NEW QUESTION 163
A network connection is like:
HostA—-GE0/0–MSR-1–S1/0———S1/0–MSR-2–GE0/0—-HostB
Two MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their S1/0 interfaces, and their GE0/0 interfaces are respectively connected to the client hosts HostA and HostB. The IP address of HostA is 192.168.0.2/24, and the address of the S0/0 interface of MSR-2 is 1.1.1.2/30. By configuring other relevant IP addresses and routes, HostA can communicate with HostB in the current network.
Nowadays, the customer requires that HostA is not allowed to log in to the MSR-2 through Telnet at address 1.1.1.2.
So which of the following configurations can meet this requirement? (multiple choice)

Configure the following ACL on MSR-1 and apply it to the inbound direction of GE0/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl-adv -3000]rule 0 deny tcp source 192.168.0.1 0.0.0.255 destination 1.1.1.2 0.0.0.3 destination-port eq telnet

Configure the following ACL on MSR-1 and apply it to the outbound direction of GE0/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl- adv-3000]rule 0 deny tcp source 192.168.0.2 0 destination 1.1.1.2 0 destination-port eq telnet

Configure the following ACL on MSR-1 and apply it to the inbound direction of S1/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl- adv-3000]rule 0 deny tcp source 192.168.0.1 0.0.0.255 destination 1.1.1.2 0 destination-port eq telnet

Configure the following ACL on MSR-1 and apply it to the outbound direction of S1/0 of MSR-1: [MSR-1]firewall enable [MSR-1]acl number 3000 [MSR-1-acl- adv-3000]rule 0 deny tcp source 192.168.0.2 0 destination 1.1.1.2 0.0.0.3 destination-port eq telnet

NEW QUESTION 164
The correct statement below is ______. (Multiple choice)

MSTP and RSTP can identify each other’s protocol packets and are compatible with each other

In STP compatibility mode, each port of the device will send out STP BPDU packets

In RSTP mode, each port of the device will send out RSTP BPDU packets. When it is found to be connected to an STP device, the port will automatically migrate to work in STP compatibility mode

In MSTP mode, each port of the device will send out MSTP BPDU packets. When a port is found to be connected to an STP device, the port will automatically migrate to work in STP compatibility mode

NEW QUESTION 165
The PC is connected to the port E1/0/2 of the switch SWA, the IP address is 10.1.1.1, and the MAC address is 00-01-02-01-21-23. To ensure network security, you need to configure MAC+IP+ port binding on port E1/0/2.
Which of the following commands is correct?

[SWA] user-bind ip-address 10.1.1.1

[SWA-Ethernet1/0/2]user-bind ip-address 10.1.1.1

[SWA] user-bind ip-address 10.1.1.1 mac-address 0001-0201-2123

[SWA-Ethernet1/0/2]user-bind ip-address 10.1.1.1 mac-address 0001-0201-2123

NEW QUESTION 166
TCP belongs to the ______ of the OSI reference model.

NEW QUESTION 167
The two MSR routers are interconnected through their respective WAN interface S1/0, and RIPv2 is running on the two routers to dynamically complete the remote routing of each other. Now for security reasons, it is necessary to add verification on the RIP, so which of the following Is the RIP configuration correct?

[MSR-serial1/0]rip authentication-mode simple 123

[MSR]rip authentication-mode simple 123

[MSR-rip-1] rip authentication-mode simple 123

[MSR-rip-2]rip authentication-mode simple 123

NEW QUESTION 168
The following statement about the upgrade of H3C network equipment is correct ______. (Multiple choice)

Use Xmodem to upgrade to the same speed as FTP

When using FTP to upgrade, the device can only be used as an FTP client

When the device cannot boot to the command line mode and needs to upgrade the operating system software, only the Xmodem method can be used

In an environment where the complex interaction between the client and the server is not convenient, you can use TFTP to upgrade

NEW QUESTION 169
