Juniper Juniper Certifications JN0-347 Questions & Answers

• Question 121:

  Which mechanism is used to share routes between routing tables?

  A. filter-based forwarding

  B. forwarding instances

  C. RIB groups

  D. routing instances

  Correct Answer: C

  A RIB group is a way to have a routing protocol, in most cases, place information in multiple route tables.

• Question 122:

  What are two types of IS-IS PDUs? (Choose two.)

  A. open PDU

  B. VRF PDU

  C. hello PDU

  D. link-state PDU

  Correct Answer: CD

  IS-IS hello (IIH) PDUs broadcast to discover the identity of neighboring IS-IS systems and to determine whether the neighbors are Level 1 or Level 2 intermediate systems. Link-state PDUs contain information about the state of adjacencies to neighboring IS-IS systems.

• Question 123:

  Click the Exhibit button.

  

  Referring to the exhibit, which two statement are true? (Choose two.)

  A. The device will not form adjacencies with devices in a different area;

  B. The Level 2 database will be empty.

  C. The IS-IS protocol is disabled on the device.

  D. The device will not have a Level 2 database.

  Correct Answer: AB

• Question 124:

  Click the Exhibit button. Referring to the exhibit, which two statements are true?

  

  A. The policy A routing policy takes precedence over all other policies.

  B. No policy is used for neighbor 10.0.0.4.

  C. The policy B routing policy is used by neighbor 10.0.0.4.

  D. The policy D routing policy is the only policy used by neighbor 10.0.0.2.

  Correct Answer: CD

  C: A group-level import or export statement, such as export policy B within the group ibgp-peer's statements, overrides a global BGP import or export statement. It is applied to neighbor 10.0.0.4

• Question 125:

  Click the Exhibit button.

  

  You are troubleshooting an IS-IS adjacency problem as shown in the exhibit. Which action would solve the problem?

  A. Configure matching authentication keys.

  B. Configure the INET6 family for the loopback interface.

  C. Configure the ISO family for the loopback interface.

  D. Configure matching area IDs.

  Correct Answer: D

• Question 126:

  Click the Exhibit button.

  

  The IS-IS adjacency between routers R1 and R2 will not establish. Referring to exhibit, what is the problem?

  A. The ISO address is not configured on interface ge-0/0/1.

  B. The level is not configured under protocols isis.

  C. The IP address is not configured on interface lo0.

  D. The link MTU is too small on interface ge-0/0/1.

  Correct Answer: A

• Question 127:

  You are a service provider and have multiple customers in a building. You are installing a new switch that can host all of your customers. However, you would like to ensure that one customer cannot see or broadcast to another customer. You would also like to have them use a common gateway IP address from the building. What should be used to provide this access?

  A. VLAN

  B. private VLAN

  C. filter-based VLAN

  D. Layer 2 tunneling

  Correct Answer: B

• Question 128:

  Which three statements are true regarding not-so-stubby areas (NSSAs)? (Choose three.)

  A. You cannot configure an area as both an NSSA and a stub area;

  B. An NSSA exports an external route to the backbone area as a Type 5 LSA.

  C. An NSSA exports an external route as a Type 3 LSA.

  D. An NSSA does not require an ABR.

  E. An NSSA imports an external route as a Type 7 LSA.

  Correct Answer: ABE

• Question 129:

  Which three mechanisms are associated with the bridging process? (Choose three.)

  A. pruning

  B. listening

  C. learning

  D. filtering

  E. flooding

  Correct Answer: CDE

• Question 130:

  An EBGP session sources its TCP connection from which IP address?

  A. The IP address of the primary address assigned to the loopback interface.

  B. The IP address assigned as the router ID.

  C. The IP address of the preferred address assigned to the loopback interface.

  D. The IP address of the interface that connects the two BGP speakers.

  Correct Answer: D

  The BGP session between two BGP peers is said to be an external BGP (eBGP) session if the BGP peers are in different autonomous systems (AS). A BGP session between two BGP peers is said to be an internal BGP (iBGP) session if the BGP peers are in the same autonomous systems. By default, the peer relationship is established using the IP address of the interface closest to the peer router.
