- Question 24Single Choice
Which TCP port is the default for encrypted SIP signaling in Avaya Aura?
- A5060
- B5061Correct answer
- C8443
- D1720
Why this is the answer
SIP over TLS uses port 5061. Port 5060 is for unencrypted SIP (UDP/TCP), 8443 is for System Manager web, 1720 is for H.323.
- Question 25Multiple Select
Which two security controls are classified as preventative in nature?
- ARole-Based Access Control (RBAC)Correct answer
- BAudit logs and log monitoring
- CFirewall rules restricting trafficCorrect answer
- DDisaster recovery backups
Why this is the answer
RBAC and firewall rules are preventative – they block actions. Audit logs are detective; backups are corrective.
- Question 26Interactive
Examine the SDP fragment from a SIP message. What required attribute is missing for SRTP to work?
- AAn 'a=crypto' lineCorrect answer
- BA 'm=audio' line
- CThe 'a=rtpmap' attribute
- DThe 'c=IN IP4' line
Why this is the answer
SRTP requires a 'crypto' attribute in the SDP to specify encryption keys and algorithms. Without it, the call falls back to plain RTP.
- Question 27Single Choice
Which System Manager role should be assigned to an auditor who only needs to view logs and system status?
