Add the DNS entry for the new Cisco ISE node into the DNS server. This is because the fully qualified domain name (FQDN) of the new Cisco ISE node, for example, ise1.cisco.com, must be DNS-resolvable from the primary Administration ISE node. Otherwise, node registration will fail. The DNS server must contain the IP addresses and FQDNs of the ISE nodes that are part of the distributed deployment1.

The other options are incorrect because:

Changing the IP address of the new Cisco ISE node to the same network as the others is not necessary, as long as the nodes can communicate with each other over the network.

Making the new Cisco ISE node a secondary PAN before registering it with the primary is not possible, as the node must be registered first before changing its persona or role.

Opening port 8905 on the firewall between the Cisco ISE nodes is not required, as this port is used for communication between the primary and secondary Monitoring ISE nodes, not for node registration.

The API key is a secret token that is used to authenticate the client to the server. It is functionally equivalent to a username and password, and should be treated as such. The API key is passed as part of the HTTP header in the request, using the Authorization: Basic scheme. The API key is combined with the client ID and encoded in base64 format. For example, if the client ID is d16aff14860af496e848 and the API key is d01ed435-b00d-4a4d-a299-1806ac117e72, the HTTP header would look like this:

Authorization: Basic ZDE2YWZmMTQ4NjBhZjQ5NmU4NDg6ZDAxZWQ0MzUtYjAwZC00YTRkLWEyOTktMTgwNmFjMTE3ZTcy

The server then decodes the header and verifies the credentials. If the credentials are valid, the server grants access to the requested resource. If the credentials are invalid, the server returns an HTTP 401 Unauthorized error.

The API key performs the function of HTTP authentication, which is the process of verifying the identity of the client. HTTP authentication is different from HTTP authorization, which is the process of determining the permissions of the client. HTTP authorization is based on the scope of the API credential, which can be either read-only or read & write. The scope determines what actions the client can perform on the Cisco AMP for Endpoints data.

Importing requests is not a function of the API key, but rather a Python module that allows sending HTTP requests. Playing dent ID is not a meaningful term in this context. Therefore, the correct answer is C. References:

 The management port on Cisco FMC is used to establish a secure connection with the managed Cisco FTD devices. If the default management port (8305) conflicts with other communications on the network, it must be changed on both the Cisco FMC and the Cisco FTD devices. This cannot be done automatically by the Cisco FMC, as it would lose connectivity with the devices. Therefore, the administrator must manually change the management port on the Cisco FMC and all the managed Cisco FTD devices using the command line interface (CLI). The steps to change the management port are as follows:

Log into the CLI of the Cisco FMC and the Cisco FTD devices using a console connection or SSH.

Enter the configure network {ipv4 | ipv6} manual ip_address netmask data-interfaces command to change the management port on the Cisco FMC. For example, configure network ipv4 manual 10.10.10.10 255.255.255.0 data-interfaces changes the management port to 10.10.10.10/24.

Enter the configure network {ipv4 | ipv6} manual ip_address netmask gateway management-only command to change the management port on the Cisco FTD devices. For example, configure network ipv4 manual 10.10.10.11 255.255.255.0 10.10.10.10 management-only changes the management port to 10.10.10.11/24 and sets the gateway to the Cisco FMC’s management port.

Save the configuration and restart the Cisco FMC and the Cisco FTD devices.

Verify the connectivity between the Cisco FMC and the Cisco FTD devices using the show managers command on the Cisco FTD devices and the show devices command on the Cisco FMC.

In a Cisco Secure Workload implementation, telemetry data can be generated from IPFIX (Internet Protocol Flow Information Export) records using NetFlow connectors and Cisco Secure Workload itself. NetFlow provides insights into network traffic flow and volume, while Cisco Secure Workload uses this data for visibility, segmentation, and security analytics within the data center.

a Cisco FirePower sensor to Firepower Management Center is configure manager add . This command establishes a secure connection between the sensor and the FMC using a registration key. The  parameter can be either the IP address or the hostname of the FMC. The  parameter can be any alphanumeric string that matches the one configured on the FMC. This command is executed on the sensor’s CLI in the privileged EXEC mode12. References: 1: Implementing and Operating Cisco Security Core Technologies (SCOR) course, Module 2: Network Security, Lesson 2: Deploying Cisco Firepower Next-Generation Firewall, Topic: Registering the Cisco Firepower NGFW to the FMC2: Firepower Management Center Configuration Guide, Version 6.6 - Device Management Basics [Cisco Secure Firewall Management Center] - Cisco.

