Practice Test 1 | Google Cloud Certified Professional Data Engineer | Dumps | Mock Test
You launched a Dataproc cluster to perform some Apache Spark jobs. You are looking for a method to securely transfer web traffic data between your machine’s web browser and Dataproc cluster.
How can you achieve this?
A. FTP connection
B. SSH tunnel
C. VPN connection
D. Incognito mode
Answer: B.
Some of the core open source components included with Google Cloud Dataproc clusters, such as Apache Hadoop and Apache Spark, provide web interfaces. These interfaces can be used to manage and monitor cluster resources and facilities, such as the YARN resource manager, the Hadoop Distributed File System (HDFS), MapReduce, and Spark. Other components or applications that you install on your cluster may also provide web interfaces.
It is recommended to create an SSH tunnel for a secure connection between your web browser and Dataproc’s master node. SSH tunnel supports traffic proxying using the SOCKS protocol. To configure your browser to use the proxy, start a new browser session with proxy server parameters.
