Question 1

In the OSPF protocol for wide area networks, what is the main difference between an "NSSA area" and a "normal Stub area"?

A. NSSA areas do not receive Type 3 LSA, while regular Stub areas do.

B. NSSA areas allow the introduction of external routes from the AS (Type 7 LSA), while regular Stub areas do not.

C. The NSSA region is no different from a regular Stub region; only the configuration commands differ.

D. NSSA areas only receive Type 1/2 LSAs, while regular Stub areas receive Type 1/2/3 LSAs.

Correct Answer: B

Question 2

In the deployment of the OSPF protocol in a wide area network, what is the core function of the
"Stub area"?

A. Achieve indirect connection between non-backbone regions and Area 0.

B. Allow the advertising of Type 5 LSAs (AS external routes) within the area.

C. Prohibit the publication of Type 5 LSAs within the area, only allow Type 3 LSAs (inter-area summary routes), and reduce the number of route entries.

D. Disable OSPF authentication and simplify the configuration process.

Correct Answer: C

Question 3

In Huawei's SD-WAN solution, for the scenario of " sudden branch link failure", which of the following technologies can "detect the failure in milliseconds and automatically switch to the backup link to ensure uninterrupted service"?

A. Manually switch links after a fault is detected manually.

B. Switchover is triggered based on the default timeout of the routing protocol (e.g., OSPF dead timeout of 40 seconds).

C. Using only a single link, with no backup link.

D. BFD (Bidirectional Forwarding Detection) + Automatic Link Switching Mechanism

Correct Answer: D

Question 4

In an MPLS VPN network, which type of device is responsible for "connecting the customer network and the operator's backbone network to achieve VPN route access and forwarding"?

A. CE Equipment (Customer Edge)

B. PE device (Provider Edge)

C. P device (Provider)

D. Core Router

Correct Answer: B

Question 5

In an MPLS VPN network, which of the following descriptions conforms to the forwarding logic of
"public network label (outer label)"?

A. Assigned by the P device according to the routing table, used for backbone network forwarding path identification.

B. Assigned by the PE device according to the MPLS LDP protocol, for forwarding between P devices.

C. Assigned by the CE device to identify the VPN service type.

D. Assigned by the PE device to identify the VPN instance to which the data packet belongs.

Correct Answer: B

Question 6

In Huawei's SD-WAN solution, which of the following functions can "classify branch service traffic and allocate different bandwidth ratios to different services (such as ERP and video)"?

A. Automatic link switching

B. IPsec encrypted tunnel

C. Link Quality Detection (LQM)

D. Business Traffic Classification and Bandwidth Allocation

Correct Answer: D

Question 7

In the OSPF protocol for wide area networks, which of the following is the generator of a Type 2 LSA (Network LSA)?

A. Area Border Router (ABR)

B. DR (Designated Router) within the area

C. Autonomous System Border Router (ASBR)

D. All routers within the area

Correct Answer: B

Question 8

In the WAN BGP protocol, if "route reflectors are configured between IBGP neighbors, but no clients are configured for the reflectors", which of the following problems will this cause?

A. The route reflector automatically treats all neighbors as clients, reflecting routes normally.

B. IBGP neighbor relationships cannot be established.

C. The route reflector cannot pass reflected routes to non-client neighbors.

D. The route reflector cannot receive routes from the client's neighbors.

Correct Answer: C

Question 9

In Huawei's SD-WAN solution, which of the following functions can "statistically calculate the bandwidth usage ratio of VPN services and public network services for each branch device and generate a visual report"?

A. Equipment hardware resource monitoring

B. Link Quality Detection (LQM)

C. IPsec tunnel status monitoring

D. Service Traffic Bandwidth Statistics and Reports

Correct Answer: D

Question 10

In a wide area network (WAN) BGP protocol deployment, which of the following configurations can "prevent unauthorized devices from forging BGP neighbor access to the network and improve security"?

A. Disable BGP anti-loop mechanism

B. Enable BGP Neighbor MD5 Key Authentication

C. Configure BGP route aggregation

D. Adjust BGP route priority

Correct Answer: B
