The OSPF protocol is deployed in a small and medium-sized network. When checking the routing table of a certain device, it is found that only direct routes exist.
Which of the following operations is unlikely to cause this fault?
- A . Routing protocol configuration error
- B . The configured user permissions are too low
- C . Routing policy configuration is wrong
- D . Port address configuration problem
A router has the SRv6 function enabled and is configured as shown in the figure. Which of the following descriptions of this configuration are correct? (Multiple choice)
[Router-seement-routing-ipv6] locator srv6 locator1 ipv6-prefix 2001:DB8: ABCD: : 64 static 32
- A . The 1ocator of this node is 2001: DB8: ABCD::
- B . The args field of this node occupies 32 bits
- C . The static segment of this node occupies 32 bits
- D . The dynamic segment of this node occupies 32 bits
As shown in the figure, PE1 and PE2 exchange private network routing information with their respective CEs through OSPF, and the same Domain ID is configured on both PE1 and PE2.
When importing routes from BGP to OSPF on PE2, which of the following types of LSAs may be passed to CE2? (Multiple choice)
- A . Type7 LSA
- B . Type3 LSA
- C . Type1 LSA
- D . Type5 LSA
Traffic policing can only be used in the inbound direction. Its function is to monitor the traffic entering the device to ensure that the upstream device does not abuse network resources.
- A . True
- B . False
As shown in the figure, PE1 establishes EVPN adjacencies with PE2 and PE3 respectively. When the network is initialized, CE1 sends an ARP request message. Which of the following descriptions of how PE handles this message are correct? (Multiple choice)
- A . PE3 will forward the packet to CE1
- B . When PE1 forwards the packet to PE3, it needs to add the BUM traffic label assigned by PE3.
- C . PE2 will forward the packet to CE1
- D . PE1 will send a MAC/IP Advertisement Route carrying the MAC address of CE1
Considering the transformation cost, technological advancement and transformation impact scope, which of the following principles should be followed during IPv6 transformation? (Multiple choice)
- A . Choose an appropriate IPv6 upgrade and evolution plan from a global perspective, rationally reuse old materials, and avoid asset waste.
- B . Deploy a dual-stack network to achieve long-term coexistence of IPv4 and IPv6 networks
- C . Build an advanced next-generation enterprise IPv6 network system architecture to fully support the long-term development and stable operation of enterprise business systems and avoid network reconstruction and duplication of investment.
- D . Ensure that existing users are unaware and business migration is smooth
iMaster NCE-Campus imposes certain restrictions on the headers of the RESTful interface. When the client calls the RESTfu interface to send a TP" request message to iMaster NCB-Campus, which of the following parameters do the headers mainly include? (Multiple choice)
- A . X-ACCESS-TOKEN: Token information
- B . Accept-Language: The language type acceptable to the client defaults to en-US
- C . Content-Type: Contains the "mime-type" of the document. The browser will use this parameter to decide how to parse the document.
- D . Accept: Indicates the MIME types acceptable to the browser. The browser will decide which parameter format to accept based on this parameter
Which of the following descriptions of the SP scheduling algorithm is wrong?
- A . The SP scheduling algorithm prioritizes scheduling of high-priority queues.
- B . When using the SP scheduling algorithm, if high priority occupies a large amount of bandwidth, it may cause starvation of the low priority queue.
- C . When using the SP scheduling algorithm to schedule multiple low-priority queues, the data packet that enters the queue first will be forwarded first.
- D . In order to ensure the quality of key services, the services can be scheduled through the SP algorithm. and set the minimum bandwidth
