What is the key difference between one-way CHAP and mutual CHAP?

Mutual CHAP encrypts the data, while one-way CHAP does not.

Mutual CHAP authenticates both the initiator and the target, while one-way CHAP authenticates only the initiator.

Mutual CHAP requires a certificate, while one-way CHAP does not.

Mutual CHAP uses a longer secret than one-way CHAP.

Which of the following is a common location where CHAP credentials are configured on a Windows iSCSI initiator?

In the Control Panel under 'Internet Options'

In the registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iSCSI

In the Device Manager under network adapters

In the iSCSI Initiator Properties, under the 'Configuration' tab

An administrator is configuring CHAP on an E-Series storage system for a new iSCSI initiator. The initiator will use a CHAP username of 'host1' and a secret of 'Secret123'. Where should the administrator configure these credentials on the E-Series system?

In the volume access settings for the LUN.

In the initiator group settings for the specific host.

In the global CHAP settings for the storage system.

In the network interface settings for the iSCSI port.

A company requires mutual CHAP for all iSCSI connections. They have two E-Series systems and a mix of Linux and Windows initiators. After enabling mutual CHAP, Linux initiators connect successfully, but Windows initiators fail with an authentication error. What is the most likely reason?

Linux initiators use a different CHAP protocol version.

The Windows initiators are using an outdated iSCSI driver.

The E-Series system does not support mutual CHAP with Windows.

Windows initiators require a separate setting for mutual CHAP, which was not configured.

What is the primary purpose of CHAP in an iSCSI environment?

To assign IP addresses to iSCSI initiators

To encrypt the data being transferred between the initiator and target

To authenticate the initiator and optionally the target during session establishment

To compress the iSCSI packets to improve performance
