Question 46

The VRRP is enabled on the firewall dual-system Intranet users use NAT to access extranet FTP services
Which of the followingstatements are true?

A.VRIDs of the VRRP do not need to be bound with the NAI during NAI configuration in the outbound
directionbetween domains.

B.The FTP Nat Alg function must be enabled on the firewall

C.The NAT cannot be used in easy IP mode.

D.VRIDs of the VRRP must be bound with the NAT during NAT configuration in the outbound direction
between domain.

Question 47

Which of the following statements about the working principle f LDAP FRR are true?

A.Multiple LSPs can be up on the ingress node, that is entries about multiple backup LSPs are generated in
the forwarding table according to the priority of the FRR, implementing multi-layer protection.

B.After LDP FRR is enabled, a backup LSP is generated both the primary and backup LSPs are stored in
the forwarding table.

C.After LDP FRR enable, a backup can degenerated for a primary LSP to prevent serious packet loss
during fats flapping of the primary LSP.

D.LDP TFRR can be deployed on the ingress node and the intermediate node. The primary and backup
LSPas are recorded in the ILM table on the intermediate node and on the FIB table on the ingress node.

Question 48

Exhibit:

RTA is an edge route of the MPLS backbone network. It provides the access for users under layer 2 switches and differentiates user by subinterface. User access VALN 100 and has subscribed to the His ViIP , and services. According to 802 1p priorities, the value 0 indicates the HIS service, 1 indicates the VoIp service and 4 indicate the IPTV service. The DiffSerc model is deployed in E-LSP mode on the MPLS network, And the STC is configured for subinterface on the access side of RTA (the qos phb disable command is not configured). Outgoing on the traffic on the G1/0/0.1 suninterface involves the His VoIP, and services on the access side of RTA.
Which statements about EXP about values corresponding to these three services is true?

A.The EXP values must be 0, 1, and 4.

B.Only two EXP values be contains, and the values are certain.

C.At least three EXP values be contained, and the values are uncertain.

D.Only one EXP may be contained, and the value is uncertain

Question 49

Exhibit:

The figure shows the typically mode in which a common softswitch access the bearer network. VRRP is enabled on RTA and RTB. In normal cases, RTA is the VRRP master router and RTB is the VRRP is the VRRP salve router. The ETH_trunk is enabled between RTA RTB. IF VRRP is not bounded to BFD and each [parameter uses their default settings, which statement is the true when the upstream link of RTA is faulty?

A.The ARRP status remain unchanged but the downstream traffic is forwarded from RTB to the MSoft through RTA

B.RTB cannot receive the heartbeat packet from RTA, and both routers become master routers.

C.The VRRP status remain unchanged but the downstream traffic is directly forwarded from RTB to the MSoftx.

D.The ARRP status immediately between RTA and RTB and RTB, and RTB becomes the master router.

Question 50

Which statement about the OSPF VPN is true? (B)

A.An OSPF process can be configured with one or multiple primary domain IDs.

B.OSPF ASs are differentiated by domain ID. Therefore, devices within one AS must be configured with the same domain ID.

C.When a PE is an OSPF ABR, the PE is connected to a CE only in a non-backbone OSPF area.

D.A VPN instance can include multiple OSPF processes. An OSPF process can be bound to multiple VPN instances.
