156-315.81.20 Gateway Deployment and Upgrades Practice Question
You are upgrading a Security Gateway from R80.40 to R81.20 using the CPUSE Web UI. After selecting the upgrade package, you are prompted to choose between 'Upgrade' and 'Clean Install'. You want to preserve the existing configuration and installed hotfixes. Which option should you select?
⚠ Common exam trap
Many exam-takers confuse backup or migration methods with the actual upgrade choices, leading to data loss or unnecessary reconfiguration.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Upgrade
When using CPUSE to upgrade, the 'Upgrade' option performs an in-place upgrade that retains the existing configuration and compatible hotfixes. 'Clean Install' erases everything, while 'Export and Import' and 'Snapshot and Restore' are not upgrade methods. For preserving settings, 'Upgrade' is the correct selection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Clean Install
Why it's wrong here
A 'Clean Install' wipes the existing configuration and installs a fresh copy of the operating system and software. This would erase all settings, requiring manual reconfiguration and policy reinstallation. It is used when a fresh start is desired or when upgrading from a significantly different version, not for preserving configuration.
- ✗
Snapshot and Restore
Why it's wrong here
Snapshot and Restore is a backup mechanism, not an upgrade method. Taking a snapshot before upgrading is a best practice, but it does not perform the upgrade itself. Selecting this would not advance the upgrade process and would leave the gateway on the current version.
- ✗
Export and Import
Why it's wrong here
Export and Import is a separate process for migrating configuration between different appliances or after a clean install. It is not an option presented during a standard CPUSE upgrade. While it can preserve settings, it is more manual and not the direct choice for an in-place upgrade.
- ✓
Upgrade
Why this is correct
The 'Upgrade' option in CPUSE preserves the existing configuration, including network settings, policies, and installed hotfixes where compatible. This is the correct choice when you want to retain the current setup and minimize downtime. It performs an in-place upgrade, migrating settings to the new version.
