Our Community Study Guide is looking more and more finished. It will be a good tool to help you pass a VMware VCP-DCV certification exam. Today is a day where we go for another topic that is present on the latest VMware Blueprint, that covers all chapters of the VCP-DCV certification exam based on VMware vSphere 8.x. The topic is VCP-DCV on vSphere 8.x Objective 4.19.2 – Configure ESXi firewall.
A short chapter that is easy to check and learn. If you have a lab, you can just test it. If you don't, then read on….
The study guide page VCP8-DCV with all those individual chapters helps you with learning towards VMware certification exam (2V0-21. 23) and to became VCP-DCV on vSphere 8.x. Check the Official VMware VCP-DCV 2023 exam guide (blueprint) here. Also please check the certification requirements (depends on if you hold already a VCP etc..)
Starting with vSphere 7.0, vSphere Lifecycle Manager introduces the option of using vSphere Lifecycle Manager images as an alternative way to manage the lifecycle of the hosts and clusters in your environment. You can also use vSphere Lifecycle Manager to upgrade the virtual machine hardware and VMware Tools versions of the virtual machines in your environment.
VMware has become a transition from baseline based updates to Image based updates. VMware Lifecycle Manager (VLM) enables you to have all hosts in a cluster inherit the same image, thus removing variability between hosts. Using a single image means faster upgrades, improved reliability and easier overall maintenance.
You can use vSphere client and vLCM to update your environment, your hosts, your cluster etc. There are a couple of operations you need to be aware of:
Compliance Check – An operation of scanning ESXi hosts to determine their level of compliance with a baseline attached to the cluster or with the image that the cluster uses. The compliance check does not alter the object.
Remediation Pre-Check – An operation that you perform before remediation to ensure that the health of a cluster is good and that no issues occur during the remediation process.
Remediation – This is an operation that does the actual software updates to the ESXi hosts in a cluster. During remediation, you install software on the hosts. Remediation makes a non-compliant host compliant with the baselines attached to the cluster or with the image for cluster.
Staging – An operation that reduces the time ESXi hosts spend in maintenance mode. When you stage an image or baseline to an ESXi host, vSphere Lifecycle Manager downloads the respective bulletins or components from the vSphere Lifecycle Manager depot to the host without applying them immediately. Staging makes the components, patches, and extensions available locally on the hosts. You can choose to remediate the hosts at a later time, not immediately after staging.
Objective 5.9.1 – Update (Upgrade) Virtual Machines
Whether you perform an upgrade of the virtual machine hardware version or the VMware Tools version, the upgrade is a multi-stage process.
- You check the status of individual virtual machines or a container object – vSphere Lifecycle Manager checks the status of a virtual machine against the latest virtual machine hardware version supported by the host on which the virtual machine runs. Similarly, vSphere Lifecycle Manager checks the status of the virtual machine against the latest VMware Tools version supported by the host on which the virtual machine runs.
- You review the status of the scanned virtual machines.
- You upgrade the virtual machine to match the host where it resides.
With vSphere Lifecycle Manager, you can upgrade the virtual machine hardware version and the VMware Tools version that a virtual machine has. You can use vSphere Lifecycle Manager to upgrade the virtual machine hardware version to the latest hardware version, vmx-19, and to the latest VMware Tools version on the hosts.
Objective 5.9.2 – Update ESXi hosts
