What the exam tests

What to know about Security Concepts

Security Concepts questions test whether you can apply the concept in context, not just recognise a definition.

How the topic appears in realistic exam-style scenarios.

Which detail in the question changes the correct answer.

How to eliminate plausible but wrong options.

How to connect the question back to the wider exam objective.

Watch out for

Common Security Concepts exam traps

▸Answering from memory before reading the full scenario.
▸Missing a constraint such as cost, availability, security, scope or command context.
▸Choosing a broad answer when the question asks for the most specific fix.
▸Ignoring why the wrong options are tempting.

Which security model requires that all subjects and devices are untrusted by default, and access is granted only after verification, regardless of the network location?

Trap 1: Least Privilege

Least Privilege is a principle of granting minimal necessary access, but it is not the overarching model described.

Trap 2: Defense in Depth

Defense in Depth uses multiple layers of security, but does not inherently distrust all subjects by default.

Trap 3: CIA Triad

The CIA Triad is a model for confidentiality, integrity, and availability, not an access control model.

Which security model requires that all subjects and devices are untrusted by default, and access is granted only after verification, regardless of the network location?

A security analyst notices unusual outbound traffic from an internal host to a known malicious IP address on TCP port 4444. The host is also exhibiting high CPU usage and running an unknown process. Which type of malware is most likely present?

An organization wants to ensure that digital certificates issued by its internal CA are validated for revocation in real-time. Which protocol should be implemented to allow clients to check certificate status without downloading a full CRL?

During a penetration test, an attacker sends a malicious payload to a web application that causes the server to execute arbitrary SQL commands on the backend database. Which type of attack is being performed?

A security administrator is configuring a Cisco Firepower NGFW to detect and block application-layer DDoS attacks. Which type of DDoS attack is characterized by overwhelming a server with incomplete HTTP requests, causing resource exhaustion?

Which cryptographic algorithm is considered deprecated and should be avoided due to known vulnerabilities, especially when used in digital signatures and certificate signing?

An attacker uses ARP spoofing to intercept traffic between two devices on the same subnet. After successfully becoming a man-in-the-middle, the attacker can then perform which further attack to downgrade HTTPS connections to HTTP?

In a PKI hierarchy, which component is responsible for issuing and revoking certificates for end entities, and is directly subordinate to the root CA?

A security engineer is evaluating authentication methods. Which authentication factor category does a fingerprint scanner fall under?

Which Cisco security product is primarily designed to provide DNS-layer security by blocking requests to malicious domains?

A network administrator is configuring an ASA to enforce that traffic between two internal zones must be inspected by the firewall. Which security principle is being applied?

An attacker performs a DNS cache poisoning attack on a recursive DNS server. What is the primary impact of this attack?

A security analyst is investigating a potential insider threat. Which TWO indicators are most commonly associated with malicious insider activity? (Choose two.)

A company is implementing a Zero Trust architecture. Which THREE principles are core to the Zero Trust model? (Choose three.)

A network engineer is tasked with securing email communications. Which TWO Cisco products are specifically designed for email security? (Choose two.)

A security analyst is reviewing logs and sees multiple failed login attempts from a single IP address, followed by a successful login. Which type of attack does this represent?

An organization wants to implement a security model where no user or device is trusted by default, regardless of whether they are inside or outside the network perimeter. Which concept does this describe?

A security engineer is configuring a Cisco Firepower NGFW to detect and block a new malware variant that communicates with a command-and-control server using encrypted DNS queries. Which Cisco security product is best suited to provide visibility into this malicious DNS traffic?

Which of the following is an example of a passive reconnaissance technique?

A company deploys a solution that uses a root certificate authority (CA) and intermediate CAs to issue certificates. What is the term for the hierarchical structure of certificates from the root CA to the end entity?
