QUESTION: 25

What is one practice that can help you to maintain a digital chain or custody In your network?

Enable packet capturing on Instant AP or Moodily Controller (MC) datepath on an ongoing basis
Enable packet capturing on Instant AP or Mobility Controller (MC) control path on an ongoing basis.
Ensure that all network infrastructure devices receive a valid clock using authenticated NTP
Ensure that all network Infrastructure devices use RADIUS rather than TACACS+ to authenticate managers

Answer(s): C

Explanation:

To maintain a digital chain of custody in a network, a crucial practice is to ensure that all network infrastructure devices receive a valid clock using authenticated Network Time Protocol (NTP). Accurate and synchronized time stamps are essential for creating reliable and legally defensible logs. Authenticated NTP ensures that the time being set on devices is accurate and that the time source is verified, which is necessary for correlating logs from different devices and for forensic analysis.

QUESTION: 26

What is one of the roles of the network access server (NAS) in the AAA framewonx?

It authenticates legitimate users and uses policies to determine which resources each user is allowed to access.
It negotiates with each user's device to determine which EAP method is used for authentication
It enforces access to network services and sends accounting information to the AAA server
It determines which resources authenticated users are allowed to access and monitors each users session

Answer(s): C

Explanation:

In the AAA (Authentication, Authorization, and Accounting) framework, the role of the Network Access Server (NAS) is to act as a gateway that enforces access to network services and sends accounting information to the AAA server. The NAS initially requests authentication information from the user and then passes that information to the AAA server. It also enforces the access policies as provided by the AAA server after authentication and provides accounting data to the AAA server based on user activity.

QUESTION: 27

What is a use case for tunneling traffic between an Aruba switch and an AruDa Mobility Controller (MC)?

applying firewall policies and deep packet inspection to wired clients
enhancing the security of communications from the access layer to the core with data encryption
securing the network infrastructure control plane by creating a virtual out-of-band-management network
simplifying network infrastructure management by using the MC to push configurations to the switches

Answer(s): C

Explanation:

Tunneling traffic between an Aruba switch and an Aruba Mobility Controller (MC) allows for the centralized application of firewall policies and deep packet inspection to wired clients. By directing traffic through the MC, network administrators can implement a consistent set of security policies across both wired and wireless segments of the network, enhancing overall network security posture.

Reference:

Aruba Networks documentation details the use cases for tunneling traffic to an MC, including the application of security and access controls on network traffic.

QUESTION: 28

Refer to the exhibit.

A diem is connected to an ArubaOS Mobility Controller. The exhibit snows all Tour firewall rules that apply to this diem
What correctly describes how the controller treats HTTPS packets to these two IP addresses, both of which are on the other side of the firewall
10.1 10.10
203.0.13.5

It drops both of the packets
It permits the packet to 10.1.10.10 and drops the packet to 203 0.13.5
it permits both of the packets
It drops the packet to 10.1.10.10 and permits the packet to 203.0.13.5.

Answer(s): B

Explanation:

Referring to the exhibit, the ArubaOS Mobility Controller treats HTTPS packets based on the firewall rules applied to the client. The rule that allows svc-https service for destination IP range 10.1.0.0 255.255.0.0 would permit an HTTPS packet to 10.1.10.10 since this IP address falls within the specified range. There are no rules shown that would allow traffic to the IP address 203.0.13.5;

hence, the packet to this address would be dropped.

QUESTION: 29

You have detected a Rogue AP using the Security Dashboard Which two actions should you take in responding to this event? (Select two)

There is no need to locale the AP If you manually contain It.
This is a serious security event, so you should always contain the AP immediately regardless of your company's specific policies.
You should receive permission before containing an AP. as this action could have legal Implications.
For forensic purposes, you should copy out logs with relevant information, such as the time mat the AP was detected and the AP's MAC address.
There is no need to locate the AP If the Aruba solution is properly configured to automatically contain it.

Answer(s): C,D

Explanation:

When responding to the detection of a Rogue AP, it's important to consider legal implications and to gather forensic evidence:
You should receive permission before containing an AP (Option C), as containing it could disrupt service and may have legal implications, especially if the AP is on a network that the organization does not own.
For forensic purposes, it is essential to document the event by copying out logs with relevant information, such as the time the AP was detected and the AP's MAC address (Option D). This information could be crucial if legal action is taken or if a detailed analysis of the security breach is required.
Automatically containing an AP without consideration for the context (Options A and E) can be problematic, as it might inadvertently interfere with neighboring networks and cause legal issues. Immediate containment without consideration of company policy (Option B) could also violate established incident response procedures.

QUESTION: 30

What is a benefit of Protected Management Frames (PMF). sometimes called Management Frame

Protection (MFP)?

PMF helps to protect APs and MCs from unauthorized management access by hackers.
PMF ensures trial traffic between APs and Mobility Controllers (MCs) is encrypted.
PMF prevents hackers from capturing the traffic between APs and Mobility Controllers.
PMF protects clients from DoS attacks based on forged de-authentication frames

Answer(s): D

Explanation:

Protected Management Frames (PMF), also known as Management Frame Protection (MFP), is designed to protect clients from denial-of-service (DoS) attacks that involve forged de-authentication and disassociation frames. These attacks can disconnect legitimate clients from the network. PMF provides a way to authenticate these management frames, ensuring that they are not forged, thus enhancing the security of the wireless network.

QUESTION: 31

Refer to the exhibit.

You need to ensure that only management stations in subnet 192.168.1.0/24 can access the ArubaOS-Switches' CLI. Web Ul. and REST interfaces The company also wants to let managers use these stations to access other parts of the network What should you do?

Establish a Control Plane Policing class that selects traffic from 192.168 1.0/24.
Specify 192.168.1.0.255.255.255.0 as authorized IP manager address
Configure the switch to listen for these protocols on OOBM only.
Specify vlan 100 as the management vlan for the switches.

Answer(s): B

Explanation:

To ensure that only management stations in the subnet 192.168.1.0/24 can access the ArubaOS- Switches' Command Line Interface (CLI), Web UI, and REST interfaces, while also allowing managers to access other parts of the network, you should specify 192.168.1.0 255.255.255.0 as the authorized manager IP address on the switches. This configuration will restrict access to the switch management interfaces to devices within the specified IP address range, effectively creating a management access list.

QUESTION: 32

What is a benefit of Opportunistic Wireless Encryption (OWE)?

It allows both WPA2-capabie and WPA3-capable clients to authenticate to the same WPA-Personal WLAN
It offers more control over who can connect to the wireless network when compared with WPA2- Personal
It allows anyone lo connect, but provides better protection against eavesdropping than a traditional open network
It provides protection for wireless clients against both honeypot APs and man-in-the-middle (MUM) attacks

Answer(s): C

Explanation:

The benefit of Opportunistic Wireless Encryption (OWE) is that it allows anyone to connect, but it provides better protection against eavesdropping than a traditional open network. OWE is a type of wireless security specified in the WPA3 standard that offers encrypted communication without the complexity of a full authentication process, thereby securing data on networks that would otherwise be open and unencrypted.
