3. You're reviewing a certificate chain and you notice that one of the certificates has expired. What is the potential impact of this expired certificate?
The certificate chain will be invalidated and all connections using that chain will fail
The certificate will still be valid for a grace period of 30 days
The certificate will continue to be valid indefinitely
The certificate will only be invalidated if it is used for signing new certificates
Question 3 of 10

4. You're investigating a security incident and you suspect that a rogue certificate has been issued by a compromised CA. Which of the following is the BEST way to identify and revoke the rogue certificate?
Use a certificate revocation list (CRL)
Use an online certificate status protocol (OCSP) responder
Manually check each certificate in the CA's database
Use a third-party certificate monitoring service
Question 4 of 10

5. You're designing a PKI for a large organization with multiple locations. Which of the following is the BEST approach to managing the PKI?
Implement a single CA for the entire organization
Implement multiple CAs, each responsible for a specific geographic region
Implement a hierarchical PKI with a root CA and multiple subordinate CAs
Implement a mesh PKI where each CA trusts all other CAs
Question 5 of 10

6. You're implementing a PKI for a web application that requires high availability. Which of the following is the BEST approach to ensuring that the PKI remains available in the event of a CA failure?
Use a single CA with no backups
Use multiple CAs in a failover configuration
Use a cloud-based CA service that provides high availability
Use a hardware security module (HSM) to store the CA's private key
Question 6 of 10

7. You're reviewing a certificate request and you notice that the subject alternative name (SAN) field contains both a domain name and an IP address. Which of the following is the potential security risk associated with this?
The certificate can be used to impersonate both the domain name and the IP address
The certificate is invalid and will not be accepted by browsers
The certificate is valid, but it can only be used for domain name validation
The certificate is valid, but it can only be used for IP address validation
Question 7 of 10

8. You're implementing a PKI for a mobile application that requires end-to-end encryption. Which of the following is the BEST approach to managing the private keys on the mobile devices?
Store the private keys in the application's database
Store the private keys in the device's keychain
Store the private keys on a remote server
Store the private keys on a hardware security module (HSM)
Question 8 of 10

9. You're investigating a security incident and you suspect that a phishing attack is using a fraudulent certificate to impersonate a legitimate website. Which of the following is the BEST way to identify and block the fraudulent certificate?
Use a certificate revocation list (CRL)
Use an online certificate status protocol (OCSP) responder
Manually check the certificate against a known-good certificate
Use a third-party certificate monitoring service
Question 9 of 10

10. You're reviewing a PKI implementation and you notice that the certificate chain contains a self-signed root certificate. Which of the following is a potential security risk associated with this?
The certificate chain is invalid and will not be accepted by browsers
The root certificate can be compromised, allowing an attacker to impersonate any website
The root certificate is only valid for a short period of time
The root certificate is stored on a publicly accessible server
