1On a Huawei USG firewall, which sequence correctly describes the matching order of an advanced security policy that uses 5-tuple plus user, application, URL, and time conditions?

A.Source/destination zone, source/destination address, user, service, application, URL category, time-range, action

B.Action, time-range, user, source/destination zone, application, URL category, source/destination address, service

C.User, source/destination address, action, source/destination zone, service, application, URL category, time-range

D.Service, source/destination zone, source/destination address, action, user, time-range, application, URL category

Explanation: USG security policy matching first uses zones (inter-zone direction), then 5-tuple (source/dest IP, service), then identity dimensions (user/user-group), then content dimensions (application from SA database, URL category, file/content profiles), then time-range, and finally an action (permit/deny) with optional content profiles. Action is the result, not a match condition, and time-range is evaluated as a condition before the action is taken.

2An administrator wants a Huawei USG to translate IPv6 hosts in the trust zone so they can reach an IPv4-only server in the untrust zone. Which feature is required?

A.NAT-PT (Network Address Translation - Protocol Translation)

B.Source NAT with PAT

C.Twice-NAT

D.NAT Server (static destination NAT)

Explanation: NAT-PT translates between IPv4 and IPv6 address families and is the Huawei feature used to let IPv6-only clients reach IPv4-only servers (or vice-versa). Source NAT, twice-NAT, and NAT Server all operate within the same address family (IPv4 to IPv4 or IPv6 to IPv6) and cannot bridge protocols.

3Which statement BEST describes the function of the root system (root vsys) on a Huawei USG that has multiple virtual systems configured?

A.It is the management system that owns physical interfaces and resource classes assigned to virtual systems

B.It is automatically deleted as soon as the first non-root vsys is created

C.It can only forward traffic between non-root virtual systems and never to physical interfaces

D.It shares its session table directly with every other virtual system for high availability

Explanation: On Huawei USG firewalls the root system (root-vsys) is the default virtual system that owns physical interfaces, the global routing instance, and the resource class definitions. Administrators bind interfaces and assign resource quotas to non-root vsys from the root system. Each vsys has its own independent session table; sessions are not shared.

4A Huawei USG with two ISP uplinks must steer HTTP traffic destined to ISP1 prefixes out of interface GE1/0/1 and HTTPS traffic destined to ISP2 prefixes out of GE1/0/2. Which feature combination is BEST suited?

A.Static routing only

B.Policy-based routing (PBR) plus ISP route (ISP address library)

C.Source NAT plus equal-cost multi-path

D.DNS transparent proxy plus default route

Explanation: ISP route uses Huawei's pre-loaded ISP address libraries to match destinations belonging to a particular ISP and forward them through the corresponding link. PBR matches additional conditions (such as application HTTP/HTTPS or source) to override the routing table. Combining the two gives ISP-aware, application-aware multi-egress steering.

5Which Huawei USG link load-balancing algorithm distributes new sessions in proportion to a link's configured weight?

A.Source-IP hash

B.Round robin

C.Weighted round robin

D.Least sessions

Explanation: Weighted round robin (WRR) distributes new sessions across multiple egress links in proportion to each link's configured weight. Plain round robin ignores weight, source-IP hash is for session stickiness, and least-sessions distributes based on current session count rather than capacity weight.

6What is the purpose of DNS transparent proxy on a Huawei multi-egress USG?

A.To intercept client DNS queries and rewrite them to use the DNS server of the egress link that will be used

B.To block all DNS queries that resolve to URL categories on a blacklist

C.To encrypt all DNS queries between the client and the firewall

D.To replace the firewall's own DNS resolver with the upstream ISP's

Explanation: DNS transparent proxy intercepts client DNS queries and rewrites the destination DNS server so that resolution happens via the same ISP that will carry the resulting traffic. This avoids the asymmetric path problem where ISP-A returns a CDN node optimized for ISP-A but the user actually exits via ISP-B. It is an integral part of multi-egress optimization.

