問題 #34
What is the purpose of the packages.conf file in Install mode on Cisco IOS XE Software supported switches?
答案:A
解題說明:
InInstall mode, thepackages.conffile plays a crucial role in the boot process of Cisco IOS XE Software. It specifies the list of software packages to be loaded and the sequence in which they should be initialized during system startup. This file ensures that all necessary components are correctly loaded, providing a modular and flexible approach to software management.
Contrary to the other options:
* Thepackages.conffile does not extract the bin file; it references already extracted packages.
* It does not contain the entire bundled image; that's characteristic of Bundle mode.
* While it resides in the flash memory, it is not a subdirectory but a configuration file.

問題 #35
Drag and drop the failures from the left onto the responsible devices in the MDS field-replaceable unit on the right.
答案:
解題說明:
Explanation:
Inability to manage or control switch functions # Supervisor module
Failure to maintain optimal temperatures # Fan module
Loss of connectivity on specific ports # Line card
Inability to establish fiber optic connections # Transceivers
Degraded internal data transfer between line cards # Fabric module
From theFLDTEC training materials, Cisco MDS switches are built for high availability and redundancy, but field technicians must know which component impacts whatfunction:
* Supervisor Module: Manages control plane functions - a failure results in loss of system-level management or redundancy.
* Fan Module: Essential for cooling - failure here leads to overheating and thermal alarms.
* Line Card: Provides connectivity - port failures or loss of interface status originate from faulty line cards.
* Transceivers (SFP/QSFP modules): Responsible for optical transmission - failure leads to fiber optic link issues.
* Fabric Module: Critical for switching between line cards - its failure leads to degraded or disrupted internal traffic paths.
These mappings help techniciansisolate the source of faultsand proceed with the correctRMA or replacementprocedure.
問題 #36
Which component of the Cisco Room system requires removal of the upper textile grille and the use of release levers during its replacement process?
答案:B
解題說明:
In Cisco Room systems such as the Room Kit Pro and similar setups, replacing thequad camerainvolves a physical disassembly process. Specifically, theupper textile grille must be removedto gain access to the internal mounting mechanism. After that,release levers are used to disengage the quad camera unitfrom its housing.
This procedure ensures secure installation while allowing relatively straightforward removal when maintenance or replacement is necessary. The codec, loudspeaker, and antenna module do not typically require this specific removal method.

問題 #37
Which protocol should be analyzed when troubleshooting call quality between IP phones?
答案:D
解題說明:
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
問題 #38
Which Cisco switch series is designed to handle the combined responsibilities of core and distribution layers in a converged architecture?
答案:A
解題說明:
TheCisco Catalyst 9000 Seriesis engineered to address the evolving needs of modern enterprise networks by integrating the functionalities of both the core and distribution layers into a unified, converged architecture.
This series offers advanced capabilities such as high-speed data forwarding, enhanced security features, and support for automation and programmability, making it suitable for scalable and efficient network designs.
The Catalyst 9000 Series includes models like the Catalyst 9500 and 9600, which are optimized for core and distribution roles, providing high throughput and reliability. These switches support advanced features like Software-Defined Access (SD-Access) and are designed to meet the demands of cloud-scale and security- focused environments.
In contrast, theMeraki MS400 Series(Option A) is tailored for cloud-managed aggregation and lacks the comprehensive feature set required for core functionalities. TheCatalyst 6500 E-Series(Option B), while historically significant, is considered a legacy platform and may not support the latest advancements in network convergence. TheCatalyst 1300 Series(Option C) is designed for small to medium-sized businesses and is not intended for core or distribution layer deployments.
