QUESTION: 13

What is the correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1?

ip-route 10.2.10.0/24 172.16.1.1
ip route 10.2.10.0.255.255.255.0 172.16.1.1 description aruba
ip route 10.2.10.0/24.172.16.11
ip route-static 10.2 10.0.255.255.255.0 172.16.1.1

Answer(s): A

Explanation:

The correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1 is ip-route 10.2.10.0/24 172.16.1.1 . This command specifies the destination network address (10.2.10.0) and prefix length (/24) and the next-hop address (172.16.1 .1) for reaching that network from the switch. The other commands are either incorrect syntax or incorrect parameters for adding a static route.

Reference:

https://www.arubanetworks.com/techdocs/AOS-CX_10_04/NOSCG/Content/cx-noscg/ip-routing/static-routes.htm To add a static route in network devices, including Aruba switches, the correct command format generally includes the destination network, subnet mask (or CIDR notation for the mask), and the next-hop IP address. The command "ip route 10.2.10.0/24 172.16.1.1" correctly specifies the destination network "10.2.10.0" with a class C subnet mask indicated by "/24", and "172.16.1.1" as the next-hop IP address. This command is succinct and follows the standard syntax for adding a static route in many network operating systems, including ArubaOS-CX. The other options either have incorrect syntax or include additional unnecessary parameters that are not typically part of the standard command to add a static route.

QUESTION: 14

You need to configure wireless access for several classes of loT devices, some of which operate only with 802 11b. Each class must have a unique PSK and will require a different security policy applied as a role There will be 15-20 different classes of devices and performance should be optimized Which option fulfills these requirements''

Single SSID with MPSK for each loT class using 5 GHz and 6 GHz bands
Single SSID with MPSK for each loT class using 2.4GHz and 5 GHz bands
Individual SSIDs with unique PSK for each loT class, using 5GHz and 6 GHz bands
Individual SSIDs with unique PSK for each loT class, using 2.4GHZ and 5GHz band

Answer(s): B

Explanation:

For configuring wireless access for multiple classes of IoT devices with varying security requirements, using a single SSID with Multiple Pre-Shared Keys (MPSK) is an efficient solution. MPSK allows different devices or groups of devices to connect to the same SSID but with unique PSKs, facilitating unique security policies for each class. Given that some IoT devices only support 802.11b, which operates in the 2.4GHz band, it is essential to include the 2.4GHz band in the configuration. The 5GHz band should also be included to support devices capable of operating in that band and to optimize network performance. The 6GHz band (option A) is not suitable since 802.11b devices are not compatible with it. Individual SSIDs for each IoT class (options C and D) would unnecessarily complicate network management and SSID overhead.

QUESTION: 15

The noise floor measures 000000001 milliwatts, and the receiver's signal strength is -65dBm.
What is the Signal to Noise Ratio?

35 dBm
15 dBm
45 dBm
25 dBm

Answer(s): D

Explanation:

The signal to noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels (dB). A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover. To calculate the SNR in dB, we can use the following formula:
SNR (dB) = Signal power (dBm) - Noise power (dBm)
In this question, we are given that the noise floor measures -90 dBm (0.000000001 milliwatts) and the receiver's signal strength is -65 dBm (0.000316 milliwatts). Therefore, we can plug these values into the formula and get:
SNR (dB) = -65 dBm - (-90 dBm) SNR (dB) = -65 dBm + 90 dBm SNR (dB) = 25 dBm Therefore, the correct answer is that the SNR is 25 dBm.

DRAG DROP (Drag and Drop is not supported)
Match the switching technology with the appropriate use case.

See Explanation section for answer.

Answer(s): A

Explanation:

USE CASE: a) Controls the dynamic addition and removal of ports to groups
Technology: 3) LACP USE CASE: b) Tags Ethernet frames with an additional VLAN header Technology: 1) 802.1Q USE CASE: c) Used to authenticate EAP-Capable client on a switch port
Technology: 2) 802.1X USE CASE: d) Used to identify a voice VLAN to an IP phone Technology: 4) LLDP The following table summarizes the switching technologies and their use cases:
Technology Use case

802.1Q is a standard that defines how to create and manage virtual LANs (VLANs) on a network. VLANs allow network administrators to logically segment a network into different broadcast domains, improving security, performance, and manageability. 802.1Q tags Ethernet frames with an additional VLAN header that
1) 802.1Q contains a VLAN identifier (VID), which indicates which VLAN the frame belongs to 1.802.1X is a standard that defines how to provide port-based network access control (PNAC) on a network. PNAC allows network administrators to authenticate and authorize devices before granting them access to network resources. 802.1X uses the Extensible Authentication Protocol (EAP) to exchange authentication messages between a supplicant (a device that wants to access the network), an authenticator (a device that controls access to the network, such as a switch), and an authentication server (a device that verifies the 2) 802.1X credentials of the supplicant, such as a RADIUS server)
2) LACP stands for Link Aggregation Control Protocol, which is part of the IEEE 802.3ad standard that defines how to bundle multiple physical links into a single logical link, also known as a link aggregation group (LAG) or an EtherChannel. LAGs provide increased bandwidth, load balancing, and redundancy for network connections. LACP controls the dynamic addition and removal of ports to groups, ensuring that only ports
3) LACP with compatible configurations can form a LAG.

LLDP stands for Link Layer Discovery Protocol, which is part of the IEEE 802.1AB standard that defines how to discover and advertise information about neighboring devices on a network. LLDP operates at Layer 2 of the OSI model and uses TLVs (type-length-value) to exchange information such as device name, port number, VLAN ID, capabilities, and power requirements. LLDP can be used to identify a voice VLAN to an IP phone by
4) LLDP sending a TLV that contains the voice VLAN ID and priority.
