Huawei HCIP-Security V4.0 Sample Questions (Q49-Q54):

NEW QUESTION # 49
Which of the following methods are used by flood attacks to cause denial of services?(Select All that Apply)

A. Exhaust available bandwidth.
B. Exhaust network device resources.
C. Control network host rights.
D. Exhaust server-side resources.

Answer: A,B,D

Explanation:
Comprehensive and Detailed Explanation:
* Flood attacks (DoS/DDoS) overwhelm network resources, preventing normal users from accessing services.
* Correct answers:
* A. Exhaust available bandwidth# Large amounts of traffic saturate the network.
* B. Exhaust server-side resources# High CPU/memory usage causes server crashes.
* D. Exhaust network device resources# Firewalls, routers, and switches become overloaded.
* Why is C incorrect?
* Controlling host rights is related to hacking, not flooding attacks.

NEW QUESTION # 50
If data filtering is configured on the firewall but is not correctly referenced in the security policy, the data that should be blocked can still be transmitted normally.

A. FALSE
B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
* Firewalls enforce security policies based on rules defined by the administrator.
* Data filtering rules must be explicitly referenced in security policies to take effect.
* Why is this statement true?
* If a filtering rule exists but is not linked to a security policy, it will not apply to network traffic.

NEW QUESTION # 51
Which of the following protocols can be encapsulated through GRE over IPsec?(Select All that Apply)

A. IPX
B. OSPF
C. VRRP
D. IPv6

Answer: A,B,C,D

Explanation:
Comprehensive and Detailed Explanation:
* IPsec does not support non-IP traffic (e.g., multicast, routing protocols, or legacy protocols like IPX).
* GRE over IPsec allows encapsulation of:
* A. IPX# Legacy protocol supported via GRE.
* B. VRRP# Uses multicast, which GRE supports.
* C. IPv6# GRE tunnels can carry IPv6 over IPv4.
* D. OSPF# Uses multicast (224.0.0.5 & 224.0.0.6), requiring GRE.
* Why are all options correct?
* GRE over IPsec is required for non-unicast and legacy protocols.

NEW QUESTION # 52
Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.

Answer:

Explanation:

Explanation:
Intrusion Prevention Systems (IPS) in firewalls follow amulti-step processto detect and mitigate threats. The steps occur in a logical sequence:
1##Step 1: Identifies and Parses Application-Layer Protocols
* The firewall firstidentifies the protocol being used(e.g., HTTP, FTP, DNS, SMTP).
* Parsing the protocol helps the IPS engineunderstand how the data is structuredand what types of attacks might be embedded.
* This step is crucial for detectingprotocol-based attackslike SQL injection or cross-site scripting (XSS).
2##Step 2: Reassembles IP Fragments and TCP Flows
* Attackers oftensplit malicious payloads across multiple packetsto evade detection.
* The firewallreassembles fragmented packets and TCP flowsto reconstruct the full data stream.
* This step is critical for detectingevasion techniques such as fragmented attacks or out-of-order packet attacks.
3##Step 3: Performs Signature Matching
* Once the full data stream is reassembled, the IPScompares it against known attack signatures.
* Signature matching helps detect:
* Malware patterns(e.g., botnets, Trojans).
* Exploits targeting vulnerabilitiesin software and operating systems.
* Firewalls usepredefined signature databasesthat are regularly updated.
4##Step 4: Performs the Response Action Based on the IPS Profile
* If an attack is detected, the firewall takes anaction based on the IPS policy:
* Block the traffic(drop malicious packets).
* Alert the administrator(generate logs and alerts).
* Rate-limit traffic(slow down potential attack sources).
* Theresponse mechanism is customizablebased on security requirements.

NEW QUESTION # 53
Which of the following statements is true about the incoming traffic in the firewall virtualsystem?
(Select All that Apply)

A. Traffic from the public network interface to the private network interface is limited by the outbound bandwidth.
B. Traffic from the public network interface to the private network interface is limited by the inbound bandwidth.
C. Traffic from the private network interface to the public network interface is limited by the outbound bandwidth.
D. Traffic from the private network interface to the public network interface is limited by the inbound bandwidth.

Answer: B,C

Explanation:
Comprehensive and Detailed Explanation:
* Inbound bandwidth= Trafficenteringthe firewall.
* Outbound bandwidth= Trafficleavingthe firewall.
* Correct answers:B. Public # Private traffic is controlled by inbound bandwidth.D. Private # Public traffic is controlled by outbound bandwidth.
