Question 32

You have a multinode HA default mode deployment and the ICL is down.

In this scenario, what are two ways that the SRX Series devices verify the activeness of their peers? (Choose two.)

Options:

Custom IP addresses may be configured for the activeness probe.

Fabric link heartbeats are used to verify the activeness of the peers.

Each peer sends a probe with the virtual IP address as the destination IP address.

Each peer sends a probe with the virtual IP address as the source IP address and the upstream router as the destination IP address.

Answer:

A, D

Explanation:

Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References

Understanding the Scenario:

Multinode HA Default Mode Deployment:

In a chassis cluster, two SRX devices operate together to provide high availability.

ICL (Inter-Cluster Link) is Down:

The control and fabric links between the nodes are not operational.

Objective:

Determine how the SRX devices verify each other's activeness without the ICL.

Option A: Custom IP addresses may be configured for the activeness probe.

Explanation:

When the control link is down, SRX devices use an ICMP ping-based activeness probe to check the peer's status.

Custom IP addresses can be configured as probe targets to verify the peer's activeness.

[Reference:, "You can configure the SRX Series device to send activeness probes to a configured IP address to verify the peer's state when the control link is down.", Source: Juniper Networks Documentation - Control Link Failure Detection, Option D: Each peer sends a probe with the virtual IP address as the source IP address and the upstream router as the destination IP address., Explanation:, The SRX devices send ICMP probes to an upstream device using the redundancy group's virtual IP address as the source., This helps determine if the peer node is still active by verifying network reachability., Reference:, "When the control link fails, each node sends ICMP pings to the configured probe addresses using the redundancy group's virtual IP address as the source.", Source: Juniper Networks Documentation - Chassis Cluster Control Link Failure, Why Options B and C are Incorrect:, Option B: Fabric link heartbeats cannot be used because the ICL (which includes the fabric link) is down., Option C: Probes are sent to upstream devices, not using the virtual IP address as the destination., Conclusion:, The correct options are A and D because they accurately describe how SRX devices verify activeness without the ICL., ]

Question 33

You want to configure the SRX Series device to map two peer interfaces together and ensure that there is no switching or routing lookup to forward traffic.

Which feature on the SRX Series device is used to accomplish this task?

Options:

Transparent mode

Secure wire

Mixed mode

Switching mode

Discussion

Question 34

internal webserver www.juniper.net using domain name.

Questions 34

Referring to the exhibit, which two Junos features are required to accomplish this task? (Choose two.)

Options:

DNS doctoring

proxy ARP

persistent NAT

STUN

I used Cramkey Dumps to prepare and a lot of the questions on the exam were exactly what I found in their study materials.

Eric Sep 13, 2024

Really? That's great to hear! I used Cramkey Dumps too and I had the same experience. The questions were almost identical.

Honey

I highly recommend it. They made a big difference for me and I'm sure they'll help you too. Just make sure to use them wisely and not solely rely on them. They should be used as a supplement to your regular studies.

Antoni Oct 25, 2024

Good point. Thanks for the advice. I'll definitely keep that in mind.

Robin

Cramkey is highly recommended.

Jonah Oct 16, 2024

Definitely. If you're looking for a reliable and effective study resource, look no further than Cramkey Dumps. They're simply wonderful!

Yusra

I passed my exam. Cramkey Dumps provides detailed explanations for each question and answer, so you can understand the concepts better.
