Configure Phase 2 of the IPsec VPN tunnel.

1. (Optional) Configure a custom IPsec Phase 2 proposal. This step is optional, as you can use a predefined IPsec Phase 2 proposal set (Standard, Compatible, or Basic).
2. Configure an IPsec policy that references either your custom IPsec Phase 2 proposal or a predefined IPsec Phase 2 proposal set. Specify perfect forward secrecy (PFS) keys.
3. Configure an IPsec VPN tunnel that references both the IKE gateway and the IPsec policy. Specify the proxy IDs to be used in Phase 2 negotiations.

   (For route-based VPNs) Bind the secure tunnel interface st0.x to the IPsec VPN tunnel.

Where do stratum 1 NTP servers get time from?

Where do stratum 1 NTP servers get time from?

• A stratum 2 clock
• A reference clock
• They generate it internally 

 

EXPLANATION

Stratum 1 NTP servers are the highest, most trusted order of NTP servers. They receive their time by being directly connected to a reference clock, typically an atomic clock. Reference clocks are also referred to as stratum 0 devices.

What we use to increase the random access memory (RAM) capacity of a running virtual machine (VM) without downtime in vSphere setting

What we use to increase the random access memory (RAM) capacity of a running virtual machine (VM) without downtime in vSphere setting

• memory hot-add
• cpu-hotplug
• drive hot-plug
• cpu hot-add 

 

 

EXPLANATION

VMware vSphere hot add is a feature that allows an administrator to increase the random access memory (RAM) capacity of a running virtual machine (VM) without downtime

VSphere hot add can be enabled during the configuration of VMware VMs running hardware version 7 and newer, on compatible OSes and with the use of VMware Tools. Because vSphere hot add is disabled by default, and VMs must be powered off to enable it, administrators should consider enabling hot add from the start if there's a possibility that a VM will need more resources at any point.
