質問 # 42
Which protocol should be analyzed when troubleshooting call quality between IP phones?
正解:C
解説:
When addressing call quality issues between IP phones, theReal-time Transport Protocol (RTP)is the primary protocol to analyze. RTP is responsible for the actual transmission of voice data during a call, and its performance directly impacts call quality.
Key factors affecting RTP and, consequently, call quality include:
* Packet Loss:Missing packets can lead to audio gaps.
* Jitter:Variations in packet arrival times can cause choppy audio.
* Latency:Delays in packet delivery can result in noticeable lag.
Analyzing RTP streams allows technicians to identify these issues and implement appropriate Quality of Service (QoS) measures to mitigate them.
Incontrast:
* SIP (Session Initiation Protocol):Handles call setup, modification, and teardown but not the media stream.
* SCCP (Skinny Client Control Protocol):A Cisco proprietary protocol for signaling, not media transport.
* H.323:An older protocolsuite for multimedia communication, encompassing both signaling and media, but less commonly used in modern IP telephony.Reference:Supporting Cisco Devices for Field Technicians (FLDTEC) - Troubleshooting Methodologie

質問 # 44
What is the primary purpose of backing up the endpoint configuration prior to replacing the device?
正解:C
解説:
Backing up the configuration of a network device before replacement is a critical step to ensure business continuity and minimize downtime. The primary purpose of this backup is torestore the existing settings onto the new device, ensuring that it operates identically to the one being replaced.
This process includes preserving interface configurations, routing protocols, access control lists, and other essential parameters. By restoring the backed-up configuration to the new device, network administrators can quickly reintegrate it into the network infrastructure without the need for manual reconfiguration, thereby reducing the risk of errors and service disruptions.
Options A, B, and C do not align with the primary objective of configuration backups in the context of device replacement.

質問 # 46
Which two configuration parameters are most critical to ensure optimal performance when configuring a network port for a newly installed IP phone in an enterprise environment? (Choose two.)
正解:B、D
解説:
When configuring a network port for a newly installed IP phone, two critical parameters to ensure optimal performance are:
VLAN Assignment: Assigning the correct VLANs is essential for segregating voice and data traffic. Typically, a separate voice VLAN is configured to prioritize voice traffic and enhance security.
Power over Ethernet (PoE): PoE allows the switch to supply power to the IP phone over the same Ethernet cable used for data transmission. This eliminates the need for separate power supplies and simplifies installation.
While QoS classification (Option E) is important for prioritizing voice traffic, it is typically configured at a broader network level. Link aggregation (Option B) and Spanning Tree Protocol (Option C) are more relevant to network redundancy and loop prevention, respectively, and are not directly critical for the initial configuration of an IP phone port.
