What is a core component of a modern telecom platform responsible for converting media streams between different network technologies?
Marketing Module
Billing Dashboard
Media Gateway
CRM System
A Media Gateway converts media streams between different network technologies, such as TDM and IP. It is essential for interoperability in modern telecom platforms.
Which protocol is commonly used for signaling in Voice over IP (VoIP) communications?
SIP
SMTP
FTP
HTTP
Session Initiation Protocol (SIP) is the industry standard for setting up, managing, and terminating VoIP sessions. Other protocols like FTP and SMTP are not used for VoIP signaling.
Which performance metric measures the average time it takes for a call to be answered?
Answer Seizure Ratio (ASR)
Requests Per Second (RPS)
Mean Opinion Score (MOS)
Average Speed of Answer (ASA)
The Average Speed of Answer (ASA) measures the average time between a call arriving and it being answered. ASR measures successful answers, MOS measures quality, and RPS is a web metric.
Which API architecture style is widely adopted for telecom service integrations due to its lightweight nature?
RESTful API
SNMP
GraphQL
SOAP API
RESTful APIs use standard HTTP methods and lightweight data formats like JSON, making them popular for telecom integrations. SOAP is heavier and SNMP is for network management.
What is the primary purpose of authentication mechanisms in telecom APIs?
To compress API payloads
To restrict unauthorized access to services
To ensure high bandwidth allocation
To improve call audio quality
Authentication ensures that only authorized users or systems can access telecom APIs. Bandwidth, compression, and audio quality are unrelated to API authentication.
Which metric best indicates a telecom platform's ability to handle increasing load without performance degradation?
Mean Opinion Score
Network Latency
Call Setup Rate (CSR)
Packet Loss Rate
Call Setup Rate measures how many calls the system can establish per unit time, reflecting scalability. Other metrics indicate quality or delay but not raw capacity.
When facing unexpectedly high call setup latency, what is the most appropriate first troubleshooting step?
Check the network path and perform a traceroute
Restart the core database server
Increase CPU allocation on media servers
Upgrade the router firmware immediately
High latency often stems from network issues, so traceroute helps identify hops causing delays. Database or firmware changes are secondary without network diagnostics.
Which protocol is specifically designed for exchanging SMS messages between applications and telecom networks?
SMTP
SMPP
FTP
HTTP
Short Message Peer-to-Peer (SMPP) protocol is the de facto standard for sending SMS between external applications and telecom message centers. HTTP and SMTP are not optimized for SMS.
Which security practice helps prevent unauthorized access to telecom APIs?
Store credentials in clear text
Allow open CORS policies
Disable TLS encryption
Implement API key validation
API key validation ensures that only clients with valid credentials can access services. Disabling encryption and open policies weaken security, and clear-text storage is insecure.
In telecom performance testing, which measurement represents the number of simultaneous active calls a system can support?
Packet Delay Variation
Concurrent Sessions
Mean Opinion Score
Throughput in Mbps
Concurrent Sessions measures how many active calls the platform can handle at once. Throughput in Mbps relates to bandwidth, MOS to quality, and delay variation to jitter.
Which DNS response code indicates that a queried domain name does not exist?
200 OK
500 Internal Server Error
404 Not Found
NXDOMAIN
NXDOMAIN is the DNS-specific response indicating a non-existent domain. HTTP codes like 404 do not apply to DNS queries.
For achieving high availability in a telecom system, which architecture is most effective?
Standalone server without redundancy
Peer-to-peer end-user connections
Load-balanced cluster of application servers
Single monolithic server
A load-balanced cluster provides redundancy and failover, ensuring high availability. A single server or non-redundant setups introduce single points of failure.
In HTTP-based telecom APIs, which status code signifies a successful request?
400 Bad Request
200 OK
500 Internal Server Error
302 Found
HTTP 200 OK indicates that a request was successfully processed by the server. Client and server error codes indicate failures.
What does a Service Level Agreement (SLA) primarily define in a telecom context?
Required performance and availability targets
Marketing budgets
Hardware vendor catalogs
User interface layouts
An SLA specifies the expected performance, uptime, and support metrics between provider and customer. It does not cover budgets or UI designs.
Which data protection regulation is most relevant for handling personal user data in European telecom operations?
SOX
PCI DSS
GDPR
HIPAA
The General Data Protection Regulation (GDPR) governs personal data privacy in the EU. HIPAA covers healthcare data in the US; PCI DSS covers payment cards.
During a SIP INVITE flooding attack, which mitigation strategy is most effective to maintain platform stability?
Disable SIP ALG on routers
Implement rate limiting on incoming SIP requests
Increase database cache size
Migrate to UDP for SIP transport
Rate limiting throttles excessive SIP INVITE messages, protecting resources and ensuring stability. Other measures do not address the flood attack directly.
To maintain end-to-end Quality of Service in IP networks, which header field is used to mark packet priority?
TCP port number
VLAN ID in the Ethernet frame
DSCP field in the IP header
MPLS label stack
Differentiated Services Code Point (DSCP) in the IP header marks packet priority for QoS enforcement. VLAN IDs and MPLS labels serve other functions, and port numbers are not QoS markers.
Which set of HTTP methods are all idempotent according to RESTful API standards?
POST, PATCH, OPTIONS
POST, PUT, DELETE
GET, POST, PATCH
GET, PUT, DELETE
GET, PUT, and DELETE are idempotent methods that produce the same effect when repeated. POST and PATCH are not guaranteed idempotent in RESTful APIs.
For secure media transmission in telecom, which protocol is used to encrypt real-time voice streams?
SRTP
S/MIME
TLS
SFTP
Secure Real-Time Transport Protocol (SRTP) encrypts and authenticates RTP media streams for voice and video. TLS secures signaling, while S/MIME and SFTP address different use cases.
Which database replication model ensures synchronous consistency across nodes in a horizontally scaled telecom platform?
Sharded asynchronous model
Master-slave synchronous replication
Multi-master asynchronous replication
Peer-to-peer eventual consistency
Master-slave synchronous replication writes data to both primary and secondary nodes before confirming success, ensuring strong consistency. Asynchronous or eventual models may lag and lose atomic consistency.
