Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q185-Q190):

NEW QUESTION # 185
Which of the following is used as the destination port for single-hop BFD?

A. UDP port 4784
B. UDP port 3784
C. TCP port 3784
D. TCP port 4784

Answer: B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* Single-Hop BFD:
* Single-hop BFD is used for detecting link failures in directly connected devices.
* It uses UDP port 3784 for communication.
* Multi-Hop BFD:
* For multi-hop scenarios, BFD uses UDP port 4784 to ensure end-to-end connectivity.
Incorrect Options:
* TCP ports 3784 and 4784 (C and D): BFD does not use TCP.
References:
* HCIA-Datacom Study Guide, Chapter: BFD Ports and Functions
* Huawei BFD Configuration Details

NEW QUESTION # 186
On an OSPF network, one router with P2P as the network type is directly connected to another router with P2MP as the network type. If the Hello intervals on the two routers are changed to be the same, neighbor relationship establishment and LSDB synchronization are not affected.

A. TRUE
B. FALSE

Answer: B

Explanation:
The scenario describes a mismatch in OSPF network types between two connected routers: one set to Point-to- Point (P2P) and the other set to Point-to-Multipoint (P2MP). While aligning Hello intervals may seem sufficient for establishing an OSPF neighbor relationship, the fundamental mismatch in network types introduces issues.
* OSPF Network Types
* P2P: Assumes a direct connection with a single neighbor, uses faster convergence and simpler LSDB synchronization.
* P2MP: Supports multiple neighbors on a single interface, requiring different handling for DR
/BDR roles and LSDB updates.
* Impact of Network Type Mismatch
* If Hello intervals are aligned, adjacency establishment might occur. However, mismatched network types affect neighbor role assignment and LSDB synchronization.
* P2P expects a direct link and would handle updates differently than P2MP, which assumes multiple neighbors. This leads to inconsistencies in route calculation and forwarding.
* HCIP-Datacom-Core Reference
* OSPF Basics and Configurationclearly outlines the criticality of consistent network type configuration for stable OSPF operation.
* Lab examples in the HCIP Datacom Lab Guidefurther demonstrate the consequences of such mismatches, including unstable neighbor states and incomplete LSDB synchronization.
Hence, the statement that neighbor relationships and LSDB synchronization remain unaffected is incorrect.
Proper OSPF operation requires matching network types in addition to aligned Hello intervals.

NEW QUESTION # 187
VRRP is implemented based on the priority and preemption functions of VRRP routers. Which of the following statements is false about the VRRP solution?

A. When preemption is enabled, a backup device preempts the master role if it has a higher priority than the current master.
B. Even if the VRRP device is the IP address owner, it still needs to participate in the election and does not directly transition to the Master state when receiving a message indicating that the interface goes Up.
C. The master periodically sends VRRP Advertisement packets in the VRRP group to advertise its configurations such as the priority.
D. When preemption is disabled, a backup device does not preempt the master role even if it has a higher priority than the current master, provided that the current master is working properly.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* A. TRUE # If preemption is enabled, a higher-priority router can take over as the Master.
* B. TRUE # If preemption is disabled, the current Master remains active even if a higher-priority router joins.
* C. TRUE # The Master router sends VRRP Advertisement packets to maintain its role.
* D. FALSE # If a VRRP router is the IP address owner, it automatically becomes the Master without needing to participate in an election.
# Reference: Huawei HCIA-Datacom Study Guide, VRRP Priority and Preemption Mechanisms.

NEW QUESTION # 188
Which of the following statements regarding the stateful inspection firewall is true?

A. The stateful inspection firewall needs to match the rules for each incoming packet.
B. The stateful inspection firewall only needs to match the first data packet against a rule, and the subsequent packets of the connection are matched directly in the state table.
C. When the stateful inspection firewall checks packets, packets of one same connection are not correlated.
D. Because UDP is a connectionless protocol, so the stateful inspection firewall cannot match UDP packets with the status table.

Answer: B

Explanation:
A stateful inspection firewall tracks the state of network connections and only matches the initial packet against its rule set. Subsequent packets in the same connection are matched in the state table. Contrary to this, UDP packets can be inspected by correlating them with connection states, and packets in a single connection are always correlated .

NEW QUESTION # 189
Similar to the OSPF DR, the IS-IS DIS needs to be elected on a broadcast network. However, the OSPF DR is preemptive by default, whereas the IS-IS DIS is not preemptive by default.

A. FALSE
B. TRUE

Answer: B

Explanation:
DIS and DR Election
* The IS-IS Designated Intermediate System (DIS) is responsible for generating and updating pseudonode LSPs on a broadcast network.
* Unlike OSPF DR, the IS-IS DIS does not preempt by default. This behavior avoids unnecessary flapping in the network due to frequent DIS re-elections.
HCIP-Datacom-Core Reference
* The characteristics of DIS and DR behavior are explained in IS-IS network operation chapters.
