3. There is an existing router HW1 running OSPF. The interface Sera0 of HW1 is released in area 0, and the interface Sera1 is released in area 1. Run the "nssa default-route-advertise" command in the OSPF process.
Based on the previous description, which of the following options are inferred to be correct? (Multiple choice)

HW1 will inject zone 3 default routes into zone 1.

HW1 will inject zone 7 default route into zone 1.

HW1 will inject zone 7 default route into zone 0

When HW1 injects the default route into Area 1, the local routing table of HW1 needs to have a default route.

When HW1 injects the default route into Area 1, the local routing table of HW1 may not contain a default route.

Smart-link can be mixed with STP under the interface.

Smart-link supports load sharing.

Smart-link mainly includes two roles: primary port and slave port.

Smart-link cannot detect the uplink and downlink status.

Question 9 of 20

10. Command ip ip-prefix ip-prefix-name [index index-number] { permit | deny} ipv4-address mask-length [greater-equal greater-equal-value ] less-equal less-equal-value]Hf-IP- Prefix-filter.
If the less-equal of a prefix list has been specified, but the greater-equal is not specified, what is the range of the prefix?

[0,less-equal-value

mask-length, less-equal-value

[less-equal-value, 32

No restrictions

Question 10 of 20

11. Use the ip as-path-filter as-path-filter-number {deny | permit} regular-expression command to configure the as-path filter.
In this command, multiple clauses can form an as-path-filter statement.
So what is the relationship between multiple statements?

Relationship with

Relationship or

The routes are matched in order. When a route matches a clause, it no longer matches downwards.

The routes are matched in order and the route needs to match all the clauses.

The main is UDP traffic in the network.

The main is TCP traffic in the network.

Deploy on low bandwidth links.

Deploy on a serial link.

WRED randomly drops packets, the effect is not related to the scene.

Question 13 of 20

14. When there are multiple matching rules in the ACL of the VRP, which of the following statements is correct about the matching order?

By default, match according to rule-id, from small to large

By default, match the permit first and deny later.

By default, match according to the principle of “depth first”

There is only one matching order and cannot be modified

Question 14 of 20

15. What benefits can be achieved after using WRED? (Multiple Choice)

Thoroughly avoid congestion

Avoid TCP global synchronization

Provide minimum bandwidth guarantee

Provide a certain low latency

Can avoid UDP taking up most of the bandwidth when it is congested

Question 15 of 20

16. The order for the protocols using TCP ports 443, 179, 137, 110, and 23 is:

BGP, POP3, SNMP, TFTP, Telnet

Question 16 of 20

17. In Huawei device, when ISIS imports external routes and sets external route tags for routing information, the ISIS metric type does not need to be modified to keep the default.

True

False

Question 17 of 20

18. Which of the following is correct about the ISIS LSP fragmentation extension?

Enable the ISIS router to generate more LSP fragments to carry more ISIS information.

ISIS fragmentation extensions are equally valid for Hello packets.

ISIS fragmentation extensions are achieved by adding virtual systems, which can be expanded to a maximum of 1000 virtual systems.

The maximum number of fragments that an ISIS router can generate is 1024.

Question 18 of 20

19. User wants to enable the router for packets forwarding and routing according to the policy defined by itself based on the traditional route forwarding.
To achieve this goal, policy routing can be employed.
Which of the following about the description of policy routing is wrong?

Policy routing cannot be used to set IP Precedence

Policy routing cannot set DSCP in a statement

Policy routing can set the next hop IP address

Policy routing can be used to match the packet length

Question 19 of 20

20. Which of the following is the correct description of OSPF adjacency and link state database synchronization?

When the state of the OSPF router reaches the LOADING state, the FULL adjacency is formed.

The adjacency relationship starts from the EXSTART state.

FULL adjacencies are formed between all routers in the broadcast network.

The INT status indicates that the router has received a Hello packet from the neighbor and the Hello packet already contains its own router ID.
