Question No. 1

Describe the functionality of ARP.

AClients do not have an ARP cache and always ask for the default gateway.

BARP maps MAC addresses to switch ports.

CARP maps layer-3 IP addresses to layer-2 MAC addresses.

DARP uses multicast to build the ARP table.

Show Answer

Correct Answer: C

The Address Resolution Protocol (ARP) is used to map layer-3 IP addresses to layer-2 MAC addresses. When a device on a network wants to communicate with another device, it uses ARP to find the MAC address that corresponds to the IP address it wishes to communicate with, allowing it to construct a frame for the local network.

Question No. 2

What does a slow amber-flashing Stack-LED indicate?

AOne switch has a stacking failure.

BA port has a stacking failure Stacking mode Is not selected

CStacking mode selected

DStacking is synchronizing Please wait

Show Answer

Correct Answer: C

A slow amber-flashing Stack-LED indicates that stacking mode is selected on the switch. This means that the switch is ready to join a stack or form a new stack if no other switches are present.

Question No. 3

When performing live firmware upgrades on Aruba APs. which technology partitions all the APs based on RF neighborhood data minimizing the impact on clients?

AAruba ClientMatch

BAruba Ai insights

CAruba AirMatch

DAruba ESP

Show Answer

Correct Answer: C

Aruba AirMatch is a feature that optimizes RF Radio Frequency. RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. performance and user experience by using machine learning algorithms and historical data to dynamically adjust AP power levels, channel assignments, and channel width. AirMatch performs live firmware upgrades on Aruba APs by partitioning all the APs based on RF neighborhood data and minimizing the impact on clients. AirMatch uses a rolling upgrade process that upgrades one partition at a time while ensuring that adjacent partitions are not upgraded simultaneously.

This method allows a network technician to interact with the boot process, view boot messages, and access boot options, including the selection of different OS images or ServiceOS for recovery purposes.

Question No. 5

When measuring signal strength, dBm is commonly used and 0 dBm corresponds to 1 mW power.

What does -20 dBm correspond to?

A.-1 mW

B.01 mw

C10 mW

D1mW

Show Answer

Correct Answer: B

dBm is a unit of power that measures the ratio of a given power level to 1 mW. The formula to convert dBm to mW is: P(mW) = 1mW * 10^(P(dBm)/10). Therefore, -20 dBm corresponds to 0.01 mW, as follows: P(mW) = 1mW * 10^(-20/10) = 0.01 mW Reference: https://www.rapidtables.com/convert/power/dBm_to_mW.html

The dBm is a logarithmic unit of power relative to 1 milliwatt (mW). -20 dBm means that the signal strength is 20 decibels lower than 1 mW. In terms of mW, this is 0.01 mW. Each 10 dB decrease represents a tenfold decrease in power. Therefore, -20 dBm is 102102 or 0.01 mW.
