Question10: Session Manager uses five unique certificates for TLS connections.
What are the two most important certificates in communicating with other devices/entities? (Choose two.)

Question11: Which two SIP requests are used to allow an AST endpoint to use features provided by an Avaya Aura ® Communication Manager (CM)? (Chose two).

Question12: A customer has just added a CS1000 SIP Entity and Entity Link using TLS port 5061. Users are unable to call any Avaya Aura® users which are connected via the same Avaya Aura® Session Manager (SM).
They have run a traceSM and see no SIP messages coming from the CS1000 in the trace. They can ping between the CS1000 and SM100.
Which two traces or logs are most relevant to debugging this problem and should be included in the trouble ticket raised with Tier 3 support? (Choose two.)

Question13: When one Avaya SIP Telephone (AST) user calls another Avaya SIP Telephone (AST) user agent, Session Manager goes through different phases of processing the call.

Question14: Which two methods are used to obtain Avaya Aura® Communication Manager (CM) software version information? (Choose two.)

Question15: How can you view the entire contents of the current Avaya Aura@ Communication Manager CM call processing log file?

Question16: What is the function of a Virtual Network Region?

Question17: A customer reports that several Remote Worker new hires were trying to call co-workers in the office, but noticed their feature buttons were not working. After running a SIP trace, the administrator did not see any PPM Responses coming from Avaya Aura® Communication Manager (CM).
After looking at how the call flow is supposed to go, the administrator looked at the SIP communication profile and saw that CM had not been administered as a sequenced application.
If CM had been added to the endpoint's SIP Communication Profile as a Sequenced Application, which step was missing in the call flow?

Question18: How can you show that a session is actually reaching the Avaya Aura® Media Server (AAMS)?

Question19: A customer called Avaya Support after their telecom administrator was unable to add 50 new telephones for new hires. Avaya support determined that the number of telephones exceeded the capacity the system could support.
Which pre-implementation step was omitted?

Question20: When viewing Avaya Aura® Communication Manager (CM) trusted certificates, you notice that the installed certificates are marked with either A, C, W, or R.
What do these letters stand for?

Question21: Which two statements describe steps for searching for an Avaya Aura® System Manager (SMGR) log containing the phrase 'down'? (Choose two.)

Question22: As opposed to a regular SIP trace, what do SIP messages captured using the traceSM with "a=showSM" option display?

Question23: Which three are Avaya Subscription event packages? (Choose three.)

Question24: How can you check to see if the Avaya Aura® Session Manager (SM) application processes are running?

Question25: A customer calls Avaya Support stating their Session Manager (SM) is down. After doing some troubleshooting the technician sees SM is in the Deny New Service state, and in Restricted license mode.
What does this license mode indicate?

Question26: After implementation, Avaya Aura® Session Manager (SM) replication status is Not Polling, and both replica nodes are not reachable. The network connectivity has been verified, although Avaya Aura® System Manager (SMGR) cannot connect to SM, but can connect other network components.
Based on an analysis of what is working and not working, where should the administrator try to isolate the issue?

Question27: Which Linux command is used to start a previously stopped Communication Manager?

Question28: A customer explains that calls are failing to route from Avaya Aura® Session Manager (SM) A (managed by Avaya Aura® System Manager (SMGR) A) to an Avaya Aura® Session Manager (SM) B (managed by Avaya Aura® System Manager (SMGR) B) When you check the configuration in Avaya Aura® Session Manager (SM) A, witch statement describes what should you look for?

Question29: When observing the Session Manager dashboard, you notice that one entity is marked as down.
Which two troubleshooting tools can be used to investigate the problem? (Choose two.)

Question30: A customer has just configured Avaya Aura® Media Server (AAMS) on their Avaya Aura® Communication Manager (CM). They are saying that the AAMS is never being used by CM, but instead is always using the G450 gateways to provide DSP resources.
The customer has checked the status of the Media Server and the Signaling Group and both show In- Service. They have also checked that a Media Server License is installed on WebLM, and the status of the Media Server is showing Element Status as being normal.
Which statement describes the cause of this problem?

Question31: What are the two types of certificates the Avaya server uses?

Question32: During installation, through the exchange of security certificates, between which three does the Trust Management Service establish trust? (Choose three.)

Question36: Immediately after Registration, how does an Avaya SIP telephone learn if any of its Call Forward features are active right now?

Which command can be used to determine the root cause?

Question38: Which statement describes the steps to save the traceSM log file?

Question39: Which critical Avaya Aura® Communication Manager (CM) information can be obtained from the ECS log located in the /var/log/ecs directory? (Choose two.)

Question40: A customer called Avaya Support stating that shortly after some maintenance work was done, they cannot make or receive calls.
Which command in Avaya Aura® Communication Manager (CM) can the administrator execute, to determine if the H.248 Gateways were placed in a maintenance busy state?

Question41: What is the purpose of a Virtual (Intervening) Network Region?

Question42: Avaya Aura® System Manager (SMGR) holds a copy of the Avaya Aura® Communication Manager (CM) database, and it is important that the database is kept identical in both SMGR and CM.

Question45: Which three statements are true regarding Avaya Aura® 7.x? (choose three.)

Question46: A customer reports that several Remote Worker new hires were trying to call co-workers in the office, but noticed their feature buttons were not working. After running a SIP trace, the administrator did not see any PPM Responses coming from Avaya Aura® Session Manager (SM).
After looking at how the call flow is supposed to go, the administrator looked at the SIP communication profile and saw that CM had not been administered as a sequenced application.
If CM had been added to the endpoint's SIP Communication Profile as a Sequenced Application, which step was missing in the call flow?
