Which component is used by the Aruba Network Analytics Engine (NAE)?

  1. JSON-based scripts
  2. Lisp-based agents
  3. Ruby-based scripts
  4. Current State Database

Answer(s): A

Explanation:

The component that is used by the Aruba Network Analytics Engine (NAE) is D. Current State Database.
The Current State Database is a database that stores the configuration and state information of the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The NAE can access this database through the AOS-CX REST API and monitor the values of any data point using monitors. The NAE can also track the history of the values in a time-series database and correlate them with network events or configuration changes. The Current State Database provides NAE with direct visibility into the entire current state of the device, which enables intelligent troubleshooting and automation of network tasks.
The other options are incorrect because:
A) JSON-based scripts: JSON is a data format that is used to exchange information between applications. It is not a scripting language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language.

B) Lisp-based agents: Lisp is a family of programming languages that are mainly used for artificial intelligence and functional programming. It is not a language that can be used by NAE. NAE agents are instances of scripts that run on the switch and collect relevant network information and trigger alerts or actions.
C) Ruby-based scripts: Ruby is a general-purpose programming language that is known for its expressiveness and elegance. It is not a language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language.



You need to have different routing-table requirements with Aruba CX 6300 VSF configuration

Assuming the correct layer-2 VLAN already exists how would you create a new OSPF configuration for a separate routing table?

  1. Create a new OSPF area, and attach VRF name.
  2. Create a new OSPF process ID with vrf name.
  3. Attach a new OSFP process ID with a custom routing table
  4. Attach OSPF process ID in the VRF configuration.

Answer(s): B

Explanation:

To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF.

With the Aruba CX switch configuration, what is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation?

  1. Active Gateway
  2. Active-Active VRRP
  3. SVI with vsx-sync
  4. VRRP

Answer(s): A

Explanation:

Active Gateway is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation. Active Gateway is a feature that allows both VSX peers to act as active gateways for different subnets, eliminating the need for VRRP or other first-hop redundancy protocols. Active Gateway also provides fast failover and load balancing for L3 traffic across the VSX peers. The other options are incorrect because they are either not recommended or not supported by Aruba CX VSX.

You are deploying a bonded 40 MHz wide channel What is the difference in the noise floor perceived by a client using this bonded channel as compared to an unbonded 20MHz wide channel?

  1. 2dB
  2. 3dB
  3. 8dB
  4. 4dB

Answer(s): B

Explanation:

The difference in the noise floor perceived by a client using a bonded 40 MHz wide channel as compared to an unbonded 20 MHz wide channel is 3 dB. The noise floor is the level of background noise in a given frequency band.
When two adjacent channels are bonded, the noise floor increases by 3 dB because the bandwidth is doubled and more noise is captured. The other options are incorrect because they do not reflect the correct relationship between bandwidth and noise floor.
