As shown in the figure, the network administrator deploys the DHCP Snooping function on the switch to defend against attacks by DHCP Server impersonators. Which of the following interfaces should be set as a DHCP trusted interface?
- A . GE0/0/2
- B . GE0/0/3
- C . GE0/0/1
- D . GE0/0/4
In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The Router ID of each device is 10.0.XX, and the AS number is 6500X, where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are introduced into BGP through import. R1 adds the Community attribute value (1:1) when sending routes to its neighbors. All routers in the network are enabled to pass community attributes. Which of the following can make the traffic path from R3 to 192.168.1.0/24 must pass through R4?
- A . Configure a routing policy on R5 to reject routes with a community attribute value of 1:1.
- B . Configure a routing policy on R2 to reject routes with a community attribute value of 1:1.
- C . Configure a routing policy on R4 to reject routes with a community attribute value of 1:1.
- D . Configure a routing policy on R3 to reject routes with a community attribute value of 1:1.
Port security is achieved by converting the dynamic MAC address learned by the interface into a secure MAC address, including secure dynamic MAC, secure static MAC and sticky MAC. Which of the following descriptions about secure MAC addresses are correct? (Multiple choice)
- A . If you manually save the configuration and restart the device, the secure static IAC address information will be lost
- B . The difference between secure dynamic MAC and sticky MAC is that the MAC table entry of the former will be lost after the device is restarted.
- C . By default, these three types of MAC address information will not be aged.
- D . Port Secure Dynamic MAC and Sticky MAC both convert dynamically learned MAC addresses into secure addresses
The path that IP packets pass through in the MPLS network is called the label switched path LSP. LSP is a bidirectional path that indicates the direction of data flow transmission.
- A . True
- B . False
An enterprise network is shown in the figure. If CE2 is dual-owned by PE2 and PE3, a Type 3 LSA routing loop may occur. The loop can be prevented by setting the dn-bit-set disable command on PE2 and PE3 devices.
- A . True
- B . False
MPLS supports multi-layer label nesting. When the device receives an MPLS message, it will first process the label close to the second-layer header, that is, the MPLS label at the top of the stack.
- A . True
- B . False
In the Hub&Spoke network shown in the figure, in order to achieve correct routing transmission, the administrator must manually configure the command peer 10.1.2.1() in the BGP-VPN_out view of the Hub-PE.
Network engineers can determine whether the link connection is normal by observing the interface indicators of the NetEngine AR6120 on site, but cannot determine whether the interface is configured with an IP address.
- A . True
- B . False
A network engineer enters "dir" on the device and obtains the following file names. Which of the following is most likely to be the version file of the device?
- A . V300R022000SPC100.cfg
- B . startup yl.rdb
- C . Ca.cer
- D . V300R022C00SPC100.cc
In a BGP/MPLS IP VPN network, when a PE device advertises VPNv4 routes, which of the following information will it carry? (Multiple choice)
- A . IPv4 address prefix
- B . export Target
- C . Import Target
- D . RD
