New Cisco 300-320 Exam Dumps Collection (Question 3 - Question 12)
Q1. AutoQoS is used to implement VoIP in the enterprise, but the trust option is not configured on the interface. Which network management Cisco IOS capability classifies the voice traffic?
A. NetFlow
B. SNMP
C. IP SLAs
D. NBAR
Answer: D
Q2. Which NAC design model matches the following definitions?
NAS is deployed centrally in the core or distribution layer. Users are multiple hops away from the Cisco NAS.
After authentication and posture assessment, the client traffic no longer passes through the Cisco NAS.
PBR is needed to direct the user traffic appropriately
A. Layer 3 in-band virtual gateway
B. Layer 3 out-of-band with addressing
C. Layer 2 in-band virtual gateway
D. Layer 2 out-of-band virtual gateway
Answer: B
Explanation:

Passing traffic mode
u2022 Virtual gateway (bridged mode)
u2022 Real IP gateway (routed mode)
Client access mode
u2022 Layer 2 (client is adjacent to the Cisco NAC Server)
u2022 Layer 3 (client is multiple hops from the Cisco NAC Server)
Traffic flow model
u2022 In-band (Cisco NAC Server is always in-line with user traffic)
u2022 Out-of-band (Cisco NAC Server is in-line only during authentication, posture assessment, and remediation)
Q3. Refer to the exhibit.
Which functionality must be enabled on router A to connect two networks for translating private addresses into "legal" public addresses on a one-for-one basis?
A. PAT
B. NAT
C. VLAN
D. GARP
E. PPP
Answer: B
Q4. Which three options are recommended practices when configuring VTP? (Choose three.)
A. Set the switch to transparent mode.
B. Set the switch to server mode.
C. Enable VLAN pruning.
D. Disable VLAN pruning.
E. Specify a domain name.
F. Clear the domain name.
Answer: A,D,E

Q5. Source traffic is sent to a VIP on an SLB device, which in turn is routed to the destination server. Return traffic is policy-based routed back to the SLB. Which SLB design has been implemented?
A. router mode
B. inline bridge mode
C. one-armed mode
D. two-armed mode
Answer: D
Explanation:
"In the one-armed approach, the SLB VIP and the physical servers are in the same VLAN or subnet.
In the two-armed approach, the SLB device routes traffic to the physical server subnet, which can be a
private subnet."
Q6. When considering the design of the E-Commerce topology which of the following are true?
A. One-armed SLB design with multiple security contexts removes the need for a separate firewall in the core layer
B. Two-firewall-layer SLB design considers the aggregation and access layers to be trusted zones, requiring no security between the web, application, and database zones
C. One-armed SLB design with two firewall layers ensures that non load-balanced traffic still traverses the ACE so that the health and performance of the servers is still being monitored
D. In all cases there will be configuration requirements for direct access to any servers or for nonload-balanced sessions initiated by the servers
Answer: A
Q7. A company implemented VoIP in a campus network and now wants a consistent method to implement using AutoQoS. Which two parameters must be considered before AutoQoS is configured? (Choose two.)
A. CEF must be enabled.
B. AutoQoS is available only on routers.
C. Traffic discovery must be performed manually.
D. No service policy can be applied already.
E. Manual traffic analysis must be performed.
Answer: A,D
Q8. Which of the following two statements about Cisco NSF and SSO are the most relevant to the network designer? (Choose two.)
A. You can reduce outages to 1 to 3 seconds by using SSO in a Layer 2 environment or Cisco NSF with SSO in a Layer 3 environment.
B. SSO and NSF each require the devices to either be graceful restart-capable or graceful
restart-aware.
C. In a fully redundant topology adding redundant supervisors with NSF and SSO may cause longer convergence times than single supervisors with tuned IGP timers
D. The primary deployment scenario for Cisco NSF with SSO is in the Distribution and Core layers.
E. Cisco NSF-aware neighbor relationships are independent of any tuned IGP timers
Answer: B,C
Explanation: https://www.safaribooksonline.com/library/view/foundation-learning- guide/9780132652933/ch02.html
"In a fully redundant topology with tuned IGP timers, adding redundant supervisors with Cisco nonstop forwarding (NSF) and stateful switchover (SSO) may cause longer convergence times than single supervisors with tuned IGP timers."
"A graceful restart-aware neighbor is required so that graceful restart -capable systems can rebuild their databases and maintain their neighbor adjacencies across a switchover."
Q9. Which two statements about both FCIP and iSCSI are correct? (Choose two.)
A. They support file-level storage for remote devices.
B. They require high throughput with low latency and low jitter.
C. Their purpose is to provide connectivity between host and storage
D. They support block-level storage for remote devices.
E. Their purpose is to provide connectivity between separate wide-area SANs.
Answer: D,E
Q10. Which route summarization most efficiently reduces perceived network complexity that is composed of
subnetworks ranging from 172.16.20.0/24 to 172.16.36.0/24?
A. 172.16.8.0/21
B. 172.16.8.0/19
C. 172.16.20.0/20
D. 172.16.0.0/18
E. 172.16.20.0/19
Answer: D
