The correct command to log all events to a destination collector is flow-export event-type all destination 209.165.201.10. This command configures a flow-export action that sends all NSEL events to the specified IP address. NSEL events include flow-create, flow-teardown, flow-denied, and flow-update events. The command must be entered in the policy-map class configuration mode, after defining a policy-map and a class-map that match the traffic and event type. The other commands are incorrect because they either specify the wrong event type (flow-update instead of all) or the wrong destination IP address (209.165.201 instead of 209.165.201.10). References :=

Explanation

All IKE policies on the device are sent to the remote peer regardless of what is in the selected policy section.

The first IKE Policy matched by the remote peer will be selected for the VPN connection. Choose which policy is sent first using the priority field. Priority 1 will be sent first.

to configure GigabitEthernet0/1 as promiscuous port, GigabitEthernet0/2 as isolated port and GigabitEthernet0/3 and GrgabitEthernet0/4 as community ports. This way, the default gateway can communicate with all servers, the isolated port can only communicate with the promiscuous port, and the community ports can communicate with each other and the promiscuous port. This prevents the file server from communicating with the DNS servers, as required by the question.

Posture is a service in Cisco ISE that allows you to check the compliance, also known as posture, of endpoints, before allowing them to connect to your network. A posture agent, such as the AnyConnect ISE Posture Agent or Network Admission Control (NAC) Agent, runs on the endpoint and collects information about the endpoint’s security posture, such as antivirus, antispyware, firewall, and patch status. The posture agent then communicates with the ISE server, which evaluates the posture information against the posture policy and determines the compliance state of the endpoint. Based on the compliance state, the ISE server can grant or deny network access to the endpoint, or apply remediation actions to bring the endpoint into compliance. Posture service is part of the ISE solution for network access control (NAC), which aims to secure the network from unauthorized or compromised endpoints. References:

Cisco ISE is the security solution that is used for posture assessment of the endpoints in a BYOD solution. Posture assessment allows Cisco ISE to inspect the security health of the endpoints, such as their operating system, software applications, network settings, and security software. Cisco ISE can then enforce posture policies based on the compliance status of the endpoints and grant or deny them access to the network resources. Cisco ISE supports different types of posture agents, such as AnyConnect, AnyConnect Stealth, and Temporal Agent, to monitor and remediate the endpoints. Cisco ISE also supports agentless posture for devices that cannot run an agent, such as printers, cameras, and IoT devices. Cisco ISE integrates with various third-party vendors to provide posture assessment for different endpoint platforms, such as Windows, Mac, Linux, Android, and iOS. References :=

The dot1x pae authenticator command enables 802.1x authentication on the port and configures the port as an authenticator. This command is required for the port to initiate the authentication process with the connected client. Without this command, the port will not send EAPOL packets to the client and will not receive the client credentials. Therefore, the client will not be authenticated and will remain in the unauthorized state. The other options are not mandatory for 802.1x authentication, although they can be used to modify the default behavior of the port. For example, authentication open allows the port to grant access to the client before authentication, dot1x reauthentication enables periodic reauthentication of the client, and cisp enable enables Cisco Identity Services Protocol (CISP) on the port. References: Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0, Module 5: Secure Network Access, Lesson 5.1: Implementing 802.1X Authentication, Topic 5.1.2: Configuring 802.1X Authentication, Page 5-9.

Southbound APIs are used to communicate between the SDN Controller and the switches and routers of the network. They can be open-source or proprietary. They facilitate control over the network and enable the SDN Controller to dynamically make changes according to real-time demands and needs. OpenFlow and OpFlex are two examples of southbound APIs. OpenFlow, which was developed by the Open Networking Foundation (ONF), is the first and probably most well-known southbound interface. OpenFlow defines the way the SDN Controller should interact with the forwarding plane to make adjustments to the network, so it can better adapt to changing business requirements. With OpenFlow, entries can be added and removed to the internal flow-table of switches and routers to make the network more responsive to real-time traffic demands. OpFlex, which was proposed by Cisco, is another southbound interface that uses a declarative model to communicate policies and state between the controller and the network devices. OpFlex allows the network devices to retain some intelligence and autonomy, while still being managed by the controller. OpFlex is designed to be flexible and extensible, and can support different types of network devices and services. Services running over the network, external application APIs, and applications running over the network are not southbound APIs, as they do not directly communicate between the controller and the network devices. Therefore, the correct answer is B and E. References :=

The zero-trust model is a modern security strategy that assumes breach and verifies each request as though it originates from an open network. The main concept behind the zero-trust model is “never trust, always verify”, which means that users and devices should not be trusted by default, even if they are connected to a permissioned network such as a corporate LAN and even if they were previously verified12

One of the principles of the zero-trust model is to verify explicitly, which means to always authenticate and authorize based on all available data points, including user identity, location, device health, service or workload, data classification, and anomalies13 To achieve this, the zero-trust model recommends using multifactor authentication (MFA), which is a method of verifying a user’s identity by requiring two or more pieces of evidence, such as something the user knows (e.g., password, PIN), something the user has (e.g., token, smart card), or something the user is (e.g., fingerprint, face scan). MFA provides a higher level of security than using only a single factor, such as a password, which can be easily compromised or guessed. MFA also reduces the risk of unauthorized access to corporate applications and resources, which may contain sensitive or confidential information.

Therefore, the recommendation in a zero-trust model before granting access to corporate applications and resources is to use multifactor authentication, as it ensures that only verified and authorized users and devices can access the data they need, and nothing more13

Cisco AMP for Endpoints is a next generation endpoint security solution that provides prevention, detection, and response capabilities. One of its functions is to automate threat responses of an infected host by isolating it from the network, blocking malicious files, and removing them from all endpoints. This reduces the time and effort required to contain and remediate a threat, and prevents further damage or data loss. According to the source book, Cisco AMP for Endpoints can perform the following automated responses1:

Endpoint Isolation: This feature allows you to isolate an endpoint from the network if it is compromised or infected. This prevents the endpoint from communicating with other devices or servers, and stops the spread of malware or exfiltration of data. You can isolate an endpoint manually from the console, or automatically based on a policy or a detection. You can also restore the network connectivity of an isolated endpoint when it is safe to do so.

File Blocking: This feature allows you to block a file from executing on any endpoint if it is deemed malicious or suspicious. You can block a file manually from the console, or automatically based on a policy or a detection. You can also unblock a file if it is a false positive or no longer a threat.

File Removal: This feature allows you to remove a file from any endpoint if it is malicious or unwanted. You can remove a file manually from the console, or automatically based on a policy or a detection. You can also restore a file from quarantine if it is a false positive or needed for analysis.
