350-701 Exam Dumps - Cisco CCNP Security Questions and Answers

Multiple context mode allows you to partition a single ASA into multiple virtual firewalls, each with its own security policy, interfaces, and management IP address. This mode is useful for providing security services to different customers or tenants on a shared appliance, while maintaining separation of management and configuration. Each context acts as an independent device and can be in either routed or transparent mode. You can also assign different administrators to each context and limit their access to specific commands and features. Multiple context mode is supported in Cisco ACI with the ASA device package version 1.2 or later. References:

The exhibit presents several mutually reinforcing indicators: a Threat Score of 92/100, a High Risk classification, poor reputation, malicious classification, DNS tunneling, malware hosting, and domain-generation-algorithm activity. Option D is therefore the supported conclusion. The domain’s age of four days is a warning signal, but the display does not say that age alone caused the block, so option A overstates one factor. Option B conflicts with the four-day age and incorrectly describes the domain as legacy. Option C reverses the meaning of the Security Score display: 25/100 is explicitly labeled Critical, not safe. Cisco states that Investigate risk scoring combines domain-name characteristics and query patterns, and that analysts should use the contributing security features for triage. Cisco Secure Access Investigate API supports this evidence-based interpretation.

The IOS AAA login method-list syntax is aaa authentication login {default | list-name} method-list. Option C creates the default login list, selects the named TACACS+ server group first, and specifies the local user database as the next method when the group is unavailable. Cisco’s AAA authentication guidance confirms that aaa authentication login default group tacacs+ local prefers TACACS+ and uses local authentication when the servers do not respond. Option A reverses the desired priority and uses invalid method-list construction. Option B omits the required default or named-list position before the methods. Option D applies neither the correct login method-list syntax nor the SSH access requirement. The fallback occurs for a server error or timeout, not for an explicit TACACS+ rejection. Therefore, C is the correct command.

Explanation

Cisco ISE can determine the type of device or endpoint connecting to the network by performing “profiling.”

Profiling is done by using DHCP, SNMP, Span, NetFlow, HTTP, RADIUS, DNS, or NMAP scans to collect as

much metadata as possible to learn the device fingerprint.

NMAP (“Network Mapper”) is a popular network scanner which provides a lot of features. One of them is the

OUI (Organizationally Unique Identifier) information. OUI is the first 24 bit or 6 hexadecimal value of the MAC

address.

Note: DHCP probe cannot collect OUIs of endpoints. NMAP scan probe can collect these endpoint attributes:

+ EndPointPolicy

+ LastNmapScanCount

+ NmapScanCount

+ OUI

+ Operating-system

 The API key is used for HTTP authentication when working with APIs, including https://api.amp.cisco.com/v1/computers. It ensures that the user or system making the API request is authenticated and authorized to access the resources requested. The image you sent shows a Python code snippet that imports the requests module, assigns a client ID and an API key to variables, and uses them to make an API call. The API key is passed as a header parameter in the requests.get() function, which is a common way of implementing HTTP authentication. The other options are not correct because they do not describe the role of the API key. The client ID is a different parameter that identifies the user or system making the request, but it does not authenticate them. HTTP authorization is a process of granting or denying access to resources based on the user’s identity and permissions, but it is not the same as authentication. Importing requests is a Python statement that loads the requests module, which is a library for making HTTP requests, but it has nothing to do with the API key. References :=

The main difference between an on-premise solution and a cloud-based solution is the distribution of responsibilities between the customer and the provider. With an on-premise solution, the customer has full control over the installation, configuration, maintenance, and security of the product, but also bears the costs and risks associated with it. With a cloud-based solution, the provider takes care of most of these aspects, while the customer pays a subscription fee and accesses the product over the internet. Therefore, when choosing between the two options, the customer must consider factors such as cost, scalability, performance, availability, security, compliance, and customization. For example, an on-premise solution may be preferred if the customer has strict security or regulatory requirements, or needs a high level of customization. A cloud-based solution may be preferred if the customer wants to reduce capital expenditure, or needs a flexible and scalable solution that can adapt to changing demands. References :=

 IOS zone-based firewalls (ZBFW) are a feature that provides stateful firewall policies between groups of interfaces known as zones. A zone is a logical grouping of one or more interfaces that have similar security requirements. A zone can be applied to physical interfaces, subinterfaces, port channels, VLAN interfaces, or tunnel interfaces. However, an interface can be assigned only to one zone, and it cannot be shared between zones. This is because the ZBFW policy is applied between zones, not interfaces, and it controls the bidirectional traffic flow between them. Therefore, an interface can belong to only one zone at a time, and it must be removed from one zone before it can be added to another zone. This ensures that the firewall policy is consistent and unambiguous for each interface.

