問題 #66
A restaurant distribution center recently suffered a password spray attack targeting the Cisco Secure Firepower Threat Defense VPN headend. The attack attempts to gain unauthorized access by trying common passwords across many accounts. The attack poses a significant security threat to the organization's remote access infrastructure. To enhance the security of the VPN setup and minimize the risk of similar attacks in the future, the IT security team must implement effective mitigation measures. Which technique effectively reduces the risk of this type of attack?

答案：C

解題說明：
In the context of Designing Cisco Security Infrastructure, protecting Remote Access VPN (RAVPN) against brute-force and password spray attacks is a critical objective. On Cisco Firepower Threat Defense (FTD) and Adaptive Security Appliance (ASA) platforms, theDefaultWEBVPNGroupandDefaultRAGroupare the landing points for any connection request that does not specify a valid Group Alias or Group URL. Attackers frequently target these default profiles because they are often left with "None" as the authentication method, allowing the attacker to probe for valid usernames without immediate rejection.
By selectingOption D, the security designer ensures that any attempt to access the VPN via these default profiles requires valid AAA credentials. According to Cisco's hardened design guides, it is best practice to point these default profiles to a "sinkhole" AAA server or a local database with no users. This forces the password spray attack to fail at the initial authentication phase before any sensitive information is leaked or unauthorized access is granted. While Option A (ACLs) provides a temporary fix, it is ineffective against distributed attacks using rotating IP addresses. Option B (Disabling aliases) is a good obfuscation technique but doesn't stop an attacker from hitting the default profile. Option D provides a structural mitigation that aligns with theCisco SAFEarchitectural principle of reducing the attack surface by securing every possible entry vector into the private infrastructure.


問題 #67
What is the primary benefit of conducting a root cause analysis after a security incident?

答案：C

解題說明：
Root cause analysis focuses on identifying the underlying cause of a security incident. This enables organizations to improve system design, controls, or processes so that similar incidents do not happen again, rather than only fixing symptoms.


問題 #68
A pharmaceutical company needs hub-and-spoke VPN topology. The design must be capable of building either partial or full mesh overlay networks. Which VPN solution must be implemented in the environment?

答案：B

解題說明：
Dynamic Multipoint VPN (DMVPN) supports hub-and-spoke topologies while allowing flexibility to build partial or full mesh overlays as needed. It provides scalable and dynamic VPN tunnels without requiring static configuration, making it the best fit for the requirement.


問題 #69
A developer company recently made a contract with new customer in the financial space. The customer has multiple remote sites and requires a VPN solution with the highest encryption.
Which protocol must be used in IPsec Phase 2?

答案：D

解題說明：
In IPsec Phase 2, the Encapsulating Security Payload (ESP) protocol is used to provide confidentiality, integrity, and authentication for VPN traffic. ESP ensures the highest encryption and protection for sensitive financial data across remote sites.


問題 #70
Which two metrics are important for evaluating the performance of automated security response workflows? (Choose two.)

答案：B,C

解題說明：
MTTD measures how quickly incidents are detected, and MTTR measures how quickly they are resolved. Together, they indicate the effectiveness of automated security response workflows.


問題 #71
