Been studying hard for last 3 months and most of my daily life is spent troubleshooting so this exam felt the most natural. Watch Chris Bryants tshoot videos and also the CBT nugget course and labs. Also read How to master CCNP tshoot by Rene Molenar. Skimmed the OCG but this was a boring read this time around. Also read a lot of Narbiks new book called bridging the gap between ccnp and ccie. great read. gonna take a month off and then take ARCH.

Hi Shayan,
Believe it or not, what you are seeing is expected behavior from VRRP! If the authentication is not correct from a VRRP neighbor, then its packets get ignored. Each side will claim the other has incorrect authentication, so each VRRP router believes itself to be the master, and each will claim to own the IP address! The only upside to this is that assuming each side is using the same VRRP instance number, the MAC address will agree between them, so other computers on the network would have no idea this is going on. Additionally, should one of the
This section describes how to re-add a master node to a physical cluster. This scenario can happen if the node was accidentally or deliberately removed via configuration reset (such as acs reboot factory-reset) or vMedia re-install.
If you have a standby node in your cluster, simply convert the standby into a master node as described in Replacing Single Master Node with Standby Node and then add the old master node as a new standby node as described in Adding Standby Nodes.
If you need to completely replace (RMA) a master node due to hardware failure and do not have a standby node available, follow the procedure described in Replacing Single Physical Master Node without Standby Node instead.
This section describes how to recover from a master node failure in a VMware ESX or Linux KVM virtual Nexus Dashboard cluster. The procedure involves deploying a brand new Nexus Dashboard node using the same form factor as the node which you are replacing and joining it as a master node to the remaining cluster.
The following section describes how to recover from a single master node failure in a physical Nexus Dashboard cluster without a standby node. This procedure is for hardware issues that require it to be physically replaced. If the node is simply in a bad software state, you can use the acs reboot clean commands instead and re-add the same node to the cluster as described in Re-Adding Same Master Node to Physical Cluster.
You'll compare and master today's leading approaches to troubleshooting, including an efficient structured process for maximizing network uptime in the context of your own organization's policies and procedures. Coverage includes gathering information, capturing traffic, using event notifications, working with maintenance and trouble-shooting tools, and more.
Like HSRP, VRRP allows a group of routers to form a single virtual router. In an HSRP or VRRP group, one router is elected to handle all requests sent to the virtual IP address. With HSRP, this is the active router. An HSRP group has one active router, at least one standby router, and perhaps many listening routers. A VRRP group has one master router and one or more backup routers.
For the uninitiated, AWS stands for Amazon Web Services. And with everyone's increasing reliance on the cloud, it pays to have the skills to create, manage, and maintain cloud platforms. This bundle of nine courses will help prep you for the AWS Certified Database - Specialty (DBS-C01) and 2020 AWS Certified Solutions Architect - Associate (SAA-C02). You'll learn how to deploy architectures, familiarize yourself with various AWS storage options, create robust visualizations using AWS QuickSight, master all the aspects of databases, and more.
