NEW QUESTION # 17
An update to your organization's network security requirements document requires management traffic to be isolated in a non-default routing-instance. You want to implement this requirement on your Junos-based devices.
Which two commands enable this behavior? (Choose two.)
Answer: A,D
Explanation:
Explanation
To isolate management traffic in a non-default routing-instance on Junos-based devices, you can use the set system management-instance and set routing-instances mgmt_junos commands12.
set system management-instance: This command associates the management interface (usually named fxp0 or em0 for Junos OS, or re0:mgmt-* or re1:mgmt-* for Junos OS Evolved) with the non-default virtual routing and forwarding (VRF) instance1. After you configure the non-default management VRF instance, management traffic no longer has to share a routing table with other control traffic or protocol traffic1.
set routing-instances mgmt_junos: This command creates a new routing instance named mgmt_junos. The name of the dedicated management VRF instance is reserved and hardcoded as mgmt_junos; you cannot configure any other routing instance by the name mgmt_junos1.
Therefore, options C and D are correct. Options A and B are not correct because they attempt to assign an interface to the mgmt_junos routing instance, which is not necessary for isolating management traffic1.
NEW QUESTION # 18
Which statement about the default action of MAC limiting is true when the number of MAC addresses has hit the limit set?
Answer: C
Explanation:
According to the Juniper documentation 1 , MAC limiting is a feature that enhances port security by limiting the number of MAC addresses that can be learned within a VLAN. When the MAC limit is exceeded, the switch can perform different actions, such as ignoring, dropping, logging, shutting down, or disabling the offending port. The default action is to drop the packets with new MAC addresses and log a message 2 .
Therefore, the correct answer is B.
The other options are not correct because:
* A. The switch will not shut down the offending port for five minutes by default. This is a configurable action, but not the default one 2 .
* C. The switch will not flood traffic out of all ports for the offending MAC address by default. This is a possible consequence of ignoring the packets with new MAC addresses, but not the default action 2 .
* D. The switch will not shut down MAC learning on the offending port for five minutes by default. This is another configurable action, but not the default one 2 .

NEW QUESTION # 19
Which two multicast IP addresses are used for link-state update packets? (Choose two.)
Answer: B,C
Explanation:
Link-state update packets are used to flood link-state advertisements (LSAs) among OSPF routers. The destination IP address of these packets depends on the network type and the state of the interface. On broadcast and point-to-point networks, OSPF uses two IP multicast addresses: 224.0.0.5 for all OSPF routers and 224.0.0.6 for all designated routers (DRs) and backup designated routers (BDRs)12. If the interface state is DR or BDR, the link-state update packets are sent to 224.0.0.5. Otherwise, they are sent to 224.0.0.63. On non-broadcast networks, such as Frame Relay or ATM, link-state update packets are sent as unicasts to each adjacent neighbor3. Therefore, the correct answer is A and D.

NEW QUESTION # 20
Which statement correctly describes the function of a Junos OS "generated route"?
Answer: D
Explanation:
A generated route in Junos OS is a type of aggregate-like route that becomes active in the routing table only when at least one contributing (more specific) route is present. Generated routes are commonly used for route summarization, allowing an administrator to advertise a summarized prefix only when the underlying specific routes actually exist.
NEW QUESTION # 21
Referring to the exhibit, which three statements are correct? (Choose three.)
Answer: A,B,E
Explanation:
The IP source guard is enabled.
The configuration shows that ip-source-guardis explicitly enabled under dhcp-security.
Dynamic ARP inspection is enabled.
The configuration also includes arp-inspectionunder dhcp-security, which indicates that Dynamic ARP Inspection (DAI) is enabled.
DHCP snooping is enabled.
DHCP snooping is implied as enabled because both IP source guard and ARP inspection are dependent on the DHCP snooping database to function properly. Even though DHCP snooping is not explicitly mentioned, its presence is required for these features to work.
