H12-721 Huawei Certified ICT Professional - Constructing Infrastructure of Security Network Question and Answers

If the file server type is NFS, the user UID and GID attributes do not allow the user to upload, delete, or rename files.

If the type of the file server is SMB, the currently logged-in user has only read permission for the file share resource, but no write permission.

Only the viewing function is enabled in the SSL file sharing function configuration of the C firewall.

Some TCP connections between the virtual gateways of the D file server are blocked by the firewall

IP address scanning attack is an attacker that uses an ICMP packet (such as ping and tracert) to detect the target address.

IP address scanning attack is an attack method used by an attacker to detect a target address by using TCP/UDP packets.

IP address scanning attack defense detects the rate of address scanning behavior of a host. If the rate exceeds the threshold, it is blacklisted.

If the USG starts the blacklist function and is associated with IP address scanning attack prevention, when the scanning rate of a certain source exceeds the set threshold, the excess threshold will be discarded, and the packets sent by this source will be less than the subsequent time. Threshold, can also be forwarded

connected user's firewall interface is configured in trusted mode

The firewall interface connected to the DHCP server is configured as untrusted mode.

DHCP relay packets received on the interface in the untrusted mode are discarded.

The DHCP relay packet received in the D trusted mode and passed the DHCP snooping check.

All negotiation packets in the first phase of the aggressive mode are encrypted.

All the negotiation packets of the first phase in the main mode are encrypted.

barbarian mode uses DH algorithm

will enter the fast mode regardless of whether the negotiation is successful or not.

is used for detection of IKE neighbor status

PDUs are sent periodically between B IKE PEERs.

After the DPD function is enabled, the IPSec packet is not received within the interval specified by the interval, and the DPD sends a DPD request to the peer and waits for the response. Text

DPD sends the query only before the encrypted message is sent and the timer expires.

L2TP protocol uses the TCP protocol

supports private address allocation and does not occupy public IP addresses.

and PPP configurations support authentication and work with Radius to support flexible local and remote AAA After combining with IPSec,

supports encryption of packets.

local ike policy does not match the peer ike policy.

local ike remote namet and peer ikename do not match

local ipsec proposal does not match the peer ipsec proposal.

The local security acl or the peer security acl does not match.

Configure the nat policy. The reference rule is to allow the source and destination of the intranet to be all ACLs.

Configure the IKE peer, use the name authentication, and remote-address is the outbound interface address of the headquarters.
