HPE7-A01 Exam - Topic 4 Question 20 Discussion

Actual exam question for HP's HPE7-A01 exam

Question #: 20
Topic #: 4

A customer is looking Tor a wireless authentication solution for all of their loT devices that meet the following requirements

- The wireless traffic between the IoT devices and the Access Points must be encrypted

- Unique passphrase per device

- Use fingerprint information to perform role-based access

Which solutions will address the customer's requirements? (Select two.)

AMPSK and an internal RADIUS server

BMPSK Local with MAC Authentication

CClearPass Policy Manager

DMPSK Local with EAP-TLS

ELocal User Derivation Rules

Show Suggested Answer

Suggested Answer: C

The reason is that the linkup delay timer is a feature that delays bringing downstream VSX links up, following a VSX device reboot or an ISL flap. The linkup delay timer has two phases: initial synchronization phase and link-up delay phase.

The initial synchronization phase is the download phase where the rebooted node learns all the LACP+MAC+ARP+STP database entries from its VSX peer through ISLP. The initial synchronization timer, which is not configurable, is the required time to download the database information from the peer.

The link-up delay phase is the duration for installing the downloaded entries to the ASIC, establishing router adjacencies with core nodes and learning upstream routes. The link-up delay timer default value is 180 seconds. Depending on the network size, ARP/routing tables size, you might be required to set the timer to a higher value (maximum 600 seconds).

When both VSX devices reboot, the link-up delay timer is not used.

Therefore, by configuring the linkup delay timer to include LAGs 101 and 102, which are part of the same VSX device as LAG 201, you can ensure that both devices have enough time to synchronize their databases and form routing adjacencies before bringing down their downstream links.

EAP-TLS sounds complicated for IoT devices, right?

Wait, unique passphrase per device? That's a lot to manage!

Not sure about MPSK Local with MAC Authentication, seems risky.

MPSK and an internal RADIUS server definitely fit the bill!

I’m a bit confused about MAC Authentication; I don’t think it provides encryption, which is a key requirement for this scenario.

I practiced a similar question about wireless security, and I feel like EAP-TLS could be relevant here, especially for device authentication.

I think ClearPass Policy Manager might be a good option because it can manage role-based access, but I can't recall if it meets the encryption requirement.

I remember studying MPSK solutions, but I'm not entirely sure if they can handle unique passphrases for each device.

This is right in my wheelhouse. The combination of MPSK local with EAP-TLS and ClearPass Policy Manager is the way to go here. I'm feeling confident about this one.

Whoa, this is a lot to unpack. Encrypted wireless traffic, unique passphrases, and fingerprint access - that's a lot of moving parts. I better read through this a few times.

Hmm, the unique passphrase per device and fingerprint-based access control seem like the key things to focus on. I think I have a good handle on this.

This looks like a tricky one. I'll need to carefully review the requirements and think through the different options.

Okay, I think I've got it. MPSK and ClearPass Policy Manager should cover the encryption and unique passphrase requirements. The fingerprint access can be handled with the role-based policies in ClearPass.

I think the packaging design and the brand name are the two most important factors here. Getting the branding and visual identity right will be key to making the new coffee stand out on the shelves.

Hmm, I'm going to have to say B and E. Local solutions are always the way to go, and who needs RADIUS when you can just make your own rules? *Chuckles*

A and D, for sure. You can't go wrong with a good old-fashioned passphrase and fingerprint combo. Keeps the bad guys out and the good guys in. *Winks*
