New Cisco 300-320 Exam Dumps Collection (Question 8 - Question 17)
Question No: 8
The network engineering team is interested in deploying NAC within the enterprise network to enhance security. What deployment model should be used if the team requests that the NAC be logically inline with clients?
A. Layer 2 in-band
B. Layer 2 out-of-band
C. Layer 3 in-band
D. Layer 3 out-of-band
Answer: C
Explanation:
https://www.cisco.com/c/en/us/products/collateral/security/nac-appliance-clean-access/product_data_sheet0900aecd802da1b5.html
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, andremediation)
https://www.cisco.com/c/en/us/products/collateral/security/nac-appliance-clean-access/prod_qas0900aecd802da200.html
Q. Does an in-band deployment require the placement of multiple Cisco NAC Servers at the access layer?
A. No. The Server is logically in-line, not physically. This permits the placement of the Server at the core.
So, logically = layer 3 and inline = in-band
Question No: 9
What feature is a benefit of using Cisco UCS blade servers for data center virtualization?
A. guest VM high availability
B. converged LAN and SAN infrastructure
C. host based etherchannel
D. built-in hypervisor
Answer: B
Question No: 10
Which two network management capabilities that are embedded in Cisco IOS Software will baseline existing application traffic? (Choose two.)
A. Syslog
B. AutoQoS
C. NetFlow
D. SNMP
E. NBAR
F. Logging
Answer: C,E
Question No: 11
"High Availability and Cisco NSF with SSO The main objective in building a highly available data center network design is to avoid TCP session breakage while providing convergence that is unnoticeable, or as fast as possible. Cisco nonstop forwarding (NSF) with stateful switchover (SSO) are supervisor redundancy mechanisms that provide intrachassis SSO at Layers 2 to 4." QUESTION NO: 161
When designing remote access to the Enterprise Campus network for teleworkers and mobile workers, which of the following should the designer consider?
A. It is recommended to place the VPN termination device in line with the Enterprise Edge firewall, with ingress traffic limited to SSL only
B. Maintaining access rules, based on the source IP of the client, on an internal firewall drawn from a headend RADIUS server is the most secure deployment
C. VPN Headend routing using Reverse Route Injection (RRI) with distribution is recommended when the remote user community is small and dedicated DHCP scopes are in place
D. Clientless SSL VPNs provide more granular access control than SSL VPN clients (thin or thick), including at Layer7
Answer: D
Question No: 12
With respect to address summarization, which of the following statements concerning IPv4 and IPv6 is true?
A. The potential size of the IPv6 address blocks suggests that address summarization favors IPv6 over IPv4.
B. Role based addressing using wildcard masks to match multiple subnets is suitable for IPv4, but unsuitable for IPv6.
C. In order to summarize, the number of subnets in the IPv4 address block should be a power of 2 while the number of subnets in the IPv6 address block should be a power of 64.
D. WAN link addressing best supports summarization with a /31 subnet for IPv4 and a /126 for IPv6.
Answer: B
Explanation:
http://www.ciscopress.com/articles/article.asp?p=1763921
"For IPv6 access lists, the wildcard masks are not usually used. All source and destination addresses are notated in the form of prefixes. Therefore, it is important that subnets that are to be grouped in an access list falling within a summarized address range."
Question No: 13
Which statement about IPS and IDS solutions is true?
A. IDS and IPS read traffic only in inline mode.
B. IDS and IPS read traffic only in promiscuous mode.
C. An IDS reads traffic in inline mode, and an IPS reads traffic in promiscuous mode.
D. An IDS reads traffic in promiscuous mode, and an IPS reads traffic in inline mode.
Answer: D
Question No: 14
Which two of these correctly describe Fibre Channel? (Choose two.)
A. supports multiple protocols
B. works only in a shared or loop environment
C. allows addressing for up to 4 million nodes
D. allows addressing for up to 8 million nodes
E. provides a high speed transport for SCSI payloads
F. may stretch to a distance of up to 100 km before needing extenders
Answer: A,E
Explanation: https://www.safaribooksonline.com/library/view/foundation-learning- guide/9780132652933/ch06.html
"Fibre Channel includes these features:
u2022 Addressing for up to 16 million nodes
u2022 Loop (shared) and fabric (switched) transport options
u2022 Host speeds of 100 to 400 MBps, or an effective throughput of 1 to 4 Gbps on the fabric
u2022 Segment distances of up to 6 miles (10 km)
u2022 Support for multiple protocols"
Question No: 15
Which three options are features of IP SLAs? (Choose three.)
A. enables verification of service guarantees
B. dynamically adjusts QoS parameters
C. validates network performance and metrics
D. initiates failover for saturated links
E. proactively identifies network related issues
Answer: A,C,E
Question No: 16
In a base e-Commerce module design, which routing statement is correct?
A. Routing is mostly static.
B. Hardcoded IP addresses are used to support failover.
C. Inbound servers use the CSM or ACE as the default gateway.
D. VLANs between the access layer switches are used for FHRP protocols.
Answer: A
Explanation: https://www.safaribooksonline.com/library/view/foundation-learning-guide/9780132652933/ch07.html
"Base Design Routing Logic Routing in this e-commerce module design is mostly static, using VIP addresses to support failover."
Question No: 17
Which of the following is most accurate with respect to designing high availability within the Enterprise Campus network?
A. High availability at and between the Distribution and Access layers is as simple as redundant switches and redundant Layer 3 connections
B. Non-deterministic traffic patterns require a highly available modular topology design
C. Distribution layer high availability design includes redundant switches and Layer 3 equal-cost load sharing connections to the switched Access and routed Core layers, with a Layer 3 link between the distribution switches to support summarization of routing information from the Distribution to the Core
D. Default gateway redundancy allows for the failure of a redundant Distribution switch without affecting endpoint connectivity
