Exam N10-008 topic 1 question 383 discussion

The protocols that can be used to change device configurations via encrypted and authenticated sessions are: A. SNMPv3 B. SSH SNMPv3 (Simple Network Management Protocol version 3) is a protocol that provides secure access to network devices by encrypting and authenticating SNMP messages. It is used to manage and monitor network devices and can be used to change device configurations. SSH (Secure Shell) is a protocol that provides secure remote access to network devices by encrypting and authenticating sessions between devices. It is commonly used to access and manage network devices, such as routers and switches, and can be used to change device configurations.

A, B. SSH can pass secure instructions SNMPv3 also has this ability during network monitoring

A, B totes

Not D because IPsec is considered a suite of protocols, not just one, plus not necessarily used for network management, although used for network security.

it is A and B

IPsec encapsulates the IP packets giving them an extra more secure jacket with autentication capabillities, and extra fuller pockets ^^ getting it over the magic 1500 border. making the datasize more important. Ofcourse it encrypts the data and it can be used for authetication, but other then adding some routes and interfaces it can't change configuration of a device.

the question states "can be used to change device configurations" with an SNMP manager (like ZABBIX ect.) it is possible to use scripts to change settings on a device. SSH well its SSH'.

A. SNMPv3 (Simple Network Management Protocol version 3) provides secure access to network devices for monitoring and managing device configurations. SNMPv3 uses encryption and authentication to protect data during transmission and to prevent unauthorized access. B. SSH (Secure Shell) is a network protocol used to provide secure encrypted access to remote devices. It can be used to securely manage network devices, including changing device configurations, by providing an encrypted and authenticated session.

Like was mentioned by others, SSH and IPSec make sense because they allow changing configurations. IPsec is a group of protocols that are used together to set up encrypted connections between devices. It helps keep data sent over public networks secure. IPsec is often used to set up VPNs, and it works by encrypting IP packets, along with authenticating the source where the packets come from.

B and D

SNMPv3 - Authenticated & encrypted by prof messer youtube video (https://www.youtube.com/watch?v=p0ZIQ2HhkH8&list=PLG49S3nxzAnlCJiCrOYuRYb6cne864a7G&index=55) IPSEC - Authenticated & encrypted SSH - Only encrypted

SNMPv3 provides encryption yes, but does not let you change device configurations.

the correct are B + D

SNMPv3 and SSH

Definitely A and B SNMPv3 allows you to configure Network devices with an encrypted channel and SSH is itself a secure channel to make remote connections to network devices so you can configure them.

SNMPv3 provides secure access to network devices and SSH provides a secure way to access and manage devices remotely via a command-line interface. IPSec is a security protocol that can be used to encrypt and authenticate network traffic, but it is typically not used to change device configurations.

I believe the answers are A and B https://www.oreilly.com/library/view/cisco-ios-cookbook/0596527225/ch17s09.html
