TRUE

False

NO.107 After you divide an interface of the firewall into the Untrust security domain, the interface belongs to the Untrust zone and no longer belongs to the Local zone.

TRUE

FALSE

NO.108 HW users are transferring a very large number of files via TFTP. What protocol does TFTP rely on for transmission?

ICMP and UDP

IP ?TCP

UDP

NFS

FTP

NO.109 As shown in the topology diagram, all interfaces of the router in the figure are enabled with the ISIS protocol, and the following statement is correct.

If the RI’s Ethernet0/0/0 interface goes down, R2 becomes the master device

If the Ri’s Ethernet0/0/1 interface goes down, R2 becomes the master device

If R3’s G E0/0/0 interface goes down, R2 becomes the master device

If R3’s Ethernet0/0/0 interface goes down, then R2 becomes the master device

NO.110 BGP EVPN does MAC address advertisement, ARP message advertisement, and IRB route advertisement for which BGP EVPN route is advertised?

Type3

Type2

Type4

Type1

NO.111 Regarding the Stub region and the Totally Stub region of the OSPF protocol, the following statement is correct (multiple choice)

After modifying the original Stub area to a Totally Stub area, the number of LSAs in the LSDB of each router in the region will definitely be reduced

ASBR cannot be present in either the Stub zone or the Totally Stub zone

When you modify the original Stub area to a Totally Stub region, the number of LSAs propagating within the region will definitely decrease

If there are two ABR in the Totally Stub zone, each ABR sends an LS ID of 0000 to the router in the zone LSA

NO.112 Firewall security policies have the condition for traffic matching to be ?( Multi-select)

apply

Source item security zone

Source item IP address

Message length

NO.113 What designs in the router can improve the reliability of the router?

Dual power supply design

Module hot-swappable design

Issu Design

Dual-engine design

NO.114 As shown in the figure, the overload bit of ISIS is set in the configuration of router R3, and the following statement is correct

R3’s direct route will be ignored by R1 and R2 because of the setting of the overload bit .

When the router runs out of memory, the system automatically sets the overload flag bit in the sent LSP packets.

Irrelevant to whether the user has a set-overload command configured.

Routes introduced by R3 through import-route will not be published. The LSP of R3 will not be able to spread to R1 and R2

R3 initiates the load state, and R1 and RZ will not calculate the LSP of R3 cattle in the SP tree.

NO.115 The switch can suppress traffic by suppressing traffic and extremely other failures can affect operations, which of the following traffic suppression configurations is the wrong configuration

[Quidway] wan 10 [Quidway-wan10] multicast-suppression 1000 [Quidway-van10] quit

NO.118

When sending a packet with a destination address of 4444, it is sent without labeling.

When the router receives a packet with the label 1024, it replaces the label with 1027 and sends it.

When a packet with a destination address of 2 is sent , it is sent without labeling.

When sending a packet with a destination address of 3333, label 1026 and send it.

NO.119 There is an existing router interface serial 0 in OSPF area 1 , well will interface Serial 0 is set to silent interface. So what is the impact of this setting?

OSPF establishes usable adjacencies through this junction

OSPF does not join the routes learned from the connector to the local routing table

OSPF does not establish any adjacency relationships through the junction

OSPF receives a route update answer from the neighbor.

NO.120 IGMP SSMMapping is bound to multicast through a static multicast source, so that members of IGMPv1 and IGMP2 can also access the SSM multicast network. The following statement about IGMPSSMMapping is wrong?( Radio).

The multicast address of the SSM is 23

IGMP SSM Mapping does not process reporting messages from IGMPv3 In order to ensure that the same network segment runs any version

IGMP hosts can make SSM services run IGMPv3 on the multicast router socket connected to the network segment where the member host is located

If the IGMP SSM Mapping feature is not enabled, neither IGMPv1 nor IGMPv2 supports multicast for deploying SSM modules
