- A . Deploy overlay to access the resource pool
- B . Deploy Fabric global resource pool
- C . Deploy Underlay automated resource pool

As shown in the figure, Site1 and Site2 need to achieve mutual access through the operator’s BGP/MPLSIPVPN. It is known that the public network tunnel between PE1 and PE2 has been established (the label information is as shown in the figure), and PE1 has set 192.168 in Site1. The route of network segment 1.0/24 is advertised to PE2 through the MP-IBGP neighbor relationship, and route learning is normal.

When crawling Site2 to access the 192.168.1.0/24 data of Site1 between P and PE1, which of the following is the outermost label?
- A . 3
- B . 8888
- C . 6662
- D . 6661
The rules of route advertisement by RR violate the rules of IBGP split horizon, so it may cause loops in the AS. What routing attributes does RR use to prevent loops? (Multiple choice)
- A . Cluster List
- B . Nexthop
- C . AS-PATH
- D . Originator ID
Part of the configuration of the switch is shown in the figure.

Which of the following descriptions of the configuration on this switch are correct? (Multiple choice)
- A . First you need to create a DHCP server group and add a DHCP server to the server group
- B . To configure both the DHCP server and DHCP Delay, DHCP must be enabled globally.
- C . The VLANIF 100 interface will send the received DHCP messages to the external DHCP Server through relays
- D . Specify the DHCP server group for VLANIF 100 interface as dhcpgroup 1
The network administrator wants to use the IP Prefix List to match specific routing entries. Which of the following routing entries will be matched by the IP Prefix List in the figure? (Multiple choice)
![]()
- A . 10.0.1.0/24
- B . 10.0.0.1/30
- C . 10.0.2.0/24
- D . 10.0.0.0/24
HTTP Status Code (HTTP Status Code) is a 3-digit code of the server response status, which is used to return the operation result to the client. Please match the HTTP status code with the reason phrase.

There is a Linux SSH server in the current network. The network administrator uses his own PC SSH to log in to the server for the first time and receives the following information. Which items in the following description are correct? (Multiple choice)
- A . You can skip this prompt message through the SSH method in the Python Paramiko library, set_missing_host_key_policy(WarningPolicy())
- B . The client does not save the private key of the Linux server
- C . You can skip this prompt message through the SSH method in the Python Paramiko library, set_missing_host_key_policy (AutoAddPolicy ())
- D . The client does not save the public key of the Linux server
The output information of a certain router is as shown in the figure. Which item is wrong in the following description?

- A . This tunnel is a GRE tunnel
- B . This tunnel enables key sub-checking function
- C . The tunnel has the Keeplieve check function enabled.
- D . The destination address of the tunnel is 10.0.3.3
Engineers need to download the device configuration file vrpcfg.cfg locally through SFTP, then rename the configuration file to backup.cfg and re-upload it to the device’s default directory. It is known that the configuration file path of the device is /vrpcfg.cfg, which is located in the default directory / of the device.
The engineer’s local file path is C:. Which of the following Python Paramiko codes can achieve the above function?
- A . sftp.get(‘/vrpcfg.cfg’, r’C:backup.cfg’) sftp.put(r’C:backup.cfg’, ‘/backup.cfg’)
- B . sftp.get(r’C:backup.cfg’,’/vrpcfg.cfg’) sftp.put(‘/backup.cfg,r’
- C . :backup.cfg’) C.sftp.get(‘/vrpcfg.cfg’, r’C:vrpcfg.cfg’) sftp.put(‘/backup.cfg’, r’C:vrpcfg. cfg’)
- D . sftp.get(‘/vrpcfg.cfg’, r’C:’) sftp.put(r’C:backup.cfg’, ‘/’)
In the scenario of dynamically establishing a VXLAN tunnel through BCP EVPN, when using BGP EVPN Type2 routing for host MAC address advertisement, which of the following descriptions is correct?
- A . It will carry specific L2 VNI and L3 VNI values at the same time.
- B . Will carry specific L3 VNI value
- C . The RT value carried is the Export RT in the IP VPN instance.
