Salesforce Certified Heroku Architect (Plat-Arch-206) Exam Practice Test Instant Access

Question 1

How does Heroku Connect work with Salesforce authentication?

AThe end user of a Heroku app authorizes Heroku Connect via OAuth.

BOAuth provides Heroku Connect with API tokens after the user authorizes the Heroku Connect application on Salesforce

CSAML authorizes Heroku Connect to make API calls

DA single integration user's credentials are stored.

Answer : B

Question 2

Universal Containers needs to write their Heroku application's logs to twodestinations: an on-premise Syslog log server and a cloud analytics provider that ingests logs using an HTTPS endpoint.

What should an Architect recommend in this scenario?

APublish all logs to Apache Kafka on Heroku, and create a separate app thatconsumes and distributes log messages.

BWrite all logs to Heroku Redis as a buffer and use an add-on to send them to both destinations.

CAdd a logging library to the application source that sends all logs directly to both destinations.

DWrite all logs to stdout, and configure a separate log drain for each destination.

Answer : D

Question 3

A client wants to create a scalable set of microservices that communicate with each other, where multiple microservices have a public REST API.

Which architecture strategy allows this on Heroku?

AEach microservice is a separate Heroku app. The microservices communicate byusing Apache Kafka as a message bus.

BEach microservice is a separate process type in a single Heroku app. The microservices communicate by using Redis as a message bus.

CEach microservice is a separate private space. The microservices communicate byusing DNS Service Discovery.

DEach microservice is a separate process in a single Heroku app. The microservices communicate by using shared memory.

Question 4

An existing app is experiencing performance degradation because of multiple executions of multiple, expensive SQL read queries. This SQL code cannot be optimized any further and the frequency of the execution of the queries cannot be reduced. Which two options should an Architect recommend in this scenario?

AHardcode the results of the query into app logic

BAdd a read-only HerokuPostgres follower

CCreate a database caching layer

DRestart the Heroku Postgres server to reclaim cache

Question 5

Universal Containers (UC) usesHeroku Connect to synchronize changes to the Account object in their Salesforce org. UC's Heroku application makes a batch update that changes one million records to the Heroku Postgres database table that mirrors the Account object. Approximately, how long will these updates take to sync back to the Salesforce org?

AIt depends on the sync performance, which can vary from one connection to another.

B1 hour.

COne million updates is too many for Heroku Connect to handle; therefore, the sync will fail

D12 hours.

Question 6

A client requires that their web application's logs are accessible only from within the same isolatednetwork as the application itself.

Which solution should an Architect recommend in this scenario?

ADeploy the application to a Private Space. Provide the Private Space's stable outbound IPs to Heroku's Logplex router to block all logs originating fromthe Private Space.

BDeploy the application to a Shield Private Space with Private Space Logging enabled. Forward logs to a destination within the Shield Private Space.

CDeploy the application to a Private Space. Connect the Private Space to an on-premise logging system using VPN and specify it as a log drain.

DDeploy the application to a Private Space. Enable Internal Routing to prevent the application's logs from being forwarded outside of the Private Space.

Answer : C

Question 7

A client has 3 Heroku applications: App 1, App 2, App 3. They would like to restrict external web traffic to App 3 only. Which two Heroku features should an Architect recommend to enable this architecture?

AVPC Peering

BTrusted IP ranges

CPrivate Spaces

DInternal Routing

Answer : B