Explanation

Dynamic ARP inspection (DAI) is a security feature that validates ARP packets in a network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings. This capability protects the network from certain man-in-the-middle attacks. After enabling DAI, all ports become untrusted ports.

To block a website based on a custom list, the customer should add the websites to a blocked type destination list. A destination list is a custom list of domains or URLs that the customer wants to allow or block for their identities. The customer can create destination lists through the Policy Components > Destination Lists page, or within the policy wizard when creating or editing a policy. The custom URL destination block lists feature enables Umbrella to extend a domain level block list to encompass full and partial URLs. In turn, this allows the customer to block certain portions of a website based specifically on the full or partial URL. This feature requires the customer to enable the intelligent proxy and install a root certificate for SSL decryption. References:

Cisco standard NetFlow version 5 defines a flow as a unidirectional sequence of packets that all share seven values which define a unique key for the flow:

+ Ingress interface (SNMP ifIndex)

+ Source IP address

+ Destination IP address

+ IP protocol

+ Source port for UDP or TCP, 0 for other protocols

+ Destination port for UDP or TCP, type and code for ICMP, or 0 for other protocols

+ IP Type of Service

Note: A flow is a unidirectional series of packets between a given source and destination.

single methods of authentication can be compromised more easily than MFA. MFA, or multi-factor authentication, is a security process that requires users to provide two or more factors to verify their identity and access resources. MFA reduces the risk of unauthorized access by making it harder for attackers to compromise all the factors needed, especially if they are different in nature, such as something you know (password), something you have (token), and something you are (biometric).

To understand the concept of MFA and why it is important for authentication security, you can refer to the following sections of the source book:

Section 1.1.1: Describe the concepts of identity and access management

Section 1.1.1.1: Describe the concepts of identity principles

Section 1.1.1.2: Describe the concepts of authentication

Section 1.1.1.3: Describe the concepts of authorization

Section 1.1.1.4: Describe the concepts of accounting

Section 1.1.1.5: Describe the concepts of identity stores

Section 1.1.1.6: Describe the concepts of MFA

ZBFW stands for Zone-Based Firewall, which is a feature that allows unidirectional application of IOS firewall policies between groups of interfaces known as zones. Interfaces are assigned to zones, and firewall rules are applied to specific types of traffic moving in one direction between the zones. ZBFW enforces a secure inter-zone policy by default, meaning traffic cannot pass between security zones until an explicit policy allowing that traffic is defined. The zone itself is an abstraction of multiple interfaces with the same or similar security requirements that can be logically grouped together. ZBFW is CBAC’s replacement and offers intuitive policies for multiple-interface routers, increased granularity of firewall policy application, and a default deny-all policy that prohibits traffic between firewall security zones until an explicit policy is applied to allow desirable traffic. ZBFW is supported on IOS devices running 12.4(6)T or later, and ASR devices running 12.2(33) or later. References:

create an application control blocked applications list. This option allows you to specify a list of files that you want to prevent from running on the endpoints that have the AMP connector installed. The files are identified by their SHA-256 hashes, and you can upload them individually or in a batch. The files are not quarantined, but they are blocked from execution and reported as events in the AMP console1. This option is different from the simple custom detection list, which is used to detect and quarantine specific files that are considered malicious2. The advanced custom detection list is also used to detect and quarantine files, but it allows you to specify more criteria such as file size, file name, and file path3. The IP block and allow lists are used to control the network traffic to and from the endpoints, not the file execution4. References: 1: Configure Application Control on the AMP for Endpoints Portal 2: Configure a Simple Custom Detection List on the AMP for Endpoints Portal 3: [Configure an Advanced Custom Detection List on the AMP for Endpoints Portal] 4: [Configure IP Block and Allow Lists on the AMP for Endpoints Portal]

A cloud access security broker (CASB) is a security solution that helps protect cloud-hosted services and applications from cyberattacks and data breaches. A CASB acts as an intermediary between cloud users and cloud providers, and enforces the organization’s security policies and compliance requirements. A CASB integrates with other cloud solutions via APIs and monitors the cloud activity and data across multiple platforms and devices. A CASB can also create incidents based on events from the cloud solution, such as unauthorized access, data leakage, malware infection, or policy violation. A CASB can then alert the administrators, block the malicious actions, or remediate the issues. A CASB provides visibility, control, and protection for the organization’s cloud environment12.
