NEW QUESTION # 116
You are asked to enforce user authentication using a captive portal before users access the corporate network.
Which statement is correct in this scenario?
- A. A captive portal can be bypassed using an allowlist command containing a device's IP address.
- B. When enabled, a captive portal must be applied to each individual interface.
- C. HTTPS is the default protocol for a captive portal.
- D. All Web browser requests are redirected to the captive portal until authentication is successful.
Answer: D
Explanation:
Captive Portal Functionality:
* Captive portals are used to enforce user authentication by redirecting web browser requests to a login page until authentication is successful.
Operation:
* When a user connects to the network, their HTTP requests are intercepted and redirected to the captive portal login page. This process continues until the user provides valid credentials.
Implementation:
* Juniper Configuration:
shell
Copy code
set security authentication-web redirect-url "http://<captive-portal-url>" set security zones security-zone <zone> interfaces <interface> host-inbound-traffic system-services http set security zones security-zone <zone> interfaces <interface> host-inbound-traffic system-services https set access profile <profile-name> captive-portal
* This configuration ensures that all HTTP/HTTPS traffic is redirected to the specified captive portal for authentication.
References:
* Detailed configuration and operation are documented in "Tech Ops Managed Router Juniper Install Guide" and related documents.

NEW QUESTION # 119
Which three configuration parameters must match on all switches within the same MSTP region?
(Choose three.)
- A. VLAN to instance mapping
- B. bridge priority
- C. configuration name
- D. revision level
- E. region name
Answer: A,D,E
Explanation:
When enabling MSTP, you define one or more MSTP regions. An MSTP region defines a logical domain where multiple spanning-tree instances (MSTIs) can be administered independently of MSTIs in other regions, setting the boundary for bridge protocol data units (BPDUs) sent by one MSTI. An MSTP region is a group of switches that is defined by three parameters:
Region name - User-defined alphanumeric name for the region.
Revision level - User-defined value that identifies the region.
Mapping table - Numerical digest of VLAN-to-instance mappings.

NEW QUESTION # 120
Your enterprise network uses routing instances to support multitenancy. Your Junos devices use BGP to peer to multiple BGP devices. You must ensure that load balancing is achieved within the routing instance.
Which two statements would accomplish this task? (Choose two.)

- C. Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding- table] hierarchy.
- D. Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy.
Answer: C,D
Explanation:
To enable these features on a Layer 3 VPN routing instance, include the vpn-unequal-cost equal- external-internal statement at the [edit routing-instances routing-instance-name routing-options multipath] hierarchy level and the vrf-table-label statement at the [edit routing-instances routing- instance-name] hierarchy level.

NEW QUESTION # 121
You are implementing the route summarization feature of OSPF. Which two results do you achieve in this scenario? (Choose two.)
- A. It helps in migrating to future multi-area OSPF network designs.
- B. It provides optimal routing in the network.
- C. It reduces the impact of topology changes on a device.

NEW QUESTION # 124
There are two BGP routes to 10.200.200.0/24 received from two external peers. Route 1 comes from a neighbor with a router ID of 10.10.100.1 and a peer IP address of 10.10.30.1, and route 2 comes from a neighbor with a router ID of 10.10.200.1 and a peer IP address of 10.10.50.1. Both routes have the same MED value, origin value, AS path length, and local preference number. In this scenario, which statement is correct about the active route?
- A. Route 2 will be active because of the router ID.
- B. Route 1 will be active because of the peer IP address.
- C. Route 1 will be active because of the router ID.
- D. Route 2 will be active because of the peer IP address.
Answer: C
Explanation:
The router determines the router ID for each peer that advertised a path to the route destination.
A lower router ID value is preferred over a higher router ID value.
The router determines the peer ID for each peer that advertised a path to the router destination. A lower peer ID value is preferred over a higher peer ID value. The peer ID is the IP address of the established BGP peering session.

You have configured class mode power management on an EX4300 to provide PoE power to telephone and security camera equipment. You want to ensure that security camera power takes priority over telephone power.
Which two actions would solve this problem? (Choose two.)
- A. Set the power priority to high on ports connected to security cameras.
- B. Set the maximum power settings on ports connected to security cameras.
