This is because Fast Transition (FT) is a feature that allows 802.11r-capable clients to roam faster between access points by reducing the authentication and key exchange time. FT can be configured in two modes: adaptive and over-the-DS. Adaptive mode is recommended for mixed environments where both 802.11r-capable and non-capable clients are present, as it allows the access point to negotiate the FT mode with the client. Over-the-DS mode is only suitable for environments where all clients are 802.11r-capable, as it requires the access point to communicate with the previous access point over the distribution system. FT + PSK is a security option that enables FT with pre-shared key (PSK) authentication, which is a simple and common method of securing wireless networks. WPA2-AES is an encryption standard that provides strong security and privacy for wireless networks.

This is because the CoPP configuration shown in the exhibit applies a service policy to the control plane of the router, which is responsible for processing the routing protocols, management protocols, and other control traffic. The service policy uses a class map that matches the access list 100, which permits the traffic with the source IP address 10.1.1.1. The service policy also uses a policy map that sets the committed information rate (CIR) for the matched traffic to 64 kbps, which means that the traffic is guaranteed to have a minimum bandwidth of 64 kbps. The policy map also sets the exceed action to drop, which means that any traffic that exceeds the CIR will be dropped. Therefore, the traffic that matches entry 10 of ACL 100 is always allowed with a limited CIR, and any excess traffic is dropped.

This is because a virtual switch is a software-based switch that operates at the data link layer of the OSI model and provides connectivity between virtual machines that are running on the same physical host or different hosts. A virtual switch can also connect virtual machines to external networks, such as the Internet or a local area network, by using physical network adapters on the host. A virtual switch can perform the same functions as a physical switch, such as learning MAC addresses, forwarding frames, and applying VLANs.

This is because Cisco FlexConnect is a feature that allows wireless access points to operate in standalone mode when they lose connectivity to the wireless LAN controller. Cisco FlexConnect has different states depending on the status of the authentication and switching functions. Authentication-Down means that the access point cannot authenticate new users with the central server, such as a RADIUS server. Switch-Local means that the access point can switch the traffic locally without sending it to the wireless LAN controller. Therefore, Authentication-Down / Switch-Local is the state that rejects new users but allows existing users to function normally. The source of this answer is the Cisco ENCOR v1.1 course, module 7, lesson 7.3: Implementing FlexConnect.

Option A is the properly formatted JSON script. JSON (JavaScript Object Notation) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa).The JSON syntax rules are as follows12:

Data is in name/value pairs, separated by commas. A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value:'name': 'value'.

Curly braces hold objects. An object can contain multiple name/value pairs:{'name': 'value', 'name': 'value', ...}.

Square brackets hold arrays. An array can contain multiple values, separated by commas:['value', 'value', ...].

Values can be strings (in double quotes), numbers, booleans (true or false), null, objects, or arrays.

Option A follows these rules and is a valid JSON script. It defines an object with four name/value pairs:'name','age','hobbies', and'address'. The value of'name'is a string, the value of'age'is a number, the value of'hobbies'is an array of strings, and the value of'address'is another object with two name/value pairs:'city'and'country'. The object is enclosed in curly braces and the name/value pairs are separated by commas.

Option B is not a valid JSON script because it uses single quotes instead of double quotes for the field names and string values.JSON requires double quotes for strings12.

Option C is not a valid JSON script because it does not use commas to separate the name/value pairs.JSON requires commas to separate the data elements within an object or an array12.

Option D is not a valid JSON script because it uses a semicolon instead of a colon to separate the field name and the value.JSON requires a colon to separate the name and the value in a name/value pair12.Reference:1:JSON Introduction,2:JSON Syntax

A type 1 hypervisor, also known as a bare-metal or native hypervisor, runs directly on the physical server and its underlying hardware. It does not depend on a previously installed operating system, but rather includes its own operating system that is designed to run virtual machines. A type 1 hypervisor provides excellent performance and stability, as it has direct access to the hardware resources and can allocate them to the virtual machines. A type 1 hypervisor is typically used in enterprise environments, where multiple virtual machines run on a single server.
