Juniper JN0-1362 問題集

質問 1：
You are designing several MPLS virtual routing and forwarding (VRF) instances on all provider edge (PE) routers. Routes within each VRF should be exchanged between all PE routers provisioned for that VRF.
For each VRF routing instance which two attributes must match on all related PE routers? (Choose two )
A. instance type
B. interfaces
C. router ID
D. VRF target
正解：A,D

質問 2：
A customer requests that you design their Layer 3 VPN solution so that all site-to-site traffic goes through a central site, in a hub-and-spoke fashion You must choose between using one or two interfaces on the hub WAN link.
In this scenario, which solution would you use?
A. Use two interfaces on the hub WAN link to reserve one interface for higher Priority traffic.
B. Use two interfaces on the hub WAN link to allow traffic to go from the spokes to the hub on one interface and from the hub to the spokes on the other interface.
C. Use one interface on the hub WAN link to ensure simplicity, since only a single route target is required across the entire Layer 3 VPN.
D. Use one interface on the hub WAN link, since both hub and spoke sites will require a second VRF for route-leaking purposes.
正解：C

質問 3：
A customer wants to consolidate all remote site connections into a single enterprise WAN for backhual to the corporate headquarters and data centers.
Which solution satisfies this requirement?
A. Data Center Interconnect
B. private WAN
C. WAN aggregation
D. Internet edge
正解：A

質問 4：
Exhibit.

You are asked to ensure that most traffic that traverses your network is load balanced over all of the equal cost links between the routers in your network. However, you must also ensure that traffic from ISP A that is destined for ISP D must traverse the R1-R2-R3-R4-R5 path.
Referring to the exhibit how would you accomplish this task?
A. Adjust the OSPF metrics of each link so that the raw IP packets follow the required path.
B. Force the ISP A to ISP D traffic over LDP-signaled LSPs.
C. Force the ISP A to ISP D traffic over RSVP-signaled LSPs.
D. Adjust the BGFs LOCAL PREF attribute to ensure that the raw IP packets follow the required path.
正解：C

質問 5：
You are asked to design a WAN for a large enterprise. Each site must have multiple connections for redundancy. MPLS is not available at every site but it is preferred where available.
Which topology satisfies these design requirements?
A. hub-and-spoke Internet WAN
B. full mesh MPLS VPN
C. full mesh SD-WAN
D. hub-and-spoke SD-WAN
正解：D

質問 6：
You are implementing an MPLS-based WAN environment to connect remote sites to the corporate headquarters (HQ) However, the service provider at the HQ location does not provide service at the location of one of the remote sites.
Which statement is true in this scenario?
A. A dedicated leased line will need to be used to connect to the remote site.
B. A circuit can be bridged across multiple service providers for end-to-end connectivity.
C. A public WAN circuit can be provisioned over the Internet that will provide the same level of service.
D. A hub site in a location where both service providers have a presence will need to be deployed.
正解：B

質問 7：
You are asked to design a DDoS prevention system to help mitigate denial-of-service attacks that target your customers. The management group wants to know the effect FlowSpec may have on current network operations if it is implemented as a solution.
In this scenario which two statements are correct? (Choose two )
A. FlowSpec can block traffic based on stateful flow information.
B. FlowSpec requires Jflow implementation and licensing.
C. FlowSpec can block traffic based on the source address.
D. FlowSpec can block traffic based on the destination address.
正解：C,D

質問 8：
What are two risks when using a source-based RTBH solution? (Choose TWO)
A. The target of an attack would be blocked resulting in a target being offline.
B. The attacker address could be a CGNAT address resulting in a larger service outage for users.
C. The attacker's address could be unknown.
D. The target of the attack may not support RTBH.
正解：B,D
