Juniper JN0-1361 問題集

質問 1：
Exhibit:

You are asked to design a solution that will provision a circuit from the corporate headquarters to a remote branch. The circuit must be secure, and must support IGP adjacencies. IPsec has been chosen to secure traffic across the WAN connection.
Referring to the exhibit which statement describes another requirement for this circuit to function correctly?
A. You must increase the MTU of the IPsec tunnel to more than 1500 bytes to allow routing updates across the circuit.
B. You must implement GRE over IPsec to establish routing protocols across the circuit.
C. You must use a service provider Layer 2 VPN to establish routing protocols across the circuit.
D. You must use a service provider Layer 3 VPN to establish routing protocols across the circuit
正解：B

質問 2：
Your customer wants to use NorthStar to communicate with network devices and acquire the MPLS topology. Which protocol is recommended for this purpose?
A. ISIS
B. OSPF
C. PIM-SSM
D. BGP-LS
正解：D

質問 3：
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 4：
You are asked to design a BNG solution using MX Series routers You want to dynamically assign per-subscriber configuration parameters using VSAs.
Which external service is required to accomplish this task?
A. DHCP
B. RADIUS
C. TACACS
D. 802.1X
正解：B

質問 5：
Your customer requires redundant routers and wants to use VRRP for the default gateway at their Internet edge. Which two statements are correct in this scenario? (Choose two )
A. VRRP dynamically elects master and backup routers
B. The VRRP master and backup send advertisements to each other at regular intervals.
C. VRRP for IPv6 provides a much faster switchover to an alternate default router than IPv6 neighbor discovery procedures
D. VRRP will only support two routers
正解：A,B

質問 6：
Your customer connects to their service providers using fiber-based Ethernet connections in a shared collocation room. The customer has expressed concerns about wire tapping and man-in-the-middle attacks, and has asked for your design recommendation to minimize such attacks.
Which service addresses the customer's concern?
A. 802 3ad
B. BGPFIowSpec
C. MACsec
D. 802 1x
正解：C
