The Application Visibility and Control (AVC) engine lets you create policies to control application activity on the network without having to fully understand the underlying technology of each application. You can configure application control settings in Access Policy groups. You can block or allow applications individually or according to application type. You can also apply controls to particular application types.

Network telemetry is a technology that allows network devices to push data to a collector in real time, rather than waiting for the collector to pull data from them. This improves the efficiency and accuracy of data collection, and enables the monitoring of a large number of network devices. SNMP, on the other hand, is a protocol that uses a pull model, where the collector requests data from the devices periodically. This can cause delays, gaps, and overhead in data collection, and limit the scalability of network monitoring. Therefore, network telemetry has an advantage over SNMP pulls in terms of scalability. References:

The command show authen sess int gi0/1 displays the authentication session information for the interface gi0/1, such as the MAC address, the authentication method, the authentication state, the session timeout, and the VLAN assignment. This command is useful for verifying the status of an 802.1X connection on a specific interface. The other commands are not related to 802.1X authentication. The command show authorization status displays the authorization status for the current user. The command show connection status gi0/1 is not a valid Cisco command. The command show ver gi0/1 displays the version information for the interface gi0/1. References: 802.1X Authentication Commands, Configuring IEEE 802.1x Port-Based Authentication, What Cisco command shows you the status of an 802.1X connection on interface gi0/1?

Cisco Umbrella Investigate provides a comprehensive view of Internet domains, IP addresses, and autonomous systems, offering a wealth of information about the infrastructure of the internet. It helps security analysts and threat investigators to pinpoint current and emerging threats by providing access to data from Cisco's global network, thereby enabling the identification of attackers and malicious infrastructures.

WannaCry ransomware is a type of malware that encrypts the files on the infected devices and demands a ransom for their decryption. It exploits a vulnerability in the Windows SMB protocol that allows remote code execution. To prevent WannaCry ransomware from spreading to all clients, IT should take the following precautions:

Ensure that noncompliant endpoints are segmented off to contain any potential damage. This means that any device that is not patched, managed, or compliant with the security policies should be isolated from the rest of the network and given limited access to resources. This can be done using Cisco Identity Services Engine (ISE) and Cisco TrustSec, which can enforce dynamic segmentation based on the device’s identity, posture, and context. This way, IT can prevent the ransomware from infecting other devices and reduce the impact of the attack12

Perform a posture check to allow only network access to those Windows devices that are already patched. This means that IT should verify that the devices have installed the latest security updates from Microsoft that fix the SMB vulnerability. This can be done using Cisco AnyConnect Secure Mobility Client, which offers a VPN Posture/HostScan Module and an ISE Posture Module. Both modules can assess the endpoint’s compliance for things like operating system, patches, antivirus, antispyware, and firewall software. If the device is not patched, it can be denied access to the network or redirected to a remediation portal13

ESA stands for Email Security Appliance, which is a Cisco product that provides comprehensive email security solutions. ESA can be deployed in different modes, such as gateway, hybrid, or cloud, depending on the customer’s needs and preferences. One of the key components of ESA configuration is the listener, which is a service that listens for incoming SMTP connections on a specific port and interface. A listener can be configured to handle inbound or outbound email, or both, depending on the mail flow policies and sender groups that are applied to it.

One way to segregate inbound and outbound email on ESA is to use a pair of logical listeners on a single physical interface with two unique logical IPv4 addresses and one IPv6 address. This method allows the ESA to have two separate listeners for inbound and outbound email, each with its own IP address and mail flow policies, while using the same physical interface and port. This can simplify the network configuration and reduce the hardware requirements for ESA deployment. The IPv6 address can be used to support dual-stack IPv4 and IPv6 environments, or to provide redundancy in case of IPv4 address exhaustion.

The other options are incorrect because:

A is false, as one listener on a single physical interface cannot segregate inbound and outbound email, unless it uses different sender groups and mail flow policies for different hosts, which is not a recommended practice.

C is false, as pair of logical IPv4 listeners and a pair of IPv6 listeners on two physically separate interfaces is an unnecessary and complex configuration that does not provide any additional benefits over option B.

D is false, as one listener on one logical IPv4 address on a single logical interface cannot segregate inbound and outbound email, unless it uses different sender groups and mail flow policies for different hosts, which is not a recommended practice.

Cisco ESA uses a multilayer approach to fight viruses and malware. The first layer of defense consists of outbreak filters, which the appliance downloads from Cisco SenderBase. Outbreak filters use global threat intelligence and behavioral analysis to identify and block emerging threats before they reach the network. The second layer of defense consists of antivirus engines, which scan the message body and attachments for known viruses and malware. Cisco ESA supports multiple antivirus engines, such as Sophos, McAfee, and Cisco AMP. The Sophos engine is one of the default engines that Cisco ESA uses, along with McAfee. The Sophos engine provides fast and accurate detection of viruses and malware, and updates its signatures frequently. The other options are not features that are used to configure Cisco ESA with a multilayer approach to fight viruses and malware. A white list is a list of trusted senders or recipients that are exempt from spam or virus filtering. RAT is the Recipient Access Table, which is used to determine whether the appliance accepts or rejects messages to a recipient address. DLP is Data Loss Prevention, which is used to prevent sensitive or confidential data from leaving the network. References :=

In transparent mode, the WSA can handle both explicit and transparent HTTP requests, depending on how the client browser is configured. The WSA must pretend to be the origin content server for transparent requests, since the client is unaware of the existence of a proxy1. WCCP v2 is a protocol that allows a WCCP-enabled device (such as a router or a switch) to redirect traffic to the WSA based on certain criteria, such as destination port 802. This way, the client does not need to configure a proxy or a PAC file in the browser. The other options are false because they are either required for explicit mode or not supported by the WSA. References :=

Cisco Firepower NGFW Virtual (NGFWv) is the virtualized version of Cisco’s Firepower next generation firewall.

The Cisco NGFW virtual appliance is available in the AWS and Azure marketplaces. In AWS, it can be

deployed in routed and passive modes. Passive mode design requires ERSPAN, the Encapsulated Remote Switched Port Analyzer, which is currently not available in Azure.

In passive mode, NGFWv inspects packets like an Intrusion Detection System (IDS) appliance, but no action can be taken on the packet.

In routed mode NGFWv acts as a next hop for workloads. It can inspect packets and also take action on the packet based on rule and policy definitions.

Workloaded security models are ways of protecting applications, services, and capabilities that run on a cloud resource. Virtual machines, databases, containers, and applications are all considered cloud workloads. There are different types of cloud deployment models, such as public, private, hybrid, and multicloud. Depending on the deployment model, the cloud workload security can vary in terms of responsibility, visibility, and control.

Infrastructure as a service (IaaS) is a cloud deployment model where the cloud provider offers the basic computing infrastructure, such as servers, storage, and networking, as a service. The customer is responsible for installing, configuring, and managing the operating systems, applications, and security of the workloads that run on the cloud infrastructure. IaaS provides the customer with more flexibility and control over the workload security, but also more complexity and overhead.

On-premises is a deployment model where the customer owns and operates the entire IT infrastructure, including the hardware, software, and security. The customer has full responsibility and control over the workload security, but also the highest cost and maintenance. On-premises deployment can offer more security and compliance than cloud deployment, depending on the customer’s security posture and practices.
