Question 1

Fast detection technology can rapidly detect communication faults between neighboring devices as soon as possible so that the system can take measures immediately to ensure that services are not interrupted.

Accepted Answer

Fast detection technology is designed to quickly identify faults in communication between devices, allowing for immediate corrective actions to maintain uninterrupted services.

Question 2

Congestion management uses queue scheduling to manage and control traffic when traffic congestion occurs.

Accepted Answer

Queue scheduling is a technique used in congestion management to prioritize and manage data packets, helping to control traffic flow during congestion.

Question 3

Which of the following statements regarding different LSA types is false?

Accepted Answer

LS Ack packets do not contain complete LSA information; they only acknowledge the receipt of LSAs by listing their headers.

Question 6

During the structured network troubleshooting process, in which of the following phases is the fault reported or advertised to other departments? (Choose two.)

Accepted Answer

The answer of During the structured network troubleshooting process, in...

Question 7

To prevent inter-area routing loops, OSPF does not allow advertising routing information between two non-backbone areas and allows advertising routing information only within an area or between the backbone area and a non-backbone area. Therefore, each ABR must be connected to the backbone area.

Accepted Answer

OSPF requires that all non-backbone areas connect to the backbone area (Area 0) to ensure proper routing and prevent loops, as the backbone area acts as a central hub for inter-area communication.

Question 8

If Router Priority is set to 0 for a router, it is allowed to elect this router as a DR or BDR in an OSPF routing domain, but its priority is the lowest.

Accepted Answer

If Router Priority is set to 0 in OSPF, the router is not eligible to become a Designated Router (DR) or Backup Designated Router (BDR).

Question 9

An AS boundary router can be an internal router or ABR and must belong to the backbone area.

Accepted Answer

An AS boundary router is a router that connects two or more autonomous systems. It must belong to the backbone area, which is the area that connects all other areas in the AS.

Question 10

Which of the following statements regarding the transit node in the MPLS forwarding process is correct?

Accepted Answer

The transit node in MPLS uses the NHLFE entry to determine the outbound interface, next hop, outgoing label, and label operation type for forwarding packets.

Question 11

MPLS supports multi-layer labels and connection-oriented on the forwarding plane, therefore it is widely used. So, which of the following is not the cause for MPLS deployment?

Accepted Answer

MPLS is not primarily deployed to simplify route queries on software-based routers. Its main benefits are traffic engineering, VPN services, and vendor support.

Question 12

Which of the following statements regarding the failure to establish a BGP peer relationship is false?

Accepted Answer

The default TTL for EBGP Update messages is 1, not 2, and it can be manually modified to establish a connection with indirectly connected peers.

Question 13

Which of the following are possible causes for an MSTP failure in a LAN? (Choose three.)

Accepted Answer

MSTP is configured incorrectly, a physical link alternates between Up and Down, triggering the device to send a large number of TC packets, and the MSTP-enabled device receives MSTP TC packets that are transparently sent or from the client can all cause an MSTP failure in a LAN.