7An administrator must guarantee at least 2 Mbps and cap each user in the marketing user-group at 5 Mbps of egress bandwidth. Which Huawei USG bandwidth feature applies?

A.Per-IP bandwidth inside a bandwidth policy with guaranteed and maximum bandwidth values

B.QoS policing only with CIR set to 2 Mbps

C.Queue scheduling using strict priority queues

D.Application-layer rate limiting via SA database only

Explanation: Bandwidth policies on the USG support per-IP bandwidth limits (each IP gets its own guaranteed minimum and maximum) inside a policy that matches users, applications, time, etc. Setting guaranteed bandwidth = 2 Mbps and maximum bandwidth = 5 Mbps achieves the requirement. Pure policing or scheduling alone does not enforce per-user minimums.

8Which Huawei queue-scheduling mode forwards packets in queues strictly in order of priority and never services a lower-priority queue while a higher one has packets?

A.Weighted Fair Queuing (WFQ)

B.Strict Priority (PQ)

C.Class-Based Weighted Fair Queuing (CBWFQ)

D.Low Latency Queuing (LLQ) without priority class

Explanation: Strict Priority Queuing (PQ) always services the highest-priority non-empty queue first and only serves lower queues when all higher queues are empty. WFQ and CBWFQ share bandwidth proportionally between queues, and LLQ without a priority class behaves like CBWFQ.

9Which IPsec feature lets a peer detect that the other end has gone silent and tear down the SA proactively, rather than waiting for the SA lifetime to expire?

A.Perfect Forward Secrecy (PFS)

B.Dead Peer Detection (DPD)

C.Anti-replay window

D.NAT Traversal (NAT-T)

Explanation: Dead Peer Detection sends keep-alive R-U-THERE messages over an established IKE SA. If a peer fails to acknowledge after the configured retry/interval, the local peer assumes the remote is dead and tears down both IKE and IPsec SAs, allowing immediate failover. PFS, anti-replay, and NAT-T address completely different functions (key independence, replay protection, NAT transparency).

10When IPsec NAT Traversal (NAT-T) is enabled, which UDP port does it use to encapsulate ESP packets?

A.UDP 500

B.UDP 4500

C.UDP 1701

D.UDP 50

Explanation: Once NAT is detected during IKE phase 1 (using NAT-D payloads), both peers move IKE and ESP traffic to UDP 4500. UDP 500 is plain IKE without NAT-T, UDP 1701 is L2TP, and ESP itself is IP protocol 50, not a UDP port — protocol 50 is precisely what cannot traverse NAT, which is why UDP 4500 encapsulation is needed.

Huawei HCIP-Security (H12-721/722/723) Study Tips from Top Performers

1Take the exams in order (CISN -> CSSN -> CTSS) so VPN and policy fundamentals are solid before content security and analytics

2Memorize the USG advanced policy match order: zone -> 5-tuple -> user -> application -> URL category -> time-range -> action with content profile

3Know NAT-PT (IPv6<->IPv4 protocol translation) vs NAT-T (IPsec NAT traversal on UDP 4500) — they are unrelated but easy to confuse

4IPsec PFS forces a fresh DH exchange per Phase 2 SA so past SAs stay safe even if the current master key is later compromised

5DSVPN is Huawei's DMVPN equivalent — spokes register to the hub, then build on-demand spoke-to-spoke IPsec tunnels

6Tune noisy IPS signatures with exception rules (per source IP) instead of disabling the whole signature globally

7File fingerprinting catches partial leaks of registered documents even after edits; regex catches structured data like SSN/credit-card

8DNS sinkholing fed by threat-intel feeds defeats fast-flux botnets that rotate C2 domains every few minutes

9AntiDDoS terms: traction = BGP diversion to scrubbing center, dilution = active probing/marking, scrubbing = filtering and re-injection

10SM2/SM3/SM4 are the GM/T (Chinese national) crypto algorithms; SM4 is a 128-bit block / 128-bit key symmetric cipher used in IPsec/TLS
