Question: 1

Some of your production services are running in Google Kubernetes Engine (GKE) in the eu-west-1 region. Your build system runs in the us-west-1 region. You want to push the container images from your build system to a scalable registry to maximize the bandwidth for transferring the images to the cluster. What should you do?

APush the images to Google Container Registry (GCR) using the gcr.io hostname.

BPush the images to Google Container Registry (GCR) using the us.gcr.io hostname.

CPush the images to Google Container Registry (GCR) using the eu.gcr.io hostname.

DPush the images to a private image registry running on a Compute Engine instance in the eu-west-1 region.

Question: 2

You encounter a large number of outages in the production systems you support. You receive alerts for all the outages that wake you up at night. The alerts are due to unhealthy systems that are automatically restarted within a minute. You want to set up a process that would prevent staff burnout while following Site Reliability Engineering practices. What should you do?

AEliminate unactionable alerts.

BCreate an incident report for each of the alerts.

CDistribute the alerts to engineers in different time zones.

DRedefine the related Service Level Objective so that the error budget is not exhausted.

Question: 3

You need to reduce the cost of virtual machines (VM| for your organization. After reviewing different options, you decide to leverage preemptible VM instances. Which application is suitable for preemptible VMs?

AA scalable in-memory caching system

BThe organization's public-facing website

CA distributed, eventually consistent NoSQL database cluster with sufficient quorum

DA GPU-accelerated video rendering platform that retrieves and stores videos in a storage bucket

Question: 4

You are part of an organization that follows SRE practices and principles. You are taking over the management of a new service from the Development Team, and you conduct a Production Readiness Review (PRR). After the PRR analysis phase, you determine that the service cannot currently meet its Service Level Objectives (SLOs). You want to ensure that the service can meet its SLOs in production. What should you do next?

Adjust the SLO targets to be achievable by the service so you can bring it into production.

BNotify the development team that they will have to provide production support for the service.

CIdentify recommended reliability improvements to the service to be completed before handover.

DBring the service into production with no SLOs and build them when you have collected operational data.

Question: 5

Your product is currently deployed in three Google Cloud Platform (GCP) zones with your users divided between the zones. You can fail over from one zone to another, but it causes a 10-minute service disruption for the affected users. You typically experience a database failure once per quarter and can detect it within five minutes. You are cataloging the reliability risks of a new real-time chat feature for your product. You catalog the following information for each risk:

* Mean Time to Detect (MUD} in minutes

* Mean Time to Repair (MTTR) in minutes

* Mean Time Between Failure (MTBF) in days

* User Impact Percentage

The chat feature requires a new database system that takes twice as long to successfully fail over between zones. You want to account for the risk of the new database failing in one zone. What would be the values for the risk of database failover with the new system?

A.

MTTD: 5

MTTR: 10

MTBF: 90

Impact: 33%

B.

MTTD:5

MTTR: 20

MTBF: 90

Impact: 33%

CMTTD:5
MTTR: 10
MTBF: 90
Impact 50%
D.
MTTD:5
MTTR: 20
MTBF: 90
Impact: 50%
