A company is implementing 'Split Horizon DNS' for their Remote Workers.
Select TWO reasons why Split Horizon DNS is critical for a successful Avaya Aura Remote Worker deployment.
Show answer details
Correct answer: A, D
Split Horizon DNS allows the same FQDN (e.g., sip.company.com) to resolve to different IP addresses depending on where the query originates. Internal users must resolve to the internal Session Manager, while external (remote) users must resolve to the SBCE public interface.
Security is a key factor. External clients should only know the public IP of the SBCE. Exposing internal IP addresses of Session Managers or other core components via public DNS would be a security risk.

An administrator is reviewing the 'Replication' page in System Manager and notices that one of the Session Manager nodes has a status of 'Synchronization Failed'.
What is the first step the administrator should take to attempt to resolve this without impacting service?
Show answer details
Correct answer: C
The 'Repair' function in the Replication page triggers a resynchronization of the database from System Manager to the selected Session Manager node. This is the standard first step for sync failures before attempting more invasive actions like rebuilding the replica or rebooting.

A user reports they can hear the other party, but the other party cannot hear them (one-way audio). A trace shows that the RTP stream from the user is being sent to an IP address that is not reachable by the Media Gateway.
Which protocol in the SIP negotiation is responsible for advertising the IP address and port where media should be sent?
Show answer details
Correct answer: B
SDP (Session Description Protocol) is carried within the body of SIP messages (like INVITE or 200 OK). It describes the media capabilities, including the IP address (c= line) and port (m= line) where the endpoint expects to receive audio.
- 4
When configuring Avaya Aura Media Server (AAMS) to work with Communication Manager, which signaling group type must be created in Communication Manager?
Show answer details
Correct answer: B
The Avaya Aura Media Server (AAMS) connects to Communication Manager using SIP. Therefore, a SIP signaling group and a corresponding SIP trunk group must be configured in CM to utilize AAMS resources.
- 5
Which trace log on the Avaya Session Border Controller (SBCE) is most useful for troubleshooting TLS handshake failures during the initial connection setup with a remote endpoint?
Show answer details
Correct answer: C
In the SBCE, the
ipcs.log(often viewed via the traceSBC tool or directly in the archive) contains detailed signaling and connection events, including TLS handshake errors, certificate validation failures, and socket connection details. - 6
A support engineer is troubleshooting a reported issue where calls from a specific SIP entity are failing to route through the Avaya Aura Session Manager (SM). Upon checking the Session Manager Dashboard, the engineer notices the Entity Link status is 'down'.
Which of the following conditions would most likely cause the Entity Link to transition to a 'down' state while the network connectivity remains intact?
Show answer details
Correct answer: A
Session Manager uses SIP OPTIONS messages to monitor the health of Entity Links. If SM sends OPTIONS requests and does not receive a 200 OK (or other acceptable response) within the configured timeout/retry limits, it marks the link as down, even if Layer 3 connectivity exists. This is a logic-layer health check.

In an Avaya Aura environment, a user reports that when they make an outbound call, the call setup takes unusually long, but eventually connects. A trace reveals that the Session Manager is attempting to contact a Communication Manager instance that is currently out of service before failing over to the active one.
What configuration element in Avaya Aura System Manager controls the selection order of SIP Entities to preventing this delay?
Show answer details
Correct answer: B
In the Routing Policy configuration, administrators assign a Rank to each SIP Entity. Session Manager attempts to route calls to the entity with the lowest rank number first (e.g., Rank 0 before Rank 1). If the primary is down but listed with a lower rank (better priority), SM waits for a timeout before trying the next. Proper maintenance of ranks or using Local Host Name Resolution for active status is key.

A multinational corporation uses a centralized Avaya Aura core with local trunking in regional branches. The administrator needs to ensure that emergency calls from the 'Paris' branch route specifically to the Paris PSTN gateway, while general calls follow least cost routing.
Which combination of Avaya Aura System Manager objects must be configured to achieve location-specific routing for the same dialed number string?
Show answer details
Correct answer: C, D
Dial Patterns are the mechanism where the decision is made. Inside a Dial Pattern, you can specify 'Originating Location' to trigger different Routing Policies for the same pattern.
Location-based routing requires defining Locations (based on IP subnets) and associating specific Routing Policies to those Locations within the Dial Pattern. This allows the same dialed string (e.g., 911 or 112) to route differently depending on the caller's IP subnet.

During a maintenance window, a technician observes the sequence of Application processing for a SIP user in Session Manager. The user is configured with Communication Manager (CM) as a sequenced application.
Which diagram correctly represents the logical flow of a call originating from a SIP Endpoint, passing through Session Manager to CM for feature processing, and returning to Session Manager for routing?
Show answer details
Correct answer: D
In an Originating Application Sequence, the SIP INVITE flows from the Endpoint -> Session Manager -> Communication Manager (for features) -> Session Manager -> Routing decision. Session Manager acts as the orchestrator, routing the call to the application (CM) and receiving it back before final routing.

A support team is investigating a '403 Forbidden' error when an external SIP trunk provider attempts to send a call to the enterprise Avaya Session Border Controller for Enterprise (SBCE). The trace shows the SBCE rejecting the packet immediately.
Which configuration on the SBCE is the most likely cause for this rejection?
Show answer details
Correct answer: B
SBCE enforces strict topology hiding and access control. If an incoming request originates from an IP address that is not defined as a known Remote Entity (Server), the SBCE treats it as unauthorized traffic and drops or rejects it with a 403 Forbidden to protect the network.
