1. Question 1Operations and support

   A monitoring system shows that a database server's disk usage is growing about 5 percent each day. What should the cloud administrator do first?

   1. AReboot the database server every night during the maintenance window to free disk space
   2. BCreate an alert threshold and project when capacity will be exhausted, then plan expansion or cleanup
   3. CDelete the database logs immediately without checking their retention needs first
   4. DLeave the alert unacknowledged and ignore the growth trend until the disk reaches full capacity and writes fail
   Show answer and explanationHide answer

   Correct answer: B

   Trend-based alerting gives lead time to expand capacity or clean up data deliberately. Waiting until the disk is full causes an outage, and deleting logs or rebooting without analysis may remove needed data or do nothing lasting.

2. Question 2Cloud architecture

   A company runs a web application that must survive the failure of one data center within the same region. Which design meets this need with the least change to the application?

   1. ADeploy a second copy in a different cloud region with manual failover
   2. BDeploy instances across two availability zones behind a load balancer
   3. CIncrease the size of the single virtual machine
   4. DMove the database to a single larger server in the same zone
   Show answer and explanationHide answer

   Correct answer: B

   Spreading instances across availability zones within a region tolerates a single facility failure, and a load balancer distributes traffic between them. A larger single VM or single zone remains a single point of failure, and a manual cross-region failover is slower than the requirement implies.

3. Question 3Security

   Which two controls reduce the risk of exposing a cloud storage bucket to the public internet? (Choose two.)

   1. AGrant the group 'everyone' read access to simplify sharing
   2. BUse least-privilege identity policies for accounts that access the bucket
   3. CDisable encryption so that public tools can read the objects
   4. DPublish the bucket name on the company website
   5. EEnable the account-level public access block for storage
   Show answer and explanationHide answer

   Correct answer: B, E

   An account-level public access block prevents public exposure regardless of object policies, and least-privilege identity policies limit who can read. Public groups, disabled encryption, and publishing names all increase exposure.

4. Question 4Troubleshooting

   Users in one subnet report that they cannot reach an application server in another subnet, but other subnets can. Which item should the administrator check first?

   1. AThe server's desktop wallpaper and screen saver settings in the profile
   2. BThe shared email address and phone extension of the help desk team on call
   3. CThe network security rules and route table entries that apply to the affected subnet
   4. DThe application's logo image, footer text, and visual branding assets
   Show answer and explanationHide answer

   Correct answer: C

   Connectivity problems confined to one subnet usually come from routing or security rules that apply to that subnet. Application branding and help desk details do not affect network reachability.

5. Question 5Deployment

   A team must deploy a new application version with no downtime and the ability to revert quickly if errors appear. Which strategy is most appropriate?

   1. AEditing production configuration files directly on each web server
   2. BDeploying the release to every server at once without health checks
   3. CBlue-green deployment with traffic switched between two identical environments
   4. DStopping the service, copying new files over the old ones, and restarting it afterward
   Show answer and explanationHide answer

   Correct answer: C

   Blue-green deployment keeps the current version running while the new one is verified, and switching traffic back provides a fast rollback. The other approaches create downtime or remove a safe way to revert.