AES (Advanced Encryption Standard) is a symmetric encryption algorithm that uses the same key to encrypt and decrypt data. It turns plain text into a code that only the intended recipient can read. AES has different key sizes, such as 128, 192, and 256 bits. The larger the key size, the more secure and complex the encryption is. AES 256 is the most secure encryption algorithm for VPN communications, as it uses a 256-bit key that would take an enormous amount of time and computing power to crack. AES 256 is widely used by VPN providers, as it offers a high level of security and performance for VPN tunnels. AES 256 is also recommended by the U.S. government for protecting classified information. References :=

Endpoint-based security is the solution for performing signature-based application control, which is a method of identifying and blocking malicious applications based on their signatures or hashes. Signature-based application control is one of the features of endpoint security solutions, such as Cisco AMP for Endpoints1, that protect endpoints from known and unknown threats. Endpoint security solutions can also perform other functions, such as behavioral analysis, sandboxing, machine learning, and threat hunting, to provide comprehensive protection, detection, and response on the endpoint2. The other options are not scenarios where endpoint-based security is the solution. Inspecting encrypted traffic requires a network-based security solution, such as Cisco SSL Appliance3, that can decrypt and inspect the traffic for malicious content. Device profiling and authorization requires a network access control solution, such as Cisco Identity Services Engine4, that can identify and authenticate devices and users and enforce policies based on their roles and contexts. Inspecting a password-protected archive requires a file analysis solution, such as Cisco Threat Grid5, that can extract and analyze the contents of the archive for malware and indicators of compromise. References :=

An active/active FlexVPN configuration allows for multiple routers or VRFs to act as hubs for different VPN groups, providing load balancing and redundancy1. This is useful when the VPN deployment has a large number of spokes or different security policies for different groups of spokes. DMVPN, on the other hand, only supports a single hub or a pair of hubs in active/standby mode for each VPN group2. This limits the scalability and flexibility of DMVPN deployments. Therefore, an engineer would opt for an active/active FlexVPN configuration as opposed to DMVPN when multiple routers or VRFs are required. References :=

NetFlow is a baseline form of telemetry that is recommended for network infrastructure devices. NetFlow is a technology that collects and exports information about IP traffic flows on enabled interfaces. NetFlow can provide valuable insight into the network performance, utilization, behavior, and security. NetFlow can help identify anomalies, such as DDoS attacks, malware, or misconfigurations, by comparing the current traffic patterns with the normal or baseline ones. NetFlow can also help with capacity planning, troubleshooting, and forensic analysis. NetFlow is supported on various Cisco platforms, such as routers, switches, firewalls, and IPS sensors. NetFlow can export data to different collectors and analyzers, such as Cisco Security Monitoring, Analysis and Response System (CS-MARS), Cisco Traffic Anomaly Detectors and Cisco Guard DDoS Mitigation Appliances, Cisco Network Analysis Module (NAM), and other third-party tools. References:

Explanation

Cisco DNA Center has four general sections aligned to IT workflows:

Design: Design your network for consistent configurations by device and by site. Physical maps and logical topologies help provide quick visual reference. The direct import feature brings in existing maps, images, and topologies directly from Cisco Prime Infrastructure and the Cisco Application Policy Infrastructure Controller

Enterprise Module (APIC-EM), making upgrades easy and quick. Device configurations by site can be

consolidated in a “golden image” that can be used to automatically provision new network devices. These new devices can either be pre-staged by associating the device details and mapping to a site. Or they can be claimed upon connection and mapped to the site.

Policy: Translate business intent into network policies and apply those policies, such as access control, traffic routing, and quality of service, consistently over the entire wired and wireless infrastructure. Policy-based access control and network segmentation is a critical function of the Cisco Software-Defined Access (SDAccess) solution built from Cisco DNA Center and Cisco Identity Services Engine (ISE). Cisco AI Network Analytics and Cisco Group-Based Policy Analytics running in the Cisco DNA Center identify endpoints, group similar endpoints, and determine group communication behavior. Cisco DNA Center then facilitates creating policies that determine the form of communication allowed between and within members of each group. ISE then activates the underlying infrastructure and segments the network creating a virtual overlay to follow these

policies consistently. Such segmenting implements zero-trust security in the workplace, reduces risk, contains

threats, and helps verify regulatory compliance by giving endpoints just the right level of access they need.

Provision: Once you have created policies in Cisco DNA Center, provisioning is a simple drag-and-drop task.

The profiles (called scalable group tags or “SGTs”) in the Cisco DNA Center inventory list are assigned a policy, and this policy will always follow the identity. The process is completely automated and zero-touch. New devices added to the network are assigned to an SGT based on identity—greatly facilitating remote office setups.

Assurance: Cisco DNA Assurance, using AI/ML, enables every point on the network to become a sensor, sending continuous streaming telemetry on application performance and user connectivity in real time. The clean and simple dashboard shows detailed network health and flags issues. Then, guided remediation

automates resolution to keep your network performing at its optimal with less mundane troubleshooting work.

The outcome is a consistent experience and proactive optimization of your network, with less time spent on troubleshooting tasks.
