If EMS server does not receive heartbeats from a client for a period exceeding 10 seconds, the EMS server will close the connection.

dbstore driver dialect
Which three steps should be taken to avoid losing routed topic messages? (Choose three)
Use durable subscribers instead of non-durable subscribers
Send persistent messages
Create active-active routes
Which statement is true about EMS mstore?
It can help recover quickly after a failover.
There is a non-fault-tolerant server running on a host named SERVER_A. There are two other servers running on the hosts FT_PRIM and FT_BACK configured as a fault-tolerant pair using shared state. FT_PRIM runs the primary server, and FT_BACK runs the backup server. Which statement is true about these servers?
The SERVER_A server can create a route to the fault-tolerant pair.
Which three commands must be executed to ensure that user ui can only send messages to queue qi? (Choose three.)
set server authorization=enabled
grant queue q1 user =u1 send
addprop queue q1 secure
Which two statements are true about load balancing with EMS? (Choose two.)
EMS servers should not be load balanced with durable subscribers.
Load balancing should be avoided when the application requires strict message ordering.
Atopic sales, topic is bridged to two queues: FINANCE.Q and AUDIT.Q. Ten messages are sent on the topic SALES.TOPIC. A consumer reads ten messages from FINANCE.Q. How many messages are now in the AUDIT.Q?
When a single message consumer is connected with an EMS server, which action can be used to improve message consumption?
Increasing the prefetch value
Which two statements are true about message selectors? (Choose two.)
They can be applied on bridges and routes.
They can be applied only on header and properties of the message.
Which section is required in a JMS message?
Which two statements are true about JNDI lookups of EMS administered objects? (Choose two.)
The EMS server and third-party naming/directory services automatically synchronize administered objects,
Dynamic topics are automatically added to the third-party naming/directory service.
What is the command to modify an existing route?
setprop route <route name> outgoing_topic=topicName selector="msg-selector"
Which server parameter in the tibemsd. conf file allows confirmation of NON_PERSISTENT messages to the producer when authorization is disabled in the server?
What are two characteristics of multicasting? (Choose two.)
Multicasting is used in messaging scenarios where high bandwidth delivery of real-time data is a requirement,
The producer can choose to use PGM or TCP to send messages to the EMS server,
Which two datastores are supported by EMS servers? (Choose two.)
What are two valid EMS Message types? (Choose two.)
Object Message with a serializable Java object
Which two objects are referred to as EMS administered objects? (Choose two.)
You have a routed queue named ORDER. NEW defined between the US-EMS (home queue) and MEXICO-EMS servers What must be done for messages to route properly?
Send a message to the queue named ORDER, NEW
Which method can be used to create custom authorization login modules?
Which three commands will update EMS configuration files when an exclusive commit command is issued from EMS? (Choose three.)
set server password=password
set server authorization=enabled
set server track_message_ids=enabled
Which parameter must be configured for primary and secondary EMS to operate in fault-tolerant mode?
server parameter in the tibemsd.conf file
Which two statements are true about RELIABLE_DELIVERY mode? (Choose two.)
It is a TIBCO extension to JMS.
Reliable mode decreases the volume of message traffic, allowing higher message rates.
Which two statements are true about configuring security for a fault-tolerant pair that does not share state? (Choose two.)
When SSL is deployed, both servers must use the same certificate(s).
All access control settings should be the same on both servers.
There is a non-fault tolerant EMS server running on a host named SERVER_A. There are two other EMS servers running on the hosts FT_PRIM and FT_BACK configured as a fault-tolerant pair using shared state. FT_PRIM runs the primary EMS server and FT_BACK runs the backup EMS server. Which two statements are true about these servers? (Choose two.)
The EMS server names (in tibemd.conf) must be the same on host FT_PRIM and FT_BACK.
The SERVER_A EMS server can create a route to the fault-tolerant pair.
Which two are valid acknowledgment modes in TIBCO Enterprise Message Service? (Choose two.)
What are three limitations in the use of wildcards by EMS clients? (Choose three.)
Clients cannot send to wildcard queues.
Clients cannot receive from wildcard queues.
Clients cannot publish to wildcard topics.
Which two conditions can cause messages in a queue to be moved to the undelivered queue? (Choose two.)
The number of delivery attempts has reached the limit defined for the queue.
The length of time the message has been retained in the queue has exceeded the limit defined for the queue.
Which two statements are true about the listen parameter? (Choose two.)
The listen parameter is set in the tibemsd.conf file.
Multiple listen parameters can be set in the TIBCO EMS configuration file.
Which two permissions can be granted to users to access queues? (Choose two.)
Which three entries are valid in the aci.conf file? (Choose three.)
ADMIN USER=userl PERM=all
TOPIC=foo USER=user2 PERM=publish
ADMIN user=user4 PERM=view-durable
Which Administration Tool command creates the queue without reporting any errors?
Create queue test.queue secure,global,store=Ssys.failsafe
Which statement is true when clients send messages to EMS servers using RELIABLE_DELIVERY mode?
The publish call succeeds unless the EMS server connection has terminated.
What are two characteristics of topics and queues? (Choose two.)
A queue cannot have multiple receivers connected at the same time
A topic publisher can send to wildcard topics.
Which two parts are optional in JMS Message Structure? (Choose two.)
Which two statements are true about selector functions? (Choose two.)

They are available to control the flow of messages along a route.
Which command displays message count delivered to a queue receiver?
Which two statements are true about hops and zones in EMS? (Choose two.)
Topic messages can be routed across multiple hops if there are no cycles.
A server can simultaneously belong to more than one zone.
