True or false: A username by itself authenticates a user to a network.

Network authentication answers the question, “Who or what is ?”
A sign-in requires both a password and a PIN. How many distinct factor categories does this combination use?
- A
Two factors, because the password and PIN are separate credentials
- B
One factor, because both are things the user knows
- C
Two factors, because a PIN is always a possession factor
- D
No factors, because neither credential identifies an account
A company has verified an employee's identity. Which process determines whether that employee may open a particular project folder?
- A
Authentication, because it determines which files the user may open
- B
Authorization, because it determines what an authenticated identity may access
- C
Multi-factor authentication, because the user is opening a protected folder
- D
Enrollment, because a user has requested access to a resource
Multi-factor authentication requires proof from at least different factor categories.
A sign-in requires a password and a one-time code sent to the user's registered phone. Which two factor categories does this combine?
True or false: If repeated push-approval requests appear unexpectedly, a user should approve one in case it is legitimate.
- A
True
- B
False
A device uses a fingerprint to unlock a cryptographic key before connecting to a service. Which description best fits this design?
- A
The fingerprint is sent to the network as the user's password
- B
The fingerprint replaces the need for any device-held credential
- C
The fingerprint locally unlocks a device-held key used to authenticate
- D
The fingerprint determines which resources the user is authorized to access
An organization wants stronger protection against an impostor site capturing and reusing sign-in proof. Which method best meets that goal?
- A
A manually entered code, because a short-lived code cannot be relayed
- B
A properly implemented cryptographic authenticator, because it can bind authentication to the legitimate service or session
- C
A password, because using a unique password prevents phishing
- D
A push prompt, because an approval notification cannot be targeted
A service is improving its password-verification controls. Select all practices supported by current guidance.
- A
Block passwords known to be commonly used or compromised
- B
Limit repeated failed sign-in attempts
- C
Require every user to change passwords on an arbitrary schedule, even when there is no sign of compromise
- D
Allow unlimited failed attempts if the password contains enough characters
Which protocol is used with 802.1X for certificate-based authentication on enterprise Wi-Fi?
Select all practices that help protect stored passwords or reveal suspicious authentication activity.
- A
Store passwords using salted, purpose-built password hashing rather than readable text
- B
Monitor authentication logs for unusual failures, locations, devices, and repeated MFA prompts
- C
Keep passwords in readable text so staff can retrieve them during a sign-in problem
- D
Ignore authentication logs whenever a sign-in succeeds
A company deploys strong MFA but leaves account recovery unchanged. Explain why weak recovery can undermine MFA and identify two measures the company should take to protect recovery.
Which option is a phishing-resistant MFA method to prefer for sensitive accounts when available?
- A
A password combined with a manually entered one-time code
- B
A FIDO-based security key or passkey
- C
Repeated push approvals on a registered phone
- D
A password combined with a PIN
True or false: Requiring a password and a manually entered one-time code reduces the risk from a stolen password, but the code may still be phished or relayed.
- A
True
- B
False
An organization is setting a minimum length for passwords used without MFA. According to the guidance described here, what is the minimum length? Enter the number of characters.
A user receives a push-approval request while not trying to sign in. What is the safest response?
- A
Approve the prompt if it arrives on a registered device, since registration confirms the request is legitimate.
- B
Approve one prompt but ignore any later prompts, since only repeated requests indicate risk.
- C
Do not approve it, and report the unexpected prompt through the organization’s process.
- D
Share the prompt with a colleague so they can determine whether the request is genuine.
An organization uses certificate-based authentication for enterprise Wi-Fi. Why should client devices validate the network’s server certificate?
- A
To help ensure the device is connecting to the legitimate network rather than sending credentials to a rogue network.
- B
To let the device skip authentication whenever a familiar network name is detected.
- C
To ensure that every Wi-Fi user receives broad access after presenting any certificate.
- D
To replace the need for the client to authenticate with its own certificate.
What process determines what an authenticated identity is allowed to do? Enter the process name.
A team is designing a password database. Which storage approach best follows the recommended practice?
- A
Store passwords as readable text but restrict database access to administrators.
- B
Store passwords using salted, purpose-built password-hashing methods.
- C
Encrypt passwords with a shared key and retain the key alongside the password database.
- D
Save only the password’s length and let users recover the original password from it.
