One of the primary benefits of test-driven development (TDD) is increased code quality. By writing tests before coding and continuously testing during development, developers ensure that the code meets the specified requirements and behaves as expected. This approach leads to more reliable, maintainable, and bug-free code.

The exhibit demonstrates an example of cross-site scripting (XSS) . This type of attack i n volves injecting malicious scripts into web pages viewed by other users. In this example, the script < script > alert( ' I want to pass the DevNet Associate Exam. ' ); < /script > is embedded into a URL, and when accessed, it displays an alert message in the web browser.

Cross-Site Scripting (XSS) : A security vulnerability typically found in web applic a tions that allows attackers to inject malicious scripts into content from otherwise trusted we b sites.

DNS (Domain Name System) is the service that provides a directory lookup for IP addresses and host names. DNS translates human-readable domain names (like www.example.com ) into IP addresses that computers use to identify each other on the network.

DNS: Converts domain names into IP addresses and vice versa.

DHCP: Dynamically assigns IP addresses to devices on a network.

SNMP: Used for network management and monitoring.

NAT: Translates private IP addresses to a public IP address for accessing the internet.

In REST architecture, the stateless constraint indicates that no client context should be stored on the server between requests. Each request from the client to the server must contain all the information needed to understand and process the request.

Stateless : Ensures that each request is independent and contains all necessary info r mation.

Uniform interface : Defines a standard way of interacting with resources.

Cacheable : Responses must define whether they are cacheable to improve perfo r mance.

Client-server : Separates the client and server roles.

Generating log bundles is a resource-intensive task that can cause high CPU utilization on the Cisco DNA Center. When the CPU spikes, it can affect the performance of other critical tasks, such as forwarding voice IP packets, leading to delays and poor voice quality. This is especially noticeable during business hours when network utilization is high, and voice traffic is sensitive to latency and jitter. More details can be found in Cisco DNA Center documentation on Managing Logs and System Performance.

To restrict access to the management interface of devices using SSH and HTTPS, the correct ports need to be included in the ACLs.

Port 22 : Used by SSH (Secure Shell) for secure remote login and command execution.

Port 443 : Used by HTTPS (Hypertext Transfer Protocol Secure) for secure web traffic.

Options A and D are correct as they are the standard ports for SSH and HTTPS.

A VLAN (Virtual Local Area Network) allows devices on one or more LANs to be grouped together as if they were on the same physical network, even if they are not.

Logical Segmentation : VLANs provide logical segmentation of networks, enabling devices to communicate as if they are on the same physical network.

Isolation and Flexibility : They offer isolation and flexibility in network design, i m proving security and reducing broadcast domains.

Option B is correct as VLANs create logical groupings of devices that communicate as if they are on the same physical LAN.

The error message in the cURL response indicates that the request requires a valid access token set in the Authorization request header. This error is common when the authorization header is either missing or the token provided is incorrect or expired.

To resolve this issue, ensure the correct Bearer token is included in the Authorization header, formatted as follows:

-H " Authorization: Bearer YOUR_ACCESS_TOKEN "

Version control software offers numerous benefits to development teams. Key advantages i n clude:

Comparisons between revisions of source code files : Version control allows develo p ers to compare different versions of source code files, track changes, and identify what modif i cations were made and by whom. This is essential for debugging and maintaining code quality.

Access to current code and history for new team members : New team members can quickly get up to speed by accessing the current version of the code and the entire history of changes. This transparency facilitates onboarding and improves collaboration among team members.
