NEW QUESTION # 64
Which two cloud computing services are vendor-managed in an Infrastructure as a Service (IaaS) delivery model? (Choose two.)
Answer: A,D
Explanation:
In theInfrastructure as a Service (IaaS)model, the cloud provider is responsible for managing and maintaining the underlying infrastructure components, including:
* Networking: The cloud provider handles all aspects of network configuration, hardware, and virtual networking.
* Storage: The cloud provider supplies and manages the physical and virtual storage infrastructure required to support the consumer's data needs.
The customer is responsible for managing:
* Operating Systems
* Applications
* Data
This model offers flexibility while shifting infrastructure maintenance responsibilities to the service provider.

NEW QUESTION # 65
How must the power to a system with dual power supplies on aCisco Nexus switch be connected?
Answer: B
Explanation:
In a Cisco Nexus switch withdual power supplies, the recommended method is toconnect each power supply to a separate power source(Option C). This ensures power redundancy and fault tolerance.
If one power source fails (e.g., due to a power outage or circuit failure), the switch can continue operating uninterrupted using the second power source. Connecting both to a single source (Option D) defeats the purpose of redundancy.

NEW QUESTION # 66
Why is a Cisco Nexus switch typically deployed in a network?
Answer: C
Explanation:
Cisco Nexus switches are specifically designed for deployment in data centers, where they provide high-performance, low-latency switching to support modern workloads, virtualization, and cloud computing environments.
Nexus switches operate using NX-OS, a purpose-built operating system optimized for data center needs. These switches support technologies like virtual port channels (vPC), FabricPath, and Application Centric Infrastructure (ACI), which are essential for scalable and highly available data center networks.
They are not typically used in branch offices, as wireless access points, or as edge routers.
NEW QUESTION # 67
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.)
Answer: B,C
Explanation:
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.

NEW QUESTION # 68
Which protocol should be analyzed when troubleshooting call quality between IP phones?
Answer: C
Explanation:
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
