Best H12-891_V1.0 Exam Dumps for the Preparation of Latest H12-891_V1.0 Exam Questions [Q221-Q240]

Q221. Which of the following descriptions of MPLS header TTL are correct?

Copy IPTIL value is handled in such a way that the LSR of the MPLS domain is hidden, which plays a certain security role

Can prevent wireless circular forwarding of messages

MPLS has two ways of handling TTL, one is that the IP packet copies the PTTL of the MPLS header hen it enters the MPLS network Value; Another is to set the TTL of the MPLS header to 255 at the entrance LER

When copying TTL is disabled, tracert can see the LSR of the passing MPLS domain

Q222. Regarding the BGP ring protection mechanism, is the following description correct?

The AS_ PATH attribute is used between autonomous systems to prevent ring cats

The Cluster List property is used for loop guard within the reflector cluster, and the router rejects the route when it finds that the Cluster List of the route entry contains its own Cluster ID.

Routes learned from IBGP are not advertised to IBGP neighbors and are used to prevent routing loops inside the AS.

You can use the AS_ CONFED_SET attribute to prevent loops within a consortium.

Q223. The following statement about IPSG technology is correct (single choice).

The ip source checkuser-bind check-item command is used to configure VLAN- or interface-based IP packet checks, which take effect for both dynamic and static table entries.

If an interface is configured as the OKCP Scooing Tust interface, the interface can normally receive DHCP ACK and DHCPNAK responded to by the OHHNP server and DHCPOffer packets, other untrusted ports cannot receive these packets properly.

On Huawei routers, ipSG functions can be configured in Vlanif.

The IPSG can perform binding table match checks on IP packets entering and leaving the interface.

Q224. View the IGMP configuration of the interface on the router RTA as follows, and the information about the operation of the RTA is incorrect

The packet interval for a particular group query is 60 seconds

The interface IP address is 1921681.1

The maximum response time for query messages is 10 seconds

The IGMP protocol version is 2

Q225. In addition to stateless address autoconfiguration, IPV6 devices can also obtain addresses, gateways, DNS, and other information through DHCPv6

True

False

Q226. ipv6 link-local addresses can be generated through stateless autoconfiguration

TRUE

FALSE

Q227. Four routers R1, R2, R3, and R4 run IS, and the I5S router type is noted in the diagram. All four routers have an area address of 49001, and looking at the routing table on R1l shows the following results, the reason why R did not reach the route of 1034344

The routing policy configured on the ARO filters the System-ID of the default route

R2 from conflicting with R3

R and R4 Zone Planning Errors The System-ID of

R2 conflicts with R1

Q228. After BGP introduces routes for other protocols, the next hop in the BGP routing table is consistent with the next hop of the introduced routing protocol

True

False

Q229. MQC, like PBR-can only be called under the device’s Layer 3 interface.

TRUE

FALSE

Q230. 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

Q231. Users hope to be able to make the router forward and select messages according to their own defined policies on the basis of traditional route forwarding, and can adopt policy routing, and the following description of policy routing is incorrect

Policy Routing can set the next hop IP address

Policy Routing cannot be set in the next statement DSCP

Policy Routing cannot be used to set IP precedence

Policy-based routing can be used to match message lengths

Q232. The switch uses IPSG technology to verify the source address of the IP packet, and the verification matrix used by the IPSG is obtained through the ARP resolution process in the listening network

True

False

Q233. Regarding the description of the security level of the configured firewall security zone, the error is ?

Two security zones are not allowed to configure the same security level in the same system

Once the security level is set, it is not allowed to change

You can only set the security level for a custom security zone

For newly created security zones, the system defaults to a security level of 1

Q234. Is the following information about BGP4+ described correctly?

BGP4 can use dampening commands to suppress oscillations on IBGP routes.

Modifying the RouterID of BGP causes the BGP connection between routers to be re-established.

The Next Hop attribute in BGP4+ is represented by an IPv6 address, which can be the link-local address of the next hop.

BGP4+ does not support route auto-aggregate

Q235. Unlike STP, RSTP has only one BPDU type, its value is 2, and there is no TCN BPDU.

TRUE

FALSE

Q236. 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

Q237. As shown in the figure, which of the following options satisfies two routers to establish an ISIS neighbor?( Single choice questions).

Both routers are of The Level-1 type.

Both routers remain of the default type.

One of the two routers can be of the Level-1-2 type and the other of the Leve1-1 type.

The ISIS process numbers of the two routers must be consistent.

Q238. One of the things you’re doing is compressing the length of ip6 addresses as much as possible .
The existing IP6 address is 2013xX0C130F006009cO87641308, to be able to make this P6 address more concise, you can compress the IP6 address into which of the following?( Single choice questions).

2013:0:130F:0:0:09CO:876

2013:130F::9CO:876

2013:0:130F:0:0:9CO:876

213::13F::9C:876

2013:0:130F::9CO:876

Q239. Router HW1 exists in the carrier HW’s network as an MPLSLSR router. The router receives a packet carrying a label, but the label entry does not exist in its LFIB. So how does the router handle that message?

Router HW1 strips off the label and looks for the FIB using the P destination address

Router HW1 uses LDP to create an LSP and creates a new path in LFIB for the label carried in the message

Router HW1 drops the message

Router HW1 will forward the message with the default label

Q240. A campus deploys OSPF to achieve network interoperability, and an engineer configures R2 as shown in the figure, then the following description of the LSA in the OSPF network is wrong

There is no Type3 LsA flooding within Areal

There is no Type3 LSA flooding in Area2

There is Type5 LSA flooding within Areal

Area2 contains Type5 LSA generic adverb
