QUESTION 55
When OSPF is deployed on a wide area network (such as an inter-carrier link), which of the following configurations can improve the adaptability and stability of the OSPF network? (Multiple choice)

Adjust OSPF hello/dead times (e.g., change the hello time to 30 seconds to adapt to high latency in wide area networks).

Enable OSPF authentication (such as zone authentication to prevent fake LSA injection).

Divide OSPF into reasonable areas (e.g., divide cross-regional links into backbone areas Area 0).

Using the default hello/dead times (10s/40s) is not suitable for wide area network latency.

Without configuring OSPF authentication, any device can access the OSPF domain .

Check if the MPLS LSP between PE devices is established.

Check the BGP protocol configuration on the P device.

Check if the BGP version of the CE device is consistent with that of the PE device.

Link bandwidth statistics report

Link quality monitoring and threshold alarms

Equipment hardware resource monitoring

Configure compliance checks

QUESTION 67
In an MPLS VPN network, which of the following operations can “ensure that the PE device correctly imports the routes learned from the CE device into the BGP VPNv4 address family”?

Configure routing policies on the PE device to import CE routes into the BGP VPNv4 address family.

Configure a route import policy on the P device to pass CE routes to BGP.

Configure the BGP protocol on the CE device to directly advertise the VPNv4 address family to the PE.

No configuration is required; the PE device automatically imports the CE route to BGP VPNv4.

QUESTION 68
In Huawei’s wide area network solution, for “video-on-demand (VOD) traffic transmitted across regions”, which of the following technologies can “achieve localized distribution of video content and reduce user access latency”?

All video content is transmitted directly from the headquarters video server and is not distributed.

Deployment of a video content edge distribution network (CDN) (caching popular videos on nodes near branches)

Reduce the video content bitrate, sacrificing clarity for lower latency.

Limit the number of simultaneous video requests by users to avoid network congestion.

QUESTION 69
In Huawei’s WAN bandwidth optimization solution, for “real-time collaboration tool traffic transmitted across regions (such as Teams, Zoom),” which of the following technologies can
“ensure the smoothness of real-time voice/video and reduce lag”?

Transmit traffic directly without any optimization.

Application protocol-based acceleration technologies (such as optimizing the Real-time Transport Protocol, RTP)

Limit real-time bandwidth and prioritize file transfer.

All real-time traffic is relayed through headquarters, increasing latency.

QUESTION 70
(Which of the following statements isfalseabout sites on a virtualized network deployed using iMaster NCE- Campus?)

iMaster NCE-Campus does not support batch site creation.

Tenants configure and manage devices by site.

iMaster NCE-Campus allows administrators to create sites one by one.

A site is a tenant network created by a tenant administrator.

QUESTION 71
In the OSPF protocol for wide area networks, what is the main difference between a “full stub area” and a “normal stub area”?

Fully stub areas do not receive Type 3 LSAs (Inter-area summary routes), while regular stub areas do.

Fully stub areas receive Type 5 LSAs (AS external routes), while ordinary stub areas do not.

Fully stub regions receive only Type 1/2 LSAs, while ordinary stub regions receive Type 1/2/3 LSAs.

A fully stub region is no different from a regular stub region, only the configuration is different.

QUESTION 76
(Which of the following statements about configuring user access authentication is false?)

To implement network access control on users, you need to determine the domains to which they belong and the AAA schemes that they use.

You need to bind an access profile to an authentication profile to specify the user authentication mode.
Then, apply the authentication profile to an interface or VAP profile to enable network access control.

iMaster NCE-Campus cannot interconnect with a third-party RADIUS server.

If the RADIUS or HWTACACS server is used for authentication, you need to configure parameters for interconnection with the authentication server in the AAA scheme.
