NEW QUESTION # 47
IPS signatures describe the characteristics of attack behaviors on the network. The firewall detects and defends against attacks by comparing data flows with IPS signatures.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
Explanation From HCIA-Security documents:
IPS works by identifying malicious traffic patterns and behaviors in network data. An IPS signature is a set of detection rules that describe known attack characteristics, such as specific byte sequences in payloads, abnormal protocol fields, exploit patterns, or behavior indicators that match a recognized threat. When traffic passes through the firewall with IPS enabled, the device performs protocol decoding and (when needed) stream or application data reassembly so it can inspect complete content instead of isolated packets. After that, it compares the reconstructed traffic against the IPS signature database. If a match is found, the firewall determines the traffic is malicious and then takes the configured action, such as blocking packets, resetting the connection, discarding the session, and generating logs/alarms for visibility and auditing. This signature-based comparison is a core detection method of IPS and is why keeping the signature library updated is important:
new attack techniques require new or improved signatures. Therefore, the statement is correct: the firewall detects and defends by comparing data flows with IPS signatures.
NEW QUESTION # 48
Which security zone can be deleted and its priority can be reconfigured?
- A. Trust
- B. DMZ
- C. ISP
- D. Untrust
Answer: B
Explanation:
Explanation From HCIA-Security documents:
Huawei firewalls use security zones to classify interfaces and apply interzone access control and security policies. Some zones are predefined default zones that are built into the system to represent common network roles, such as Trust and Untrust. These default zones are foundational for typical deployments and are generally not allowed to be deleted, because many policy and security mechanisms rely on them as standard references.
In contrast, DMZ is commonly used as a semi-trusted zone for servers that must be reachable from the Internet while still being isolated from the internal network. On Huawei firewalls, DMZ is treated as a configurable zone: administrators can create it when needed, remove it when it is not required, and adjust its priority value so that zone-based matching and policy selection behave as intended in multi-zone deployments.
"ISP" is not a standard default security zone name in the typical Huawei firewall zone model presented at HCIA level. Therefore, among the options, DMZ is the zone that can be deleted and whose priority can be reconfigured.

NEW QUESTION # 58
How frequently should antivirus signature databases be updated to ensure the effectiveness of an antivirus program or software?
- A. Half a month
- B. Every day
- C. Every month
- D. Three months
Answer: B
Explanation:
Explanation From HCIA-Security documents:
Antivirus software relies heavily on its signature database to identify known malware, suspicious files, and malicious behaviors. Because new threats appear continuously and existing malware is frequently modified to evade detection, the signature library must be updated very often to keep protection effective. Updating every day is the best practice in most enterprise and personal environments, and many antivirus products actually update multiple times per day automatically.
If signatures are updated only monthly , half-monthly , or every three months , there is a large window where newly released malware samples and variants will not be recognized, increasing the chance of infection and successful compromise. Daily updates reduce this exposure window and ensure the antivirus engine has the newest detection patterns, reputation indicators, and sometimes updated heuristic rules released by the vendor.
In addition, daily updates align with operational security expectations: endpoints are exposed to internet content, email attachments, removable media, and downloads on a constant basis, so outdated signatures quickly become a weak link. Therefore, the correct answer is Every day .
