b. VSC queries VSD on network service and policies. c. VSD provides VSC with network service and policies. d. VRS agent informs VSC of the new VM placement. e. VSC deploys policy to applicable VRS agents. f. VM instantiated on the hypervisor.
- A. a->b->c->d->e->f
- B. f->d->b->a>c->-e
- C. a->f->d->b->c->-e
- D. a->b->c->f->d->-e
正解: B
質問 31
What statement is TRUE regarding service chaining provided by Nuage VCS?
- A. It consists of packets being forwarded by the local VPLS, then through the enterprise VPRN and lastly the backhaul VPLS.
- B. Service chaining only works for virtual appliances.
- C. Service chaining is flow-based traffic redirection.
- D. A virtual firewall is required to perform service chaining.
正解: B
質問 32
If we compare a Nuage Virtual Service Node to a physical service router, which module is VSC mapped to?
- A. Line card
- B. Switch fabric
- C. CPU module
- D. Internal clock
正解: B
解説:
The switching fabric is independent of the bus technology and infrastructure used to move data between nodes and also separate from the router. The term is sometimes used to mean collectively all switching hardware and software in a network.
質問 33
What statement about statistics rules on Nuage VCS is FALSE?
- A. Statistics are collected in an Elasticsearch statistics engine and are aggregated over hours, days, and months.
- B. When a TCA threshlod is exceeded, an event is displayed in the UI and a message is sent on the JMS bus.
- C. Users can define statistics rules for domain/zones/subnets/vPorts. The rule applied to the most granular object is the one used.
- D. Statistics are pushed from VRS up to VSC, which in turn sends them to the VSD stats engine.
正解: C
質問 34
Which of the following is a host-centric overlay solution for a modern data center?
- A. VPLS
- B. SPBM
- C. TRILL
- D. VxLAN
正解: D
解説:
Explanation
Modern data center, traditional technologies are limiting the speed, flexibility, scalability, and manageability of application deployments. There is emerging interest in the industry in overlay technologies (such as MPLS, VXLAN, LISP...)
質問 35
Which of the following is NOT an improvement provided by the backhaul VPLS?
- A. Reducing the number of VXLAN tunnels.
- B. Reducing the size of MAC address table.
- C. Reducing the consumption of bandwidth.
- D. Reducing the number of EVPN on the HV.
正解: A
質問 36
What statement is TRUE regarding multiple virtual IP addresses assigned to a single vPort?
- A. Every virtual IP address must be associated with a virtual MAC, which differs from the VM interface MAC address.
- B. One of the virtual IP addresses can be the same as the VM interface IP address.
- C. All virtual IP addresses of a vPort must be in the same subnet.
- D. The virtual IP addresses can be in a different subnet than the VM interface IP address.
正解: D
解説:
If you have only one public IP address available, and you want to host multiple servers, use aVIP.
質問 37
What does VSD stand for?
- A. Virtualized Services Description
- B. Virtualized Services Domain
- C. Virtualized Services Directory
- D. Virtualized Services Definition
正解: C
解説:
Nuage Virtual Service Directory (VSD)
質問 38
What benefits does virtualization bring to a data center?
- A. Multitasking with prioritized process scheduling.
- B. More processing power, memory and disk space.
- C. Mobility, flexibility, and better resource utilization.
- D. Higher bandwidth, control plane simplification and reduced forwarding tables.
正解: B

質問 39
What statement best describes the concept of Policy-Based Automation provided by Nuage Networks?
- A. The Nuage Networks VCS solution can integrate with any CMS, operate on any hypervisor, and be
deployed in any data center network. - B. The virtual machines are automatically instantiated according to the specific policy defined in the CMS.
- C. The overlay network instances are automatically created according to the configuration details defined
in a specific policy. - D. Network devices as TOR/EOR switch, and leaf/spine routers, are automatically provisioned based on the
configuration policy.
正解: A
質問 40
Which protocol is used for VSC federation?
- A. Openflow
- B. XMPP
- C. BGP VPN-IPv4
- D. BGP EVPN
正解: A
解説:
The VSC uses standard protocols to peer with existing networks, allowing it to discover full network topology and reachability. Through Openflow, it distributes relevant switching and routing information to hypervisors within the virtualized datacenter network.
質問 41
What statement regarding Openflow sessions in data center networks is TRUE?
- A. By default, the Openflow session is established with TCP port 6633.
- B. Openflow sessions can be established over either the data plane or the management plane.
- C. Openflow sessions run between VSCs.
- D. Security in mandatory with SSL encryption.
正解: D
解説:
SSL (Secure Sockets Layer) is the standard security.
質問 42
What statement about floating public IP addresses in the Nuage environment is CORRECT?
- A. There can be more that one floating IP address associated with one vPort.
- B. Once a floating IP is configured on the vPort , the VM will stop using its enterprise private IP address.
- C. NAT is performed for the traffic leaving the enterprise domain and entering the public network.
- D. They are managed by enterprise admin users.
正解: A
質問 43
What statement regarding active/standby VSD cluster is TRUE?
- A. XMPP connections to the secondary cluster are blocked.
- B. VSP components (eg: VSCs) need reconfiguration after failover.
- C. Both the primary and secondary cluster are running all VSD services.
- D. The active/standby mode is also supported in standalone VSD.
