Complete list of current Q & A>> Download Huawei HCIE Datacom (H12-891) – Quiz 1 / 15 In MPLSVPN, in order to distinguish between IPv4 prefixes that use the same address space, the RD value is added to the IPv4 address, and the following options are described correctly as ? A. RD can be used to control the publication of VPN routing information B. On a PE device, each VPN instance corresponds to an RD value, and the RD value must be unique on the same PE device C. RD is encapsulated in the Update message as an extended community attribute of BGP during delivery D. After the PE receives an IPv4 route from CE, it adds an RD to the route to IPv4 that translates to a globally unique VPN-IPv4 route and publishes it on the public network 2 / 15 Which of the following default routing delivery methods does OSPF support?( Multi-select) A. It can be issued without force B. Can be issued on ABR C. Issuance can only be enforced D. Answer can be issued on ASBR 3 / 15 How do.8021w and 8021D handle BPDUs? A. The 8021D bridge only forwards BPDU packets received from the root bridge B. 8021D bridges do not forward BPDU packets C. The 8021w bridge only forwards BPDU packets received from the root bridge D. 8021w Bridge does not forward BPDU packets 4 / 15 What improvements have been made to the IGMPv2 protocol compared to IGMPv1? ( Multiple Choice) A. Added maximum response time field B. Added high group messages C. Added specific group query message D. Added a specific source group query packet 5 / 15 When deploying the ISIS protocol in an IPv6 environment , the following statement is correct A. By default, the DIS priority for broadcast network interfaces at Level-1 and Level-2 is 1 B. In broadcast networks, IPv4 and The DIS priority for IPv6 can be set separately C. In the same broadcast network. If each router supports both IPv4 and IPv6 The DIS for IPv4 and IPv6 must be the same device D. IS-IS is configured under the finger port is ISIS silent, this interface will not send ISIS packets, but will receive ISIS packets 6 / 15 Which of the following options uses an alternate channel to enable communication between IPV6 addresses? A. DualStack B. 6to4 C. ISATAP D. NAT64 7 / 15 Is the following description of the BSR/RP mechanism correct? A. PIM-SM domain can have more than one C-BSR, but only one BSR can be elected by the C-BSR that receives the C-RP Packets are collected C-one RP information B. BSR advertises BSR and C-RP information to all routers in the PIM-SM domain by flooding Bootstrap packets C. A C-BSR can also collect C-RP information by receiving C-RP packets 8 / 15 The following statement about the Security Alliance SA in IPSec is wrong with ? A. SA is uniquely identified by a triple that includes the Security Parameter Inder ,Security Parameter Inder), the source IP address, and the Security Protocol Number (ASESP) used B. Use the display ipsec command to view information such as the encryption method used with another IPSEC peer, the traffic of interest, and so on. C. IPSec only supports encrypting data using the pair encryption algorithm. D. IpSec peers must be at a two-way SA to establish an IPSec VPN connection to close 9 / 15 What are the following advanced features supported by BGP EVPN? A. ARP broadcast suppression B. VRRP overVXLAN C. Multi-active gateway D. WI-AN Qos 10 / 15 The rules for RR to publish routes break the rules for horizontal segmentation of IBGP, so it is possible to cause loops within the AS. What routing attributes does RR use to prevent loops? A. Nexthop B. Originator ID C. AS-PATH D. Cluster List 11 / 15 By default, huawei firewalls provide the following security areas: A. Trust zone B. Security zone C. Local zone D. Untrust Zone 12 / 15 Which of the following does the digital certificate not contain? A. Digital envelopes B. Issued by C. Digital signature D. Public key information 13 / 15 Firewall security policies have the condition for traffic matching to be ?( Multi-select) A. apply B. Source item security zone C. Source item IP address D. Message length 14 / 15 In an HW MPLS network, what parameters are used to define a forwarding equivalent class?? A. BGP MED B. IP prefix C. RSVP requests resource reservation D. from CE Layer 2 links 15 / 15 Which of the following options enables encapsulation and unencapsulation of VXLAN messages? A. VBDIF B. VLANIF C. BD D.
