Question

A corporate jump server located in the public cloud was terminated overnight because the underlying hardware failed. The next morning, developers were unable to reach environments. Which of the following is the best way to remediate the issue?

  • BProvisioning and configuring a new jump server via a cloud console
  • CRecommending developers use their laptops for development
  • DConfiguring autoscaling with a minimum number of jump servers set to one

Why each option

A terminated jump server requires immediate manual reprovisioning to restore developer access to cloud environments.

ASetting up a virtual load balancer in front of a jump server

A load balancer distributes traffic across multiple servers but cannot route to a jump server that no longer exists.

BProvisioning and configuring a new jump server via a cloud consoleCorrect

Provisioning a new jump server via the cloud console directly restores the access path that developers require. Cloud consoles allow on-demand instance creation with the same networking, security groups, and access controls as the original. This is the fastest remediation because it addresses the root cause - the absence of the jump server itself.

CRecommending developers use their laptops for development

Having developers use their laptops bypasses established security controls and does not restore the intended secure access architecture.

DConfiguring autoscaling with a minimum number of jump servers set to one

Configuring autoscaling with a minimum of one instance prevents future recurrence but does not immediately restore access to the already-terminated server.
