In the exhibit, which statement about the ABR between Area 8 and Area 2 is true?

  1. The router has connectivity to all areas.

Answer: D

Question No: 172 – (Topic 3)

You want to control bursts of HTTP traffic entering your SRX Series Gateway. To support varying requirements, interfaces ge-0/0/0 through ge-0/0/3 should each be rate-limited

separately, using the same parameters.

What is the correct way to meet these requirements?

  1. Configure a single policer and apply it directly on the appropriate interfaces.

  2. Configure four policers and apply each one directly on the appropriate interface.

  3. Configure a policer and reference it in a firewall filter that uses the interface-specific option; apply the filter to the appropriate interfaces.

  4. Configure four policers and reference them all in a firewall filter; apply the filter to the appropriate interfaces.

Answer: C

In the exhibit, you see a configuration for CoS. Incoming traffic with specific IP precedence bits should be mapped to a forwarding class named best-effort. A classifier named normal- traffic is defined.

What must you add to complete this configuration?

  1. Include the option q-pic-large-buffer under the chassis hierarchy to accommodate the new code points.

  2. Apply classifier normal traffic to the interface hierarchy under the class-of-service stanza.

  3. Configure a rewrite marker on the ingress Gigabit Ethernet interface.

  4. Add code point values for the expedited-forwarding forwarding class as well as the best- effort forwarding class.

Answer: B

Question No: 174 – (Topic 3)

You must configure your access switch with more than 3000 VLANs and you want the ability to load-balance across them.

Which spanning-tree approach has the least impact on control-plane performance?

  1. Configure your access switch with a load-balancing policy and apply it under [edit

    protocols rstp].

  2. Configure your access switch for Rapid-PVST .

  3. Configure your access switch for MSTP, incorporating the use of MSTIs.

  4. Configure your access switch for both VSTP and RSTP.

Answer: C

Question No: 175 – (Topic 3)

A network administrator is configuring CoS on a switch and assigns forwarding classes call-sig and critical to the same queue number per the configuration below:

class-of-service { forwarding-classes {

class best-effort queue-num 0; class bulk-data queue-num 1; class critical queue-num 3; class voice queue-num 6; class call-sig queue-num 3;

}

}

Based on the configuration, which option prioritizes call-sig traffic over critical traffic?

  1. Assign call-sig and critical to different schedulers.

  2. Assign call-sig and critical to different scheduler maps.

  3. Assign a loss priority of high to the packets in the critical forwarding class and configure drop profiles in the scheduler configuration.

  4. Assign a loss priority of high to the packets in the critical forwarding class and set priority high in the scheduler configuration.

Answer: C

Question No: 176 – (Topic 3)

You are configuring CoS classifiers and want to use both BA and MF classification. After applying the configuration, you realize that the classifiers have a conflict.

Which statement is true?

  1. BA classification overrides MF classification.

  2. MF classification overrides BA classification.

  3. Neither classification method is applied.

  4. Both classifications are applied randomly.

Answer: B

Question No: 177 – (Topic 3)

Referring to the exhibit, which three statements describe correct behavior of Switch A? (Choose three.)

  1. Switch A allows complete access to all users connected to port ge-0/0/2 that log in with their correct user credentials.

  2. Switch A allows complete access to all users connected to port ge-0/0/0 that log in with their correct user credentials.

  3. Switch A allows complete access to the second user that connects to port ge-0/0/1 with its correct credentials only after the first user logs out.

  4. Switch A allows complete access to all users connected to port ge-0/0/0 without authentication after the first user has logged in with its correct user credentials.

  5. Switch A allows complete access to all users connected to port ge-0/0/1 that securely log in using HTTPS with their correct user credentials.
