Your customer has a high priority application housed within a corporate headquarters data center and two regional data centers. The customer cannot afford to provide individual data circuits to each location. The customer requires an end-to-end CoS architecture that will minimize oversubscription in the access switch.
Which three CoS components will meet the customer's requirements? (Choose three.)
A. explicit congestion notification
B. priority flow control
C. code-point aliases
D. CoS rewrite rules
E. standard flow control
正解:A,B,D
質問 2:
What are two characteristics of in-band network management? (Choose two.)
A. In-band network management is less complicated because a dedicated management channel is not used.
B. A dedicated management channel is used so disruption in the core network does not affect the ability to manage devices.
C. A network protocol, such as SSH or VNC, is used to connect for device management.
D. A hardware solution, such as terminal server, is used to connect for device management.
正解:A,C
質問 3:
You must make certain that your server traffic is load balanced across redundant connections to your access layer in a traditional three-tier architecture. You must also ensure that an access switch failure does not affect reachability to your servers.
In this scenario, which action would you perform to complete this task?
A. Use LAG and establish a connection to a single access switch that is a member of a Virtual Chassis.
B. Use MC-LAG and establish a connection to two different access switches.
C. Use MC-LAG and establish a connection to two different access switches in the same Virtual Chassis.
D. Use LAG and establish two connections to two different access switches.
正解:B
質問 4:

D. NFV
正解:D
質問 5:
The QFX5100 can be configured to be a virtual tunnel endpoint (VTEP) in your Clos IP fabric.
What is the importance of this capability?
A. It allows attached bare metal servers to communicate using an overlay VXLAN network.
B. It prevents the QFX5100 from learning the MAC addresses of an overlay network.
C. It allows the QFX5100 to perform the PE role of a Layer 2 pseudowire.
D. It allows the QFX5100 to perform the PE role of an EVPN.
正解:A
質問 6:
In a Clos IP fabric, which advantage does EBGP signaling have between spine and leaf nodes over using IBGP?
A. By default, EBGP supports multihop sessions between peers.
B. When using EBGP between all members, a single advertised route will belearned by all members.
C. EBGP does not require the configuration of next-hop self.
D. A leaf node can have multiple EBGP sessions with a spine node.
正解:B
