A medium-sized campus network manages the network through the SNMP protocol. The campus has high network security.
Which SNMP version is recommended for management?
- A . SNMPv1
- B . SNMPv2C
- C . SNMPv3
- D . All versions can be implemented
In a VXLAN network, which can realize traffic access to the VXLAN network, and can also be used for communication with the same subnet in the same XLAN network?
- A . NVE interface
- B . VXVAN L2 Gateway
- C . VXLAN L3 Gateway
- D . VLANIF interface
What are the problems with manually creating static VXLAN tunnels in a campus network? (Multiple Choice)
- A . Although the static VXLAN tunnel mode can support distributed gateway application scenarios, the configuration workload is large and the configuration adjustment is complicated.
- B . When N devices establish static VXLAN tunnels, at most N (N-1)/2 tunnels need to be manually configured, and the amount of configuration is large.
- C . VTEP can only rely on data flooding to learn the remote MAC address
- D . Static VLAN tunnels also use related protocols on the control plane, which will cause device resource consumption
The DHCP protocol can assign some TCP/IP-related parameter information to the client. In this process, DHCP defines a variety of packets. The encapsulation protocol used by these packets at the transport layer is:
- A . PPP encapsulation
- B . IP encapsulation
- C . TCP encapsulation
- D . UDP encapsulation
After a switch is powered on, it joins a running stack system. This behavior is called stack join.
- A . TRUE
- B . FALSE
In the multi-level RR scenario, a large number of secondary RRs will be connected to the primary RR, which may cause the BGP routing table of the primary RR to overflow.
What method can be used to reduce the risk of overflowing the the primary RR BGP routing table?
- A . ORF
- B . Routing Control
- C . Route Aggregation
- D . Set the same Cluster-ID
In BGP4+, what is the content of the next hop network address field carried by the MIP_REACH_NLRI attribute in the Update packet?
- A . Can be just a link-local address
- B . Only link-local addresses
- C . Can carry link-local addresses and global unicast addresses at the same time
- D . Can only be a global unicast address
The following descriptions about Link ID, Data, Type and Metirc in Router-LSA, which are correct? (Multiple Choice)
- A . Metric describes the cost of this connection
- B . Link ID indicates the local identification of this connection, and different connection types indicate different meanings of Link ID
- C . Data is used to describe the additional information of this connection, and the information described by different connection types is also different
- D . Type indicates the type of connection
Which of the following statements about the IS-IS protocol is false?
- A . IS-IS protocol is a link state protocol that runs between ASs
- B . IS-IS protocol supports CLNP network
- C . IS-IS protocol packets are directly encapsulated by the data link layer
- D . IS-IS protocol supports IP network
BGP authentication can prevent illegal routers from establishing neighbors with BGP routers. BGP authentication can be divided into MD5 authentication and Keychain authentication.
Which of the following BGP packets will carry BGP Keychain authentication information? (Multiple Choice)
- A . Update
- B . Notification
- C . Keeplive
- D . Open
