Juniper Juniper Other Certification JN0-1361 Questions & Answers

• Question 51:

  Your customer wants an MPLS-based L3VPN service between multiple remote locations. Which two statements are true regarding the customer's WAN edge devices? (Choose two )

  A. They must have EBGP configured.

  B. They require routes for all remote sites.

  C. They must have MPLS configured.

  D. They require IP connectivity with the PEs.

  Correct Answer: BD

• Question 52:

  Your customer wants to use NorthStar to communicate with network devices and acquire the MPLS topology. Which protocol is recommended for this purpose?

  A. PIM-SSM

  B. OSPF

  C. BGP-LS

  D. ISIS

  Correct Answer: C

• Question 53:

• Question 54:

  Your customer's WAN edge connects to two service providers SP-A and SP-B. The customer is advertising a single /22 subnet to both service providers through EBGP peering sessions. The customer wants to influence inbound traffic to the advertised /22 destination prefix so that it passes through SP-A when both paths are operational. Which action meets the customer's requirement?

  A. Advertise the prefix to SP-A with a lower MED value than that sent to SP-B.

  B. Advertise the prefix to SP-B with an origin of unknown.

  C. Advertise the prefix to SP-B with a lower MED value than that sent to SP-A.

  D. Advertise the prefix to SP-A with an origin of unknown.

• Question 55:

  Which security implementation does Juniper Networks recommend for all core routers in a service provider network?

  A. intrusion and detection prevention

  B. unified threat management

  C. application firewall

  D. stateless loopback firewall filter

  Correct Answer: D

• Question 56:

  What are three components of a class-of-service scheduler? (Choose three.)

  A. transmit rate

  B. forwarding class

  C. queue priority

  D. delay buffer size

  E. policing rate

  Correct Answer: ACD

  Junos OS schedulers allow you to define the priority, bandwidth, delay buffer size, rate control status, and RED drop profiles to be applied to a particular queue for packet transmission

• Question 57:

  You are designing a multi-site data center environment with data center interconnects between sites. Which two statements are true in this scenario? (Choose two. )

  A. VPLS can be used to interconnect the multiple sites.

  B. EVPN with VXLAN can be used to interconnect the multiple sites.

  C. The data centers must be connected with a full mesh design.

  D. All data centers must be in the same Layer 2 broadcast domain and subnet.

  Correct Answer: AB

• Question 58:

  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. Force the ISP A to ISP D traffic over RSVP-signaled LSPs.

  B. Adjust the BGFs LOCAL PREF attribute to ensure that the raw IP packets follow the required path.

  C. Adjust the OSPF metrics of each link so that the raw IP packets follow the required path.

  D. Force the ISP A to ISP D traffic over LDP-signaled LSPs.

  Correct Answer: A

• Question 59:

  Exhibit: Which routing protocol design will accomplish these goals?

  

  A. Enable a full mesh of IBGP sessions between the routers in ISP B.

  B. Redistribute the BGP routes learned from ISP A into the OSPF instance running in ISP B.

  C. Configure static routes to ISP A on each router within ISP B.

  D. Configure each router in ISP B to peer with a par of route reflectors.

  Correct Answer: D

• Question 60:

  Your applications are migrating from a legacy data center to an EVPN over a VXLAN-based VM environment. A few critical legacy applications not support this environment and must remain on bare metal servers and the applications must be able to access the Internet. What must be included in the VXLAN design to satisfy these requirements?

  A. VTEP tunneling

  B. VXLAN gateway

  C. SR-IOV

  D. nested VM capability

  Correct Answer: B
