NEW QUESTION # 20
How must the power to a system with dual power supplies on aCisco Nexus switch be connected?
Answer: A
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 # 21
What is the primary role of a switch in a local area network?
Answer: D
Explanation:
In a local area network (LAN), the primary function of a switch is to operate at Layer 2 (Data Link Layer) of the OSI model. Switches use MAC addresses to forward frames to the appropriate destination ports. This targeted forwarding mechanism divides the network into separate collision domains for each switch port. By isolating collision domains, switches significantly reduce the chance of collisions, enhancing the performance and efficiency of the network.
Unlike hubs, which forward all traffic to all ports (thus creating a single collision domain), switches intelligently forward only the necessary traffic to the correct port. This capability allows multiple simultaneous conversations on different switch ports without interference.
Routers, which operate at Layer 3 (Network Layer), are used to route packets between different networks, not within the same LAN. Wireless connectivity is provided by wireless access points (WAPs), not switches. Encryption is typically handled by security protocols or devices such as firewalls and not by switches directly.
NEW QUESTION # 22
Which protocol should be analyzed when troubleshooting call quality between IP phones?
Answer: C
Explanation:
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.
NEW QUESTION # 23
Which step must be taken to minimize data traffic impact when replacing a fabric interconnect?
Answer: B
Explanation:
When replacing a fabric interconnect in a Cisco Unified Computing System (UCS), the recommended procedure to minimize traffic disruption is to use the fabric evacuation procedure on the subordinate fabric interconnect. This ensures that traffic is redirected to the other (active) fabric interconnect, allowing the system to maintain connectivity while one interconnect is replaced.
High availability should remain enabled to preserve redundancy.
Powering down both interconnects would cause a complete outage.
Disconnecting cables without graceful evacuation can result in traffic loss.
NEW QUESTION # 24
Which scenario would result in a speed mismatch when configuring Ethernet devices with different speed settings?
Answer: A
Explanation:
A speed mismatch occurs when two connected Ethernet devices are configured to operate at different speeds.
In scenario A, one device is manually set to 1 Gbps, while the other is set to 100 Mbps. Since both ends are hard-coded to different speeds, they cannot successfully negotiate a common speed, leading to a mismatch and resulting in a failed or unstable link.
In contrast, scenario B, where both ends are manually set to the same speed, ensures compatibility and stable communication. Scenario C can lead to a duplex mismatch rather than a speed mismatch; the auto-negotiating end may default to half-duplex if it cannot determine the duplex setting of the manually configured end.
Scenario D is less common; if auto-negotiation fails, devices may revert to their lowest common speed, but this typically results in reduced performance rather than a complete mismatch.
