Question 2

In MSTP, each MSTI calculates an independent spanning tree by using the RSTP algorithm.

Accepted Answer

MSTP (Multiple Spanning Tree Protocol) uses MSTIs (Multiple Spanning Tree Instances) to calculate independent spanning trees, and each MSTI uses the RSTP (Rapid Spanning Tree Protocol) algorithm for this purpose.

Question 3

Which of the following route prefixes match this IP-prefix-filter? (Choose three.) "ipip-prefix test index 10 permit 10.0.0.0 16 greater-equal 24 less-equal 28"

Accepted Answer

The filter permits prefixes within the 10.0.0.0/16 range with subnet masks between /24 and /28 inclusive. Choices B, C, and D meet these criteria.

Question 4

Which of the following LSPs are established in Downstream Unsolicited (DU) label advertisement mode and ordered label distribution control mode? (Choose three.)

Accepted Answer

In Downstream Unsolicited (DU) label advertisement mode, LSRs distribute labels to upstream neighbors without waiting for a request. In ordered label distribution control mode, the egress node initiates the label distribution. Choices B, C, and D describe processes consistent with these modes, where labels are bound to FECs and advertised, and label mapping messages are sent and processed.

Question 5

The unicast and multicast technologies are both outstanding in solving the problem of one source and "multiple" destinations for efficient P2MP data transmission.

Accepted Answer

The answer of The unicast and multicast technologies are both...

Question 6

When the Hold Time parameter negotiated between two BGP peers is 0, no Keepalive messages will be sent.

Accepted Answer

When the Hold Time is set to 0, it indicates that the BGP session should not expect Keepalive messages, effectively disabling the hold timer mechanism.

Question 7

Which following module is not the functional module of NFV framework?

Accepted Answer

OSS (Operations Support System) is not a functional module of the NFV framework; it is part of traditional network management systems.

Question 8

Which of the following statements regarding Router-LSA connection type (Type) is false?

Accepted Answer

P2MP (Point-to-Multipoint) describes a connection from the local router to multiple endpoints, not specifically to multiple neighboring routers.

Question 10

A DHCP client needs to obtain an IP address from the DHCP server when accessing a network for the first time. When the client accesses the network again, which of the following statements are true? (Choose two.)

Accepted Answer

The DHCP client only needs to broadcast a DHCP Request packet containing the IP address obtained last time, but does not need to send a DHCP Discover packet again.After receiving the DHCP Request packet, the DHCP server returns a DHCP ACK packet if the requested IP address is not allocated to another client.

Question 11

Which of the following are roles in port mirroring? (Choose three.)

Accepted Answer

Mirrored port, local observing port, and remote mirroring port are all roles in port mirroring.

Question 12

Which of the following statements regarding the OSPF protocol is false?

Accepted Answer

An ABR (Area Border Router) maintains separate LSDBs (Link State Databases) for each area it is connected to, not the same LSDB for all areas.

Question 13

Accepted Answer

The answer of Which of the following statements regarding join...

Question 14

Which of the following protocols support the any-source multicast (ASM) model? (Choose two.)

Accepted Answer

PIM-SSM and IGMPv3, and MBGP and MSDP support the any-source multicast (ASM) model.

Question 15

Huawei switches provide port isolation. Which of the following statements regarding port isolation is false?

Accepted Answer

If interface A is isolated from interface B, packets sent from interface A cannot reach interface B, and packets sent from interface B cannot reach interface A. Port isolation is bidirectional, not unidirectional.

Question 16

Which of the following statements regarding ABR is false?

Accepted Answer

The answer of Which of the following statements regarding ABR...

Question 17

Ethernet supports broadcast. Once a network loop occurs, this simple broadcast mechanism will cause catastrophic consequences. Which of the following symptoms may be caused by a loop? (Choose all that apply.)

Accepted Answer

A network loop can cause excessive broadcast traffic, leading to high CPU usage, inability to log in remotely, increased broadcast packets, and packet loss in ping tests.

Question 18

Which of the following statements about DR are true? (Choose three.)

Accepted Answer

B) The source's DR sends Register messages to the RP to inform it about the source.  C) The receiver's DR sends Join messages to join a multicast group.  D) An Assert winner is determined by metrics and may not necessarily be the DR.
