/1 has an IP address of 10.10.1.1 with a subnet mask of 255.255.255.0, which corresponds to a wildcard mask of 0.0.0.255 (the inverse of the subnet mask). Since we want this interface to participate in Area 0, as indicated by the exhibit showing it within Area 0’s boundary, option A is correct.

In Network Time Protocol (NTP), the stratum level represents the number of hops away from the authoritative time source. A stratum 1 server is directly connected to an authoritative time source, such as an atomic clock. Each subsequent stratum level represents an additional hop in the hierarchy. For example, a stratum 2 server gets its time from a stratum 1 server, a stratum 3 server gets its time from a stratum 2 server, and so on. The higher the stratum number, the further the device is from the authoritative time source, and potentially the less accurate the time. References: Explanation of Stratum Levels & NTP

 A type 2 hypervisor, also known as a hosted hypervisor, runs on top of a host operating system rather than directly on the hardware. This makes it ideal for client or end-user systems where ease of use and flexibility are more important than performance. Type 2 hypervisors are typically used for development, testing, or educational purposes where full virtualization of the underlying hardware is not necessary.
