Juniper Data Center, Associate (JNCIA-DC) Sample Questions (Q65-Q70):

NEW QUESTION # 65
Exhibit:

R2 received an OSPF update from R1, and it received the same update from R3.
Referring to the exhibit, what will R2 do?

A. R2 does nothing with R3's update.
B. R2 ignores the update from R3.
C. R2 acknowledges R3 and discards it.
D. R2 ignores the update from R1.

Answer: B

Explanation:
In the exhibit, R2 receives the same OSPF update from both R1 and R3. OSPF has mechanisms toprevent unnecessary processing of duplicate LSAs (Link-State Advertisements).
Step-by-Step Breakdown:
* OSPF LSA Processing:
* OSPF uses LSAs to exchange link-state information between routers. When a router receives an LSA, it checks if it already has a copy of the LSA in its Link-State Database (LSDB).
* Duplicate LSAs:If R2 has already received and processed the update from R1, it willignore the update from R3because it already has the same LSA in its database. OSPF uses the concept of flooding, but it does not reprocess LSAs that it already knows about.
* R2 Behavior:R2 will keep the update from R1 (the first one it received) and will ignore the same LSA from R3, as it is already in the LSDB.
Juniper Reference:
* OSPF LSA Processing: Junos adheres to OSPF standards, ensuring that duplicate LSAs are not processed multiple times to avoid unnecessary recalculations.

NEW QUESTION # 66
Martian addresses are:

A. Unroutable addresses that are generally filtered by routers.
B. Addresses used for load balancing.
C. Addresses used in MPLS.
D. Special routes for interplanetary communication.

Answer: A

NEW QUESTION # 67
Which two statements are correct about aggregated Ethernet bundles? (Choose two.)

A. You must purchase a services license for the chassis to support aggregate Ethernet interfaces.
B. You must specify which interfaces are members of a specific aggregated Ethernet bundle.
C. You must enable the chassis to support aggregated Ethernet interfaces.
D. You must enable LACP when configuring aggregated Ethernet bundles.

Answer: B,C

NEW QUESTION # 68
Which two statements are correct about VLAN tags? (Choose two.)

A. VLAN tags are required on access ports.
B. VLAN tags carry a VLAN ID and priority.
C. VLAN tags can be inserted or removed by trunk interfaces.
D. VLAN tags require multiple forwarding tables.

Answer: B,C

Explanation:
VLAN tagsare used in Ethernet frames to identify and differentiate traffic between multiple VLANs. They are especially important for devices like switches that handle multiple VLANs on the same physical link.
Step-by-Step Breakdown:
* VLAN Tag Contents:
* VLAN ID: The tag contains a 12-bit VLAN ID field that identifies the VLAN to which the frame belongs.
* Priority: The tag also includes a 3-bit priority field (also known as 802.1p priority) used for QoS (Quality of Service) to prioritize traffic.
* Trunk Ports and VLAN Tagging:
* Trunk Portsare used to carry traffic for multiple VLANs across a single link. These interfaces insert (tag) VLAN identifiers into frames when they leave the switch and remove (untag) them when frames enter the switch.
* Access Ports:VLAN tags are typically not used onaccess ports(ports that connect to end devices) since those ports are configured to be part of a single VLAN, and the traffic doesn't need VLAN tags.
Juniper Reference:
* VLAN Tagging: Juniper switches support VLAN tagging and ensure that frames are tagged or untagged as they traverse trunk or access ports, respectively.

NEW QUESTION # 69
Which two statements describe an IP fabric? (Choose two.)

A. An IP fabric allows devices to always be one hop away.
B. An IP fabric provides traffic load sharing.
C. An IP fabric uses spine and leaf devices.
D. An IP fabric depends on Layer 2 switching.

Answer: B,C

Explanation:
AnIP fabricis a network topology designed to provide a scalable, low-latency architecture that is typically implemented in modern data centers. It usesspine and leafswitches and enables efficienttraffic load sharing across the network.
Step-by-Step Breakdown:
* Spine-Leaf Architecture:
* Leaf Devices: These switches connect to servers and edge devices within the data center. Each leaf switch connects to every spine switch.
* Spine Devices: These high-performance switches interconnect all the leaf switches. There are no direct connections between leaf switches or spine switches. This architecture ensures that any two endpoints within the fabric are only one hop away from each other, minimizing latency.
* Traffic Load Sharing:
* An IP fabric leveragesEqual-Cost Multipath (ECMP)to distribute traffic evenly across all available paths between leaf and spine switches, providing effective load balancing. This ensures that no single link becomes a bottleneck and that traffic is distributed efficiently across the network.
Juniper Reference:
* Juniper providesQFX Seriesswitches optimized for IP fabric topologies, allowing for scalable deployments in modern data centers.
* EVPN-VXLAN: Often used in IP fabrics to extend Layer 2 services across the fabric with Layer 3 underlay, enabling both efficient routing and bridging.
