Question No. 1

Your company's logo is published as an image file across multiple websites that are hosted by your company You have implemented Cloud CDN, however, you want to improve the performance of the cache hit ratio associated with this image file. What should you do?

AConfigure custom cache keys for the backend service that holds the image file, and clear the Host and Protocol checkboxes-

BConfigure Cloud Storage as a custom origin backend to host the image file, and select multi-region as the location type

CConfigure versioned IJRLs for each domain to serve users the *mage file before the cache entry expires

DConfigure the default time to live (TTL) as O for the image file.

Show Answer

Correct Answer: A

This answer meets the requirement of improving the performance of the cache hit ratio associated with the image file. The reason is:

Custom cache keys allow you to control which parts of the request URL are used to build the cache key.The cache key is a unique identifier that Cloud CDN uses to store and retrieve cached content1.

By default, Cloud CDN uses the complete request URL, including the protocol (http or https) and the host (the domain name), to build the cache key.This means that if the same image file is requested from different domains or protocols, Cloud CDN will cache multiple copies of it, which reduces the cache hit ratio1.

By clearing the Host and Protocol checkboxes, you can tell Cloud CDN to ignore these parts of the request URL when building the cache key.This way, Cloud CDN will cache only one copy of the image file, regardless of which domain or protocol it is requested from, which improves the cache hit ratio1.

Option B is incorrect because configuring Cloud Storage as a custom origin backend does not affect the cache hit ratio. It only affects how Cloud CDN retrieves the content from the origin if it is not cached. Option C is incorrect because configuring versioned URLs for each domain does not improve the cache hit ratio. It actually worsens it, because it creates more variations of the request URL that Cloud CDN has to cache separately. Option D is incorrect because configuring the default TTL as 0 for the image file means that Cloud CDN will not cache it at all, which defeats the purpose of using Cloud CDN.

Question No. 2

You are using a 10-Gbps direct peering connection to Google together with the gsutil tool to upload files to Cloud Storage buckets from on-premises servers. The on-premises servers are 100 milliseconds away from the Google peering point. You notice that your uploads are not using the full 10-Gbps bandwidth available to you. You want to optimize the bandwidth utilization of the connection.

What should you do on your on-premises servers?

ATune TCP parameters on the on-premises servers.

BCompress files using utilities like tar to reduce the size of data being sent.

CRemove the -m flag from the gsutil command to enable single-threaded transfers.

DUse the perfdiag parameter in your gsutil command to enable faster performance: gsutil perfdiag gs://[BUCKET NAME].

Question No. 3

You have an application that is running in a managed instance group. Your development team has released an updated instance template which contains a new feature which was not heavily tested. You want to minimize impact to users if there is a bug in the new template.

How should you update your instances?

AManually patch some of the instances, and then perform a rolling restart on the instance group.

BUsing the new instance template, perform a rolling update across all instances in the instance group. Verify the new feature once the rollout completes.

CDeploy a new instance group and canary the updated template in that group. Verify the new feature in the new canary instance group, and then update the original instance group.

DPerform a canary update by starting a rolling update and specifying a target size for your instances to receive the new template. Verify the new feature on the canary instances, and then roll forward to the rest of the instances.

Question No. 5

You configured Cloud VPN with dynamic routing via Border Gateway Protocol (BGP). You added a custom route to advertise a network that is reachable over the VPN tunnel. However, the on-premises clients still cannot reach the network over the VPN tunnel. You need to examine the logs in Cloud Logging to confirm that the appropriate routers are being advertised over the VPN tunnel. Which filter should you use in Cloud Logging to examine the logs?

Aresource.type= ''gce_router''

Bresource.type= ''gce_network_region''

Cresource.type= ''vpn_tunnel''

Dresource.type= ''vpn_gateway''
