EPIC BRIDGES EXAM 300 QUESTIONS AND CORRECT
ANSWER WITH RATIONALE ALREADY GRADED A+
LATEST UPDATE
This 300-question multiple-choice examination is a comprehensive
preparation resource for the Epic Bridges Exam. It covers the full
architecture of Epic's interface engine, including Chronicles, daemons (Event,
Communication, Filer), queues (Data, Control, Event, Holding), Interconnect,
HL7 v2 messaging standards, X12 and FHIR protocols, Interface Monitor,
Background Monitor, error logging, message actions (Resubmit, Retrigger,
Skip), patient identity validation, Data Courier migration, and Sherlock
documentation. Each question includes a detailed rationale reinforcing
correct interface configuration, troubleshooting, and integration workflows.
This resource is ideal for Epic analysts, integration engineers, and healthcare
IT professionals preparing for Epic Bridges certification and proficiency
exams.
1. What is the primary role of Chronicles in Epic Bridges architecture?
A) Routing messages between interfaces
B) Storing all clinical and administrative data
C) Managing TCP/IP connections
D) Translating HL7 segments
Answer: B
Rationale: Chronicles is Epic's relational database that holds the patient record and
all other system data; Bridges reads from and writes to Chronicles .
2. Which daemon is responsible for constructing HL7 messages after a trigger
fires?
A) Communication Daemon
B) Event Daemon
C) Filer Daemon
D) Queue Daemon
Answer: B
Rationale: The Event Daemon picks up the trigger, assembles the message content,
and places it on the Data Queue .
,3. What does the Communication Daemon primarily manage?
A) Translation of external codes
B) Database commits
C) TCP/IP socket connections and ACK/NACK handling
D) Queue depth monitoring
Answer: C
Rationale: The Communication Daemon opens network sockets, sends messages,
and processes acknowledgments .
4. Which queue holds instructions for the next processing step rather than message
content?
A) Data Queue
B) Control Queue
C) Holding Queue
D) Event Queue
Answer: B
Rationale: The Control Queue contains control records such as "process" or "skip"
that guide daemon actions .
5. In the outbound flow, which component directly places the message onto the
network?
A) Event Daemon
B) Data Queue
C) Communication Daemon
D) Filer Daemon
Answer: C
Rationale: After the message is built and queued, the Communication Daemon
pulls it from the queue and transmits it .
6. Which segment in an HL7 v2 message carries patient demographic information?
A) MSH
B) PID
C) PV1
D) ORC
Answer: B
Rationale: PID (Patient Identification) contains name, ID, DOB, gender, and other
demographics .
7. What delimiter separates fields in a standard HL7 v2 message?
,A) '|' (pipe)
B) '^' (caret)
C) '~' (tilde)
D) '\' (backslash)
Answer: A
Rationale: The pipe character separates fields in HL7 v2 messages. The caret
separates components, tilde separates repetitions, and backslash is the escape
character .
8. The "Resubmit" utility in Bridges does what?
A) Creates a new trigger definition
B) Sends the same message again after correction without rebuilding it
C) Deletes the message from the queue
D) Changes the communication protocol
Answer: B
Rationale: Resubmit reprocesses the existing message after a fix, using the same
content .
9. What does the "Retrigger" function accomplish?
A) Restarts the Communication Daemon
B) Rebuilds a fresh message from current Chronicles data
C) Clears all error thresholds
D) Sends a test message to the vendor
Answer: B
Rationale: Retrigger regenerates the message using the latest patient data, ensuring
up-to-date content .
10. Which of the following best describes a "Skip Message" operation?
A) Deleting the message from Chronicles
B) Bypassing a problematic entry in the Control Queue so processing continues
C) Encrypting the message payload
D) Changing the message type from ADT to ORM
Answer: B
Rationale: Skip Message tells Bridges to ignore a specific control record and move
on .
11. In the Interface Monitor, what does a high "Queue Depth" indicate?
A) Many messages are waiting to be processed
B) The daemon is offline
C) A network timeout occurred
, D) The database is full
Answer: A
Rationale: Queue Depth shows the number of messages waiting to be processed; a
high number may indicate a bottleneck or issue .
12. What is the function of the Filer Daemon?
A) Translates HL7 data into something that can be stored in the database
B) Manages TCP/IP connections
C) Builds HL7 messages
D) Creates trigger definitions
Answer: A
Rationale: The Filer Daemon translates HL7 data into a format that can be stored
in Chronicles .
13. What is a Trigger in Epic Bridges?
A) A single, clearly defined action that generates an interface message
B) A database record that stores patient data
C) A network protocol for sending messages
D) An error logging tool
Answer: A
Rationale: A trigger is a single, clearly defined action that a user or process can
take that results in an interface message being created and sent .
14. To identify a patient using identity, you need the _____ and the _____.
A) ID type and ID
B) Name and Date of Birth
C) Social Security Number and Address
D) Medical Record Number and Account Number
Answer: A
Rationale: To identify a patient using identity, you need the ID type and ID .
15. What are the 3 types of patient validation an interface can use?
A) Basic Validation, Extended Validation, Identity Duplication Configuration
(IDC)
B) Simple, Complex, and Advanced
C) Primary, Secondary, and Tertiary
D) Local, Remote, and Hybrid
Answer: A
Rationale: The three types of patient validation an interface can use are Basic
Validation, Extended Validation, and Identity Duplication Configuration (IDC) .
