Question 1

When an edge port is in the protected state on an RSTP network, which of the following operations is performed by the edge port immediately after receiving BPDUs?

Accepted Answer

The answer of When an edge port is in the...

Question 2

What are the advantages of subnetting? (Choose two.)

Accepted Answer

Subnetting isolates broadcast traffic by dividing a network into smaller, manageable segments, and it increases IP address usage by allowing more efficient allocation of addresses within a network.

Question 3

Which of the following statements regarding BGP is false?

Accepted Answer

BGP is a path vector protocol, not a link-state routing protocol.

Question 4

A VLAN can be regarded as a ( )

Accepted Answer

A VLAN is a broadcast domain, meaning that all devices within the VLAN can communicate with each other without the need for a router.

Question 5

Which of the following commands is used to display check information of IGMP enabled interface?

Accepted Answer

The command "[Quidway]displayigmp interface" is used to display information about IGMP (Internet Group Management Protocol) on an interface.

Question 6

Which of the following BGP attributes are well-known community attributes? (Choose all that apply.)

Accepted Answer

No_Export and No_Advertise are well-known community attributes.

Question 7

Which of the following procedures are included in IS-IS route calculation? (Choose all that apply.)

Accepted Answer

The answer of Which of the following procedures are included...

Question 8

Compared with OSPF, which of the following statements regarding IS-IS are true? (Choose all that apply.)

Accepted Answer

The answer of Compared with OSPF, which of the following...

Question 9

Which of the following configuration can enable indirectly connected EBGP peers to establish a connection normally?

Accepted Answer

The "peer ebgp-max-hop" command allows EBGP peers that are not directly connected to establish a connection by increasing the maximum number of hops allowed.

Question 10

Which of the following statements regarding MUX VLAN is true?

Accepted Answer

The MUX VLAN contains a principal VLAN and subordinate VLANs, which are classified into subordinate separate VLANs and subordinate group VLANs. Interfaces in the subordinate group VLAN can communicate with each other.

Question 11

On a STP network, which of the following BPDUs are sent during flooding of information throughout the network due to STP topology change?

Accepted Answer

All BPDUs with the TCN, TCA, and TC flags are sent during flooding of information throughout the network due to STP topology change.

Question 12

One route-policy may have several nodes and each node has a node ID. Each node may have "multiple" if-match and apply clauses. Which of the following statements are true? (Choose two.)

Accepted Answer

Different nodes are in an OR relationship, meaning that if any one of the nodes matches the traffic, the policy is applied. If-match clauses under a node are in an AND relationship, meaning that all of the if-match clauses under a node must match the traffic in order for the policy to be applied.

Question 13

Which of the following statements are true regarding VRRP?

Accepted Answer

By default, in VRRP (Virtual Router Redundancy Protocol), only the Master router processes the data packets sent to the virtual router.

Question 14

Which of the following route selection tools can be used by other routing protocols in addition to BGP? (Choose all that apply.)

Accepted Answer

The answer of Which of the following route selection tools...

Question 15

Which of the following statements regarding preemption in static LACP mode are true? (Choose all that apply.)

Accepted Answer

When a high-priority interface switches to the inactive interface due to a fault and then is restored, if preemption is enabled, the restored high-priority interface becomes the active interface after a delay. If preemption is disabled, the interface cannot become the active interface. To prevent unstable transmission due to frequent link status changes, can set a preemption delay. If the preemption delays at both ends are different, the larger preemption delay is used.

Question 16

Which of the following statements regarding LACP are true? (Choose all that apply.)

Accepted Answer

LACP (Link Aggregation Control Protocol) uses LACPDUs to exchange information between devices. The active side is determined by the LACP system priority and system ID.

Question 17

For label switched packets that contain the same source and destination address and are transmitted via the same interface, the label switch path 0

Accepted Answer

The answer of For label switched packets that contain the...

Question 18

Which of the following statements regarding BGP message types and characteristics is false?

Accepted Answer

Route-refresh messages are used to request a complete routing table from a peer, not to notify the peer that the device has the route refresh capability.

Question 19

BGP is an enhanced distance-vector routing protocol. Which is the major reason for this?

Accepted Answer

BGP is considered an enhanced distance-vector protocol because it uses the AS_Path attribute to record all ASs a route passes through, and prefers routes with shorter AS_Paths, which helps prevent routing loops and ensures efficient path selection.

Question 20

Which of the following statements regarding routing policy and policy-based routing are true? (Choose all that apply.)

Accepted Answer

Policy-based routing allows for packet forwarding decisions based on policies rather than the routing table. A routing policy manages the import, advertisement, and reception of routing information.
