HPE7-A02 Dumps With Exact Questions and Answers

Running periodic subnet scans on devices from HPE Aruba Networking ClearPass Policy Manager (CPPM) can be used to gather DHCP fingerprints, which help determine a client's device category and operating system. DHCP fingerprints are unique patterns in DHCP request packets that provide valuable information about the device type and OS, assisting in device profiling and policy enforcement.

1.DHCP Fingerprinting: This technique captures specific details from DHCP packets to identify the type and operating system of a device.

2.Device Profiling: By running subnet scans, CPPM can continuously update its device database with accurate profiles, ensuring that policies are applied correctly based on the device type.

3.Network Visibility: Regular scanning helps maintain up-to-date visibility of all devices on the network, improving security and management.

Why MD5 Authentication on Lag 1 is Preferred:

Lag 1 is the primary link between Switch-2 and Switch-1, both of which are Layer 3 switches running OSPF.

By enabling MD5 authentication, OSPF routers exchange authenticated packets, preventing unauthorized or rogue OSPF routers from forming adjacencies or injecting routes.

MD5 is a secure authentication method and ensures the integrity and authenticity of OSPF communications.

Other Options Analysis:

A. Configure OSPF authentication on VLANs 10-19 in password mode: While configuring authentication on VLAN interfaces could secure VLAN-specific OSPF traffic, it is less effective because the main threat of rogue OSPF comes from unauthorized L3 devices connected via the backbone (Lag 1).

C. Disable OSPF entirely on VLANs 10-19: Disabling OSPF on these VLANs is not a preferred solution because OSPF is needed to route traffic in this design.

D. Configure passive-interface as the OSPF default and disable OSPF passive on Lag 1: While passive interfaces prevent OSPF from forming adjacencies, it does not directly prevent rogue routers. Passive mode only limits OSPF advertisements on specific interfaces.

When using OpenSSL to obtain a certificate signed by a Certification Authority (CA), you should submit the Certificate Signing Request (CSR) file, which is file1.pem, to the CA. The CSR contains the information about the entity requesting the certificate and the public key, but not the private key, which is in file2.pem. The CA uses the information in the CSR to create and sign the certificate.

1.CSR Submission: The CSR (file1.pem) includes the public key and the entity information required by the CA to issue a certificate.

2.Private Key Security: The private key (file2.pem) should never be sent to the CA or shared; it remains securely stored on the requestor’s server.

3.Certificate Issuance: After the CA signs the CSR, the resulting certificate can be used with the private key to establish secure communications.
