   You host a static website on Cloud Storage. Recently, you began to include links to PDF files on this site. Currently, when users click on the links to these PDF files, their browsers prompt them to save the file onto their local system. Instead, you want the clicked PDF files to be displayed within the browser window directly, without prompting the user to save the file locally. What should you do?

   • AEnable Cloud CDN on the website frontend.
   • BEnable 'Share publicly' on the PDF file objects.
   • CSet Content-Type metadata to application/pdf on the PDF file objects.
   • DAdd a label to the storage bucket with a key of Content-Type and value of application/pdf.

   Show answer

   Answer: C

   Explanation

   ANSWER A, enabling Cloud CDN on the website frontend, is not relevant to displaying PDF files in the browser. Cloud CDN is a content delivery network that caches content at edge locations around the world to reduce latency and improve website performance. ANSWER B, enabling "Share publicly" on the PDF file objects, only controls whether or not the files are accessible to users without authentication. It does not affect how the files are displayed in the browser. ANSWER D, adding a label to the storage bucket with a key of Content-Type and value of application/pdf, is not the correct way to set the Content-Type metadata for individual objects. Labels are used for organizing resources, while metadata is used to provide information about the data itself. Therefore, ANSWER C, setting Content-Type metadata to application/pdf on the PDF file objects, is the correct answer.

   You have a virtual machine that is currently configured with 2 vCPUs and 4 GB of memory. It is running out of memory. You want to upgrade the virtual machine to have 8 GB of memory. What should you do?

   • ARely on live migration to move the workload to a machine with more memory.
   • BUse gcloud to add metadata to the VM. Set the key to required-memory-size and the value to 8 GB.
   • CStop the VM, change the machine type to n1-standard-8, and start the VM.
   • DStop the VM, increase the memory to 8 GB, and start the VM.

   Show answer

   Answer: D

   Explanation

   D is correct. If you pay attention to the question, option C mentions n1-standard-8. That instance type has 8vCPUs and 30 GB RAM, and we only need 8GB. On top of that, it is possible to use custom machine type to adjust current VM RAM to the value we need. Got the answer from this course I did to prepare the exam: https://www.udemy.com/course/google-cloud-associate-engineer-exam-practice-tests/?couponCode=21CDE6A4C2B95F79BD97 good luck!

   Show answer

   Answer: B

   Explanation

   This question is designed to waste your time during the exam by making you read all those long answers. Remember that part of exam technique is not about knowing the product at all, but understanding multiple choice questions. For example when two answers are very similar to each other, this can increase the likelihood that the correct answer is one of those two. In this case it's an easy process of elimination as all answers are similar, we just need to filter out the wrong ones (and whacking the wrong answer in an exam is sometimes the best way to find the right one). Two answers mention port 8080, and two mention all ports. Obviously we just need port 8080, so we can immediately eliminate those two questions that want all ports open. That gives us a 50/50 chance of getting this question right. Of the remaining answers, one says "ingress" and the other "egress". We know that by default egress is permitted and ingress is not, so that makes "b" the only surviving choice.
