Juniper Enterprise Routing and Switching, Professional (JNCIP-ENT) Sample Questions (Q89-Q94):

NEW QUESTION # 89
A customer requires that the switch responds to an ARP request only if the source and target IP address are on different subnets.

Referring to the Exhibit, how would you accomplish this task?

A. Change the proxy ARP parameter setting to restricted.
B. Enable the no-gratuitous-arp request command under the interface hierarchy.
C. Create a static ARP entry for the host.
D. Remove the proxy ARP setting and clear the entry.

Answer: A

NEW QUESTION # 90
You must provide network connectivity to hosts that fail authentication.
In this scenario, what would be used in a network secured with 802.1X to satisfy this requirement?

A. Use the server-reject-vlan command to specify a guest VLAN.
B. Configure the port as a spanning tree edge port.
C. Configure the native-vlan-id parameter on the port.
D. Configure a secondary IP address on the port for unauthenticated hosts.

Answer: A

Explanation:
* Understanding 802.1X Authentication:
* 802.1X is a network access control protocol that restricts access until the device or user is authenticated.
* Guest VLAN Configuration:
* When hosts fail authentication, they need to be placed in a separate VLAN to provide limited network access.
* server-reject-vlan Command:
* This command configures a VLAN for unauthenticated devices.
* Ensures that devices that fail authentication are placed in a designated guest VLAN.
* Configuration Example:
shell
Copy code
set protocols dot1x authenticator interface ge-0/0/1.0 server-reject-vlan guest-vlan References:
* Juniper 802.1X Authentication Configuration Guide
* Juniper Guest VLAN Configuration

NEW QUESTION # 91
A BGP network has been designed to provide resiliency and redundancy to a multihomed customer network.
Which two statements are correct in this scenario? (Choose two.)

A. A routing policy will be required to forward traffic to both next hops.
B. The ttl statement must be configured to accommodate peering to a loopback address of a directly connected peer.
C. Both the next hops will be used to forward traffic to R2.
D. The TTL value of 1 is set to limit the scope of the EBGP session.

Answer: A,D

Explanation:
B - because only one next hop in forwarding table C- becuse TTL=1 limiting bgp connection to be established only over loopbacks interface
https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/topic-map/multihop-sessions.html Use the multihop statement to alter the default use of the neighbor's physical address. In addition, you can also specify a time-to-live (TTL) value in the BGP packets to control how far they propagate. We use a TTL value of 1 to ensure that the session cannot be established across any other backdoor links in the network.

NEW QUESTION # 92
You are deploying new Juniper EX Series switches in a network that currently is using Cisco's Per- VLAN spanning tree plus (PVST+) and you must provide compatibility with this environment.
Which spanning tree protocol do you deploy in this scenario?

A. STP
B. RSTP
C. MSTP
D. VSTP

Answer: D

Explanation:
VSTP has the following benefits:
Connects devices that are not part of the network
Compatible with Cisco PVST+
VSTP and RSTP are the only spanning-tree protocols that can be configured concurrently on a device.
VSTP Restrictions
VSTP has these restrictions:
The EX Series switches EX4300, EX4600 and the QFX platforms QFX5100,QFX3500,QFX3600 support 510 Vlans on VSTP.
VSTP is not supported on the SRX platform - just STP/RSTP/MSTP are supported on SRX Series.
On EX Series (except EX9200) and QFX Series switches running Junos OS that supports ELS- VSTP can support up to 510 VLANs.
On EX9200 switches-VSTP can support up to 4000 VLANs.
On an EX Series switch running Junos OS that does not support ELS-VSTP can support up to
253 VLANs.

NEW QUESTION # 93
The connection between DC1 and DC2 is routed as shown in the exhibit.
In this scenario, which statement is correct?

A. An IP prefix route provides encoding for intra-subnet forwarding.
B. L3VPN must be enabled to advertise reachability.
C. Type 2 and Type 5 routes will be exchanged between DC1 and DC2.
D. The border devices must be able to perform Layer 3 routing and provide IRB functionality.

Answer: D

Explanation:
In the given scenario, the connection between DC1 and DC2 is routed through a Layer 3 network. This indicates that the devices connecting the two data centers must be capable of performing Layer 3 routing to ensure that traffic can be properly forwarded across the network. Additionally, the use of VXLAN suggests that Integrated Routing and Bridging (IRB) functionality is required to enable communication between Layer
2 networks over the Layer 3 infrastructure.
* The border devices (QFX10002) must handle Layer 3 routing to manage IP traffic between the data centers.
* IRB functionality is necessary for routing between VLANs, allowing VXLAN to carry Layer 2 traffic across the Layer 3 network.
References:
* The diagrams indicate the use of VXLAN for Layer 2 extension over a Layer 3 network.
* The need for IRB is suggested by the presence of routed interfaces (IRB1 and IRB2) in the data center diagrams.
* The "Tech Ops Managed Router Juniper Install Guide" provides insights into the Layer 3 routing capabilities and configurations necessary for such setups.
