Which network feature could help a company meet its goals to expand service to Asia while reducing latency? HTTP/TCP load balancing, network TCP/UDP, Cloud Router, or Cloud Content Delivery Network (CDN). The answer is D, Cloud Content Delivery Network (CDN). CDN will enable a company to expand its online presence with a single IP address and global reach, leveraging Google's global network. While global load balancing is part of CDN, it won't help reduce latency to customers in Asia, whereas the cache service in CDN will do that. Network load balancing is designed to load balance from one GCP service to another to scale back end services, which is called east-west communications. North-south communications, where one part is in the GCP network and the other part is external, requires a different kind of load balancing. Cloud Router uses BGP to discover changes in network topology in a remote network, so it doesn't address latency. How can you minimize the cost of storing security video files that are processed repeatedly for 30 days? First, Regional class, then move to Coldline after 30 days; next, Nearline class, then move to Coldline after 30 days; Regional class, then move to Nearline after 30 days; or Multi-Regional class, and then move to Coldline after 30 days? The answer is A, Regional class, then move to Coldline after 30 days. The question here is answered by understanding the purpose of each of the storage classes and, in general, how they're priced. One thing to remember is that Coldline is really not intended to be read more than once a year. It's cheap to write data to it, but much more to read it back, compared to the other classes of storage. So the correct answer is A, local usage in a regional bucket for initial use during the month, then Coldline because it's unlikely to be read after that. This is often the case when data is used during the month and archived for compliance and record keeping after. The other options will not be cost effective.
