What RR deployment methods does Huawei SD-WAN solution support? (Multiple choice)
- A . RR multi-region deployment
- B . RR is deployed together with the site
- C . RR independent deployment
In the SD-WAN solution, which statement is wrong about the remote controller disaster recovery solution?
- A . The northbound and southbound controller uses a unified domain name or IP. Tenants and devices access the main cluster of the controller through a unified domain name or IP. After the active/standby switchover, traffic is automatically switched to the new active cluster.
- B . The main and backup clusters of the controller run at the same time. Only the main cluster can provide normal services to the outside world, and the backup cluster does not provide services to the outside world. The data in the operation of the main cluster will be synchronized to the backup cluster in real time to ensure data consistency.
- C . Huawei SD-WAN controller active and backup solution supports multiple active clusters and multiple standby clusters
- D . Remote disaster recovery supports disaster recovery and backup capabilities between two clusters. The number of nodes in the main cluster and the disaster recovery backup cluster must be consistent.
Which of the following re-registration algorithms is used by OceanProtect dedicated backup storage?
- A . Similar deduplication
- B . Fixed-length deduplication
- C . Multi-layer online variable length deduplication
- D . Later deletion
Which statement about EVPNv4/v6 service design is correct? (Multiple choice)
- A . The VPN instance deploys RT to control routing cross-over to achieve network-wide routing interoperability. The same VPN service on the entire network is planned to be accessed with the same VLAN ID.
- B . Color of published routes: Use the same color D between different VPNs, and set the colors for VPN published routes through routing policies. At the same time, the VPN instance is configured with a default iteration color that is consistent with the planned route release color. The color of the route advertisement must be consistent with the color of the corresponding tunnel group planned.
- C . Different VPNs iterate different SRv6 Policoy Group tunnels. Different SRY6 Policy Group tunnels are distinguished by different colors. Each SRr6 PolicyGroup plans different Polioy tunnels based on the different service flows carried by the VPN.
- D . The L3EVPN route iterates the corresponding SRv6Policy Group tunnel through the Color attribute carried. Different DSCPs are set in the Group group to enter the SRr6 Poicy tunnel of the corresponding color. When forwarding, the forwarding plane forwards according to the packets carried
For centralized backup systemarchitecture design, 3-2-1 rule should be recommended, what is the details of 3-2-1? For centralized backup system architecture, it is recommended to adopt the 3-2-1 principle. What is the 3-2-1 principle?
- A . 3 data copies, 2 sites, 1 backup storage medium
- B . 3 backup storage media, 2 data copies, 1 copy in an off-site location
- C . 3 data copies are stored in 2 different backup storage media, of which 1 copy is in an off-site location
- D . 3 sites, 2 data copies, 1 backup storage medium
What functions does the new version of SecoManager not have?
- A . Firewall device management
- B . Replace ATIC as the network manager of AntiDDoS
- C . Routing and switching equipment management
- D . Replace eLog as log management device
Which of the following descriptions about OceanProtect dedicated backup storage is incorrect?
- A . OceanProtect X9000 control node can accommodate 36 SAS SSDs
- B . The control node of OceanProtect X6000 can accommodate 25 SAS SSDs
- C . The control node of OceanProtect x8000 can accommodate 25 SAS SSDs
- D . OceanProtect’s dedicated backup storage HDD hard disk enclosure can accommodate 24 NL-SAS hard disks
Regarding the OceanStor Dorado mid-range storage, which of the following descriptions are correct? (Multiple Choice)
- A . Performance expansion: 16-control RDMA high-speed interconnection
- B . Only supports ALUA architecture
- C . A single alarm supports up to 16 NVMe hard disk enclosures
- D . Distributed file system: A single file system can provide reading and writing through multiple controllers
CampusInsight uses the SNMP protocol to collect data, rather than the industry’s de facto standard StreamingTelemetry technology.
- A . True
- B . False
What are the main differences between NAT Server and policy-based purpose NAT? (Multiple choice)
- A . The NAT Server has a higher priority than the policy-based destination NAT. After the first packet reaches the firewall, it is first processed by the NAT Server and the Server map table is searched. If the Server map table cannot be found, the policy-based destination NAT is then performed.
- B . When the NAT Server is not configured with no-reverse, it can perform NAT conversion in both directions. Policy-based destination NAT can only perform one-way NAT conversion.
- C . The server-map table is created after the NAT Server is configured, but the destination NAT is not created.
