,Q1. An organization implements a zero-trust architecture. Which identity
management strategy best supports continuous verification without disrupting user
experience?
A. Single sign-on with SAML assertions
B. Step-up authentication using OAuth 2.0 scopes
C. Passwordless authentication with FIDO2 and conditional access policies
D. Directory services with LDAPS and Kerberos tickets
Correct Answer: C. Passwordless authentication with FIDO2 and conditional access
policies
Rationale: FIDO2 passwordless authentication, combined with conditional access
policies, provides continuous, risk-based verification while minimizing friction. SSO with
SAML, OAuth scopes, or Kerberos still rely on static credentials or tokens that may not
adapt in real time to evolving risk.
Why Wrong:
A - SSO with SAML primarily focuses on initial authentication and lacks the
continuous risk assessment required for zero-trust.
B - OAuth 2.0 scopes delegate authorization but do not inherently provide continuous
authentication or step-up based on risk.
D - LDAPS and Kerberos are traditional authentication protocols that do not support
dynamic, risk-based access decisions.

Q2. A security analyst discovers that a server's certificate was revoked due to key
compromise. Which mechanism ensures clients are immediately informed of the
revocation status?
A. Certificate revocation list (CRL) distribution point
B. Online Certificate Status Protocol (OCSP) with stapling
C. Certificate transparency logs
D. Public key infrastructure (PKI) key escrow
Correct Answer: B. Online Certificate Status Protocol (OCSP) with stapling
Rationale: OCSP with stapling allows the server to present a time-stamped, signed OCSP
response, enabling real-time revocation checks without requiring clients to fetch a CRL.
CRLs are periodic and may introduce latency; certificate transparency logs serve a
different purpose (auditing issuance); key escrow is unrelated to revocation.
Why Wrong:
A - CRLs are updated periodically, so clients may not see the revocation until the next
update.
C - Certificate transparency logs provide an audit trail for issued certificates but do not
convey revocation status.

, D - Key escrow involves storing private keys for recovery, not for revocation status.

Q3. During a network penetration test, you notice that a switch is forwarding frames
to all ports despite the presence of VLANs. Which attack is most likely being
exploited?
A. VLAN hopping via double tagging
B. MAC flooding to overflow the CAM table
C. ARP spoofing to intercept traffic
D. DHCP starvation to exhaust IP addresses
Correct Answer: B. MAC flooding to overflow the CAM table
Rationale: MAC flooding sends numerous fake MAC addresses to overflow the switch's
CAM table, causing it to fall back to flooding frames to all ports, allowing traffic capture.
VLAN hopping via double tagging exploits trunk misconfigurations, not CAM overflow.
ARP spoofing and DHCP starvation target different layers.
Why Wrong:
A - Double tagging exploits trunk port misconfigurations to access other VLANs, but
does not cause flooding to all ports.
C - ARP spoofing poisons the ARP cache to redirect traffic, not the switch's
forwarding behavior.
D - DHCP starvation exhausts DHCP address pools, preventing legitimate clients
from obtaining IPs, not causing frame flooding.

Q4. Which cryptographic protocol is most appropriate for securing communication
between a mobile device and a corporate gateway when the device is behind a
restrictive firewall that only allows outbound HTTPS?
A. IPsec VPN in tunnel mode
B. TLS 1.3 VPN using DTLS
C. SSH over port 22
D. WireGuard on UDP 51820
Correct Answer: B. TLS 1.3 VPN using DTLS
Rationale: TLS 1.3 VPN using DTLS (or TLS) operates over standard HTTPS ports (443),
which is typically allowed through restrictive firewalls. IPsec, SSH (port 22), and
WireGuard (UDP 51820) may be blocked by egress filtering that only permits
HTTP/HTTPS traffic.
Why Wrong:
A - IPsec VPNs often use UDP 500 and ESP (IP protocol 50), which are commonly
blocked by restrictive firewalls.
