Cisco Supporting Cisco Devices for Field Technicians 認定 800-150 試験問題 (Q78-Q83):

質問 # 78
What is the primary advantage of installing and deploying Cisco UCS E-Series servers in branch office routers?

A. To serve as a backup storage system for the main data center
B. To provide local compute power for edge applications
C. To increase the packet forwarding capacity of the router
D. To enhance the wireless capabilities of the router

正解：B

解説：
Cisco UCS E-Series servers are integrated, blade-style compute modules that can be installed inside Cisco ISR (Integrated Services Routers). Their primary advantage is to provide local compute resources in branch offices without needing a full data center environment.
This enables:
Hosting of virtual machines or applications locally
Reduced latency for edge computing
Lowered dependency on central data center resources
These servers are ideal for running branch-office workloads, virtualization, or edge analytics, allowing enterprises to deploy scalable compute capabilities closer to the data source.

質問 # 79
Refer to the exhibit.

Refer to the exhibit. Which CLI show command identifies the serial number on a router?

A. show inventory
B. show version
C. show idprom
D. show platform

正解：A

解説：
The show inventory command is used on Cisco devices to display detailed information about the hardware components installed, including:
Product Identifier (PID)
Serial Number (SN)
Description of the component
In the exhibit, the output clearly shows:
NAME: "Chassis", DESCR: "Cisco ISR4451-X/K9"
PID: ISR4451-X/K9, VID: V01, SN: FCW2134L0SH
This confirms that show inventory is the correct command to retrieve the serial number and hardware inventory details.
show version provides some system information and sometimes includes serial numbers, but it's not as reliable or detailed for component-level hardware info.
show idprom is not commonly used and not supported on all platforms.
show platform provides platform-specific info but not typically the serial number.

質問 # 80
What does OIR stand for in the context of Cisco ASR component replacement?

A. Online Insertion and Removal
B. Offline Installation and Reboot
C. Optical Interface Routing
D. Operational Interface Redundancy

正解：A

解説：
Online Insertion and Removal (OIR) is a feature supported by Cisco ASR routers that allows for the insertion and removal of hardware components, such as line cards and modules, while the router is operating. This capability enables maintenance and upgrades without the need to power down the system, thus minimizing network downtime.
Key aspects of OIR include:
Seamless Operation: OIR allows for hardware changes without interrupting the router's operation.
Preservation of Routing Information: The router maintains all routing information and active sessions during the insertion or removal process.
Administrative Shutdown: While not mandatory, it is recommended to administratively shut down the interfaces associated with the component being removed to ensure a graceful transition.
This feature is particularly beneficial in high-availability environments where maintaining continuous network service is critical.

質問 # 81
Which protocol should be analyzed when troubleshooting call quality between IP phones?

A. SCCP
B. 323: An older protocol suite 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
C. SIP
D. H.323
E. RTP

正解：E

解説：
When addressing call quality issues between IP phones, the Real-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.
In contrast:
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.

質問 # 82
Which step must be performed immediately after powering off the device when replacing a Cisco chassis?

A. Label and remove all I/O cables.
B. Remove the chassis.
C. Back up the device configuration.
D. Remove the chassis ground.

正解：A

解説：
After powering off a Cisco device in preparation for chassis replacement, theimmediate next stepis tolabel and remove all I/O cables. This step is crucial to ensure that all connections can be accurately restored after the new chassis is installed.
Proper labeling prevents confusion and potential misconfigurations during reassembly. Only after all cables are safely disconnected should you proceed to remove the chassis ground and then the chassis itself.
