2V0-41.23 Dumps with Practice Exam Questions Answers

The answer is A. SR is instantiated and automatically connected with DR.

SR stands for Service Router and DR stands for Distributed Router. They are components of the NSX Edge node that provide different functions1

The SR is responsible for providing stateful services such as NAT, firewall, load balancing, VPN, and DHCP. The DR is responsible for providing distributed routing and switching between logical segments and the physical network1

When a stateful service is enabled for the first time on a Tier-0 Gateway, the NSX Edge node automatically creates an SR instance and connects it with the existing DR instance. This allows the stateful service to be applied to the traffic that passes through the SR before reaching the DR2

According to the VMware NSX 4.x Professional Exam Guide, understanding the SR and DR components and their functions is one of the exam objectives3

To learn more about the SR and DR components and how they work on the NSX Edge node, you can refer to the following resources:

• VMware NSX Documentation: NSX Edge Components 1
• VMware NSX 4.x Professional: NSX Edge Architecture
• VMware NSX 4.x Professional: NSX Edge Routing

Federation is a feature of NSX that allows the administrator to manage multiple NSX instances with a single pane of glass view, create gateways and segments that span one or more locations, and configure and enforce firewall rules consistently across locations1. Federation provides centralized policy management for security and networking services for all locations and pushes it down to NSX Local Managers at the respective sites for enforcement1. Federation also enables disaster recovery and workload mobility scenarios by providing consistent network and security policies across different sites1. References: 1: NSX Federation - VMware Docs(https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-D5B6DC79-6733-44A7-8072-50221CF2122A.html)

According to the VMware NSX 4.x Professional documents and tutorials, a RouterLink port is a logical port that connects a Tier-1 gateway to a Tier-0 gateway. This port is automatically created when a Tier-1 gateway is associated with a Tier-0 gateway from the NSX UI or API. The RouterLink port enables routing between the two gateways and carries all the routing protocols and traffic. There is no need to manually create a logical switch or segment for this purpose1.

According to the VMware NSX Documentation, this is the NSX feature that can be leveraged to achieve consistent policy configuration and simplicity across sites:

• NSX Federation: This feature allows you to create and manage a global network infrastructure that spans across multiple sites using a single pane of glass. You can use this feature to synchronize policies, segments, gateways, firewalls, VPNs, load balancers, and other network services across sites.

According to the VMware NSX CLI Reference Guide, this CLI command shows the syslog messages on the NSX Manager node. You can use this command to view the system logs for troubleshooting or monitoring purposes.

The other options are either incorrect or not available for this task. get log-file auth.log is a CLI command that shows the authentication logs on the NSX Manager node, not the syslog messages. /var/log/syslog/syslog.log is not a CLI command, but a file path that may contain syslog messages on some Linux systems, but not on the NSX Manager node. show log manager follow is not a valid CLI command, as there is no show log command or manager option in the NSX CLI.

## NSX Cli command

get log-file

get log-file follow

# Below are commonly used log files, there are many more log files

get log-file [follow]

# use [follow] to continuing monitor

Example: get log-file syslog follow

get log-file syslog
