XOR

RSSI

RRM

SNR

Question # 43

for device, value In device_ip.items(): print(device)

for device in device_ip.items(): print(device)

for device in device_ip.values(): print(device)

Question # 44

Refer to the exhibit. What is achieved by this Python script?

It displays the output from show lldp neighbors into a standard output.

It reads the neighbor count from show lldp neighbors into a dictionary list.

It displays the Layer 3 neighbors from show lldp neighbors on the terminal screen.

It reads the output from show lldp neighbors into an array object.

Question # 45

Why is a Type 1 hypervisor more efficient than a Type 2 hypervisor?

Type 1 hypervisor is the only type of hypervisor that supports hardware acceleration techniques.

Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS.

Type 1 hypervisor enables other operating systems to run on it.

Type 1 hypervisor relies on the existing OS of the host machine to access CPU, memory, storage, and network resources.

Question # 46

Which network design reduces convergence time between an aggregation layer and a Layer 2 access layer in an enterprise network?

Traditional looped design that has common VLANs extended between separate access switches

Cisco SD-Access configuration between aggregation intermediate nodes and access layers

Cisco SD-Access configuration between aggregation and access-layer edge nodes

Traditional nonlooped design that has unique VLANs extended between separate access switches

Explanation:

The correct answer is D.

Cisco campus design guidance explains that a nonlooped topology with unique VLANs per access switch improves stability and convergence compared with looped Layer 2 designs. Cisco states that in a multilayer campus design, each access switch should have unique VLANs, with no Layer 2 loops and no blocked links, which improves convergence behavior. Cisco also notes that VLANs spanning multiple access switches increase flooding impact, while a nonlooped topology with localized VLANs reduces that impact.

A traditional nonlooped design reduces reliance on spanning-tree reconvergence across shared Layer 2 domains. With unique/local VLANs, failures affect a smaller fault domain and convergence is faster than in a looped design with common VLANs stretched across switches. Ciscoâ€™s campus design material specifically recommends no Layer 2 loops and unique VLANs per access switch for better operational behavior.

A. Traditional looped design that has common VLANs extended between separate access switches This increases Layer 2 complexity and spanning-tree dependency, which slows convergence compared to a nonlooped design. Cisco documents that VLANs spanning multiple access switches increase flooding impact.

B. Cisco SD-Access configuration between aggregation intermediate nodes and access layers This is not the standard way the question is framed for classic aggregation-to-Layer 2 access convergence in a traditional enterprise campus design. The question is targeting the design principle of looped vs nonlooped Layer 2 access.

C. Cisco SD-Access configuration between aggregation and access-layer edge nodes SD-Access is a different fabric architecture. The question is about reducing convergence time between aggregation and a Layer 2 access layer, which maps to the traditional campus design choice rather than SD-Access node roles.

For enterprise campus design, remember:

Looped Layer 2 + stretched/common VLANs = slower convergence and larger fault domains

Nonlooped Layer 2 + unique/local VLANs per access switch = faster convergence and better stability
