質問 # 10
Which protocol should be analyzed when troubleshooting call quality between IP phones?
正解:B
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

Drag and drop the safety actions that must be taken prior to beginning work into order on the right for working with electrical equipment.
正解:
解説:
Explanation:
In theFLDTEC course, underSafety and ESD Procedures, Cisco outlines the following safety workflow before working on any network hardware:
* Locate Emergency Power-Off Switch: Identifying how to cut power quickly is essential in case of an electrical fault or emergency.
* Disconnect Power: Always ensure the power source is turned off and disconnected before handling any components.
* Verify with Multimeter: Use a multimeter to confirm that no voltage is present before proceeding.
* Connect ESD Strap: Once confirmed safe, attach your ESD strap to a grounded point to prevent electrostatic damage to sensitive components.
Following this process is critical not only forpersonal safetybut also forequipment protection, especially duringhardware installation, maintenance, or RMA replacements.
質問 # 12
Why is it important to verify the update status after the initial upgrade process when upgrading firmware on a Cisco UCS C-Series server using the Host UpgradeUtility?
正解:D
解説:
After upgrading the firmware on aCisco UCS C-Series serverusing theHost Upgrade Utility (HUU), it is critical toverify the update statusto ensure thatall targeted components(such as BIOS, CIMC, and RAID controller firmware) have beensuccessfully updated.
Firmware upgrades often involve multiple subsystems, and partial or failed updates can result in inconsistencies or even device instability. Verifying the update status allows the technician to identify any missed components and perform corrective actions if necessary.
Options like generating compliance reports, third-party application checks, or license activations are not the primary reasons for this verification step in the HUU process.

質問 # 13
What is the purpose of the chassis in a blade server environment?
正解:B
解説:
In ablade server environment, thechassisserves as the enclosure thathouses multiple blade servers. It provides shared power, cooling, and connectivity resources. Blade servers are compact server modules that insert into the chassis, and the shared infrastructure makes the entire system efficient in space, power, and management.
The chassis does not act as a switch or storage array itself but provides interconnects and sometimes integrated networking components.

質問 # 14
What is the function of an access layer device?
正解:B
解説:
In the hierarchical network design model, theaccess layeris the first layer and serves as the entry point for end- user devices to connect to the network. This layer connects user devices such as PCs, IP phones, wireless access points, printers, and scanners to the network. It facilitates the initial connection between end-user devices and the network infrastructure. The access layer also enforces security policies and provides services such as VLAN membership, port security, and Quality of Service (QoS).
Options A, C, and D refer to functions typically associated with the core or distribution layers, or with WAN connectivity, rather than the access layer.
